In printing, how do we choose the same paper, the same ink, without considering other process problems, some card game printing wholesale luster difference is a lot, then if you do not use the film after printing then, There are also a variety of ways to improve the gloss of card game printing wholesale:
Luster, as a kind of visual information, can have an important impact on people's mental state, emotions and many other spiritual aspects, so people's research on color began very early. For customers, a certain commodity on a card game printing wholesale needs to have luster, except for the luster made by technology. So whether the light can be reflected in the printing, we also come to understand.
1, improve the acid edition solution.
It is mainly characterized by Ming acid and phosphoric acid. The stronger the acidity, the greater the resolving power of ink linking materials and pigments, and the greater the corrosion, resulting in the rough surface of imprinted film and the reduction of luster.
2, reduce ink emulsification.
The excessive emulsification of ink in offset printing is mostly caused by large amounts of water and ink in the operation, and the ink layer looks very thick, but the ink molecules become the state of oil in water, and the luster is very poor after drying, and it will also produce a series of other failures. Large ink is a more taboo practice in offset printing.
3, the appropriate additives in the ink.
The appropriate addition of auxiliary agents in the ink can adjust the printability of the ink, so as to smooth printing, most of the auxiliary agents will have an adverse effect on the gloss of the finished product, such as anti-stick agent, the main raw material of anti-stick agent is six grain powder, after adding ink, the surface of the imprinted film is rough due to the precipitation of corn flour, and the gloss of the finished product is poor.
4. Use dry oil correctly.
In the process operation, the correct use of dry oil is very beneficial to the formation of gloss in the finished product. This is because the paper takes a certain amount of time to absorb the binder, and in this process, the binder condenses as soon as possible until the conjunctiva is dry, which is the key to the finished product's good luster.
5. Watch the powder.
Spray powder, like ink, will also produce condensation, especially the bag or barrel that is not sealed well, after the spray powder is damp, it condenses into larger particles, and is sprayed onto the wet ink imprint, making the ink layer surface conjunctival rough, reducing the original luster, so the spray powder should pay attention to moisture resistance.
6. Adjust the machine properly. Whether the thickness of the imprinted ink layer meets the standard also has an impact on the gloss. For example, the pressure regulation is poor, the dot expansion rate is high, the ink layer thickness is not up to standard, and the finished product luster is slightly poor.
