There are many paper packaging and printing processes. The following are several commonly used printing processes:
1. Bronzing process:
The performance of the bronzing process is to heat the required bronzing or silver stamping pattern into a convex version, and then place the required color of aluminum foil paper on the printed object, pressure, so that the aluminum foil attached to the printed object.
Tip: there are many kinds of bronzing paper materials, including gold, silver, laser gold, laser silver, black, red, green and so on.
2. laminating process:
Laminating process is a surface processing process after printing, refers to the use of laminating machine on the surface of a layer of transparent plastic film and the formation of a product processing technology.
Tip: after coated printing, the surface will be more smooth, bright, stain resistance, water resistance, wear resistance.
3. concave and convex embossing process:
The process is the use of relief printing press greater pressure, has been printed on the semi-finished part of the pattern or text rolled into a concave and convex, with three-dimensional graphics.
Note: concave and convex embossing process is mainly used for printing and paper container after processing, in addition to packaging cartons, but also applied to bottle labels, trademarks and book binding, calendar, greeting cards and other products in the printing.
4. UV anti-metal etching printing process:
UV anti-metal etching printing, also known as matte or sand printing, is in a metallic mirror luster substrate (such as gold, silver card) printed on a layer of uneven translucent ink, after ultraviolet light (UV) curing, resulting in similar bright metal surface after etching or grinding effect.
Note: UV anti metal etching ink can produce suede and matt effect, can make the print appears soft and solemn, elegant and luxurious.
In addition to several printing processes introduced above, paper packaging printing process also includes refraction, die cutting indentation, hydrothermal transfer printing, drip plastic, ice, scraping silver and other printing processes.
