Treatment method: 1, with a feeler for the appropriate adjustment, adjustment can be reversed in the printing plate, so as not to damage the printing plate grain, while the total plate pad should meet the requirements, adjust the force of the water roller on the plate is generally 0.2 Within the range of ~0.5mm, but also according to the specific circumstances, such as: the new water roller sleeve should be slightly smaller with the force of the printing plate adjustment, and gradually adjust with the use of different degrees; old water roller on the printing plate The force should be moderate. Because of the small change of the old water roller sleeve, the larger the force is, the easier it is to rub the printing plate; 2. The micrometer is used for specific adjustment. Under normal circumstances, the pressure is in the range of 0.10-0.15mm, and the difference in the thickness of the printing plate should also be noted. The impact of printing pressure; 3, should be based on the situation of the paper, ink flow size, graphic conditions and print size to timely scrubbing blanket; 4, as little as possible to use more paper powder paper, even if used should also often scrub blanket And continue to add new ink, etc.; 5, it is best to avoid the use of, even if the use should also be in the low-volume prints, the printing liquid PH value should be maintained at between 5 to 6; 6, the fountain liquid should be presented It is weakly acidic, and the bucket should be cleaned regularly to avoid deterioration of the water hopper. 7. Replace the printing plate. Even if it is used, the printing plate should be printed with less quality and less printing. The degree of use, so as not to affect product quality; 8, should not be used for printing; 9, selected in the low-volume and print quality requirements of the job is not high; 10, change the use of blanket direction. In order to avoid mistakes during installation, the best way is to use the hand to grasp the two ends of the blanket to pull a pull, the direction of use is not obvious for the extension, you can also use the identification of the north side of the blanket to determine the direction of use; 11, the replacement of the printing plate or in the use of low-volume prints; 12, the development of the plate should be based on the developer and the sensitivity of the plate to the correct development, due to improper development caused by thinning the resin film should replace the plate; 13 Replace the blanket; 14, adjust the ink, remover, improver and other appropriate adjustments, and according to the situation and the type of ink to determine the amount of use; 15, due to the density of the printing film caused by insufficient plate quality problems , should be put an end to use; 16, it is best to avoid the use, even if it should be used in low-volume and print quality requirements are not high in the living; 17, after revision repair paste paste (agent), should use one side Amount of water flushing to the non-text at the wipe; 18, replace the water roller sleeve; 19, adjust the ink roller with a feeler gauge, at the same time pay attention to whether the total thickness of the printing plate lining to meet the requirements; 20, replace the printing plate; 21, should Prints with lower quality requirements and fewer prints Used in the product; 22, in the case of the printing plate is not inked, the water roller on the plate should not idle too long machine; 23, with the wetting powder to control the stain on the plate, the graphic part may not Too much force to avoid damage to the printing plate resin film; 24, the use of cleaning agent or petrol washing water roller, after washing the water roller sleeve shall not remain in the cleaning agent or gasoline residual liquid, should be scraped off the net; 25, when the version should Pay attention to the inspection on the back side. Due to inadvertent inspection of the part of the plate after the upper plate, the lower plate should be disassembled and placed on the surface of a flat surface. The block above the convex plate at the front of the plate should be thicker. The film base should be flattened with a relatively smooth wood board or bamboo board. When operating, care should be taken not to slip the film base, and it is not advisable to use excessive force to avoid damaging the grain. 26, the paper is easy to lose powder, and the quality of the printed matter is not high enough. Do not make overprinted prints, can slightly increase the amount of fountain solution, so that the ink has a good transfer, but also should pay attention to the use of more water resistant and difficult to emulsify the ink; 27, both sides of the rubber and the tail easy to bring Dirty, should always wipe the rubber and the corresponding part of the impression cylinder 28, replace the appropriate parts or for proper repair, do not replace the accessories should pay attention to reduce the speed of printing; 29, the hardness of the hard pad than normal should not be used to prevent the machine from generating a large vibration or easy to make the plate subjected to severe wear 30ã€If the layout is dark brown or more serious grayish black after baking, generally do not have to use; 31, replace the printing plate or use in the low-volume job; 32, the aging of the ink roller should be replaced seriously, Less serious rubber cleaner can be used to reduce the cleaning agent, printing speed should not be too fast; 33, the blanket is too loose should be given tight, especially the new replacement rubber and liner after a period of time prone to relaxation, should Pay attention to timely tightening; 34, due to the use of ink for a long time or due to mixed with more paper powder should be replaced ink; 35, should pay attention to scrubbing blanket after changing version, not continuous use; 36, flattening or replace the rubber lining or liner The blanket operation caused by uneven padding should be promptly repaired or replaced. 37. In printing, the ink itself has a certain protective effect on the printing plate resin film, and it is easier to wear out the printing plate when the ink volume is too small; 38ã€Choose the center distance of the roller, and use a micrometer to measure the pressure. Under normal circumstances, the pressure is in the range of 0.10~0.15mm. 39. It is advisable to wipe the blanket, and when there is more paper powder accumulated at the slight wrinkle of the paper, Partial cleaning should be performed to avoid the possibility of abrading the plate more easily. 40. Use a micrometer to adjust the pressure balance. 41. Remove the lower plate, remove the attached debris from the gasket, and raise the part of the plate. The front side of the press sheet is flattened with a smooth wooden board; 42. Remove the barriers under the blanket to remove obstacles, the blanket or liner should be replaced or properly repaired; 43. Remove the blanket, cut or Cut the original hole, use the ruler to measure the parallel size and re-drill the hole; 44. Replace the wipe gauze; 45. Tighten the roller sleeve or replace the corresponding fittings; 46. Use a micrometer to measure the required thickness.
