Mixed ink characteristics

Compared with ordinary ink, mixed ink has many advantages.

Mixed ink printing combines the features of UV-curing and traditional offset materials to maximize UV ​​ink-cured characteristics. The key to this process is UV-curing technology, where high-energy UV lamps instantaneously cure and dry mixed inks between the press and the glazing unit. This instant cure dramatically reduces energy consumption, reduces production, storage, and disposal costs and increases production efficiency.

Mixed inks do not require the use of special ink rollers, blankets, and fountain solutions for UV inks. In this way, printers use mixed inks when they need to be glazing on line, printing them with ordinary inks without glazing. In the case of mixed inks and ordinary inks, different ink rollers and blankets may have some effects when used with mixed inks.

Printed with mixed inks, the gloss after UV coating will not fade, it is especially suitable for the printing of high hiding power.

The printing performance of the mixed ink on the printing press is also like ordinary ink. The ink ink balance of UV ink is generally more difficult to control, but the mixed ink is similar to ordinary ink, and it is not difficult to control the ink balance. The printing characteristics of UV inks, such as dot gain, overprinting, and printing contrast, are inferior to those of ordinary inks, and mixed inks are similar to ordinary inks. In addition, since the UV-curing material in the mixed ink is not dried before the UV lamp is irradiated, the mixed ink is always flowing on the printing machine, so the printing failure is not caused by the skinning on the ink roller like the ordinary ink.

Printing with a mixture of inks allows for on-line UV coating without the use of water-based varnishes because of the instant drying. The print quality is no worse than ordinary offset printing inks.

Mixed inks have a wide range of adaptation and low investment. For printers that already have UV technology, they only need to buy a mixture of inks. For printers that do not use UV technology, they need only invest in UV curing equipment and UV lamps in addition to purchasing mixed inks.

Application of mixed ink

In addition to being used primarily for paper printing, hybrid inks can also be used in non-absorbent printing materials such as plastics, aluminum foil, and metal paper. It has good adhesion to plastics. Utilize UV ​​curing technology to solve the ink drying problem of non-absorbent printing materials. The mixed ink prints clear dots and improves the quality of offset printing.

Mixed inks can be used on sheetfed presses as well as on narrow web presses. More and more mixed inks are now used to print products that require good gloss, such as photo albums, posters, cards, folding cartons, pharmaceuticals, and cosmetic packaging boxes.
