Title:
PRINTING PLATE RECORDING DEVICE, PRINTING DEVICE EQUIPPED WITH PRINTING PLATE RECORDING DEVICE AND IMAGE DATA ORIGINATION DEVICE USED FOR PRINTING PLATE RECORDING DEVICE
Document Type and Number:
Japanese Patent JP3670564
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a printing plate recording device which makes up a printing plate capable of preventing ink from being excessively emulsified during printing, a printing device equipped with the printing plate recording device and an image data origination device to be used for the printing plate recording device.
SOLUTION: An ink supply arithmetic part 24 performs a cumulative arithmetic processing of image data to each of ink colors based on PPF data D2 and calculates the ink supply X per each of a plurality of regions in the printing crosswise direction. A small ink supply region decision part 25 decides whether a small ink supply region where the ink supply X is below a specified level exists. An ink consumption region data storage part 26 previously stores a plurality of sets of ink consumption region data D3 and the amount of ink to be consumed by the ink consumption region as an additional ink supply XD. A superposing part 28 superposes the ink consumption region data D3 to binary image data D1. Thus it is possible to form the ink consumption region for minimum ink consumption level on the printing plate.
