I have a customer that we produce negatives on transparency film for t-shirt screen printing. Recently he has asked me to print his halftones using a dot pattern using the postscript driver, is there a way to output an illustrator file to a Xerox DocuColor 250 and produce his dot pattern. Ihave attached two examples one of his current file and one of roughly he wnats the output to look like, I have manipluated the illustrator file to produce the dot pattern and he is suggesting that when I send his original file to the printer it should create the dot pattern, any help is greatly appreicated. thanks
