 Four attention for UV inkjet printers in winter

UV printing

      Every year when the winter gets cold, the number of failures of UV inkjet printers will also increase, mainly in 4 aspects: print head blocked and disconnected, consumables solidify and condense, electrostatic interference, and unstable voltage. How to prevent these situations in advance.

     The matters needing attention are as follows

      1. Print head blocked and disconnected

     After the temperature is lowered in winter, the nozzle will appear “clogged and disconnected”, so don’t worry too much. This is mostly because the UV ink's viscosity increases and the fluency decrease after the temperature of the UV ink decreases. Smooth result.

      Solution: In addition to the conventional large ink cartridges and second-class ink cartridges that are automatically stirred and warmed, heating plates can be installed on both sides of the ink outlet of the print head. If it is not convenient to install, you can choose a small sun from a certain east and a certain treasure and keep it 30 cm The distance to the headlight car, if possible, you can turn on the heater or air conditioner to keep the working environment temperature of the UV printer above 25 degrees.

     2. consumables solidify and condense

   Some UV printer users found that the ink in the UV ink bottle became thick and some had condensed. When this happens, the ink has been discarded and cannot be used, mostly because the ink bottle is placed directly on the ground.

     Solution: The storage of winter consumables needs to be placed on the shelf, not on the ground, or placed in the open air.

3. electrostatic interference

   In winter, the wetlands of the air are reduced, and after the dust is increased, static electricity often occurs. The direct effect is that the ejected ink droplets deviate from the direction due to static electricity, causing "flying ink" or "splatter ink" phenomenon, and the print quality will be seriously reduced. In severe cases, the circuit will be burned.

    Solution: In addition to installing the necessary ground wire, the working environment of the UV printing machine needs to be maintained for 2 days / time to reduce dust. If the air is dry, just turn on the humidifier. If possible, an electrostatic rod can be installed on the machine to eliminate static interference from the material itself.

      4. Unstable voltage

    In winter, due to heating demand, a large number of electrical appliances will be turned on, and current and voltage will be overloaded. These instability, light will affect the normal operation of digital UV printer, and in other words, it will directly burn the internal circuit.

    Solution: In addition to selecting a regular manufacturer's UV printer (the circuit system has preventive and emergency resolution devices), a voltage regulator must be installed, a backup power supply must be installed, and independent lines must be installed for the device. It cannot be mixed with other electrical appliances.

Which is the right print side of the sublimation paper?

Which is the right print side of the sublimation paper?     Sublimation paper is one type of coated paper, and most of the sublimation transfer paper comes with right and wrong side for printing.if you print on wrong side, the transfer will not have best color,will result in a poor transfer which looks mottled and washed out, and you'll have to do it again. So dye sublimation paper can only be printed on one side (which is the release side). This article next will firtstly talking about the right printing side of the sheet (such as the A3 A4) sublimation paper.    Printing on the wrong side happens a lot in sheet sublimation paper . People always ask their supplier “which side to print", normally the answer is "the brighter side is the printing side", but for some people who have bad view , just like me, are incapable of telling the very small difference between two things, then we still have a big problem in identify the correct side. Today we will share

Is DTG Printing Eco-friendly?

 Is DTG Printing Eco-friendly?    DTG printing is a more sustainable fashion business model than screen printing. Mainly because printing one-offs allows businesses to avoid overproduction and textile waste. With 92 million tons of textile going to waste in the fashion industry each year, a business model like this is a game-changer.     Plus, a lot of DTG printer manufacturers create advanced tech that’s made with sustainability in mind. For example, our partners with Sublistar whose printers produce almost zero wastewater and use less energy, lowering the carbon footprint.     What’s more, sublistar DTG printers use water-based vegan inks that they formulate, test, and produce in their own ink factories, maintaining the highest quality levels. The inks are non-hazardous, toxin-free, biodegradable, and contain no animal by-products.     Direct-to-garment printing is a hassle-free way to get the products ready for your customers.    Most third-party printers have no order minimums for

The Sublimation Printing on Garment Industrial

  As one of the most important application field of sublimation printing , garment industrial plays an significant role in sublimation printing technology ’ s development. Why sublimation printing are used widely in garment industrial?    1. Good printing result   The garments printed by sublimation printing technology usually has beautiful patterns and vivid color. Besides, the layers of the patterns are rich and clear, so the images has a strong three-dimensional feeling.This is hard to achieve by other printing methods. What ’ s more, the sublimation printing can print the photographic pictures and paintings.    2. The garments are soft and the images have long service life   The biggest feature of sublimation transfer printing is the dye can be spread into the polyester or fiber, and the products feel very soft and comfortable. Because the sublimation ink has been dry in the transfer process, the life of the images are the same as the life of the garment itself,
