Present, the main and screen printing and offset printing flexo combination or combinations. For example, high precision rotary printing units with screen printing machine flexo combination printing, screen printing can be stacked using a relatively thick layer of ink has excellent hiding power, can be characterized by coarse print, re-use flexo their printing speed, high-definition advantage of it in the package printing market, and gradually occupy an important position. Another example cylinder screen printing machine, the general rate of 4,000 / hour, the use of advanced positioning methods may be offset combinations, high fine halftone screen printing offset printing, and special decoration results.
Screen Printing in combination printing, mainly undertake the following functions: (1) enhance the attractiveness of products. Requires the use of space through effective design, use very dark or light color ink, etc.; (2) produced a more hostile environment in the use of the label.

L, UV curing ink Ultraviolet (uv) inks major features include: (1) Instant drying. Printed materials by UV lamp irradiation (300 ~ 400) instant curing, the paper can be folded right away and will not rub dirty. Heat oven curing ink about 30M long power 220kw. The UV curing device for the 2M length, power 64kw, significant savings in plant and energy consumption, improve productivity; (2) non-toxic. uv ink does not contain solvents, during the curing process, apart from a small amount of easy to rule out the possibility of ozone, the pollutants will not distribute any; (3) high performance ink film. In a variety of solid substrate on the good, the ink film integrity, program of resistance, abrasion resistance, acid and alkali resistance, the performance of ethanol were much higher than normal ink.
UV Ink imitating metal etching Uv printing, also known as imitation metal etching or sand matte surface printing, it is the shiny metallic mirror substrates (such as gold and silver cardboard) printed on the layer of rugged translucent ink, and then through the UV curing can produce effects similar to etching, or grinding, three-dimensional sense of strong, high grade trends used in packaging products can be fully shown, has been , wine standard, cosmetics, health products, such extensive use of color printing industry.
