Why does the PS version have a low printing resistance? A: The PS version is a pre-coated photosensitive material. The printing is composed of many links, and each link must be strictly operated to ensure the quality of the printing. There are many reasons for the poor printing durability of the PS version. The printing conditions of each printing plant are different. The use of strong plate cleaning agent and cylinder cleaning agent in the cleaning agent; excessive printing pressure; too much paper powder, etc. may cause a drop in the printing durability. The main countermeasures for treatment are illuminated with yellow safety lights to fully block harmful light; remake the positive film (density above 1.5); develop under standard conditions; configure appropriate developer, pay attention to development time; do not use inappropriate drugs ; Reduce the number of wiping; use a relatively mild cleaning agent; adjust printing pressure, etc. The printing plant can refer to the above reasons to see if it has neglected a certain link. At the same time, it can also participate in the plate-making training held by Fuji Star Company to master the correct exposure, development methods and operating procedures to achieve the best use of plate materials. What's the reason why the page becomes fictitious after printing? What are the solutions? Answer: If the layout is false, you can start from the plate-making machine and the conditions for the plate-making. The main reasons are: dirt on the glass of the plate-making machine, foreign matter or dirt attached to the film; improper collage of Yangtu film; collage of photos and PS The vacuum tightness of the plate is not enough; the liner of the printing machine is not suitable; before exposure (when punching), or after exposure to development before running out; over-development (over-high liquid temperature, long time, high liquid concentration), etc .; The solutions are: clean the glass or film with a cleaning agent; remove the film from the image part by more than 3 mm; confirm whether the film is close to the PS version, and then expose it; adjust the liner to make it flat; in safe light Next homework. Be careful not to add too much replenishment solution to prevent the developer from being too concentrated. You can also try Fuji Xingguang's powdered matte products, which can effectively solve the above problems. Why is there still unexposed drug film on the PS plate after development? A: This situation has occurred in various printing plants to varying degrees. The main reason is that the activity of the developer has been reduced, and it has not been replenished in time. After exposure, the PS plate has dirty spots and foreign objects, which hinders the development. Precautions: First, increase the concentration of the developer, Second, extend the development time appropriately, Third, increase the developer temperature, Fourth, replenish the developer in time, Fifth, prevent backwashing of the developing solution in the developing machine. As long as you pay attention to the above five points, you can develop the ideal PS version. After revision, how to deal with dirty parts? Answer: Analyzing the causes of this problem, there may be the following: 1. Insufficient alteration. Among them, the amount of correction fluid is small, the moisture of the plate is not dried, the correction time is short, and the correction fluid becomes xxx quality (open the lid to store), etc. will cause the problem of insufficient correction. 2. The alteration time is too long, the hydrophilic layer is destroyed 3. Dirty nib 4. Poor oil repellency and glue marks after correction. The following measures are recommended: Use pen tip to make up for revision fluid Before the correction, remove the water from the layout Correction time 30 ～ 40 seconds, then wash with water Cover the cover when using it 5. After alteration and washing, apply the PP-â… PS version protective glue (manual) or PP-â…¡xxxx PS version protective glue (machine use) What should I do when the photosensitive layer peels off or detaches? Answer: Analyzing the causes of this problem, there may be the following: 1. Scratches and scratches caused when using the PS version 2. Scratches and scratches caused by pressure 3. Store the PS version in a place with vibration 4. Wipe the layout with cotton cloth, etc. 5. If the developer concentration is too high, the following measures are recommended: Be careful not to rub the PS layout PS version of the bracket should not be placed in a place with vibration The concentration of the developer should be appropriate. What should I do if the ink is not good at the beginning of printing? Answer: Analyzing the causes of this problem, there may be the following: 1. The specified glue or glue is not used too thick 2. Uneven coating 3. The drying temperature is too high 4. After applying glue, contact with strong light 5. It is recommended to take the following measures for storage under high temperature and high humidity after plate making: a. Use Fuji Xingguang supporting products PP-â… PS version protective glue (manual) or PP-â…¡xxxx PS version protective glue (machine use) b. Dilute the glue properly c. Hand glue should be clean and dry d. Set the drying temperature below 60 degrees e. Prevent light exposure after applying glue f.
