The reason why the treadmill printing machine is not recommended to print white ink

nowadays,Treadmill printing machineAll are based on color printing, mainly using screen printing white glue to replace the white ink for the printing base, and then printing the color paint ink. The operation is still a bit complicated, and the printing plate is still required when the quantity is small. fee. There are also white ink printers on the market that do not require plate making, directly spray white ink, and print white and color at the same time, but this type of model is only a small model with one-piece or two-piece printing. What is the reason that the treadmill direct-injection printer is not used How about the same out of white color?

The editor analyzes from the following points.

(1): White ink on the market is very expensive. Take DuPont, which is the most widely used, for example (the price is around 1200 RMB when consumers get it). It takes 25ML-30ML white ink to print one square, and the cost of one square white ink is 30 Yuan-36 Yuan, the white ink cost of an A4 size screen is 2-2.5 Yuan, plus the cost of pre-processing and color ink, at least 3 dollars. So the cost directly limits more users to use!

The white ink prices of other manufacturers have many advantages, but one is the whiteness of printing, the color fastness after printing, and the stability.

(2): Treadmill direct-injection printing machines now mostly use 2-3 EPSON nozzles, most of which use the 5th generation (186,187,158,160), the 7th generation (189), 5113 (water-based), 4720 (for water and oil) These nozzles. (The biggest advantage of EPSON is that the ink dots are small, the printing is fine and the effect is good. This is the advantage of EPSON, which is the reason why 99% of the treadmill direct-injection printing machine chooses EPSON!) The treadmill direct-injection printing machine is generally 1.3 -1.6 meters wide, the white ink pipeline generally needs 4-5 meters long. The EPSON print head machine does not need a secondary ink cartridge, so there is no way to circulate the white ink (only install a stirring device in the ink cartridge), 4-5 meters If the white ink in the ink tube does not flow for a long time, the white ink will precipitate and block the nozzle.

(3):Cotton Direct Injection MachineWhen only white clothes need to be printed, the white ink nozzle is not working. The combination of the nozzle and air for a long time can easily cause the white ink to agglomerate and block the nozzle.

(4): When it is necessary to print black clothes, the white ink cannot be circulated, so the white ink must be removed from the entire pipeline before the desired effect can be printed. A lot of waste!

(5): EPSON series treadmill direct-injection printing machine, there is no way to achieve the wet printing scheme, only the dry printing scheme, which requires that all dark clothes must be pre-treated before printing , The utilization rate of the machine is not high!

(6): Because one of themT-shirt direct printing machineThe print head uses white ink, and there is only one color ink print head. The overall efficiency is reduced. When only light-colored clothes need to be printed, the overall output is not high!

Therefore, based on the above reasons, the white ink of the treadmill direct-injection printing machine is not suitable for the current market demand. Although it is convenient, the cost is too high, the nozzle loss rate is large, and the production capacity is low. It is not suitable for the clothing printing industry, which is mostly small and medium-sized enterprises. So now the treadmill direct-injection printing machine on the market still mainly prints in color.
