The most feared thing for paint digital printing machines is printhead blockage, which causes many "complications" such as oblique spraying, flying ink, and deflected needles, which will shorten the life of the printheads. In severe cases, the printheads may even be scrapped, seriously affecting the production progress.
So we need to understand the reasons for printhead blockage and how to prevent printhead blockage in paint digital printing machines.
01 Choose high-quality and stable pigment ink , It is the key to ensuring smooth printing
Poor quality ink raw materials uses poor quality, large particles, and many impurities, which can easily block the printhead and cause digital printing machines to print with broken lines, color defects, etc. Therefore, it is recommended that choose high-quality ink , preferably original ink from the manufacturer, guaranteed quality and better compatibility with the equipment.
PO-TRY Pigment Ink
PO-TRY's independently developed pigment ink uses high-quality raw materials and has good stability, adhesion, corrosion resistance, and wear resistance. It is not easy to block the printhead and has a wide color gamut, with bright and rich colors and excellent color expression.
02 The equipment should have complete and reliable , Ink Road and Moisturizing System
The concentration of pigment ink is high,If the printhead long time does not work or is exposed to the air for long time, the ink will dry easily and block the printhead. Therefore, the reliability of the digital printing machine moisturizing system is very important. During work, the operator needs to ensure that the printhead is always moisturized.
In addition, when the sudden power outage causes the printhead group to fail to return to its original position in time, and when the printhead group needs to be removed from the ink cup during equipment maintenance, the printhead must be sealed and moisturized.
03 Maintain working environment , Appropriate temperature and humidity
Recently, the weather in China has been erratic, with heavy rainfall and rapid temperature changes. The best working environment for a printing machine is 20°C-28°C and 40%-60% humidity.
High and low temperatures affect the viscosity of the ink, thus breaking the original state of the ink, causing frequent line breaks and even scattered images during the printing process.
If the ambient humidity is too low and the temperature is relatively high, the volatility of the ink will increase, and the ink will easily dry and form solids on the surface of the printhead, affecting the normal operation of the inkjet printing machine printhead. If the humidity is too high, the ink may accumulate around the printhead hole, which will also affect the operation of the printhead, and the image will not dry easily.
Therefore, manufacturers should maintain a suitable temperature and humidity in the working environment to extend the service life of the printhead and the machine.
PO-TRY recently launched a 3-head dual-station T-shirt direct-injection printer, which provides a paint digital printing direct-injection solution that can maintain high-speed and high-precision printing effects. At the same time, it adopts high-quality configurations that can effectively prevent printhead blockage and achieve stable printing.

04 Digital printing machine operation should be standardized , Pay attention to daily maintenance of the machine
First of all, the equipment provider should provide detailed training to the operators of the digital printing factory, including equipment operation methods, shutdown maintenance procedures, etc. The equipment operators should strictly follow the maintenance requirements of the equipment manufacturers and ink manufacturers to perform daily maintenance to reduce the chance of blockage caused by the operator's incorrect operation.
Secondly, the factory operators should operate in a standardized manner. Before each start-up, they must print a test strip to test the printing condition of the printhead to ensure that the ink is complete. If there is no problem, normal production can be carried out.
PO-TRY has been focusing on the research and development, production and sales of digital printing equipment and inkjet consumables for 14 years. have professional after-sales technical team to provide customers with lifelong after-sales and installation training, one-stop empowerment services, worry-free after-sales, and help customers improve production efficiency and business competitiveness.
