This document defines technical requirements for materials supplied to Quad/Graphics Sp. z o.o.
(the Company), general quality standards of products produced by the Company, quality
controlled parameters, as well as definitions of acceptable product.
Master Materials – materials used as a master for colours in the printing process. A master
material can be a signature accepted by the Client or a certified contract proof. A master material
can also be a non-certified proof or print from previous editions, however colour on such a
master is treated only as a general reference.
Contract Proof – master material faithfully simulating the real effect of the printing process in a
given technology. The basis to consider proof as a contract proof is its certification.
Proof Certification – process of checking of proof workmanship accuracy, consisting of
determining the colour difference between values measured on test strip fields placed on the
proof, and target values. Target values are determined on the basis of the ICC profile, with which
the proof is executed. Proof certification may be carried out at the Client’s facility or at the
Certified Proof – proof with attached results of colour difference ΔE measurement, in which the
colour difference may not exceed the tolerance limit defined in Basic Quality Standards.
ICC Profile – digital file containing colour characteristics of a given device. That profile meets
requirements specified in ICC Specification.
Distribution List – document in the form of a table containing information concerning the
method of preparation of dispatch of particular issue batches, including quantities (package
standard, pallets, quantity of pallets), issue versions, dispatch addresses, method of sorting,
packaging and marking of issues.
Type Page – print area of page. There are, for instance, one-, two- and three-column type pages.
Type Page Editing – combining of advertising and editorial materials into one type page.
Trim Box – area defined in PDF format which represents the net page format (after printing and
trimming). Documents delivered to the Company must have a defined trim box. Trim box setting
can be checked in Adobe Acrobat Professional
Bleed – area of an image extending to the crop marks defining net page size. Lack of bleed causes
defect generation during bookbinding operations.
Self Cover – cover printed together with body pages of the publication as part of a single section
(signature). The outer page of the signature serves as the cover. During binding, the cover is not
fed separately, since it is part of one of the sections being bound together.

1. Preparation and Delivery of Digital Materials
1.1. Digital materials should be delivered via the Internet by means of InSite, using the tools
included. Location and data enabling access – login (user name) and password are made
available by the Customer Service Representative serving your company. Logging in to InSite
is possible via a web browser (Internet Explorer on the Windows operating system, Safari on
the Mac OS X system) using the addresses:
The name of a dispatch (folders) may not include any local (diacritic) language signs, spaces
and special characters (* > ! ? < : / \ etc.). Only the following characters are permitted: a b c d
e f g h i j k l m n o p q r s t u v w x y z 1 2 3 4 5 6 7 8 9 0 and _.
Digital materials can also be delivered by means of FTP (File Transfer
Protocol) to the designated server:
Location and data enabling access to the server – login (user name) and password – are
made available by the Customer Service Representative serving your company.
Digital materials may also be delivered on most popular digital data carriers formatted for
PC or Mac systems (CD-ROM or DVD). Under no circumstances should the Printing House
download files from the Client’s server. Digital materials should not be sent via e-mail.
1.2. Pages should be prepared in the following file formats:
• Postscript level 1, 2 or 3 (separated or composite),
• PDF 1.4 – 1.6 (Acrobat 5-7),
• PDF/X-1a:2001,
The Company recommends composite files, scale: 1:1, orientation: Portrait. Using both
composite and separated files in the same publication is allowed.
A separate file should be generated for each page and spine, whose width should be
previously agreed with the Title Supervisor. Separate files for the left and right side should
be also created for spreads.
1.3. A type page montage of advertisements should be made by your editorial staff.
When particular editorial or advertising type pages are prepared in a format other than
those stated, it is necessary to attach a dummy with the accurate determination of type page
location, scaling percentage and scaling method (proportional or disproportionate).
Bitmap resolution for photographs in digital files:
250 dpi
300 dpi
450 dpi
The Printing House will reduce to 300 dpi the resolution of all colour and greyscale
bitmaps whose resolution exceeds 450 dpi.
By supplying an image with a lower resolution than the minimum recommended above,
the Client indicates acceptance of an inferior quality reproduction of that image in print.
1.4. The resolution of 1-bit images shall not exceed 2400 dpi.
1.5. Graphic elements of the page must not include attached profiles (no tagged profiles).
Page 4 of 18
1.6. Graphic elements of the page must not include OPI (Open Prepress Interface) comments.
1.7. Supplied files must not contain copy-dot elements without prior agreement
with the Company.
1.8. Before sending the materials to the Printer it is recommended to preflight the files with the
use of an appropriate software applications, such as Adobe InDesign (version CS4 or
higher), | Adobe Acrobat (version 6.0 or higher) or Enfocus PitStop to detect the most
frequently occurring errors.
1.9. The client must indicate to the Customer Service Representative the differences between
versions/mutations and provide the naming scheme used for the files. The name of a file
should contain a description of the version.
1.10. The date of delivery of digital materials shall be considered the date of delivery of
completed materials not requiring correction.
1.11. Failure to keep these terms of delivery may cause delays in shipping the finished product,
for which the Company shall not be responsible.
2. File Generation
2.1. The Company recommends composite files in PDF generated with Adobe or QuarkXpress
applications. The Company allows also files created by PS file conversion using Adobe Acrobat
Distiller in version 5.0 or later according to manual available for download on website:
2.2. In case of questions, please send us sample files and contact your Customer Service
Representative. We also recommend visiting:
2.3. In case of starting cooperation it is obligatory to send us sample files.
3. Total Area of Ink Coverage
3.1. Total Area of Ink Coverage (TAC), is specified as a percentage. There is a maximum
percentage total ink coverage determined for the certain paper types and it can be used
during the files assembly (TAC). The printer will not take the responsibility for any defects
caused by exceeding of TAC. TAC values for each paper type for the corresponding profiles
are given in the table below:
Paper Group
MWC, WFC - sheet fed presses
MWC, WFC - Web presses
Page 5 of 18
4. File Naming
4.1. All files delivered to the Company should be named according to the following scheme:
Publication body, publication with self cover (see Definitions on page 3):
where: nnn – no. of the page in publication (e.g. 001, 002); KOD – title code (e.g. POL –
ww – Issue no. (e.g. 04);
v1 – file version; use if files have more than one language, price, etc. version. Each
version should be marked with a consecutive number (e.g. v1, v2, etc.);
spot – special colour employed; use when colours different than CMYK were used
in the file;
a – file version; use if it is necessary to upload file correction (consecutive
versions should be marked as b, c, etc.);
ext – file extension (e.g. pdf, ps).
first page of a publication (self cover)
first file correction of page three
file dedicated for page 4 of the publication
005_POL_04_spot_b.pdf second correction of the file dedicated for page 5,
file contains special colour
where: cover – information that file contains a cover (do not use when
publication contains self cover);
nnn – consecutive no. of cover page in publication
(e.g.: 001_cover...; 002_cover...; 003_cover...);
… – for other symbols see above.
first correction of page 1 of a cover, cover contains
special colour
file dedicated for page 2 of the cover
second correction of a file dedicated for page 3 of
the cover
Other cases:
If there is more than one file per page (e.g. one with content and one with advertising),
letters should be added to the page number:
Example: 001a_POL_04.pdf
the first file for page 1
the second file for page 1
In such cases, attach a dummy showing the layout of page components.
Page 6 of 18
4.2. The Company has a right to impose additional charges for ensuring product quality, if the
file naming scheme is not followed.
4.3. The name of the files may not include any local (diacritic) language signs, spaces and special
characters (* > ! ? < : / \ etc.). Only the following characters are permitted: a b c d e f g h i j k l
m n o p q r s t u v w x y z 1 2 3 4 5 6 7 8 9 0 and _.
It is absolutely crucial that the file naming scheme be followed, since automatic processing of
the files depends on their names.
5. Layout
5.1. Each page should have bleed of at least 3 mm from each side.
5.2. Important text or graphic elements should be positioned at least 5 mm from the trim edge.
5.3. When perfect binding, remember that pages 2 and 3 of the cover and the first and last page
of the body will have 3 mm from the backbone glued through side gluing, which will reduce
the effective format of the spreads. If no correction is made, part of the picture will be “cut
out” as a result of the binding process. The page format should stay the same – it is only the
size of the image area that should be subject to change.
5.4. A trim box size must be set in accordance with the net page format.
5.5. Reduction of effective page format will occur as a result of incomplete copy opening in
the perfect bound book.
5.6. When in-line gluing (on a printing press), the minimum distance of text and other
graphic elements from the backbone should be 6 mm, due to the phenomenon
described in items 5.3. and 5.5.
5.7. Moving the illustrations several millimeters onto the adjacent page will not correct the file
for folding and binding tolerance (see Basic Quality Standards).
5.8. For the sake of print aesthetics and tolerance of folding and binding one type line of small
type size should not be placed on the adjacent type pages. Dividing of text between type
pages in the middle of a word is impermissible.
5.9. Minimum type size for one colour printing is:
• 6 pt for one-element fonts,
• 7 pt for two-element fonts.
Minimum type size for more than one colour or drop out type is:
• 8 pt for one-element fonts,
• 10 pt for two-element fonts.
5.10. Minimum permissible line thickness is 0.2 pt. Lines printing in more than one colour or
dropping out of colour should have a thickness of at least 0.75 pt.
5.11. In order to obtain richer black depth and avoid picking effect in solid areas, black should be
generated from 4 colours. Recommended formulas are C 70, M 60, Y 60, K 100 for coated
papers (MWC, LWC) and C 50, M 40, Y 40, K 100 for uncoated papers (SC type and
Page 7 of 18
5.12. Registration inaccuracy is avoided by trapping, (minimal overlapping of colours on one
another). When submitting composite files, which are preferred by the Company, the Client
should not make trapping. This process is carried out by the Company, provided the Client
does not express any reservations. If Client submits separated files the Company cannot
introduce trapping. Separated files trapping must be made by the Client. Recommended
trapping value is 0.05 mm (0.144 pt).
When reversed print against black background of 4 colours is needed, negative trappings for
CMY colours of size 0.17 mm (0.5 pt) are recommended.
If spot ink is used for printing (Pantone, metallic colour), a CMYK spread must be made in
the direction of the spot colour (Pantones, metallic colours).
5.13. Black text smaller than or equal to 24 pt set against a colour background must be
overprinted. The exception is the text (K or CMYK) on spot colours (Pantones, metallic
colours), where knockout-should be applied, according to 5.12 or K or CMYK spread
towards the spot colour. All graphic sprinted over spot colours (such as shades) must also
be selected and spread in a similar manner. This is the only way we can ensure proper
representation of all elements.
5.14. Black text larger than 24 pt may be made of 4 colours according to the formula
specified in item 5.11.
5.15. All graphic elements must be prepared within the CMYK space. Graphic elements and
photographs in other colour spaces, such as RGB or Lab, are automatically converted to the
CMYK space utilizing ICC ISO Coated v2_300_eci profile by means of perceptual rendering
intend. All spot colours used, e.g. from the Pantone® system, must be changed to CMYK.
Spot colours may be used only in agreement with the Company.
5.16. “Pushing out” of sections.
In saddle-stitched binding there is a phenomenon called “pushing out” of sections. Internal
sections are moved away from the backbone by values dependent on paper thickness and
signature number. This phenomenon causes a reduction of the effective page width and
displacement of graphic content of the page, which in the worst case scenario may lead to
the cutting of typography or graphic elements situated near the outside trim edge. To
prevent this the outside margin of individual pages of consecutive signatures should be
increased by the values given in the table below, keeping the other margins and page size
unchanged. If in the files the Client has not foreseen the push-out effect of the sections, the
Printing House may create a push-in effect on its own when it considers necessary to obtain
a good quality final product. We would also like to inform you that all graphic elements and
texts on pages will be reduced by the value of this push-out effect depending on the paper
weight (according to the table below). For instance, from 0 mm value for the first pages of
the first sheet to 4 mm value at the centerfold of the eighth sheet for 70 g/m2 paper weight.
Such changes in images are invisible to the eye and they can be verified only by measuring
the chosen objects.
Page 8 of 18
54 g/m2
60 g/m2
70 g/m2
80 g/m2
90 g/m2
6. Separation
6.1. ICC profiles used for generating separations should be adjusted to the paper grade on which
the printing is done according to the ISO 12647-2 standard. ICC profiles are made available to
clients by your Customer Service Representative. Profiles recommended by the Company
should be used. Using other ICC profiles is permissible only in agreement with your Customer
Service Representative.
6.2. The Company takes no responsibility for the final product, if files have not been prepared in
accordance with the above guidelines or if they contain objects imported directly or indirectly
from CorelDraw or AutoCad software. The Printing House also has the right to refuse the
acceptance of any files not consistent with specifications.
All additional operations aimed at correcting the files in order to reach consistency with
specifications and all changes made by the Company at the Client’s request are considered
additional paid service.
7. Master Materials
7.1. Attaching a contract proof to each page is recommended.
7.2. Contract proofs should be made after the last correction of files submitted for printing.
7.3. The ICC profile acquired by the Customer Service Representative should be used for
making a contract proof.
7.4. Title, publication number, page number, file name, date of proof performance and name of the
ICC profile used should be included on each contract proof. Also, a control strip must be
placed on each contract proof. Use a Ugra/FOGRA Control Strip or the one provided by the
Customer Service Representative. Lack of description or strip makes it impossible to use a
contract proof as a master material in the Company.
7.5. When the proof is accepted by the Client, the signature accepted and signed by the Client
becomes a master material for the offset operator.
Page 9 of 18
7.6. Prints from previous editions are not contract proofs; they may serve only as a reference
point for the offset press operator. Using that type of master material entails the possibility of
obtaining a different colour as a result of lack of information concerning the preparation of
materials and the printing process or as a result of a different placement of the type page on
the sheet.
7.7. If the Client does not deliver contract proofs, the print will be carried out according to Lab
coordinates of primary colours corresponding to the ECI profile of the job and dot gain
specified by ISO 12647-2 standard for a given paper grade.
7.8. Detailed requirements concerning methods of control proof preparation are included in
Basic Quality Standards (chap. IV, item 1.1.2)
7.9. Pantone® for the title must be given to the person leading this title minimum 48 hours before
the release date of the respected cover/signatures printing materials.
8. Additional Orders – Inserting
8.1. Information concerning insert and delivery dates
8.1.1. Detailed information on the insert and the inserting process which is to be provided by the
Client to the Customer Service Representative, and delivery description and the Company`s
acceptance criteria for the insert are listed in the appendix to the specification: “SUPPLYING
INSERTS AND PROMOTIONAL MATERIALS.” If the inserts/promotional materials are not
prepared in accordance with the requirements, the Company reserves the right to charge
the Client for additional activities carried out by the Company, like sorting, unpacking or
9. Inkjet
9.1. Requirements and recommendations concerning addressing should be discussed and
agreed upon with the Customer Service Representative for each project run. This should
include material preparation and delivery and other requirements for executing the order.
9.2. Overprint location – the location on the printed piece in which the overprint is to be made
- should be discussed and agreed upon for each print run (e.g. label on the type page,
address coupon, label on foil package).
9.3. Label – standard; minimum size of the label is a white area 90 mm wide and 40 mm high.
9.4. Overprint layout – the following data should be given: number of lines and their location in
the label the reference to each line in the field name (actual name saved in the database) or
the number of the characters beginning and ending the field the number of characters for
individual records.
9.5. Type face and its size – for dot matrix printers it is specified by the number of dots, while
for graphic printers by typeface (MS Windows).
9.6. Sorting criteria – give criteria specified by the post that will receive the shipments.

10. Data bases for customisation
10.1. All materials necessary for customisation (data intended for customisation, reports, etc.)
must be placed on the server of the printing house not later than on the date specified in
the time schedule (appendix to the printing order).
10.2. Data intended for customisation must be delivered by FTP (File Transfer Protocol) to the
following server:
Login and password are sent to the designated contact person.
The account contains two folders:
INCOMING – here the client uploads files
OUTGOING – here files are stored for the client on request
In extraordinary circumstances the client may send a base by e-mail to: after prior agreement with the Title Manager. The base should be
zipped and encrypted. Password to the base should be sent by a separate e-mail. Messages
which do not comply with this standard will be deleted automatically.
10.3. Accepted file formats:
with stated code page of the file.
EXCEL – only XLS files, other files with activated macros and functions will be deleted from
the server. Excel cells may not contain more than one line and non-printable characters may
not be used. If the above requirements are not met, the client will be charged with additional
costs of work.
ACCESS – files in this format may be handled after prior agreement.
10.4. Method of preparing files for customisation
- fixed-length field and fixed-length record file. Switching to next record should be carried
out by <CR><LF> (CR – carriage return, LF – line feed). For all fields the data type should
be set to text.
- file with fields separated by a delimiter. A TAB or | (vertical bar, hexadecimal representation 0x7C)
may be used as a filed delimiter. If a different delimiter is used to separate the fields, errors may
occur during data processing. End of a record should be marked with <CR><LF> (CR
– carriage return, LF – line feed). The sent base should be accompanied by a description
containing names of the fields in the base, information whether a particular field should
be used during customisation and a description.
Page 11 of 18
A description containing the following information should be enclosed with each base:
• number of records
• number of copies
• field delimiter (only for bases with fields separated by a delimiter)
• post office – state the name of the post office delivering mail
• country – name of the country to which the mail will be delivered
• names of the fields in the base
• a character which starts a given filed (only fixed-length field files)
• field length – number of characters in a given field (only fixed-length files)
• information whether a given field should be used during customisation
• field description
Layout template for fixed-length bases:
Field name
Pallet Alpha
10.5. Required fields
Address bases to be used for customisation should contain the following fields:
• item number – subsequent record number in the delivered address base filed in by zeros to
full field length (in the case of 5 character long fields subsequent record numbers should be
the following: 00001, 00002, 00003, etc.)
• surname
• first name
• name of the company/institution
• street and house/apartment number – a house/apartment number may be given in a
separate field
• post code – a post code and city name should not be given in one field. Such preparation of
Page 12 of 18
the address base may prevent proper preparation of mail for the post office
• city
• country name.
The printing house prefers the fields in the address base to be presented in the above-mentioned
order. Apart from the above-mentioned data the file may contain additional fields which should be
described in detail in the provided specification (“remarks” field), in a way which makes it possible to
unambiguously interpret the information contained therein.

1. Printing Process
1.1. Colour:
1.1.1. The colour of the finished product should be as close as possible to the colour of the properly
made contract proof supplied by the Client taking into consideration the specificity of offset print,
paper quality, proof characteristics and other factors affecting the colour of the copy.
1.1.2. Requirements concerning contract proofs
A control strip should be placed on each proof. Recommended control strips are the
UGRA/FOGRA strip or the strip supplied by Customer Service at the Client’s request. Each
proof delivered to the Company should have a certificate confirming its correctness.
Certification of contract proofs is based on the ISO 12647-7-2007 standard.
Acceptable proof
ΔEab primaries <5
ΔEab average of the control strip <3
ΔEab maximum <6
ΔEab substrate simulation <3
ΔH maximum of primaries <2.5
ΔH average of grey balance <1.5
Not acceptable proof
ΔEab primaries>5
ΔEab average of control strip > 3
ΔEab maximum >6
ΔEab substrate simulation >3
ΔH maximum of primaries >2.5
ΔH average of grey balance >1.5
Measuring conditions:
• white backing,
• illuminant D50,
• standard observer 2°,
• absolute value,
• no UV cut filter and no polarizing filter.
The proof must be made with the ICC profile provided by your Customer Service
Representative. The proof must be made with printing base-paper simulation.
1.1.3. If the proof is not made according to specification, it will not be considered
a contract proof. In such a case, the Company shall make a contract proof at the Client’s
expense. If the Client does not give his/her consent to make the proof, then the proof
supplied by the Client may be treated as the master material for the offset press operator.
However, this proof colour may not be attainable on press.
1.1.4. Optical densities of the printing process are selected in a way that ensures that Lab values
of solid CMYK patches are obtained on paper of a given grade and with given inks,
according to ISO 12647-2 standard tab. 2.
1.1.5. Printing control tolerances for particular colours in relation to the signature accepted by
the Client or by an authorized Printing House employee:
Solid Ink Density
Dot Gain
≤ ± 0.1
≤ ± 4%
Page 14 of 18
Not acceptable
> ± 0.1
> ± 4%
Measuring conditions:
• black backing,
• standard E (DIN),
• relative to paper,
• no polarizing filter.
1.1.6. Consistency of colours between the contract proof and the printed product is assessed
visually at D50 standard lighting as per ISO 3664:2000 standard.
1.1.7. If it is necessary to obtain optimal consistency with the master material, Lab values of
solid patches can go beyond tolerance limits specified in ISO 1247-2 standard.
1.1.8. In order to ensure the highest quality of colour reproduction relative to a correctly
made contract proof the Company may apply additional optimisation to input data.
1.2. Colour registration
1.2.1. Permissible deviation of register of colours printed consecutively one after another:
≤ 0.1 mm
Not acceptable
> 0.1 mm
1.2.2. Because of the automatic registration systems used on presses and the manner of their
operation, colour register tolerance may be temporarily exceeded. In such a case it
should be assumed that the error concerns a maximum of 200 signatures.
1.3. Fold and page arrangement
1.3.1. Permissible fold deviation from fold line:
Not acceptable
≤ ± 1 mm
> ± 1 mm
1.3.2. Permissible deviation of the arrangement of pages in the signature in relation to one
≤ ± 2 mm
Not acceptable
> ± 2 mm
1.3.3. A fold should be considered to have been made incorrectly when it causes a crumpling
of paper, creasing, etc., which makes it impossible to read the content or view an
1.4. Additional Pantone® colours
Because of possible lack of densitometric control of colour intensity, correct colour should
be considered to be colour that visually fits between sample (-) and sample (+) supplied by
the producer of the ink. Additional colours should be individually accepted by the Client.
Pantone® color system
Pantone colors are printed in accordance to the current Pantone® color system
issued on yearly basis. The printer will not take the responsibility for unmatched
colors compared to old Pantone® color system.
1.5. Gluing in line
On low-absorbing papers (MWC, LWC) there is a risk of “spreading” of glue outside the
gluing line. Permissible paper gluing width beyond the gluing line:
≤ 4 mm
Not acceptable
> 4 mm
Page 15 of 18
1.6. Perforating during printing tolerance from the theoretical perforation line concerning
longitudinal and lateral perforation:
Not acceptable
≤ 2 mm
> 2 mm
1.7. Register of picture and varnish layer in case of selective varnishing:
Not acceptable
≤ 1 mm
> 1 mm
1.8. Varnish layer
The varnish layer is considered incorrect when there are unvarnished spots on the surface
intended for varnishing no matter whether it is offset, dispersion or UV coating.
1.9. Due to heat-set web offset printing specificity the process is accompanied by smearing (ruboff). The Company will make all possible effort to minimize this phenomenon, but cannot
guarantee its complete elimination.
1.10. Due to heat-set web offset printing specificity the process is accompanied by fluting.
The Company will make all possible effort to minimize this phenomenon, but cannot
guarantee its complete elimination.
1.11. Error extent assessment
In each case the basis for determining the percentage of defective signatures shall be the
revision signatures put off by every ten thousand signatures or as agreed with the Client.
2. Bookbinding Process
2.1. Trim dimension
Permissible deviation of trim dimension in relation to nominal dimension measured for each
100 mm:
Not acceptable
Head and feet trim
≤ ± 1 mm
> ± 1 mm
Front trim
≤ ± 1 mm
> ± 1 mm
2.2. Trimming parallelism
Permissible deviation of parallelism of two binding edges when measured after folding the
book in half:
≤ ± 2 mm
2.3. Arrangement of pages
Not acceptable
> ± 2 mm
2.3.1. Permissible vertical deviation in arrangements of pages between signatures in the
finished copy:
Not acceptable
≤ ± 2 mm
> ± 2 mm
The permissible vertical deviation consists of the sum of deviations from
previous technological processes:
• permissible deviation of the fold from the fold line is ± 1 mm,
• permissible deviation between signatures ± 1 mm.
Page 16 of 18
2.3.2. Permissible vertical mismatch between cover and body:
Binding type
Perfect binding
≤ ± 2.5 mm
≤ ± 1.5 mm
Not acceptable
> ± 2.5 mm
> ± 1.5 mm
The permissible vertical mismatch consists of sum of deviations from previous
technological processes:
• folding tolerance within the limits of permissible deviations ± 1mm,
• deviations arising during sheet fed printing and cutting into single pieces (covers) ± 1mm,
• tolerance of feeding and application of the cover ± 0.5mm.
2.3.3. Permissible deviation of copy width between the cover and the body in perfect bound
and saddle-stitched copies (caused by shrinking of paper, humidity difference, basis
Not acceptable
≤ ± 1 mm
> ± 1 mm
2.4. The format deviation of master binding from the specified net format should fit within the
tolerance scope. Change of format of master binding in relation to the specified net format
may result exclusively from striving to keep the picture in the format.
2.5. Binding strength
2.5.1. Perfect binding
The strength of perfect binding is measured by means of Pulltester. The number of sheets
which should be tested in a single book is:
• 3 sheets spaced evenly in the copy for books of backbone ≤ 1 cm
• 5 sheets spaced evenly in the copy for books of backbone > 1 cm
≥ 4.5 N/cm
Not acceptable
< 4.5 N/cm
2.5.2. Saddle-stitching
Saddle-stitching is considered correct when signatures stay joined and do not tear apart
at the folds as a result of staples used and the number of staples corresponds to their
ordered amount (for one edge).
Staples shall be considered correct if:
• they firmly keep the joint of saddle-stitched book edges,
• the total length of staples does not cause overlapping of edges,
• the edges of staples are bent in the way specified in the order (flat-bent or rounded).
Staple position tolerance in the direction perpendicular to the spine:
≤ ± 1 mm
Not acceptable
> ± 1 mm
The strength of a saddle-stitched book is not measured, as in this case the obtained
result is not the strength of binding but the strength of paper.
2.6. Sheet cutting
Permissible deviations when cutting sheets into single pieces:
≤ ± 1 mm
Not acceptable
> ± 1 mm:

2.7. Off-line folding and perforations
2.7.1. Folding – permissible deviation of fold from nominal line of its location (on each fold):
Not acceptable
≤ ± 1 mm
> ± 1 mm
2.7.2. Permissible deviations of the made perforation from its nominal location:
≤ ± 1 mm
Not acceptable
> ± 1 mm
2.7.3. Final deviations of the executed folds and perforations are also affected by permissible
deviations arising during earlier technological processes, i.e. printing and cutting of the

2.8.1. Permissible deviations of Inkjet overprint position from the area intended for performing
≤ ± 5 mm
Not acceptable
> ± 5 mm
2.8.2. Permissible deviation of overprint on the label during saddle-stitching, perfect binding
and packing:
≤ ± 5 mm
Not acceptable
> ± 5 mm
2.8.3. Overprint shall be considered correct when it was placed and configured according to
specification (overprint layout, type) and all its elements are readable.
3. Delivery Acceptance Criteria
Delivery is considered consistent with the order when at least 98% of the product’s quality
parameters fall within the scope of tolerance permissible by this specification. The Printing
House reserves the right to have differences +/- 2 copies in packs.
Any possible comments or reservations should be submitted within 14 days of shipment.1
