In general, we call the special processing methods that use special performance inks, printing methods, and printing on special shapes or special materials as special printing. Special prepress technology is a huge printing press technology group formed by the combination of the latest edge science in the long-term development process. Therefore, the special printing process has five most commonly used processes.
First: The pearlescent printing process refers to the use of pearlescent ink technology. Since the pearlescent ink has the natural luster of mussel beads, the surface smoothness of the substrate is relatively high and the printing effect is the best.
Second: perfume ink printing process, perfume ink is to add perfume directly to the ink, there are flexographic relief printing, and offset printing, the method is relatively simple, the disadvantage is that the fragrance is difficult to preserve for a long time.
Third: Foam printing process, the so-called foam printing refers to the printing method of using microsphere foam ink to print on paper and other printed materials through screen printing, and then heating to form a raised relief-like graphic or braille reading.
Fourth: The decal printing process is generally realized by indirect transfer. The main processes of the decal printing process include plate making, printing, transfer and post-processing.
Fifth: flexographic printing. Because the flexographic printing process has the common features of offset printing, relief printing, and process, it has a wide range of adaptation to the characteristics of the substrate, simple structure, and high precision.
The role of special printing in the post-press processing of product packaging and printing is becoming more and more important. In order to further improve product personalization, in addition to the development and application of new special processes, many manufacturers also incorporate the original processing technology and special inks and special materials. Combined, new special printing technology is formed, which improves the competitiveness of products in the market.
