With the rapid development of the printing industry, people's demand for printing quality has also become higher and higher. The printing of the box can be said to be the most difficult and high quality requirement in print. In packaging printing, there will be some problems. As someone who is not a professional printer, it is easier to see the printing problem. It can be said that it is a matter of gloss on the printing packaging. Color is a very important part of the packaging. But it is also often easy to find, so finding the reason for the problem becomes particularly important. Here are three main reasons for this.

1. The good or bad ink can directly affect the hardness of the printing gloss of the packaging box, mainly the smoothness of the ink film, the decisive factor is the nature and quantity of the binder.

2. The pressure at the time of printing is a key factor in the good transfer of prints. If the pressure is too large, the prints will gradually expand around the area. We know that after the expansion, the ink will become thinner, the printing layer will become thinner, and the gloss will also deteriorate.

3. The gloss printed in the packaging box has a great deal to do with the roughness of the surface of the printed paper or the surface of the substrate. If the surface is very rough, according to the optical principle, the surface will cause diffuse reflection, and the reflection can be reflected back. At this time, the gloss will decrease. If the surface of the substrate is smooth and flat, then the gloss will naturally be much higher.

The above reasons for us as a not very professional can simply understand and find the cause of the problem of gloss, so that the printing of gloss and good work can be familiar with these three points. Only by improving the gloss of the box printing, can the overall image of the box be improved, and the box can be upgraded and added value. Jiajie printing specialized in digital product packaging boxes(headset packaging box, data wire packaging box, Bluetooth speaker box, mobile phone toughening film packaging box, mobile phone shell packaging box, etc.) customized, high-end is to pay attention to the overall gloss printed out of the box.
