I have tried unsuccessfully to export colour separations from Illustrator (CS5.1 MacOSX). I need the separations in an editable file format, but it seems like I am only able to print separations.
I have tried to print to a file with Output set to host-based separations but even that seems to be impossible. I get an error message "The save as PDF options in the Printer dialog are not supported".
The software is clever enough to do the separations, but somehow it can only print, not export them. Is there any additional software that would pose as a printer but instead of printing would create a file?
Why can't you simply print seps to a postscript file.
Drag the resulting postscript file (.ps) to Acrobat Pro, which will convert it to a PDF.
The PDF will ahve a page for each plate.
Save the PDF.
Open the PDF with Illustrator and pick a page for the plate you want.
Actually, that is just what I finally did.
Previously I had tried printing to a PostScript file and opening the .ps file in Illustrator, but that gave me only the first page without any possibility to choose the page. That experience made me think that .ps files are useless for this purpose. Only yesterday after googling the error message I learned that I have to distill the ps into pdf before opening it in Illustrator.
