The standardized management of the plate-making process is very important. The plate-making process involves multiple procedures, including order acceptance, draft review, color separation, and design. Machining, electroplating. In the process of electro-engraving and proofing, all processes must be institutionalized and standardized management and control. Things to know before making a plate Before formulating the plate-making process, we must understand the customer's printing production conditions and figure out the requirements of the live parts. 1. In terms of printing technology, there are the difference between surface printing and inside printing. The performance capabilities and processing methods of the two are different. 2. The performance of printing equipment, such as the overprint accuracy of domestic gravure printing machines. Printing speed, stability, etc. are generally inferior to imported gravure printing machines. This should also be taken into account when making plates, which cannot be generalized. 3. The types of film materials used are different, such as OPP film and PET film. Matting film and pearlescent film, their respective properties are also different, the printing process and requirements are also different. In addition, the customer's production environment, such as whether the workshop is closed. Whether a constant temperature and humidity device is installed, whether it is clean, etc. are also very important. The gravure plate-making factory must carry out the "individualization" of the plate-making process according to these situations. Industry tips 1. The stability of the customer's printing process is very important, otherwise it is difficult to obtain stable and consistent products. Generally speaking, the production conditions and process control of large customers or printing plants with a certain scale are relatively stable. Therefore, you can also stabilize a corresponding electro-engraving process curve, and then make some corresponding fine-tuning during the plate-making process according to the specific requirements of its different jobs. 2. Some customers are often limited by printing equipment and production environment, and often have poor ink transfer rates. The loss of small dots in highlights and shallow nets, but customers want to be able to print qualified products even under such production conditions. Therefore, they may ask the platemaker to help them solve the problem. In the case of such jobs, some necessary measures can be taken when making electric carving files. For example, some customers can not print out the small dots of less than 3%. When encountering large areas of high-gloss small dots, they should consciously avoid 3 For small dots below 5%, increase the dot value of the highlight part properly to ensure that the customer will not lose screen when printing. 3. Proofing is also an important part of the process standardization control of the gravure platemaking factory, such as the brand and brand of ink used for proofing, the viscosity of the ink, the speed of the proofing, the pressure of the proofing, and the temperature and humidity control of the proofing room. At present, the common practice of the gravure platemaking factory in proofing is: according to the different requirements of customers at different levels, different grades and qualities of ink are selected when proofing. According to Mr. Wang, the inks used by Toyo in proofing are roughly divided into high and low grades. Generally speaking, large customers or high-end products use high-grade inks for proofing, such as D, C and Dalian Schmidt inks; For small customers or ordinary products that are not too demanding, low-grade inks are used in proofing, which can avoid the low-grade inks used by printing plants to avoid the effects achieved by high-grade ink proofing by platemakers; secondly, platemakers can also Save a certain cost.
