This ability enables you to utilize the UV printing device to create unique outcomes, such as 3D effects and raised images. The UV-LED curing system also means you can enjoy faster operating speeds with a UV printer since the LED lamps dry the printed ink drops instantly.

Aside from these, you can find it challenging to work on such substrates when using a sublimation printer. In contrast, a UV printer uses CMYK ink with clear and white inks to make printing on a dark or clear background more comfortable. When printing on a dark or clear surface, you can use white ink to create a base coat beneath the color graphic. In addition, you can utilize the clear ink component to form a clear coat over your image and generate a glossy look with enhanced durability.

Although you can use both machines without color limitations, a sublimation printer can only function on 100-percent polyester materials. You can also utilize the machine on hard objects such as mugs coated with a clear and long-lasting polyester layer. Conversely, a UV printer allows you to print on almost any material without primer or coating.

Why Should You Maintain UV Printer?

As with every machine, regular maintenance is necessary to ensure your UV printer continuously functions well (9). If you have a car and do not take it to regular servicing, you can expect it to break down and cause total failure. Similarly, poorly caring for a UV printing device means you expose it to minor failures that eventually build up to a catastrophic failure.

You need to begin by understanding your machine well to ensure you can properly care for it. For example, you should know facts about your UV printer, such as its maximum head gap and the maximum distance you can have between the substrate and print head.

Knowing these points lets you avoid unnecessary messes since exceeding the maximum head gap causes the device to generate excessive ink misting. This excessive mist causes parts to fail because it sticks to everything, leading to costly repairs.

Furthermore, understanding your machine lets you know the modifications needed for quality printing, such as incorporating a jig when working off an object’s edge, such as a phone case.

Placing the jig between the phone cases keeps UV light from reflecting on the print heads while simultaneously catching excessive ink. When you fail to control the light, it bounces around the jigs, resulting in excessive light that causes nozzle loss and damages the print heads.  

Your maintenance schedule often relies on the products you print, with a good rule of thumb dictating maintenance after every 8-hour cycle. Cylindrical, tapered, and rounded objects may generate more ink mist, needing more frequent maintenance checks.

The UV printer includes manufacturer guidelines in its package that you can conveniently depend on for proper and safe maintenance procedures. It is best to follow the provided instructions, including using only the prescribed chemicals in the guidelines.
