The quality of jewelry packaging boxes has a great role in promoting jewelry sales. There are usually many factors that affect the quality of jewelry packaging boxes. We summarize them as the following aspects.
1. In Jewelry packaging box printing, sometimes the layout will be arranged with multiple patterns horizontally, so in this case, there may be a problem that the colors of the patterns on the left and right ends of the printing plate are different. Especially in the process of plate making, when the electric engraving is performed from left to right, there may be some changes in the size of the dots, so there will be some differences in the printing effect of the left and right ends plate cylinder during printing.
2. If the room temperature in the printing workshop has a large changes, the flow of the ink will also change due to the temperature change. Therefore, it is generally necessary to control the temperature at about 23 degrees Celsius for color box packaging in most production workshops. Then, when printing ink in winter, it needs to be preheated in advance to ensure that the fluidity of the ink can be increased during printing.
3. If the dots are blocked, the transfer of ink will decrease, so the color of the printed matter will be different from the design. When there is a blockage problem, it is necessary to use a solvent or a special cleaning agent to clean the printing plate.
4. The wind blowing in the printing conditions will also cause the printing speed and drying speed to change, so it may cause some changes in the color of the printed matter.
All of the above factors may affect the quality of the finished jewelry packaging box after printing, so it is necessary to strictly follow the method when processing.
