Abstract
The present invention relates to an ink jet plate-making offset plate material with hydrophylic property. It includes printing plate material whose surface has hydrophylic layer, said hydrophylic layer has good affinity with printing ink, so that the ink spot jetted on the surface of hydrophylic layer does not overflow toward periphery, so that its picture and character quality are good, besides, the hydrophylic layer also can effectively prevent the printing plate material from being oxidated in the course of storage.
Description
Technical field
The present invention relates to a kind of printing plate, especially a kind of offset press is with having hydrophilic ink-jetting plate-making offset plate material.
Background technology
The CTP system that tradition colored printing plate-making and latest developments are got up all designs based on amplitude modulation site theory, and equipment is expensive, complex process, cost height, and the digital specimen page and the print sample of CTP system are difficult to be transferred to consistent.Print theoretical and the present invention is based on frequency-modulation halftone dot, with computer type-setting document has been pieced together big version by printing bookbinding folding hand, accomplished fluently digital specimen page, after the approval of client's signed-off sample with the large format color inkjet printer, the color separation of big version file is printed on the hydrophily aluminium plate, can directly goes up press printing.Because printing digital specimen page is frequency-modulation halftone dot, the color separation file that is printed on the aluminium plate is original file of playing digital sample, both can never go wrong, and color separation to be printed on the aluminium plate also be frequency-modulation halftone dot, print color is easy to consistent with the digital specimen page of before beating.Previous because ink-jet printer resolution ratio is low, speed is slow, print quality is low, is not suitable for doing the plate-making of high-grade color printing, thus limited the development that the frequency-modulation halftone dot colored printing is made a plate.Color type wide format ink jet printers such as Seiko Epson Corporation's release recently 7500,9500,9600,10000CF, printing precision reaches as high as 2880dpi, printing precision reaches the precision of existing laser photocomposing machine 175 lines/2540dpi fully, raising along with the precision and the speed of ink-jet printer, ink-jetting forme-producing system becomes the main flow of plate-making industry the most at last because equipment price is low, the plate-making cost is low, technology is simple.No matter be traditional based on amplitude modulation site theory colored printing plate-making or present colored printing forme-producing system based on frequency-modulation halftone dot printing theory in employed version base be generally aluminium sheet, this aluminium sheet behind ink jet, easily take place to around overflow, influence the picture and text quality; Aluminium sheet easily oxidation in the preservation process in addition, the life-span is short.
Summary of the invention
The purpose of this invention is to provide and a kind ofly be difficult for the overflow printing China ink, and long ink-jetting plate-making offset plate material of life-span.
Ink-jetting plate-making offset plate material of the present invention comprises the plate of undertaking the printing of.The wherein said plate surface of undertaking the printing of is provided with hydrophilic layer.
Ink-jetting plate-making offset plate material of the present invention, wherein said hydrophilic layer comprise by weight 1 part of hydrophilic macromolecular compounds and 4～20 parts non-ionic surface active agent.
Ink-jetting plate-making offset plate material of the present invention, the ratio of wherein said hydrophilic macromolecular compounds and non-ionic surface active agent are 1: (8～10).
Ink-jetting plate-making offset plate material of the present invention, wherein said hydrophilic macromolecular compounds are one or more in gum arabic, carboxy methyl cellulose, polyvinyl acetate emulsion, polyvinyl alcohol or the gelatin.
Ink-jetting plate-making offset plate material of the present invention, wherein said non-ionic surface active agent are polyoxy alkene fatty alcohol ether.
Ink-jetting plate-making offset plate material of the present invention, wherein said non-ionic surface active agent are the mixture of AEO and APES.
Ink-jetting plate-making offset plate material of the present invention, the wherein said plate of undertaking the printing of are the thick aluminium sheets of 0.15～0.60mm.
The advantage and the good effect of ink-jetting plate-making offset plate material of the present invention are: owing to be provided with hydrophilic layer on the plate surface of undertaking the printing of, on the one hand, hydrophilic layer and stamping ink have affinity, thus the ink dot that is sprayed onto the hydrophilic layer surface not can to around overflow, so the picture and text quality is good; The hydrophilic layer plate oxidation in the preservation process that can effectively prevent to undertake the printing of on the other hand, thereby the ink-jetting plate-making offset plate material life-span of the present invention is long.
