Why Choose EPSON Printheads for DTF Printing

The printhead is one of the most important components of a DTF printer and is critical to the performance and quality of the print. Once the printhead is clogged or burned, it will have a great impact on the overall operating status of the machine. Most of the DTF printer manufacturers in the market today use EPSON printheads.

 

Why do I need to use EPSON printheads for DTF printing?

 

High-precision printing: Epson's micro-piezo printheads achieve superior positioning accuracy by controlling the curved liquid surface at the tip of each nozzle and utilizing Variable Size Dot Technology (VSDT), which rapidly ejects up to 50,000 ink drops per second. The curved surface control technology utilizes the movement of a precisely controlled piezoelectric element to control the curved surface. By quickly suppressing the residual vibration of the curved liquid surface, the mist generated by the residual vibration is suppressed, ensuring that large and small ink drops are sprayed straight, almost perfectly spherical, and land with superior placement accuracy.

 

Flexible droplet control: VSDT controls the volume of injected droplets by precisely controlling the voltage waveform driving the piezo element. Variable Size Dot Technology By precisely controlling the voltage waveform driving the piezoelectric element, the VSDT can control the volume of ink in the ejected drop. Drops as small as 1.5 picoliters (or trillionths of a liter) can be deposited in the exact amount and position required.

 

 

Supports fast output: Since each nozzle can selectively eject a range of drop sizes, users can enjoy fast output and beautiful image performance with virtually no graininess.

 

High durability: Micro piezo printheads are extremely durable because they do not suffer from heat-induced functional degradation. They are even compatible with inks whose material properties change when heated. Printers with piezo technology can use a wide range of inks, including dye and pigment inks.

 

EPSON printheads offer good performance and stability to meet the production demands of high resolution, durability and fast printing for high quality and efficient DTF printing.

Choosing the right printhead for your DTF printer

Choosing the right printhead for your DTF printer is an important decision and should not be taken lightly. There are many factors to consider when making your choices, such as the size of the print area, the type of material to be printed, and the cost of the printhead itself. The I3200-A1 is a robust and reliable choice for large-format DTF printing, while the I1600-A1 and XP600 offer more affordable options for smaller DTF printer. Ultimately, the decision depends on your printer needs and budget considerations. Each print head offers outstanding performance to help you create stunning prints.

 

How to maintain the DTF printhead?

 

Operation precautions
1. Without closing the power switch and cutting off the total power supply, do not randomly install or remove the digital printing machine's electronic components. Otherwise, it will damage the service life of each system and endanger the printhead.
2. Whether replacing or fine-tuning the printhead, do not use brute force, to replace or fine-tune the printhead following the specifications of the instrument manual.
3. Do not mix two different inks during printer operation. Different inks configuration of raw materials will vary. Two different inks mixed may cause chemical reactions that will directly affect the printing effect, or even lead to clogging of the nozzle.
4. Do not remove the printhead from the digital printing machine and leave it naked, especially in dusty places. Because the moisture contained in the ink will gradually evaporate, and the dry ink will lead to nozzle blockage. If the nozzle is blocked, it should be cleaned before use.
5. Nozzle cleaning fluid is corrosive, it is recommended to wash in moderation every time.

 

 

Cleaning precautions
1. Manual cleaning should be carried out in accordance with the steps in the operating requirements. Watch how to clean the nozzles>>
2. When cleaning, you can set a thin hose in the front of the medical syringe, filled with strictly filtered cleaning fluid rinse. Flushing with a magnifying glass to carefully observe the spray hole, if there is a residue of siltation next to the spray hole, use soft rubber products to remove it. The integrated print nozzles left unused for a long time will block the nozzle holes due to dry ink and can be cleaned with a particular cleaning solution.
3. Don't use sharp objects to clean the printhead, don't hit the printhead, and don't touch the printhead with your hands.
4. Don't disassemble or install the printhead while it is charged, and do not touch the electrical contacts on the printhead with your hands or other objects.
