Follow the Guangzhou Elephant printing to analyze the reasons why digital printing ink will block the printer head, and make your printing more smooth!

The main reasons for dyes are dye deposition, impurities, and excessive dye solubility. There are many reasons for the clogging of printer head caused by digital printing inks, such as digital printing machines, such as dyes. The reasons for the machine are mainly due to the interruption of ink supply, the blockage of mold in the ink channel, and the blocked air port of the ink cartridge.

There are four main colors of blocked printer head: black, blue, magenta, and cyan, among which black is the most serious, especially when printing a large amount of ink. For insoluble disperse dyes, the particle size of the dye is also critical, and its particle fineness requires no more than 10 particles larger than 0.2 microns within the 0.1 mm field of view of the microscope. This is both related to its dye parent structure and its concentration.

We have found that printer head clogging is greatly improved after diluting the black ink that often clogs the nozzles by 20% or more with diluent. However, at present, black ink itself has the problems of insufficient strength and low color depth. Therefore, reducing the solubility of dyes to improve the phenomenon of clogging the printer head also has certain disadvantages. If the ink is placed for more than 3-6 months, it is also prone to blockage of the printer head. Before use, use a Buchner funnel to filter with two layers of filter paper.

In addition, some inks will have agglomeration phenomenon. Once the ink channel is slightly leaked, it will cause a large area of ​​the printer head to be blocked. To know whether the ink will cause graining, you can drop a drop of ink on the film paper, place it in the air to let it volatilize naturally, and watch the residue. If it is in the form of a block, graining will occur; If not, it will not occur.
