What are the factors that affect the quality of book printing?

  • Oct 18, 2019
First of all, the uneven thickness of the ink layer will result in poor quality of the book printing. There are usually two ways to increase the thickness of the ink layer. One is to reduce the amount of the liquid in the case where the total amount of the ink is constant; the other is to increase the amount of the ink in the case where the amount of the liquid is constant. The principle of the two methods is the same, and which one can be used, as long as the thickness can be adjusted uniformly.

Secondly, it has something to do with the water roller. This is a very important part of the press, which is in direct contact with the plate and provides dampening solution. If it is too much pressure or too small in contact with the plate, it will make the plate surface appear. Therefore printing companies must control the pressure.

Finally, it has something to do with the blanket. There are two kinds of blankets, one is a plain blanket and the other is an air cushion blanket. When it comes into contact with the printing plate, it can transfer the dampening plate to the surface of the blanket because of its certain adsorption characteristics. When the surface is insufficient, it needs to be replenished in time, but the amount of replenishment is a key. Too much or too little is affecting the effect of book printing.

Of course, in addition to the above three factors, there are many factors that affect the quality of the print, such as the size of the printed graphics. Therefore, it is required that the book printing manufacturers grasp these factors when printing, so that the quality of the printed matter is better. As a consumer, they must also choose a good book printing manufacturer.
