Dye-Sub Printer-Precautions When Using Ink Tube for Long Time

Dye-Sub Printer needs to periodically clean the internal ink tubes, because after a long period of use, the particulate matter in the ink gradually accumulates, which may block the ink tubes. A special printer cleaning solution can be used to clean the ink tubes. The cleaning solution is a kind of "detergent" formulated according to the characteristics of the ink. Its main function is to have a strong flushing ability, a dissolving ability, and a better fluency of the ink in the pipeline. Let me briefly explain how to use the cleaning solution correctly:

First, when new dye-sublimation printers are installed, it should be noted that before each machine is shipped, the machine is filled with ink, and there are protective liquids in the pipes and ink heads. The solubility of the ink in the protective liquid is not as strong as that of the cleaning liquid, and the protective liquid has some influence on the fluidity of the ink, and the phenomenon of drawing (in the high-quality mode) and the oblique flow of the ink hole often occurs. Therefore, we require that the cleaning fluid must be used to clean the pipeline when the machine is newly installed. Avoid the phenomenon of drawing and ink hole oblique spraying.

Second, use the cleaning solution to clean the wiper and ink pad of the sublimation printer regularly every week. Pure water and alcohol have low solubility in ink, and alcohol has a slight corrosive effect on the blade. Therefore, we recommend that you do not use pure water or alcohol to clean it.

Third, regularly use the cleaning solution to clean the ink line of the digital sublimation printer. It is recommended to clean it once every 3-6 months. When the ink is used for a long time, there will be deposits on the wall of the tube, and the attached matter will affect the fluency of the ink, and the cleaning liquid has a strong solubility to the attached matter, so the pipeline should be cleaned regularly.
Fourth, sometimes the working environment is relatively poor, the static electricity of the machine is relatively strong, and many cotton-like dust will adhere to the surface of the ink head. If it is not cleaned for a long time, the ink hole will be obliquely sprayed and blocked. Regularly drip the cleaning into the ink pad to make the ink head more moisturizing.

Replacement Plotter Digital Printing Ink Operation Guide

Different digital plotters use different digital printing inks, and there are many different chemical reagents inside them. Therefore, various inks have certain differences in the composition of components and the ability to express colors. From this point of view, the printer model used for ink is also different.

Now some printers in the market have been debugged by the manufacturer. The internal structure and drive are suitable for water-based inks and oil-based inks. However, once it is decided which ink to apply, it is better not to modify it, because there are already residual inks in the ink tubes and nozzles. If it is replaced, it will cause different inks to mix together, which will result in the printer nozzle not being able to eject ink and more serious damage to the machine.

So, if the printer user wants to change to oily ink after using water-based dye ink, is it feasible? In principle, this kind of operation is feasible. First of all, regardless of the model, if there is a phenomenon of wanting to replace the ink, the internal ink must be completely emptied. If there are conditions, it is better to replace the ink cartridge directly. Ink is more difficult to remove. Moreover, the ink in the ink tube should be completely cleaned, and the ink can be reversely washed first, the ink in the ink tube is completely returned to the ink cartridge, and then the cleaning liquid is driven into the ink tube, and the ink is cleaned after repeated cleaning. Eliminate it completely and use it again.

The printer nozzle is the most important part of the whole machine. If you change the ink used, the work of the nozzle is even more important. If you are using a sublimation printer, because the price of the nozzle is high, it is not recommended to replace the nozzle when replacing the corresponding dye sublimation ink. However, the nozzle must be removed and manually cleaned to completely remove the ink inside the nozzle. When using new ink, the mixing of the two inks causes the nozzle to clog.

Although some printers are suitable for both types of ink, it is best not to replace them once the user has selected the ink. Replacing the used ink is not only troublesome to operate, but also has many uncertainties. If there is a problem that the machine cannot be used after replacing the ink, it is really worth the loss.

Sublimation Digital Printer-Why Appearing Irregular Horizontal Stripes When Printing

In the printing process of sublimation digital printers, irregular horizontal stripes appear sometimes, mainly in the horizontal stripes that randomly change to magenta, smoky or yellow.

This problem may occur after the sublimation inkjet printer you just purchased has been used for a while, and the repaired printer may have this problem again after a period of use. The generation cycle of the problem varies slightly depending on the user's usage environment.

The cause of irregular stripes in dye-sublimation printer: Inkjet piezoelectric printers print abnormal stripes because the nozzle's board is subject to some degree of corrosion in a particular climate.

Solution:
If the inkjet head of the large format sublimation printer has been damaged and needs to be scrapped or repaired, a new inkjet head must be replaced. When installing a new nozzle, first protect the new inkjet head for repair and replacement (spray protective fluid to isolate the atmosphere) and install it on the printer to be repaired. This measure is effective in the actual test, and it can almost eliminate the rework caused by this fault.

Protection of the surface of the inkjet head:
Take a package with a slightly larger area (plastic bag, thick paper, etc.), open a hole with the same area as the nozzle part of the print head, and the print head should be basically free of gaps after it is placed (to prevent the mist-like protective liquid) Clogged the surface of the nozzle)

Ink hole protection:
Install the ink cartridge on the inkjet head to protect the ink filling hole.

What Causes Sublimation Transfer Printer To Be Heavily Color Cast?

Sublimation transfer printers sometimes appear different from the color of the computer. Why is there a color cast phenomenon? Our sublimation printer supplier here is a brief introduction to the reasons.

Five reasons for the color cast of large format sublimation printers


First, if you want to compare, you can't expect the printer to print the same color as the computer, because the display is RGB true color, its color gamut is wide, and the sublimation inkjet printer is CMYK false color, so the color gamut is narrow. The software automatic conversion mode will drop some colors, which is normal.
Generally, for this case, the solution is to adjust the color cast. The method is to reduce the amount of yellow in the Y channel, fine-tuning each time, and adjusting multiple times. Of course, you can also ask the master to help you adjust the curve, and save it after satisfaction, just spend some money, someone is responsible for adjusting the curve work.

Second, color distortion is also related to computer color management, display resolution, printer resolution, and print media.


Third, if you need to install 4 or more nozzles for the digital sublimation printer, please check if it is the same brand. Because the ink color of the same brand of printer has a good complementarity and coordination, thus ensuring the reproduction of its color.

Fourth, check if the printer nozzle is broken or if the large ink bottle is out of ink.

Fifth, please check if it is set to save ink or resume printing. Finally, before printing, please check the model of the map in photoshop is RGB or CMYK, when using the domestic printer to map the pattern to CMYK.
