Plastic box printing is a common processing technology for transparent plastic packaging boxes. The printing process can make the plastic box more possibilities. The most intuitive visually, it can achieve more outstanding impact, leaving consumers with deep impression. Many product parameters and presentations can be printed directly on the plastic box, which makes it easier for people who want to buy it to increase their understanding.
Plastic box printing is a general term. In the case of large classification, the printing method of plastic boxes can be divided into two types: one is offset printing, which is flat printing, because their ink thickness is the same, generally used The dots represent the color and layering of the print.
The other one in the box printing is silk screen printing. The working principle is to scrape the ink back and forth, so that it penetrates through the very small holes on the lower plate to achieve the printing effect. The silk screen printing ink can cover up to 2mm thick, and the thick ink is visually very dark and bright, and it is also a common printing type. The silk screen is characterized by a pattern that does not have much color and does not change much in color.
Offset printing and silk screen printing are the two most commonly used printing methods in the plastic box packaging industry. These two printing processes complement each other and have their own advantages in different occasions. Silk screen printing is very suitable for small batches, orders with few colors. Offset printing is tens of times more than tens of times in the speed of printing. There is no way to compare the two in this respect. However, offset printing sometimes has color chromatic aberration, which is often seen in the same batch of printing orders. appear. If it is relatively subtle, it is a normal situation. If the deviation is relatively large, it must be handled as an exception. There are many reasons for this. The working experience of the printing press is a very important part. In the same batch of printing, if there is a small problem in the middle of the process to stop, then the probability of chromatic aberration in the same batch will increase greatly. This is a question to be very careful.
