Rotogravure form imaging method for publication printing, involves providing cups of different dimensions to image rotogravure form, and assembling image data provided for imaging of form from image tiles

摘要

The method involves providing rhomboid shape central cups (1, 2a, 2b) of different dimensions to image a rotogravure form to achieve different tone values or print densities by engraving. Image data for imaging the rotogravure form is assembled from image tiles (3, 4) e.g. polygonal image tiles, by a controller, where some of the image tiles contain a partial cup formed by a portion of adjacent central cups. The partial cup is connected with the central cups by an ink channel (8) in an ink-conducting manner. An independent claim is also included for a system for imaging of a rotogravure form.
