How to solve the ink caused by the dirty plate, flower plate, paste plate phenomenon?
A, the ink viscosity is too large and the phenomenon of flower plate.
Ink formula viscosity is too large, in addition to making the printing process transfer difficult, but also to destroy the ink layer in the middle of the fracture conditions, so that the layout of the remaining ink layer is not enough, because the graphic part of the bare by wear and tear caused by the flower plate.
Solution: Add some de-sticker to reduce the ink viscosity, but does not make the ink mobility increase too much coating online coatingol.com. for printing fine products, reduce the ink viscosity, to use anti-viscosity agent is good. Because it reduces viscosity at the same time, does not increase the fluidity of the ink, and good for ink drying. Note that the increase in dosage to be appropriate, too much will affect the print gloss, generally yellow ink plus dosage of about 1-1.5%, other colors of ink in about 2%.
Second, the ink viscosity is too small and produce a paste version.
Small viscosity of the ink is easy to emulsify, resulting in floating dirty, so that the ink can not be transferred properly, so that the ink rollers, printing plates and blankets on the gradual accumulation of pigment particles. When the pigment particles on the printing plate to a certain thickness, it will cause paste plate. Sometimes due to the layout of the remaining ink layer is not enough to cause the plate.
Solution: appropriate to add some thick ink oil, but can not add too much, to avoid affecting other performance.
Third, the ink fluidity will be too large to expand the network deformation, ink fluidity is not enough to produce a flower plate.
Ink fluidity will be too large to spread the ink layer, so that the geometry of the print expanded, the print can not be correctly replicated; ink fluidity is often uneven distribution of ink, resulting in the printing plate by the lack of ink and flower plate.
Solution: Ink fluidity is not fully adaptable to all printing machines, high-speed machines than low-speed machines to have greater fluidity. Adjustment of ink fluidity of the material generally used to adjust the ink oil and high boiling point kerosene.
Fourth, the ink particles coarse and produce flower plate.
Ink particles coarse, in the printing surface to play the role of abrasive, in thousands of times rolling, so that the graphic base is damaged and caused by the plate.
Solution: When printing as far as possible to use the small proportion of pigments made of ink. For the washout color ink should generally use transparent washout ink or bright pulp as a washout agent, and do not use white ink.
Fifth, too much dry oil in the ink and paste version.
In the printing sometimes in order to make the print fast dry, to already have the drying properties of the ink to add desiccant, promote the degree of aging of the ink roller, and make the ink coarse, emulsified, so that the ink layer on the printing plate can not be broken from the middle, most stay on the printing plate and cause a heap of plate, under the action of printing pressure to make the dot on the ink layer gradually expand causing paste.
Solution: For the dry oil caused by too much paste plate, can not use the method of increasing the moisture of the page to solve, should be cleaned off the old ink on the ink roller to replace the new ink. In the printing parts need to add the right amount of dry oil ink, when the downtime is short, you can apply some anti-drying agent on the ink roller, when the downtime is long, you should clean the ink on the ink roller.
