What are the factors that determine the hardcover printing plate printability?
In the hardcover printing process of the printing factory, the printing plate's printing resistance is also an important factor to get high-quality printing flat sheet. Today, the small edition of Meida printing is to simply summarize the factors that determine the printing plate's printing resistance;
1. The internal factors of the plate, which refer to the mechanical strength and chemical stability of the plate itself. Different plate manufacturers will produce different PS plate printing resistance. If the plate is baked, the printing resistance will be greatly improved.
2. In the process of CTP direct publishing, the quality of printing plate may cause PS plate to run out of light, the density of original image and text parts is not high enough, the exposure time is too long, the development is too long and so on, which will reduce the printing plate's printing resistance.
3. For the static protection of the printing plate, we will protect the sun dried printing plate before it is put on the machine, so as to prevent it from receiving too much light, which will greatly reduce the printing plate's printing resistance.
4. For the dynamic protection of printing plate, the pre Press Department of MEDA printing should take measures to avoid or reduce the damage of various factors to the printing plate as much as possible when the printing plate is in the combined state on the printing machine when printing.
