I provided a customer a pdf file created in Illy, with spot colors and spot halftones.
He showed me that the solid spot colors showed up, but the halftone areas did not. I think he was printing the vector seps out of Quickseps or some other sep program. So not sure how that worked out. I don't think he even needed to print to film by going thu one of those sep programs.
I had several low percentages of colors overtop one another that were to blend to create a grey. They didn't come out on his seps so I wanted to see if there is some method you must do first to assure the seps to print out with halftone dots.
I send him another pdf file and assigned those halftone areas to multiply but no go.
