In order to make plastic bags, we all need to use printing, and we commonly use plastic bag printing methods, offset printing and copper plate printing. What is the difference between them? Today, we will talk about the advantages and disadvantages of these two kinds of printing.
Offset printing
This printing method is to transfer the ink on the adhesive surface to the plastic bag by roller type resin impression.
Offset printing is characterized by simple process, large printing volume, short cycle and low cost. However, due to its special offset, the plate produced is relatively rough, and the precision is not high. Therefore, when printing fine pictures and texts, it is easy to have problems such as inadequate printing, missing printing, excessive printing and rough edges. Therefore, in the printing more fine or higher requirements for printing customers, we will generally use copper plate printing.
Copper plate printing
The printing method is similar to offset printing. It is also used to transfer the ink on the copper surface to the plastic bag through the roller type copper plate impression.
Copper plate printing is characterized by fine printing, no missing printing, multi printing, burr and so on. However, the printing cost is high and the plate making process is more complicated. In order to make a plate that meets the printing requirements, it is necessary to be familiar with the process and strictly control the operation of each link, otherwise quality accidents may occur.
The above two kinds of plastic bag printing methods determine the appearance effect of plastic bag products to a certain extent, but Beite packaging thinks that choosing a good plastic bag printing technology manufacturer is the most important. A plastic bag manufacturer with perfect technology will greatly reduce the mistakes in the manufacturing process. Only in this way can we make the perfect plastic bag products.
