Shaftless Gravure Printing Presses plate roller maintenance

Some flexible packaging factories have thought of many ways to prolong the life of the plate rollers of Shaftless Gravure Printing Presses. The following points should be paid attention to when using the plate roller.

1. Whether it is Shaftless Gravure Printing Presses or ordinary electronic shaft gravure printing machines, before use, please wipe off the anti-corrosion oil on the plate surface and check whether there are bumps, scratches and other problems on the plate surface.

2. The layout should be processed with special equipment. Please do not process it if there is no special situation before the machine. If you want to polish the plate roller, it is recommended to use 1000# sandpaper. Do not touch or scratch the layout with hard and sharp objects.

3. When using, use a special scraper for the plate roller, and never use other metal sheets to replace it. The scraper and the plate should maintain an appropriate angle and pressure according to the specific printing conditions.

4. After gravure printing, the ink on the layout should be cleaned immediately to prevent the ink remaining in the mesh pit from drying and causing blockage.

5. Do not touch or carry the plate roller with bare hands to prevent oxidation and scratches on the plate; especially in summer, it is necessary to prevent sweat droplets from splashing on the plate.

6. In summer, the temperature and humidity are high, so it is not advisable to store the plate rolls in the plate box. When storing, the layout should be wiped clean, coated with anti-corrosion oil (recommended to use 7# engine oil), wrapped with clean plastic film, blanket or corrugated paper from inside to outside, and placed in a ventilated and dry place (temperature 0 ℃ ~ 30 ℃, relative humidity < 65%) environment, and away from acid and alkali corrosive substances.

Adhere to the maintenance of Shaftless Gravure Printing Presses plate rollers in this way, and the operation of printing equipment will save you a lot of time to repair failures.

The printing speed of Shaftless Gravure Printing Presses is determined by these two factors

The printing speed of Shaftless Gravure Printing Presses is first determined by the length of the transmission distance between the colors of Shaftless Gravure Printing Presses. Because of the color registration on the printed matter during printing, if the ink of the previous color is not dry, the ink of the subsequent color will dissolve the ink of the previous color, causing color eating. Therefore, the longer the transfer distance between each printing color of the gravure printing machine, the longer the natural drying time, the faster the printing speed can be increased, otherwise it is difficult to increase the printing speed.

Secondly, the effect of the drying box determines the printing speed. If the effect of the drying box is good, the ink is completely dry. Not only the front color ink cannot be dissolved, but also the residual solvent will be reduced. Gravure printing inks are air-dried rather than heat-dried. First of all, when the gravure ink is heated, the conjunctiva will form prematurely, and the coverage of the color film will affect the volatilization of the solvent in the ink, which will cause the ink to dry. Secondly, the ink contains a variety of solvents with different boiling points, so the volatilization speed of various solvents is different, that is, the solvent with a low boiling point volatilizes quickly, and the solvent with a high boiling point volatilizes slowly. When the temperature is higher, the low-boiling point solvent evaporates faster, and the high-boiling point solvent remains more. In view of the above two reasons, the greater the heating of the drying box of the printing press, the more difficult it is for the printing ink to dry. If the printing ink dries or does not dry, it will cause the printed matter to dissolve or stick. The printing speed will not be fast if the printed matter dissolves or sticks. If the printing speed is slow, the amount of ink will be large, which will easily cause the printed matter to dissolve or stick. By analogy, it is difficult to speed up the printing speed.

Therefore, the ratio of the heating amount and the blowing amount of the drying box of the printing machine must be correct, which is the premise of ink drying. Secondly, if the printing machine oven runs out of wind on the printing plate, the printing ink will dry on the printing plate roller, the shallow screen of the printing pattern will not be printed, and the transition color will also be incompletely printed. Again, the heat of the drying oven should be directly baked on the film, and the film will be stretched accordingly. If the wind blows directly on the film, the film will vibrate. The film stretches and shakes, which will affect the accuracy of the printing register.

Pay attention when selecting and purchasing printing machines. A good drying box for gravure printing machines must have: the heat cannot be directly baked on the film surface, the wind cannot be directly blown on the printed matter, and the wind cannot run like on the printing plate. The blowing volume should be greater than The heating capacity and the exhaust air should be unobstructed, and the performance of the secondary return air is better.
