After the completion of the plate printing, in order to reuse the screen, a series of operation steps such as screen deinking, stripping (photosensitive film), and degreasing cleaning are often required. Since many small-sized stores take over some short-lived products, stripping and cleaning are particularly important. This not only saves costs, but also shortens the time required for cumbersome processes such as stretching. However, according to the conventional method, it takes time and does not cost a lot of materials (solvents). If this series of processes can be completed at the same time as a special screen cleaning machine, it will not only waste solvent and release agent, but also It also saves time, improves work efficiency, and reduces costs. According to the characteristics of the commonly used volatile drying ink, that is, a single solvent volatilizes, the drying speed is fast, the ink type is large, and the use ratio is large (accounting for 80% to 90% of various screen printing inks). The use of front cleaning, reverse film removal, positive and negative degreasing methods, so that the ink can be like water-based paint, easy to clean, and does not leave residual ink, the effect is very good, not only suitable for volatile drying type oily printing plate, but also suitable for all types Non-dried oily printing plates, even for oily printing plates with longer storage time (weaving drying inks for plate inks) can be quickly removed, leaving only a faint "ghost" due to long drying times. The ink penetrates deep into the interweaving of the screen, but it does not affect the reprinting. After the two days of printing, the oily screen has no “ghost†after the film is removed. The method is: First, the excess ink on the printed plate is used with a doctor blade. Remove, and put the printing surface of the printing plate face down, paint brush on the back of the screen with a little oily paint remover (I use a new linoleum stripper), pay attention to the quality of the release agent and ease of release Relevant, should use a special release agent, because the back of the ink, the release agent can react with the film, and scratch the surface of the ink can not react with the release agent, the use of solvent cleaning methods. Use a brush to dip a little solvent, such as 783, cyclohexanone, and pore opener, etc., to fully brush the ink. (The opposite side must be brushed and allowed to react for about 20 seconds. The ink residue and film at this time After separation, the detergent or laundry detergent is applied to both sides of the screen, placed in the pool or the tap without washing, and the solvent and release agent are used for the screen which is not damaged by itself. The original method saves much time and greatly saves time, and the washed screen plate can be dried after being dried.For long-term screen plates, an alcohol scrub screen plate is applied before plate making to remove dust, without cleaning the roughened screen. However, this method (integration of stripping and cleaning) is not ideal for chemically consolidated screens and waterborne printing plates. For re-exposed oily printing plates, the number of meshes is more than 300 mesh. Flushing removes the film that remains in the interweaving mesh.
