subject: Digital Printing Activity And Application Of Ink Performance [print this page] Cause nozzle clogging due to a digital printing machine factors and dye reasons, the machinery is mainly due to interruption of supply ink, ink Road mold plug, cartridge air inlet barrier and other reasons. Dye main reasons for the dye deposition, impurities, dyes and other solvent through the Great. The insoluble disperse dyes, the dye particle size is also critical, required particle fineness Microscope 0.1mm within sight of the more than 0.2 micron particles less than 10. Plug nozzle are mainly black, blue, magenta, blue four colors, including black the most powerful, especially in the background color of ink to print a large case. This not only its parent dye structure, but also on its concentration. We found that blocking the nozzle will often use black ink diluted diluted 20% or more after the nozzle clogging greatly improved. Black ink itself but there were insufficient forces, the low color depth, thus reducing the dye to improve the solubility phenomena there are some disadvantages plug. Ink placed 3-6 months or more, also easily produce the nozzle plug, with two layers of filter paper before the application of Bchner funnel filtration. Moreover, some ink particles will end the phenomenon, once the ink Road, slightly left blank, it will cause a large area plug nozzle. To know whether the ink will have end grain phenomenon, a drop of ink to the film on paper, placed in the air after its volatile nature, watching their residues, such as a block sheet, it will produce the phenomenon of end grain, and vice versa not.
