Analysis of Several New Printing Technologies Worthy of Attention (I)

HYBRID technology application

1. Waterborne Varnish HYBRID Technology

Waterborne varnish HYBRID technology refers to the technology that can show both high gloss and matt gloss when printed on the same print.

The hardware requirements of this technology are relatively high, and the operating technology and application technology are relatively simple:

Substrate must be high gloss paper; printing equipment must be 5+1 or more; use oily matte oil in the last color group through the PS plate for local glazing, then in conjunction with high gloss water varnish on glazing color group Full version of glazing, pay attention to oily matte oil and water-based high-gloss opaque oil is a special varnish, non-plain varnish; by adjusting the coating amount of oily matte oil to control the contrast effect of light and matte;

2.UV Varnish HYBRID Technology

UV Varnish HYBRID technology is the use of UV Varnish for a printing that can produce the following two kinds of printing technology: one: sticking and high light effect; two: matt and high light effect; UV Varnish HYBRID technology requirements for printing hardware Similar to HYBRID technology for waterborne varnish, it needs to be printed on high gloss paper, and printing equipment with 5+1 or more is needed at the same time. The operation is similar, but the drying method is UV curing and drying, and the hardware requirements are higher; the adjustment of dendrite and highlight contrast The effect and the contrast effect of adjusting the matt to high light are all achieved by adjusting the ink amount of the oily UV varnish. Please pay attention to the problem of the drying of the UV varnish. In order to ensure the UV varnish drying, the printing speed can be appropriately reduced. Determined to be dry; at the same time, please pay attention to the effect of sticking and high-gloss sticking effect oily varnish and high-gloss UV varnish, which are special varnish used together; matt varnish and high-gloss matte finish and high-gloss UV Varnish is a special varnish used in conjunction with

2. Suede varnish and metallic varnish

For the characteristics of modern printing, environmental protection and anti-counterfeit effectiveness, based on the water-based gloss oil and added a number of special effects of water-based Varnish, which has a high use value is the water-based suede Varnish and Varnish.

The water-based suede varnish is an effect that the aqueous varnish system exhibits suede during the drying process after coating. The strength of the suede effect is related to the amount of varnish on the varnish, if the ceramic anilox roller is used. Light system, through the adjustment of the number of lines of the anilox roller to achieve the purpose of changing the amount of oil, in order to enhance or weaken the suede effect; water-based metal varnish is the use of water-based coating system after the coating surface after the metal color, There are many kinds of colors, including silver, bright gold, bronze and other colors, the strength of the metal color is mainly related to the amount of light, coating the greater the amount of metal the stronger the effect.
