UV printing is one of the most flexible and exciting print processes ever created, and its uses are almost limitless. This article will help you explore this novel UV printing technology, learn how it works, and get inspired about what you can create with it.
What is UV printing?
UV printing is a printing technique that uses ultraviolet light to cure or dry ink, coatings, adhesives, and acrylic. This technology allows you to print onto a wide variety of non-traditional materials.
Do I need UV printing?
UV printing can work with a variety of media and artifacts, such as gadgets, gifts, signage, clothing, electronics, ceramics, jewelry, and homeware.
Delivering outstanding print quality that your consumers demand
UV printing is an ideal solution that makes product customizations easier and faster. It can produce complex textures on the surfaces of a wide spectrum of products, from bottles to pens, to smartphone cases and USB memory sticks. UV printers typically offer white and clear ink (matt and gloss varnish) that work with the standard CMYK color gamut to create vibrant colors and outstanding gloss, matt, textured, and 3D effects on a vast array of substrates.
UV printing has rapidly become an essential tool for sign makers, graphic providers, advertising agencies and designers, and retailers. UV allows printing onto a breath-taking array of surfaces and shapes.
Even those who already have screen and pad printing as part of their skill set are enjoying a healthy return from the liberating simplicity, speed, and cost-effectiveness of UV digital printing in addition to their existing daily workflow.
In addition, UV printing can be easily placed into copy shops, printing centers, and shops to offer customized and highly profitable products . The question is not whether you should invest in a UV printer – it’s more of a case of how much you should invest and what printer model best suits your needs.
How UV printing works?
UV digital printing provides a fast printing process by instantly curing specially formulated UV inks on a vast range of materials using UV light. Let’s see the three elements that produce the final work.
Print heads
High-precision ink placement is delivered using piezo print head technology, in which microscopic piezoelectric elements (such as crystals and ceramics) are mounted behind the print head nozzles.
When an electrical charge is applied, these elements flex, ejecting precise quantities of ink onto the print medium.
This technology provides an exquisite degree of control over the machine’s ink pumping while also creating perfectly spherical droplets in different sizes for extraordinary control over print quality, color density, and finish.
Therefore, you will notice amazing print quality, and so will your customers.
UV inks
The ink is instantly cured during the printing process, and there’s no need for degassing or drying.
An object can be printed and immediately used for its intended application, or the printed substrate – for example, cardboard for a packaging prototype – can be taken straight from the printer to the cutter without any risk of the ink chipping or cracking.
UV ink is normally flexible so that it can follow curves or print on an elastic medium.
UV light
The built-in UV lamp emits only UV-A light. This component is cost-effective and does not require warm-up to cure the ink, saving both time and energy.
Such lamps allow the UV printer to print on heat sensitive materials, including shrink wrap, natural wood, and screen protection films (for the proection of smartphone or tablet screens).
