How to improve the absorbability of universal printer UV ink
添加时间：
Whether the viscosity of universal printer UV ink is stable is the most basic, universal printer UV ink viscosity is too high or too low on the printing effect will not be very good, so the ink viscosity should be controlled within the prescribed range. Universal printer UV ink will volatilize in the process of placement, viscosity will become high, so often to measure the viscosity of the ink.
The drying property of UV printer is also important. Ink drying too fast, the pattern will become very dry, the effect looks not very good, if the drying too slow will be easy to stain some dust and so on, printing dryness and pattern area is related.
This is determined by the printing principle of the UV printer, which selects the principle of piezoelectric inkjet printing, mainly short-plate digital printing. Compared with traditional screen printing, offset printing and other processes, the speed is very slow indeed. But we need to understand that the advantage of UV printer is that DIY customizes all kinds of 3D relief three-dimensional pattern printing, this is its interests, select this machine, the printed material must match with it, if the UV printer to print a billboard, it is certainly a loss of money. This device can be used to print cellphone shell, leather, tile, glass background wall and other raw materials.
If it is water-based label printing ink, PH value to control very well, to the specified range, PH value of ink viscosity is also a certain impact. In the printing process, we should regularly add proper stabilizers to the ink.
