Embodiment 1

[0024] The system uses EPSON 7600 inkjet plotter, Founder RIP software, EPSON original quick-drying ink and 0.15 mm thick aluminum base plate treated with electrochemical oxidation and coating method.

[0025] The image is output to the printer according to the color separation of the frequency-modulated hanging network by using Founder’s image-text processing color separation and hanging network RIP software. The printer sprays the ink onto the surface of the aluminum base plate, and after 1 minute of infrared radiation, the printing plate with a resolution of 2880DPI can be obtained. Its dot reproduction rate has reached 98%, fully able to meet the needs of 175LPI high-quality printing.

Embodiment 2

[0027] The system selected is EPSON 7600 inkjet plotter, Founder RIP software, ink prepared according to the patent application of "a nano-pigment ink for inkjet CTP plate making technology" and a coated 0.15 mm thick polycarbonamide base plate .

[0028] The image is output to the printer according to the color separation of the frequency-modulated hanging network by using Founder’s image-text processing color separation and hanging network RIP software. The printer sprays the ink onto the surface of the aluminum base plate, and after 1 minute of infrared radiation, the printing plate with a resolution of 2880DPI can be obtained. Its dot reproduction rate has reached 98%, fully able to meet the needs of 175LPI high-quality printing.

Embodiment 3

[0030] Mix the nano pigment particles (black) of 3% by weight with 5% phenolic resin, 20% ethanol, 2% glycerol, 70% ethylene glycol monoethyl ether, heat to 40 degrees Celsius and stir for 6 hours, and wait for the resin After dissolving and mixing uniformly, filter with a 0.5 micron filter membrane to obtain suitable nano-pigment ink.

Abstract

The invention discloses a CTP direct plate-making method and equipment using the principle of inkjet imaging. Using the principle of inkjet imaging, an inkjet printer is used to spray hydrophilic ink onto the surface of a hydrophilic plate to form a lipophilic information recording area. Photocuring or heat curing stabilizes the printed information on the surface of the printing plate and can be printed on the machine. The method of the invention utilizes the principle of ink-jet imaging, and the loss of information in the plate making process is very small. When the frequency modulation software and the printer parameters are properly matched, 100% loss-free transfer can basically be realized. In addition, this technology can avoid the process of ordinary silver salt plate making and photosensitive or thermal CTP plate making to make a latent image first and then develop it. It saves the film and subsequent development process, and is the most direct CTP technology.

Description

1. Technical field [0001] The invention belongs to the technical field of printing and plate making, and in particular relates to a CTP computer-to-plate making technology method and related equipment utilizing the principle of inkjet imaging. 2. Background technology [0002] Since the Drupa Expo in 1995, the wave of CTP (Computer-to-plate computer-to-plate) has set off in the global printing industry. As the most revolutionary cutting-edge technology in the field of lithographic offset printing technology, CTP technology makes the image-text processing system more open. In the current printing field, digitization and networking have become the basic characteristics and development trends of electronic pre-press digital printing, and CTP technology and its system are the basic prerequisites for digitalization in the printing field. [0003] The so-called CTP technology refers to the direct output of computer typesetting page numbers to the printing plate, after rapid proce...
