The significance of inkjet CTP As a plate-making process, inkjet CTP system back in the 70's emerged. In 1978, the German Hurst (Hoechsh) company for the inkjet plate-making technology, developed patented (patent No. 2,806,802 German Patent No.). The patent after surface roughening and anodic oxidation of aluminum substrate, water based or oil-based ink in the ink-jet printing device for ink jet printing, conducted at 120 heat treatment, then a blank portion of hydrophilic processed on the machine can be printed.
Inkjet CTP technology can do with ordinary PS edition version of the base, light-sensitive coating can be decomposed or type of light photopolymerization type, but also directly by the roughness, porous anodic aluminum oxide obtained by imaging print edition , the ink can be water-soluble ink, Plastisol ink , UV curing inks. In general PS edition print by printing down, after developing can be printed on the machine; the bare version (that only do rough and oxidation treatment, which is not version-based coating photosensitive coating) on the print, the only cure can be printed directly on the machine, it is not wet-type plates. Inkjet CTP without any pollution to the environment, known as green products. As Polychrome CEO Bob said: "From a long-term development perspective, the inkjet printing plate has great potential because it is a truly green plate."
From the content, the inkjet CTP plate system is used in the PS version of regular or light-sensitive layer coating the blank version of the base, the cost is low, it should be with the PS version of the price equal to or even cheaper . CTP's advantage is eliminating the need for film, save money, reduce environmental pollution, inkjet CTP system is in the original CTP technology to build on.
Status Inkjet CTP Inkjet CTP plate of the plate-making process is generally divided into two types: indirect inkjet CTP plate making and bare Edition inkjet CTP plate. Indirect inkjet CTP plate making process is dedicated imaging ink inkjet plate-making machine by spraying the plate graphic form, such image ink and traditional version of the emulsion layer of aluminum a chemical reaction with the aluminum version of the solid; Naked Science inkjet CTP plate making process is directly imaging the surface after spraying the solution Coarsening and anodized aluminum version of the non-coated, and then by drying, surface treatment imaging solution to fixing on the aluminum version.
Present, the more respect in the inkjet CTP is America's leading corporations and Denmark JetPlateSystems Glunz & Jensen Inc., which both companies claim their CTP system, has reached 175 lines / inch the image quality.
U.S. JetPlateSystems off JetPlate4800 latest launched and four open JetPlate7800CTP system. JetPlate system is an indirect inkjet CTP plate making process, first known as "liquid light" PlateMarker dedicated platesetter imaging by imaging ink spray in the plate to form images, special ink that can be used for image with the traditional aluminum version of the emulsion layer of a chemical reaction and solid with the aluminum version, and then by manually developing machine on the aluminum version of the entry platform and the conveyor belt, the transmission system with a plate into the imaging machine, and in turn complete the following processing steps: first use of liquid and the emulsion layer of hot air to accelerate the reaction, rapid fixation of ink on the plate; then by the developer solution and the rotating brush on the plate for imaging, except for some non-graphic emulsion; in the wash tank on plates were washed to remove residual developer solution on the plate; Finally, plates were baked, get dry, durable plates, ready to print on the machine.
As a world-class leading supplier of CTP imaging machine, Glunz & Jensen's latest launch PlateWriter2000CTP inkjet system. PlateWriter system uses the bare version of inkjet CTP plate making process, directly to the imaging solution (LiquidDot) after spraying the surface roughened and anodized aluminum non-coated version, the imaging plate after plate manually into the address drying device, so that imaging solution to fixing the surface of the plate by plate handling devices built on plastic plates coated platform to protect the plastic protection plate for printing on the machine ready.
