The PS version through the ink treatment can increase the photosensitive function of the photosensitive layer and protect the graphic and text department so that it can be quickly inked during printing and proofing. At the same time, the rubbing of the developing ink can prevent the light from acting and can prevent the graphic department from Light response, prolong the use of the printing plate, and ink is also beneficial to improve the printing rate. Therefore, in addition to rushing to print on the machine, it should adhere to ink processing, manipulation should pay attention to the appearance of ink to be even, the layout can not afford to clean. Looking at the supply After the fixed PS plate is cleaned and dried, it can be baked on the machine so that the adhesive layer developed by the alkaline solution will not play a role after being heated, so that the residual alkali solution will be volatilized by heat. The department has good lipophilicity, fast ink, and high printing rate. When handling, you should pay attention to the version that is processed through the baking plate. Before the ink is removed, the plate must be cooled and have a certain amount of moisture. If necessary, a thin layer of thin glue can be applied to avoid ink lifting. Face the environmental and machine maintenance 1 It is necessary to clean the studio environment, especially the plate glass, and clean it before work. The developing machine should be cleaned and maintained on schedule. 2 Light source and illumination should be checked on schedule. Voltage, grid inspection, 380V (360~400V). The 3PS version of the storage location should be set in a cold room, or a low temperature and dry place, especially to avoid the sink. When using the PS version, be careful not to bend or scratch, and be careful not to touch the layout with hands covered with oil or developer. Faced with phosphoric acid solution Hand-developed plates are treated with 2% to 3% phosphoric acid. Since the sensitizer in the exposure department after development is removed by the developer, the graphic agency without light is not eroded by the developer, remains on the plate, and has photosensitivity, requiring 2% to 3% of dilute phosphoric acid solution. Fusing fixes the surface of the alkaline printing plate, causing the graphic and text department to confuse. Should pay attention to manipulation, do not just take out from the development of the use of phosphoric acid treatment, should be washed with clean water, rinse the developer and then deal with. Dealing with dismissal When the developed PS plate is used for Chen Sheng, it usually adopts wet Chen Sheng. Although this method is easy to remove, it will be dirty due to some deficiencies in the previous development. The best way is to first wipe a thin layer of glue, after drying, as if it is not dry, and then remove the dirty effect is good, the layout is not clean and play a certain role. Face up to scratch The operation must face up to wipe the glue thin and average, effectively play a role in protecting the layout, and often do not face up to this work in the daily production, glue thickness and inconsistency, and even wipe is not complete, resulting in Plate partially damaged A Privacy Fence is a type of fence that is designed to provide privacy and security to a property. It is typically taller and more solid than other types of fences.
Privacy fences are commonly used in residential areas to create a barrier between neighboring properties, blocking the view from outside and preventing strangers from easily accessing the property. They can also help reduce noise and provide a sense of seclusion.
Privacy fences are commonly used to enclose backyards, swimming pools, and other outdoor living spaces.
