HOLDWIN-620 Pro UV

The 620 Pro UV Printer is a specialized roll-to-roll UV DTF (Direct-to-Film) system designed for high-speed, high-precision custom labeling and decoration on a wide variety of hard surfaces.

It is often branded as a “Crystal Label Printer” due to the durable, sticker-like quality of the final transfer.

How Does UV Printing Work?

Piezoelectric Print Head

This is the part that sprays the ink. It moves precisely over the surface and shoots out tiny droplets of ink.

Unlike regular inkjet heads, it is designed to handle thicker, pigment-rich UV inks. The print head controls how much ink is placed and where, allowing for sharp, detailed images.

UV Lamp

The UV lamp emits ultraviolet light that cures the ink. Most UV printers use LED lamps because they are energy-efficient and last a long time.

UV Ink

UV ink is made to react to ultraviolet light. It usually comes in CMYK colors, which are cyan, magenta, yellow, and black. CMYK is the standard for printing.

This UV printer significantly streamlines production by printing directly onto specialized UV film (AB crystal film). This innovative process allows the printed film to be transferred directly onto substrates without any extra adhesive or laminating step.

Here is how it all comes together on the surface:

• The print head sprays UV ink droplets with precision.
• The UV lamp shines ultraviolet light to cure the ink immediately.
• Because the ink cures instantly, the print is bright, sharp, and long-lasting.
