Small ‘slice’ artifacts in screening when Set Halftone Phase for each Page is selected


Product		All versions of Kodak Prinergy Evo

Error		In high-resolution output, small slices that do not line up correctly within images appear in screens or dots within AM screens. This can occur in either dimension.

Symptoms		AM screens that appear to be interrupted or restarted within images

Cause		This is related to the Set Halftone Phase for each Page check box in the Calibration & Screening section for 1-bit output. The Adobe CPSI RIP contains a bug that sometimes incorrectly interprets tiles within an image as the beginning of a new page. The result is that the RIP restarts the halftone phase in the middle of an image, creating the appearance of a slice in the image screening.

Solution		Clearing the Set Halftone Phase for each Page check box removes the artifact.
