The production of the reverse effect of printing, reverse UV printing, how to make this effect

Reverse UV Printing Effect:

1. Print color first, then print white, and then turn over to see, this is mirror printing;

2. Print the color pattern on the back of the material, and then print the white paving, so that it will not transmit light and the color effect is better.

Water-based ink cannot be printed, and UV printing has a reverse effect.

Now our water-based reverse varnish can do it.

Water-based reverse can be done by connecting the printing machine with ink fountain bottom oil + water-based face oil. The effect is dumb where there is a base oil, and bright where there is no bottom oil.

It can do a variety of texture design without increasing the cost and high production efficiency. Eco-friendly and easy to use!

Partial UV varnishing is a kind of surface finishing technology for printed matter. It is named because it uses UV varnish with high brightness, transparency and abrasion resistance to selectively polish the printing**. While highlighting the theme of the layout, it also improves the surface decoration effect of the print.

Local UV is mainly used in the post-press decoration of book covers and packaging products, so as to achieve the purpose of making the printed product icing on the cake. At present, the common local UV effects are: local brightness, local matting, local frosting, local colorful local refraction, local wrinkles and local ice flowers.

Partial UV can be applied either after lamination or directly on the printed matter, but in order to highlight the effect of partial varnishing. Generally, it is carried out after the lamination of printed matter, and most of them are covered with matte film, accounting for about 80% of local UV varnishing products. The biggest difference between local glazing and solid glazing is that one is that one needs to make a printing plate, and the other is that there are certain registration requirements for glazing equipment.

There are three major elements of local UV varnishing, namely glazing plate, equipment registration and curing equipment. In order to ensure that the local UV glazing part is consistent with the printed ** size, the photosensitive imaging method should be used when making the glazing plate.

Questioner commentsThank you!

Reverse UV is our common frosting effect, which is actually the result of the reaction of two media after mixing. Reverse UV is UV varnish, which is mainly used for anti-counterfeiting, and can also have an aesthetic effect. It is also called mutual exclusion oil to replace the previous silk screen scrub oil to improve efficiency.

The face oil and base oil are exposed to UV light to produce a matte effect.

It is a printing process now, called reverse glazing, but only UV printing machine can do this effect, the particles are more delicate than frosting, and the effect of UV is similar to that of the later stage.

In Europe and the United States, printing manufacturers not only use the co-curing process to print the same quality as the traditional UV ink, but also do not meet the high-gloss mirror effect or transparent effect it only has, and further improve this process to achieve higher printing contrast. For this reason, an initial version called the "reverse glazing process" was developed, but at that time, it was not really implemented due to some minor problems that could not be solved, such as adhesion. After several years of refinement, the process has matured.

The following describes the local glazing process using this technology. Pro-cure is the opposite of traditional local glazing. In the past, no matter what kind of glazing method (flexographic printing, screen printing or gravure printing) was used for local glazing, the last glazing process must use local glazing printing to achieve a high contrast effect of local **, therefore, the overprint accuracy of glazing and printing has become the key to the glazing process.

The reverse glazing process breaks through the above laws and solves the registration problem, and the process flow is as follows.

Conventional printing must be completed before glazing, and it must be confirmed that the ink has been thoroughly dried or cured; Then, the non-high-gloss parts of the design draft are printed with transparent reverse ink in offset printing by connecting or offline. The line is then connected, and UV varnish is applied to the printing surface in a solid plate and cured.

At this time, the cohesive reaction between the varnish and the reverse upward light ink contact area forms a small granular ink film, and the reverse upward light area forms a mirror surface.

Obviously, with the reverse glazing process, there will be both high-gloss and non-high-gloss effects on the same print.

Yes, reverse UV is also UV frosting, but the saying is different, Shenzhen Xutian Printing has done a relatively successful job in UV frosted printing, which is a leader in the industry.

Reverse is reverse, scrub is scrub, reverse oil is reverse, scrub oil is used for scrub, are two different processes.

Jiadetong printer will answer for you: the current advertising can be realized if the UV flatbed printer is used, and you can also ask more.

Chongqing Hongjin Printing can produce, how much do you have, in **.

The effect of laminating silk screen printing is almost the same, saving two processes, and printing it down with a printing machine at one time, the disadvantage is that the wear resistance is not good, and it is easy to fade.
