I have a piece of copy (art) - it is screened (a halftone) at 133lpi. I need to make a positive / negative from it - at 65lpi (size not critical) If I shoot the art in the camera (at 133lpi) using a contact screen at 65lpi. I will have a moire pattern from the two interrupting patterns. Question: => How do I re-screen an existing halftone into a new one at a different lpi without getting moire?? or => How can I change a halftone so it is reproduced in the camera like continous tone?? You can only use conventional vertical / horizontal camera and contact screen for this reproduction job. Your help is much appreciated.
