In flap book printing, there are many uncertain factors that affect the quality of flap book printing, including the reproduction of the color of the plate before printing, the accuracy of the picture, etc. There are many factors that ultimately affect the quality of flap book printing. We will look at the quality control of some of the more important processes and how they affect the quality of flap book printing products.

In flap book printing, if we have problems in the early stage of flap book printing, no matter how good the flap book printing material is, no matter how high the quality of flap book printing machine is, No matter how beautiful the binding may be, it may be some discarded flap book printing products. In the early stage of flap book printing, it is a very important link for the design and making of plates. Whether there is a problem with a word or a problem with the size, it will cause certain losses.

The basic thing of flap book printing is to copy the color of the product, and the color is often expressed through pictures. Image scanning is to convert the color information on the picture into digital signals that can be stored and edited by scanning equipment, and then pass the image processing software. These digital signals are processed by our flap book printing application.

The ability to reproduce the image accurately and with high quality, that is, to retain the tone, level, contrast, saturation and other information on the original as much as possible, is the basic standard to measure the scanning quality of the image. The flap book printing manuscript can be divided into two types: reflection manuscript and transmission manuscript. Reflection is divided into photos, flap book printing, hand-drawn drafts and printed drafts, etc., transmission drafts are divided into positive and negative, each type of manuscript has its different characteristics, so when flap book printing we have to choose the characteristics of the manuscript to print.

The ink is made of the color powder and the resin binder. The pigment particles are wrapped with a layer of almost transparent resin oil. The light of this layer of resin oil has the effect of refraction and reflection, so we feel that the black ink flap book printing still has a certain luster on the substrate. In the ink color matching process, according to the actual flap book printing process. Ink layer thickness, flap book printing substrate and other conditions to determine all ink. In the selection of ink, to consider the ink itself hue, gloss, coloring power, covering power and so on.

Gloss can be measured either by instrument or by the naked eye, and is usually observed only by the naked eye during the color matching process. Gloss actually refers to the ability of the ink flap book printing sample to reflect light in the same direction after light irradiation, which directly affects the flap book printing product and is a very important indicator. At the same time, when selecting ink, it is necessary to distinguish between the ink itself is bright, rich halo matte ink, to avoid mixing errors.

These are some of the basic elements of flap book printing, color, coloring, ink, gloss, etc. When the machine is on flap book printing, the manual should also keep checking the flap book printing.
