What kind of color printing packaging is neutralized by acidic ingredients?

In the process of studying the quality of color printing packaging in Dalian, it is found that the acidity and alkalinity of the paper will also have a certain impact on it, and some users have always mistaken that alkaline paper will be conducive to the drying of ink, so in order to improve efficiency, it will also make the paper alkaline. But in fact, although this can speed up the drying process, the alkaline substances in the paper will neutralize the acidic components in the water during the printing process.

Affect the pH value of the embossing solution. In this process, there are many factors that will affect the quality of color printing image, such as equipment, materials, staff Technology and so on. These objective factors can be controlled to improve the quality of color printing packaging. In addition, it may be constrained by all the factors involved in the replication process.

This includes the correctness of the data of the gradation, color tone and clarity quality of the color original image, the manipulation and non-confusion degree of the copying and printing processes in the printing process, the density of ink layer, the efficiency of overlay printing, the chroma and so on, and the adaptability of various equipment to printing materials. The size of the disc paper is to measure the width of the reel. The measurement results are expressed in millimetres, accurate to 0.25 mm, and measured by vernier calipers with accuracy of 0.02 mm.

Through the color box packaging, we can see the inner products intuitively, but in order to make it more beautiful, we need to measure the ink drying speed too fast, ink concentration too light, poor flow and other phenomena in the process of color printing packaging and printing according to the above methods, we can speed up the printing machinery, which not only prevents the ink from drying earlier on the plate, but also overcomes the package. The crust formed by film forming of printing ink eliminates the spotted faults of pictures and texts.
