The Differences Between Sublimation Printer and Uv Printer

What’s the differences between uv printer and sublimation printer, there are three tips for pay attention.

sublimation printer First, use different ink
Thermal transfer printing uses thermal transfer ink, also known as thermal sublimation ink; uv printer uses uv ink.

Second, the process is different
Sublimation transfer: sublimation transfer printer is to first print the color pattern on a heat-resistant substrate, usually with a film material, and also need to be subjected to release treatment, and then combined with a special transfer device to transfer the pattern to the hot stamping method. Product surface. Thermal transfer needs to be equipped with a heat transfer machine, a baking machine, a baking cup machine, etc., and different products need to be processed.

The UV printer directly prints the favorite pattern directly on the surface of the product, essentially a type of piezoelectric inkjet printing device. The ultraviolet light emitted by the led cold light source lamp reacts with the photosensitive curing agent in the uv ink, causing the pigment molecules in the uv ink to solidify on the surface of the material.

Third, the application industry difference:
Sublimation transfer printer is currently used in plastics, toys, electrical appliances, gifts, food packaging, clothing and other industries. The advantage is that you can print on curved surfaces and irregular surfaces.

UV printers are mainly used in mobile phone cases, ceramic tiles, glass, metal, building materials, advertising, leather and many other industries. The advantage lies in the availability of the right, easy to operate, can achieve instant, batch production.

Why does the sublimation inkjet printer’s printhead “strike”?

The printhead is the heart of a wide-format inkjet printer. If there is a problem with the printhead, the entire machine will not work properly. Therefore, be sure to protect the print head when using the printer. So what conditions will affect the normal use of the print head? Today, I will come to give you a glimpse!


First, the airtightness between the ink cartridge, the ink tube, and the printhead.

I have previously talked about the inkjet principle of inkjet printers. Everyone knows that the printer printhead is controlled by the microvoltage change of the negative pressure system to control the ink output. To make the nozzle smoothly ink, it is necessary to ensure the inkjet system. Absolutely sealed. When the voltage is increased, the pressure of the micro-voltage to the ink tube will increase, and a pressure difference will be formed inside and outside the ink tube, and the ink will be pressed from the ink cartridge into the ink tube to the print head. If the inkjet system leaks, the negative pressure system can’t play its due role. If the ink can’t reach the print head, the print head will naturally not emit ink!

Second, the ink cartridge is leaking.

A small amount of air is always present in the upper part of the print cartridge connected to the continuous ink supply system, in order to avoid the phenomenon of ink self-flow caused by the siphon principle. However, if there is an air section in the entire inking line, it is caused by the air leakage of the ink cartridge or the unsealing of the ink injection elbow interface, so the air leakage of the ink cartridge may cause the ink to be discharged or the ink drop.

Third, improper operation.

The ink from the print head ejects ink through its orifice. Since this orifice is small, it may be clogged or damaged with carelessness.

During the printing process, some materials have poor adhesion, and we use a fixing agent to enhance their adhesion. Fixing agent is a very viscous solvent. Once it sticks to the nozzle, the nozzle will be blocked or directly scrapped, which will not work properly.

Fourth, the impact of external factors.

For example, when carrying or using a printer, the machine is hit by an external force, causing the printer to not work properly.



1. When using the sublimation inkjet printer, remember to follow the printer instructions strictly!

2. When the printer can’t print normally, don’t panic. Check carefully whether the printer spare parts are in good condition and make other judgments!

Why does the ink sublimation printer produce waste ink when it is used?

ink sublimation printerThe situation in which the ink sublimation printer generates a large amount of waste ink during the printing process is mainly concentrated on an inkjet printer using a split design. The main reason is that the printer uses a split structure. Since only the ink cartridge needs to be replaced, the joint between the print head and the ink cartridge is easy to enter the air, and the air entering from the print head can easily “support” the hole which is thinner than the hair thread, so that the ink cannot be unblocked, resulting in printing. Broken line phenomenon. Printing after a broken line will cause the text to be missing, the picture to have horizontal stripes and severe white lines. At the same time, in order to meet the needs of high-speed printing, the current inks are all fast-drying type. The long-term use of the ink sublimation printer and the drying of the air, etc., cause the residual ink on the nozzle to condense and cause the disconnection in the printing.

ink sublimation printerIn order to solve problems such as print breaks and unclear writing, all sublimation inkjet printers are equipped with a hardware system for ink cleaning and nozzle maintenance on the far right side of the machine. The inside of the printer is equipped with a rubber-made rubber scraper, which scrapes off the dirt attached to the nozzle surface with a rubber scraper. At the same time, after the printer stops printing, the ink cart automatically returns to the “nozzle protection seat”, and the sealing function of the “nozzle protection seat” is used to implement a short-term sealing to prevent the ink dryness of the nozzle from clogging the print head.

ink sublimation printer

For split-type models that are prone to wire breakage, manufacturers have adopted a more comprehensive printhead cleaning and dredging system. That is, under the “nozzle protection seat”, there is a pump accessory for cleaning the print head. By periodically extracting the ink in the ink cartridge, each ink passes through the nozzle hole, and finally the nozzle is sprayed out to achieve the purpose of unblocking the pipeline. These inks of various colors ejected from the nozzles are finally mixed together to become waste ink. This is the whole process of cleaning the print head, which many people refer to as “shampoo”. The waste ink generated by the “shampoo” has to be stored in a place, so the manufacturer set up a separate plate in the lower part of the wide format sublimation printer, called the waste ink tank (also called waste ink tray). The waste ink of the “shamp” is directly piped into the waste ink tank below the printer.

The integrated sublimation printer replaces the ink cartridge and replaces the nozzle, so there is no pump attachment and there is no ink cleaning. It produces very little waste ink. The waste ink tank is under the “nozzle protection seat”. The residual ink scraped by the rubber scraper in the waste ink tank will be tied into the waste ink tank over time. The split type waste ink is large in volume, and the volume of the waste ink tank is also large. At the same time, a cotton felt is placed in the waste ink tank to adsorb the waste ink.

What is the correct way to replace the motor part of a heat sublimation printer?

heat sublimation printerPeople who have used heat sublimation printers know that the motor is the core component of the power of the sublimation printer. Whether the large format sublimation printer can operate normally or not, the quality of the motor plays a very important role. Moreover, the use time of the motor is relatively long and generally difficult to damage. Therefore, before replacing the motor of this heat sublimation printer, the staff must first determine whether the motor is really damaged, or other components are faulty. At this time, people need to open the cover of the machine to see if the motor is running normally. The reason is that the problem of the conveyor belt damage and the gear bite can also cause problems in the car and the paper can not go down.

1. Steps to replace the heat sublimation printer motor

heat sublimation printerBefore you replace the motor for the digital sublimation printer, be sure to turn off the power. Use a screwdriver to remove the cover of the inkjet printer, remove the connecting wires of the motor, and remember to pick it up before unplugging the connecting wires. Otherwise, if the wrong interface is connected, it may cause the motor to burn directly, or the motherboard may be damaged directly.

Take the printer motor belt directly off, and pay special attention when removing it. The strength of the belt should not be too large, otherwise it will directly cause damage to the motor. Take the old motor of the printer directly and replace it with a new one.

2. Precautions for replacing the inkjet printer motor

People need to pay special attention when replacing the sublimation paper printer motor. The whole process of replacement can be completed with a screwdriver. Note that you cannot use a hammer or other tools to tap. Since the photo machine is a precision instrument, if it is subjected to an external impact, it may cause a second damage to the sublimation plotter in the future.

What should I do if the sublimation paper printer has a vertical line during the printing process?

sublimation paper printerSublimation printers will also experience many of the same problems as inkjet printers during long periods of use. For example, when the sublimation paper printer prints out and prints, the image quality is not good, and the vertical line in the print screen of the sublimation paper printer is a common problem.

A flashing line like a test strip that appears in the middle of the screen when printed, with two colors or a lot of messy strips appearing together. How to solve this problem? There is no fixed position of the flashing line, which appears randomly, and flashing lines appear in many places when the screen is printed.

Solve this fault according to different problem points. For vertical inkjet printers where vertical lines appear in the printed picture, the problem is largely on the raster. You can carefully check the grating to check if it is dirty or if the ink drops are stuck on it or if it is scratched. Then clean up and replace the test to solve, there are some ways to help you solve the problem.


sublimation paper printer1. Check the height of the grating decoder from the grating. The upper edge of the grating is preferably 1mm-1.5mm away from the decoder.

2. Wipe in the grating where the vertical line is located, and wipe it with pure cotton with medical cotton.

3. If the above two conditions are invalid, please re-plug the print head data cable, the car board and the motherboard cable.

4. If the above three conditions are invalid, please replace the motherboard or the car board.

I believe that the above steps can perfectly solve the vertical line problem in the textile sublimation printer printing screen.
