PEPA offset printing 1. Process Design (1) design of the plate due mainly reflected gorgeous pearl paper paper pearl effect, if a very large area of ??printing inks, a pearl effect is not reflected in the paper, two paper pearl effect by ink has been greatly weakened. So, we try to avoid large areas of solid pattern printing plate design shall be based on the characteristics of pearl paper. General design simple lines, patterns, text, either highlight the focus of the package contents, and can display the paper gorgeous effect. (2) the production process due to the pearl paper pearl particles are easily broken, semi-finished products can not withstand the repeated transfer order, friction, so the production process route should be as short as possible, eliminate some optional process steps, especially those involved in manual more links. Can be printed once completed's not twice, can not offset printing screen printing, polishing machine can not even offline coating, PEPA preferred billion letters, of course, can not polish determined not to polish, pearl paper provided as glazing will greatly weaken the pearl paper pearl effect. 2. There are three printing inks can be used for printing pearl paper, printing effect is good or bad according to their order of: UV inks, non-absorbent paper for the printing inks and conventional inks. Art paper can be applied to book covers, catalogs, brochures, invitations, greeting cards, high-grade office paper, business cards, high-grade packaging paper and so on. First, the different angles of the classification 1, from pulp to see. High quality specialty paper pulp, mostly for the pure pulp, long fiber more, some also contain cotton composition. After such constitute papermaking pulp, strength, toughness, stiffness and good elasticity paper, color also bright. Plain paper pulp with a certain percentage of non-wood fibers, paper, easy to turn yellow, pearl paper, coating treatment is usually required. 2, from the stained look can be divided into pulp dyeing and staining: staining is when the paper pulp slurry was added toner, so that the color evenly distributed in the paper fibers, the paper color saturation uniform cross section inside and out. After staining is in the paper forming with invasive manner pigment dye on the paper surface, color stability inferior pulp dyeing, bleaching water prone, prone to dark paper when folded white edge, high-grade pearl paper, undermine the overall effect. 3, from embossed way of looking at can be divided into before and after embossing Embossing: Embossing refers before the pulp is not completely dehydrated through soft blankets, according to the paper fiber felts of natural grain distribution, form a special texture of the paper. Paper embossed front lines of the transitional nature, delicate, will not hurt the paper fibers. After the embossed paper is finished after a carved steel rolls, the use of mechanical pressure to the paper pattern. Advantage is that after embossing process is simple, relatively low cost, convenient and easy. But this process on the paper fibers have hurt, so the quality of the base paper directly affects the quality of the finished paper after embossing. Little change in the law after the embossed pattern, embossed pattern slightly compared to previous mechanical, dull. Second, the paper and design pearl paper, million Nobuhiro Paper, pearl paper provided by Dongguan City billion letter macro Paper Limited. Pearl paper, million Nobuhiro Paper, pearl paper provided Dongguan City billion Nobuhiro Paper Co., Ltd.
