The order of adding ink should be from large to small, that is, the main color ink with a large proportion is added first. The preparation of light-colored ink should first put the diluent, and then gradually add dark ink to the dilute. There are two methods for blending inks: a small amount of ink can be mixed manually; a large amount of ink should be mixed mechanically. The hiding power of ink refers to the ability of ink to hide the background color. The stronger the hiding power, the lower the transparency of the ink. Four-color printing requires high transparency of the ink, otherwise it will affect the color reproduction effect of the printed matter. Adjust the adhesion of ink according to the following factors during printing: ①The surface strength of the paper. The surface strength of the paper is large, and the adhesion of the ink can be adjusted larger: otherwise, the adhesion should be adjusted smaller, otherwise the paper will "fall off". The "hair loss" is very powerful, seriously affecting product quality and production efficiency, which is often the main motivation for adjusting the adhesion of ink. ② Printing speed. When the speed is fast, the requirements for adhesive deployment are smaller, and vice versa. The faster the speed, the easier the "brushing" phenomenon and uneven ink transfer phenomenon, and it is necessary to reduce the adhesion to adapt to it. ③ Layout graphic structure. When printing screen mesh images, the most important thing is that the shape and area of ​​the dots should be copied correctly, and the adhesion should be adjusted larger. When printing a solid image, I hope to get a uniform and thick solid field, and because there is no problem of dot enlargement, the adhesion should be smaller. ④Workshop temperature. As the temperature rises, the cohesion of the ink will decrease, and it will be more prone to emulsification and increase in dot increase rate. When adjusting the ink, the adhesion of the ink must be adjusted in advance. On the contrary, the adhesiveness of the ink is reduced. In the production of packaging offset printing, the ink dries too slowly, and the most common drawback is that it is prone to "scratching the backside". In addition, if the ink drying speed is too slow, the free penetration of the binder will increase, which will cause the ink color to be dull and lack of gloss. The ink dries too quickly, the ink surface layer is easy to film during the printing process, which affects the production process, and may also cause the ink to crystallize, which affects the subsequent ink color printing for dry overprinting.
