    摘要: A method of modifying screened image data so that there is no visible seam when the image is printed repeatedly in a circumferential direction, for example using a drum output device. One version applicable to images screened using a supercell includes cutting the image so that the image size in the circumferential direction is an integral number of screen supercells. Another version includes displacing halftone dots in a neighborhood of the seam such that the seam is not visible in a repeated print.

    摘要: Creating one or more printing plate segments includes exposing a printing plate segment with imaging data to form an imaged plate segment, and marking the floor of the printing plate segment or the back of the printing plate segment with one or more registration marks according to marking data. The registration marks can be within the design area defined by the imaging data marked such that the registration marks are not visible on a print made from the imaged plate segment. Printing using positioned and mounted so-marked imaged plate segments produces a print without the registration marks visible on the print. Such plate segments can be unmounted and reused with the registration marks intact.
