Using Over Print and Trapping commands
A workflow with graphic software
The PhotoPRINT Server can only accept an Over Print and trapping
commands that were made on spot colors.
Therefore, you must make the colors that you are using in "Illustrator" or
"Freehand", spot colors.
If you are using a pantone or process colors, you have to change their
names to “Cyan”, “Magenta”, “Yellow” and “Process Black”.
The name "Black" is a reserved name, so if you want to name a color "black" and
make it spot, you can only name it "Process Black".
You don't have to make all the colors you are working with spot colors. It is
only necessary for the ones that you are going to make Over Print. The
other colors can stay as process colors.
As an example, make a regular graphic art and use any process colors you
need. When you finished, choose only the elements you want to be over
print, and make them spot.
Naturally, if the original color is black (which is most likely), you would
want to call it "Process Black". In the closing menu (PostScript), you will
have five colors: "cyan", "magenta", "“yellow", "black" and "Process Black".
Once you have carried out the RIP process, you will have four separations -
CMYK, and after examination, you will see that the "Process Black"
separation has joined itself to the "black" separation, however, it retains
the Over Print properties.
