Offset ink factory tutor you how to quickly solve the problem of printing edition plug

In the printing process, printing network often plug version, once the plug version not only reduce the printing quality is affecting the printing efficiency. Even more unfortunate is printing dot products are often large customers, such as Wahaha, Mengniu and other fast moving consumer goods of the carton, these orders, often printing 1000 copies need to stop rubbing the printing version. Once the plug version will increase the amount of downtime, resulting in low production efficiency, but also will cause the loss of carton production. How to solve the problem of plug version.

In general, FMCG products carton outlets more and more delicate, so what is the cause of plug version of the problem? We usually find is stuffed version of ink and printing plates and the operation result.

A, ink

1. The ink flow of poor printing production time, some operations like into the cartridge ink to adjust slowly, make the ink storage volume more in the middle of the roller and rollers. This approach is suitable for full print, because the ink flow is slow, resulting in the increase of the amount of ink on the printing plate, but the printing dot or fine character will appear plug version.

Solution: liquidity prevention printing plug version must speed up the ink, ink pump by adjusting the air pressure can be solved.

2. The ink drying too fast ink from the roller transferred to the printing plate, printing and then transferred to the paper, due to the ink drying too quickly, ink drying on the printing plate, so that the ink accumulation formation of a plug of version of the phenomenon in the print edition.

Solution: the more good judgment, when cleaning printing plate, printing ink is difficult to wipe, general is ink drying too quickly caused, by adding new ink or slow drying agent to solve.

. ink viscosity is too high ink viscosity is too high will cause plug version, causes and mobility difference is the same reason, reduce the viscosity of the ink can be solved.

Again is ink in dust and paper powder into ink, dust through the ink system transferred to the printing version formation plug version.

Solution: through the filtering net is additionally arranged in an ink inlet tube, mesh in 120 mesh can be. To control the printing viscosity, improve color printing concentration, viscosity control is appropriate in 9 seconds.

Two, printing plate and roller matching

Printed version of the mainly due to the mismatch of printing and roller, such as 300 to roller to 80 lines pattern printing, so this proportion will often the plug version, because the net 300 mesh hole is too large, ink transfer assembly in printing ink, printing dot plug version, resulting in printing plate and anilox roll mismatch.

Solution: the ratio is 1:4.5, the ratio is reasonable.

Three, operator error

Operation is mainly due to excessive pressure deformation caused by printing, printing dot and dot block, printing pressure gap is generally about -0.3 mm thickness of cardboard.

Methods: liberation to train the operators, to prevent the printed edition plug phenomenon as a result of excessive printing pressure.
