s3, the environment-friendly printing ink comprises the following components: 30-40 parts of fluorescent material, 20-30 parts of methyl hexadecanoate, 15-17 parts of modified starch fiber solution, 20-22 parts of phenolic resin, 3-5 parts of rosin ester, 2-6 parts of magnetic powder, 20-25 parts of nano color paste, 5-7 parts of isophorone, 5-7 parts of cyclohexanone, 10-12 parts of branched polyester resin, 10-20 parts of nano titanium dioxide and 10-12 parts of gel;
s9, at least three of gloss varnish, matte varnish, pearlescent varnish and UV (ultraviolet) glazing are adopted;
gloss oil is a type of gloss oil which is very commonly used, and the gloss oil is adopted to improve the expression strength of pictures;
the matte gloss oil is a gloss-free glazing mode and is suitable for being applied to paper board text pages;
the pearlescent gloss oil is used for conveniently showing a fanciful color effect under the emission of light, reducing the effect of light reflection and enhancing the viewing feedback of the graph and the character under the light;
the UV glossing is a resin added with a light curing agent, the smearing mode is similar to the printing ink, and the UV is dried by adopting an ultraviolet curing mode, so that the UV glossing is safer and more environment-friendly than other glossing technologies, and has the advantages of high drying speed, no limitation on the type of printing stock, low energy consumption, energy saving, good quality, friction resistance, corrosion resistance and the like.
The polishing oil process has two main modes: printing coating processing and special polishing coating machining. The printing coating process is to apply varnish by a printer apparatus, and in practice, varnish is used as a special ink for printing. Specifically, in the printing process, gloss oil is transferred to a printing plate through an ink conveying system and is covered on ink which is not dried, and the gloss oil and the ink are absorbed by paper fibers; the special coating processing of the glazing coater is that the coating operation is carried out by using coater equipment after the printing ink of the printed matter is dried, thereby reducing the absorption of paper to the varnish coating and maintaining the glossiness of the varnish. The ink absorbing capacity of the printing stock is an important influencing factor for ensuring the gloss effect, so that the paper subjected to the coating treatment is preferably selected;
the bulge is at least one of colored bulge and colorless bulge, and the press concave is at least one of colored press concave and colorless press concave.
