CTP version of the scratch problem can not be ignored
Because the coating amount of the CTP plate material is basically about 1.6g / m2, there is no traditional film thickness, and most of them do not have a special protective layer, so the scratch resistance is worse than the traditional version. Therefore, in You should pay more attention to the standard operation when using it. In many cases, the user does not pay attention to the operation when using it. For example, when the version is taken, the version is directly pulled out of the box, instead of removing the box together with the backing paper. The traces are not visible before development, and it is not easy to find after development. After discovering the samples on the machine, a lot of manpower and resources have been wasted. Here are some points for my reference based on my experience: 1. Scratched version-very thin white line, the position is not fixed, it is easy to find on the ground, generally about 1 to 4 cm is mostly in the middle section of the version, because this section just rubs against the box, it is easy to cause Scratched. The solution is to take out the backing paper together, or take the entire package out of the plate box and place it on the plate rack to avoid pulling. 2. Scratch-in version is also a small white line, but the position is relatively fixed. The location of different machines is different, basically caused by friction with the panel, the small version (below 900) is more prone to this kind of failure due to the stiffness. The solution is very simple, just wrap the area where the panel and the plate contact with transparent tape. 3. Scratching of the printing plate-if you do not pay attention to the cleaning and maintenance of the developing machine, there will be crystals on the rubber roller. These crystals will leave a short scratch on the plate surface, and sometimes there are, sometimes not . The solution is to work hard and clean the developing machine every week (up to two weeks). small pet cage,large pet cage,homey pet cage,pet hammock for cage Ningbo XISXI E-commerce Co., Ltd , https://www.petspetscleaning.com
