ABSTRACT:
A data creating device for printing plates optimizes image data for use in forming printing plates using a printing press having a feed reel for feeding printing film onto a circumference of a plate cylinder from a circumference recess formed in the plate cylinder, a rewind reel for rewinding the printing film fed from the feed reel so as to draw the printing film from the circumference of the plate cylinder, and an image forming device for forming an image on the printing film placed on the circumference of the plate cylinder. The data creating device detects a maximum position of the image data in a plate transfer direction. The data creating device deletes data downstream of the maximum position in the plate transfer direction, thereby creating optimized image data. The data creating device stores the optimized image data in a memory to be used in forming the printing plate.
