How To Solve The UV Printer Failure In Winter?

UV printing

When it gets cold in winter every year, the number of failures of UV printers will also increase, mainly in four areas: print head nozzle blockage and disconnection, consumables solidification and condensation, electrostatic interference, and voltage instability. In view of these situations, how to prevent them in advance.

1. Print head nozzle blockage and disconnection. After the temperature drops in winter, the print head will be “clogged or disconnected”. Don’t worry too much. This is mostly because the viscosity of the UV ink increases and the fluency of the ink decreases after the temperature drops. Individual nozzles do not emit ink smoothly.

Solution: In addition to the automatic stirring and heating of conventional large ink cartridges and secondary ink cartridges, heating plates can be installed on both sides of the ink outlet of the nozzle. If it is not convenient to install, you can choose a small sun and keep 30cm Distance, illuminate the head car, if possible, you can turn on the heating or air conditioning to keep the working environment temperature of the UV printer above 25 degrees.

2. Consumables solidification and condensation. Users of UV printers found that the ink in the UV ink bottle has become viscous, and some of it has condensed. When this happens, it means that the ink has been scrapped and cannot be used, mostly because the ink bottle is placed directly on the ground.

Solution: The storage of consumables in winter must be placed on the shelf, not on the ground, and not in the open air.

The direct effect is that the ejected ink droplets deviate from the direction due to static electricity, causing the phenomenon of “flying ink” or “ink splashing”, and the print quality will be seriously reduced. In severe cases, it will cause the circuit to burn down.

Solution: In addition to installing the necessary ground wire, the cleaning of the working environment of the UV printer requires 2 days/time for maintenance 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 the electrostatic interference of the material itself.

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

Solution: In addition to choosing a UV inkjet printer from a regular manufacturer (the circuit system has preventive and emergency solutions), a voltage stabilizer must be installed, a backup power supply and a separate line for the equipment must be installed. It cannot be mixed with other electrical appliances.

The Differences Between UV and UV LED Printer

UV printer also can distinguish into these 2 kinds in aspects: UV printer and UV LED printer. UV-LED is different from UV in a number of important ways. Let’s have a look.

Many UV-LED printers support a broad array of substrates, including everything from PVC, leather, paper and board stocks, to foils, BOPP, PE, and PET film.

When it comes to specialty applications, most compact UV-LED printers print directly on three-dimensional objects, such as smartphone cases, industrial and consumer products, promotional items and even iPads.

The difference between the two technologies is obvious and comes down to how the ink is cured. UV-LED uses a low-energy light source, and the lamps are expected to last the life of the press.

Another difference shows up in cost. The cost of lamps is lower in UV than in UV-LED. As that cost differential drops, UV-LED will continue to make inroads in faster presses, even in industrial applications. A final contrast between the two technologies is that UV-LED is a greener solution, due to not requiring as many bulbs to be replaced and lower energy usage.

The big difference is the curing power, as well as the light spectrum, is given off by the machine. UV machines have broader curing power.

The traditional UV bulb has a broader light spectrum, while UV-LED has a tight and more controlled spectrum. What that means is more curing power out of the traditional UV, rather than the UV-LED. The UV-LED is almost like a straight line, a more confined space, as opposed to the traditional UV lamp, which has a broader and deeper curing power.

Okay, these all above are my share about difference betweeen UV printer and UV LED printer. If you have any other needs or questions welcome to contact us at any time. We will provide you the best quality product and service. Thanks for your reading.

The Difference Between Flatbed Printer And UV Printer

Category : Blog

How much do you know about flatbed printer and UV printer? Today, I will introduce the difference between them.

UV Printer:

Different from flatbed printers, UV printers are a technology-free full-color digital printing machine without material restrictions. It can be used on T-shirts, sliding doors, cabinet doors, sliding doors, glass, plates, various signs, crystals, PVC, Color photo-level printing on acrylic, metal, plastic, stone, leather and other surfaces.

UV printers have a wide range of printing materials, flexible media such as: timely posting, PVC, reflective film, canvas, carpet, leather, etc.; rigid media such as: glass, ceramic tiles, metal, ceiling, aluminum, wood, door, acrylic, plexiglass , Foam board, corrugated cardboard, etc.

Flatbed Printer:

Flatbed printer is a kind of equipment that can perform color photo-level printing on wood, glass, crystal, PVC, ABS, acrylic, metal, plastic, stone, leather, cloth and other textile surfaces. Flatbed printers print patterns. Its printing method is inkjet printing, and there is no actual contact with the object during the printing process.

Flatbed printers are not restricted by any material. Whether it is a simple block color pattern, a full-color pattern or a pattern with excessive colors, it can be printed at one time, without plate making, printing and repeated color registration, and its application fields are very wide.
