Introduction to the UV reverse polish process introduction to UV reverse polish

reverse polish ( 赞成 治愈) From the perspective of the local glazing is compared with the traditional. In the past, no matter use what kind of glazing methods ( Flexographic printing, screen printing or gravure) The last line of local glazing, polishing process is bound to use local gloss printing, in order to realize the local images and high contrast effect, therefore, polishing and printing overprint precision becomes the key to polishing process. And reverse glazing technology break the law, make the alignment problem solved.

And reverse glazing technology break the law, make the alignment problem is solved, the process is as follows.

the creation must first complete the regular printing, and determine the printing ink has been completely dry or curing; Then, will design draft on the attachment or offline way Gao Liangguang parts in offset printing on transparent reverse ink; Attachment again, in the full version in the printing surface coated UV light oil and curing.

at this point, the contact area and reverse light oil ink cohesion in response to form a small granular ink film, reverse polish area of mirror surface is formed. Obviously,

with reverse polishing process, the same calendar will exist Gao Liangguang with non Gao Liangguang effect at the same time. Moreover, because the Gao Liangguang part is offset printing, overprint precision, also ensure the precision of part Gao Liangguang graphic.

in the country, the main substrates are absorbing UV printing materials. And in Europe and America region, printing manufacturers not only use in curing process printing with traditional UV ink printing quality, same quality and does not meet their only has a high gloss mirror effect or transparent effect, improved the technology further, in order to achieve a higher printing contrast. Therefore, developed a called 'reverse polishing process' the early version of the but at that time, due to some details failed to solve, such as adhesion, so there is no real implementation. After several years of improvement, this technology has been mature gradually. Conversion table packaging printing knowledge
