Shu water-based ink water-based ink printing machine

Use of water-based ink paste in the production process is preferred to add a dispersant and wetting agents. General Ink fineness between 101μm ~ 25μm better, too small or too big an impact on the water-based ink ink flow and rheology. Ink viscosity means thick, and is an indicator of the performance of the ink flowing. Too viscosity caused by poor liquidity, slow drying; low viscosity ink fluidity, fast drying ink thin, use less ink. Such as low ink viscosity, the toner content requirements to be high; otherwise, the toner content was low. Since the viscosity of a direct impact on the quality of ink transfer and print, to that end, the ink viscosity control is very important. In the printing process, the viscosity is too low will cause light color, high viscosity will cause dirty version, burnt version of such phenomena, it is difficult to control when you join the transfer agent, can improve the transfer effect, increasing the colorful and three-dimensional sense. Water-based ink tips 1, can not be mixed with ink and solvent inks. When in the course of appropriate additional water, you do need to adjust the viscosity or the drying rate, amount of added alcohols or esters and other additives. 2. Stir well before using and then poured into the ink tank, adjust the viscosity of water, can be used. Unused should be covered drums, can not let the ink volatile in nature. 3, should be tested before use various technical indicators, especially hue meets their requirements, if the hue deviation is large, please notify ink manufacturers to deploy appropriate, in order to avoid hue error caused by the dispute between the two sides. 4, in the printing process due to volatilization reason water will affect the original ink viscosity and PH value, we need to frequently check the viscosity and PH value, should the need for appropriate PH value added purified tap water or stabilizer. 5, the residual ink on the printing equipment rinse after printing applications, printer ink on the anilox roll is best cleaned with a cleaning agent, in order for the next printing services. Improper Use water-based ink out that not all users are aware of the aqueous ink viscosity principle, there will be a lot of people live under the illusion that the large ink is good ink viscosity. You can add a lot of water, more printed cartons, reduce costs and improve efficiency. In fact, not based on the performance of production equipment, blindly buy high-end ink that can be printed with high-grade ink on good quality prints, it is very impractical and unscientific. High-end ink easiest test is whether there is lost color, but do not think losing color ink is upscale, or that high-grade color ink is not lost, are not particularly accurate to say
