The factors that affect the quality of color box printing, these points you must know! (I)

The outer image of commodities is becoming more and more important in the fierce market competition. Color box has become the choice of outer image packaging of commodities because of its exquisite and beautiful appearance. Color box is not only light, easy to carry, a wide range of raw materials, and environmental protection. Today we share the factors that affect the printing quality of color boxes.

The process of developing and fixing film after exposure is directly related to the clarity and contrast of the image on film. Therefore, for plate making film, the key to look at the graphic part of the density and the graphic part and the contrast between the non-graphic part. The higher the density and the greater the contrast, the better the quality of the plate film, and the printing quality of the plate produced by it can be guaranteed. In addition, the thickness of the plate making film base also has an impact on the quality of plate making, generally thin film than thick film effect is better.

In the process of printing, the intensity of the light source, the distance between the light source and the plate, and the length of the exposure time will affect the quality of printing. The light source is strong, the distance is short, the exposure time is relatively short; The light source is weak, the distance is long and the exposure time is relatively long.

Under a certain light source and distance, with the increase of exposure time, the photosensitive part of the plate is decomposed more and more until the photosensitive film surface is completely decomposed. If the exposure time continues to grow, no light part of the edge of the film surface due to strong light radiation, sensitive film also began to gradually decompose, so that the printing plate graphic lines will become thinner, even broken, burned. If the exposure time is not enough, the non-graphic part of the photofilm surface is not completely decomposed, the non-graphic part of the plate after development still has the film, the machine will be dirty printing.
