UV printing a wide range of use, the researchers of its production technology also has a lot of attention and breakthrough. Which by the reverse glazing technology by more people's attention. What is the meaning of reverse glazing technology? I believe that most of the outsiders are not clear.

In the country, UV printing of the main substrates are non-absorbent materials. In Europe and the United States, the printer not only the use of co-curing process and traditional UV ink printing the same quality of print, and does not meet its only high gloss mirror effect or transparency, and further improve the process to achieve Higher printing contrast. To this end, developed an early version called "reverse glazing process", but at that time, because some of the details of the problem failed to solve, such as adhesion, so there is no real implementation. After several years of improvement, uv printing factory manufacturers this process has become more mature. The following describes the use of this technology for the local polishing process.

Pro-Cure is relative to the traditional local glazing. In the past, no matter what kind of glazing method (flexographic printing, screen printing or gravure printing) for local glazing, the last glazing process must use the local glazing printing, in order to achieve the local image of the high contrast effect, Therefore, the polishing and printing overprint accuracy become the key to polishing process.

The reverse glazing process breaks through the above-mentioned law, so that the registration problem is solved, the process is as follows: before the glazing must be completed before the regular printing, and to determine the ink has been completely dry or cured; and then by wire or offline design On the non-high light parts to offset printing transparent reverse ink; then connect to the full version of the way in the printing surface UV varnish and curing.

At this time, the varnish and the reverse contact area of the photoexcitation to produce a small granular ink film, the reverse glazing area is formed mirror.

Obviously, the use of reverse glazing process, the same print will be on both high light and non-high light effect. Moreover, because the non-high light parts are offset, overprint accurate, but also to ensure the high light part of the graphic accuracy.

The fundamental printing is to better and faster dissemination of information, and UV printing reverse glazing technology is on this basis to complete a better printing technology, to achieve a higher printing effect, to provide consumers with A better product experience.
