Introduction
CreoScitex’ Powertone Extended Duotone Generator™ allows users to combine any
two inks to create exciting and vibrant two-color separations called Extended Duotones.
Powertone gives designers, prepress shops, and printers the ability to offer their clients
a dynamic, colorful alternative to traditional duotones. Extended Duotones can be used
for printing brochures, newsletters; charity, educational and government printing; the
Yellow Pages, magazines, flyers, packaging, silkscreening, flexographic printing, and
any other two-color print requirement.
Powertone™ separations add incredible value to any two-color print using conventional
inks and printing methods.
Powertone separations require some special attention as they travel through the
workflow. This manual will guide you through the steps needed to produce Powertone
separations of the highest quality. You must have Powertone installed in the Plugins/Import-Export folder of Adobe Photoshop and a working knowledge of the standard
page layout programs in order to generate and output Powertone separations.
System Requirements:
Mac:
PowerPC
MacOS 8.1 or greater
Photoshop 5.02 or greater
Windows:
Pentium-class processor
Windows 9x/NT/2000
Photoshop 5.02 or greater

Quick Reference
The following section is a quick reference guide to using Powertone. More in-depth
information is available in the remainder of this User Manual, or on our website.
1. Quit out of Photoshop (if necessary) and place the Powertone plug-in into the
Photoshop/Plug-ins/Import-Export folder. Windows users should also place the
‘Powertone Automate.8li’ plug-in into Plug-ins/Automate.
2. Restart Photoshop and open an RGB or CMYK original image. Go to the File/Export
menu and select Powertone. Windows users should use File/Automate/Powertone
(Auto-open). Register the software or click ‘Demo’. The Powertone interface will
appear. There is a preview of the original image on the left and a preview of the
Powertone separation on the right.
3. Select the ink set you wish to use from the pulldown ink selection menu. To quickly
generate separations for custom color combinations, use the pre-set ink combination
that is closest to the colors you will print with. If you want to use custom colors, refer
to the ‘Custom Ink Selection’ sidebar on page 3.
4. Click the ‘Save’ button on the interface. The Mac or Windows file browser will
appear. Name your file and choose where it should be saved. Mac users should
make sure the 'MDCS' radio button and the 'Auto-Open' checkbox are both selected;
Windows users should make sure ‘Desktop Color Separation DCS 2.0 (*.EPS)’ is
selected from the drop-down menu. Once you hit 'Save', Powertone will process the
separation and automatically re-open the image in Photoshop.
5. Once the separation has re-opened in Photoshop you can manipulate the image
using the Photoshop toolset. REGARDLESS OF IF YOU HAVE MADE CHANGES
OR NOT, DO A 'SAVE-AS’ AND SELECT ‘PHOTOSHOP DCS 2.0’ AS THE FILE
FORMAT (it should be the default selection).
6. In the ‘DCS 2.0 Format’ dialog that follows, Windows users should select ‘TIFF (8
bits/pixel)’, while Mac users should select ‘Macintosh (8 bits/pixel)’ from the ‘Preview’
drop-down menu. Next, both should select ‘Multiple File with Color Composite (72
pixel/inch)’ from the ‘DCS’ drop-down menu, then click ‘OK’. This saves out three
files, including a lo-res header for placement in your page-layout application and two
linked hi-res plates (these should always be kept in the same folder as the lo-res
header to keep the links established).
7. Open your page layout application (QuarkXPress, PageMaker, or InDesign) and
place the EPS header file. The colors selected in Powertone will be brought into the
color palette and can be used to assign color to text and graphical elements. When
printing separations, select the two colors brought into the color palette and print
them. You’ve just output your first Powertone separation!

Installation
To install Powertone, place the plug-in files in the folders shown in parentheses below
(quit Photoshop first if necessary).
Mac:
Powertone 1.5.4 (Place in: Plug-ins/Import-Export)
Windows:
Powertone.8be (Place in: Plug-ins/Import-Export)
Powertone Automate.8li (Place in: Plug-ins/Automate)
Restart Photoshop and open a color image. On a Mac, Powertone is accessed through
the ‘File/Export’ pulldown menu in Photoshop. It is accessed through File/Automate on a
PC. The first time you use the plug-in, you will be greeted by the End-User License
Agreement. By clicking on the ‘Accept’ button, you are agreeing to all the terms and
conditions contained in the Agreement. Click the Decline button to exit the software
without installing.
Page 4
After you accept the End-User License Agreement, you will be prompted for a user
name and serial number. Your serial number is on the invoice that was issued with your
purchase. After entering your name and serial number, press the register button. To use
Powertone in demonstration mode, click the Demo button.

Using Powertone
Although Powertone is simple to use, working with spot colors can get tricky. Please
take the time to read this manual before calling for technical support. Most questions we
receive are answered in this manual. The following section describes how to use
Powertone once the plug-in has been properly installed and registered.
Step #1. Image Preparation - Open a file and make sure you're using a CMYK or RGB
8-bit image.
Step #2. Launching Powertone - Access the File/Export (Windows export from
File/Automate) submenu and select Powertone. The Powertone interface appears,
showing previews of the original image on the left and the Powertone separation on the
right.
Powertone Main Interface

Step #3.
Ink Selection - Select the ink
combination you want from the pulldown ink
selection menu. This is the easiest way to set
up your colors. It is possible, however, to enter
custom color values. See the adjacent sidebar
for more on setting up custom ink combinations.
Color plates can be previewed by clicking the
eyeball checkbox to the left of the ink name.
Clicking them a second time will restore the
two-color preview.
Step #4.
Tweaking Separations - The
‘Spectras’ window shows the regions of color
that appear in the image. They are represented
in the top row of color swatches. Below each
swatch, the respective amounts of the two inks
that will be used to reproduce that color are
represented. The combination of the ink
amounts - or ‘overprint values’ - appear along
the bottom row. Use this dialog box to adjust
the placement of color in your image. For
example, if there is too much red ink going into
an orange area of the image (a common
occurrence with fleshtones), you would lower
the red ink value below the orange swatch. Use
this method to achieve a good color balance
before saving the image. The black (K), grey,
and white (W) swatches on the right hand side
of the window allow the user to set the levels for
these colors. Black is usually achieved by
setting both inks to 100%, unless you are using
black itself. The grey ‘Overprint’ swatch should
be adjusted to match the grey swatch in the top
row. Do this by adjusting the values of the two
inks accordingly. Adjusting the grey value can
help to eliminate color casts and achieve
neutrality in an image. The white setting is
typically 0% for both inks. If you have created a
custom ink set, click on the ‘Auto-Wave’ button.
Powertone will automatically generate settings
for your inks. You can then fine-tune them until
the preview is acceptable.
Sidebar: Custom Ink Selection
1. Before selecting Custom
Colors, save your default ink set
by clicking the ‘Save Inks’ button
on the main interface. This can
be reloaded to restore the inks
that shipped with the software.
2. Pull down the ink selection
menu and select a blank space
(labelled 'undefined' on Mac,
'untitled' on PC).
3. Click the color swatch to the
left of the ink name slot and
select your color from the
Photoshop color picker. Make
note of the ink name and its
exact spelling.
4. Once you have selected the
ink, type its name in the slot to
the right of the colored oval.
Once both inks are selected,
click the Spectras button,
then click Autowave. The
preview will update and can
then be further tweaked using
Spectras. Click the Apply button
to preview the settings without
closing the Spectras dialog box.

Adjusting the Spectras Dialog
Step #5. Saving Separations - Now
that you have tweaked your image
and have it looking good, it’s time to
save it. Click the ‘Save’ button on the
main interface. On a Mac, select the
MDCS 2.0 file format as your file type
by clicking the ‘MDCS’ radio button
below the filename. Windows users
should choose the MDCS file format
by selecting ‘Desktop Color
Separation DCS 2.0 (.EPS)’ from the
pop-up menu. Always use MDCS if
you are outputting to film or plate.
The EPS file format should be used
only for proofing to a CMYK print
device.
Page 8
Step #6. The Auto-Open Feature - Powertone has an auto-open function that
automatically re-opens the Powertone Extended Duotone in Photoshop after it has been
processed. Windows users should use the File/Automate/Powertone (Auto-Open) to
enable this feature. This allows the user to manipulate the image in Photoshop, then
save the separation as a Photoshop DCS 2.0 file as described in Step #7 below.
Step #7. Saving Extended Duotones as Photoshop DCS 2.0 files – AFTER YOU
HAVE EXPORTED THE EXTENDED DUOTONE FROM POWERTONE, YOU MUST
SAVE THE SEPARATION AGAIN FROM WITHIN PHOTOSHOP. Do this by re-opening
the separation in Photoshop and selecting 'Save-As' from the file menu. By default, the
Photoshop DCS 2.0 file format should be selected. Click OK, then select ‘Macintosh (8bits/pixel)’ for Mac users or ‘TIFF (8-bits/pixel)’ for Windows users from the 'Preview'
drop-down menu, and 'Multiple File with Color Composite (72 pixel/inch)' from the 'DCS'
drop-down menu in the subsequent dialog box. The separation can now be placed into
PageMaker or Quark and printed as separations or composite to a color inkjet or laser
printer (for proofing purposes).
Page 9
Outputting Extended Duotones
Outputting Powertone separations from QuarkXPress and Adobe PageMaker is simple.
If you use other page layout applications, make sure they are DCS 2.0 compliant.
Step #1. Placing MDCS Separations - Powertone outputs three files when you select
the MDCS format. One is a low-res EPS header file and the other two are linked hi-res
plates (labeled filename.1 and filename.2). Be sure to keep all three files in the same
folder to maintain the links. Place the header file in QuarkXPress, PageMaker, or
InDesign as you would with a normal image. The Powertone colors will appear in the
document’s color palette and can be used to assign color to text and graphics.
Step #2. Printing MDCS Separations - Once your document is completed, select ‘Print’
from the ‘File’ menu in your page layout application. The two colors assigned in
Powertone appear in the list of colors available to print as separations. Print these and
you are done.
Page 10
OUTPUTTING FROM NON-DCS 2.0 APPLICATIONS
While not recommended, it is possible to output separations as CMYK.eps files. Do this
by selecting ‘EPS’ when outputting from Powertone. Then place the image in your page
layout application and print two of the four channels. The values for the channels you
print must be 100% in Powertone, with nothing in the corresponding channel of the other
color. This might change your colors, but it ensures that the proper values are imaged to
the appropriate plate, without doubling up (i.e. blue and red both have magenta
properties, so it is necessary to change the magenta value of the blue color to zero and
the magenta value of the red color to 100%).

Troubleshooting
Below are some of the common problems experienced when working with a spot color
workflow. If you have questions not answered below, please refer to the FAQs on our
website or submit your inquiry to our online technical support.
Note #1: Clipping Paths
Powertone Version 1.5 does not support clipping paths. If you have a clipping path in
your original image, follow these steps:
a. Open the original image with the clipping path
b. Open the Powertone DCS 2.0 file
c. Select the clipping path from the Paths palette of the original
d. Drag and drop the path from the original into the image area of the
Powertone separation
Note #2: Printing DCS 2.0 Separations to a Composite CMYK Printer
The DCS 2.0 files output by Powertone can be opened by Photoshop 5.0, but they must
be resaved in order to be printed to a composite CMYK printer (for proofing purposes).
Follow these steps:
1. Open the DCS 2.0 file that was output by Powertone in Photoshop.
2. Select ‘Save As’, then select DCS 2.0 as the format and click ‘OK’.
3. Select the 'Macintosh 8-bits/pixel' or 'TIFF 8-bits/pixel', ‘Multiple File With Color
Composite’, and ‘Binary’ encoding, then click ‘OK’. The file can now be placed
into your page layout application for output to film, plate, or a CMYK printer
(inkjet/laser).
Note #3: Accessing the Photoshop Color Picker
Ink Names - Using custom spot colors in Powertone is easy, although you must type the
ink name into the Powertone interface after you have selected it from the Photoshop
color picker (case sensitive).
Note #4: Preview Problems
Be sure to upgrade your copy of Photoshop to the most recent version to avoid
problems with the preview display in the Powertone interface. The update is available
from Adobe at the following URLs:
http://www.adobe.com/supportservice/custsupport/LIBRARY/5302.htm
Note #5: Code Fragment Manager Error
If you are using Mac OS 8.0 or lower, you will have to download and install the
Appearance Manager Control Panel and Extension (455K), which was issued by Apple
as a patch to the ‘Code Fragment Manager’ error. The error occurs with newer software
(like Powertone) that is optimized for the Appearance Manager which appears in Mac
Page 12
OS 8.1 or greater. The patch is available in the Download Powertone section of our
website.
Note #6: Error Message
In some versions of Windows, using the File/Automate/Powertone (Auto Open) function
will result in a "Photoshop Channelports Suite for Plug-ins is Unavailable" error. In this
event, simply use the File/Export/Powertone function and re-open the resultant file
manually.
