Screening for Illustrator
1. Introduction
The current version of DeskPack for Adobe Illustrator can only handle 1 specific Ink parameter set
per separation. To be able to apply specific DGC strategies, or to be able to have multiple lineatures
and/or multiple angles or screening into a single separation this concept needs to be extended. The
usage of these mixtures is very common in Packaging jobs. In addition to the ability to have different
DGC strategies applied to different parts of a job, in specific cases it is necessary to exclude certain
objects from DGC e.g. compensation might be necessary in specific halftone areas, but not in flat
logo tints, since it might damage the integrity of the corporate color. The FlexRip has support for
such concepts in case properly tagged objects are provided to the Rip. The EPF concept of tagging
could be extended with ink property tagging.

2. Screening for Illustrator overview
InkManager allows you to set the technical parameters of the inks. Thanks to InkManager every ink
can have its own type, ruling, angle and dotshape set. For some objects Screening for Illustrator
allows you to make exceptions to these inks parameters.

3. Screening for Illustrator workflow
The Screening for Illustrator workflow :
1. InkManager shows you the actual settings of all inks.
2. Select the objects of which you want to change the ink settings.
3. On the menu select “Window > Esko > Screening”.
The 'Change Ink Options' dialog appears.
The dialog shows you all inks that are used in the selected objects including their ruling, angle
and dotshape. You can change the settings of these inks. You can either change one specific ink
or set the value to all inks by using the “Apply To All” edit boxes. If several technical parameters of
one ink correspond to the selection, the appropriate edits in the “Change Ink Options” are empty.
4. After applying the inks, the specific ink’s parameters are set to the object.
5. The variable inks are shown in the InkManager table.

Note:
Currently we do not have the possibility to apply DGCs per object or region.
The best workaround would indeed be the (slight) adjustment of angles of a screen. This method
is based on the fact that only a limited set of angles of screens is available in our FlexRip and that
a "map to nearest" rule will be applied to choose the screen.This way 2 screens with a very small
difference in angle, will eventually map to the same screen but with different DGCs applied to them.
Job :
object A with screen A and e.g. angle of 7.5 object B with screen A and e.g. angle of 8.5
Screens on rip:
screen A with e.g. angles of 0, 7.5, 15,... DGC strategy (*.icpro): Angle of 7.5 --> dgc_1.dgc Angle
of 8.5 --> dgc_2.dgc
What will happen on the rip?
1. There is a DGC selection (based on the *.icpro file that was sent along): screen A with angle 7.5
will get dgc_1.dgc applied to it, screen A with angle 8.5 will get dgc_2.dgc applied to it 2. A screen will be chosen (and the DGC will be kept) screen A with angle 7.5 will stay screen A with
angle 7.5 (and dgc_1.dgc) screen A with angle 8.5 will "jump" to the nearest available angle, thus
becomes screen A with angle 7.5 (and dgc_2.dgc !)
Result : Object A and object B will both be ripped with screen A and angle 7.5, but with different
DGC's.

4. Added features of the InkManager table
• Each ink can visualize all the technical parameters (ruling, angle, dotshape) it contains. Note that
you are free to enter a name of your own choosing for dotshape
• For each ink, each specific technical parameter can be selected and edited via the InkManager
dialog (by double-clicking the specific ink).
• You can select all the objects that use the specific ink, or specific ink parameters by the 'Select
Art Using Ink' button

5. Export workflow
When exporting to EG Native (both GRS and Normalized PDF file) the additional technical parameters
of ink and objects tagged with these inks are exported as well.
