Offset printing is a way of printing, widely sheet-fed printing basic is offset printing, this way of printing with high speed, high printing resolution, overprint accurate, printing level full, but shallow, poor durability and ink layer is not suitable for printing bright color label product.
Letterpress copy good graphic definition, printing high speed, high color strength and durability than offset printing, silk screen printing is just slightly worse, but the level and accuracy are better than screen printing and flexo, therefore our country mostly adopts letterpress printing labels in the form of production.
The biggest advantages of silk screen printing is the ink layer is thick, good covering power, but the level of slow and reflect poor, set of low accuracy (this refers to the domestic general level), so the silk screen printing machine can be used to print the administrative levels which is not strong.
Flexible printing quality characteristics is centered, abroad more use this way to print labels, but the technology of anilox roll need high requirement of processing and the technical level of workers, while the machine is simple but the process is quite complex, in the domestic not more adopted labels printing this way.
If you want to printed out one of the most beautiful label, you need all kinds of craft in the printing process effectively together, will integrate the advantages of different printing way, form a greater advantage.
