UV Printing on Glass UV print technology:

It may sound like the wave of the future, but it’s actually been around for at least the past 10 years.

Unlike traditional inks that dry by soaking into the substrate and evaporating in the air, UV LED inks dry when they’re exposed to ultraviolet light. Not only is the end result crisper and cleaner, but it is also much more versatile. UV printing can work on a wide variety of different substrates that go far beyond plain old paper.

Old-school UV printers may have been exceedingly large and expensive. But technological developments have made cutting-edge UV printer in both size and price. A small-format flatbed printer can easily fit right on your desktop, ready for any action you send its way. And there’s plenty of action you can give it.

An immense array of commercial and industrial applications can easily become a reality with the use of a UV printer. It can print the same photos, logos, text, illustrations, diagrams or other images as a standard printer. But with a higher-quality, durable, UV-resistant end product that is less prone to chipping, flaking and fading.

Metal: Print directly onto stainless steel, aluminum and powder-coated metal to create custom military, aviation and commercial name plates, dog tags or identification plates and dials for industrial parts and equipment. More uses on metal include full-color, high-contrast marks on face plates, microchips and dial faces.

UV LED Printing Plastic and PVC: Name badges and photo IDs are a breeze with a UV printing machine, as are luggage tags, ID bracelets, book covers and injection-molded parts that need labeling. Printing directly onto to phone cases is a snap.

Vinyl: Electronics skins are hot vinyl products, and you can also print on vinyl stickers, tablet or laptop cases.

Glass: Put your UV printer to work creating glass artwork, including cylindrical wine glasses with the EasyCyl attachment, trophies and customized, full-color mirrors.

Ceramic tiles: Whether used for hot plates, decoration or signage, personalized ceramic tiles are well-suited for UV printer application.

Signs: Print up vinyl, plastic or metal signs for outdoor or indoor use. Showcase your company name and special sales or create your own door signs. Enhance profits with special applications like ADA/Braille-compliant signage.

Plaques and awards: Whether you need to print directly onto wood, acrylic or an award’s metal plate, a UV printing machine can easily do the job.

Promotional items: The world of substrates is wide open for printing on an array of promotional items. Customize non-flat items like golf balls, rubber items like hockey pucks. And other giveaways such as tape measures, key chains, magnets and flash drives.

TEXTUR 3D Printing: Make a stunning statement with 3-dimensional, textured printing on signage, tablet cases, wall hangings, prints and other items. They deserve eye-catching, artistic results. A UV printer can also print braille.

OCR applications: UV printers retain the finest details, ideal for OCR applications that require scanning.

Basic black anything: Their high-end technology have helped UV printers enhance the printing performance of opaque white ink, opening the door for high-impact printing on black and other dark backgrounds and materials.

Solvent UV Ink: What Is It And When Should It Be Used?

Nessan Cleary investigates the pros and cons of Solvent UV ink, the hybrid answer to tricky digital printing challenges.

Solvent UV inks combine the best elements of solvent and UV technology to overcome the weaknesses in each type of ink.

There are a number of different types of ink that are commonly used for wide format. Most are mature technologies that have been around for a while and are easily understood. So, we think of solvent inks as being relatively inexpensive and best used for flexible materials. While UV inks will adhere well to a wide range of substrates and are mainly used with rigid media.

But ink developers are constantly looking at new formulations. So it shouldn’t be a surprise. There is now a hybrid that combines solvent and UV inks, promising the best features of both.

Solvent UV Ink: What Is It And When Should It Be Used?

The concept has been largely popularised by Mimaki, which refers to this technology as Solvent UV. Mimaki has developed a roll-fed printer, the JV400 SUV, which is built on the same chassis as the JV400 LX latex printer. Thus it has inherited two Ricoh printheads, with resolution from 600 to 1200 dpi and a standard speed of 18.1 sqm/hr. It has a standard three way drying system, similar to any solvent printer, plus a fluorescent tube for UV curing. It’s available in two sizes – 1371mm and 1620mm.

Tudor Morgan, systems marketing specialist, explains: “We try to incorporate the best of both types of chemistry. UV is very good for curing fast. It’s got a wide adhesive range but with conventional UV you end up with a high ink film but in some applications people want a low film weight so that it looks more photographic. So we use a solvent carrier that evaporates out of the film which then means that the film becomes thinner.”

Effectively, the solvent is replacing the monomer component of a standard UV ink, and keying the UV elements into the media, much as with a solvent ink. The solvent itself is water-based, so there are no harmful VOCs and no need for ventilation.

Mike Horsten, marketing manager for Mimaki Europe. He says that the big advantage is  any laminating needed can be done immediately. Because you don’t have to wait for it to de-gas. Though he adds: “If you want to do a car wrap for three months and don’t want to use an extra layer of laminate then it becomes viable.”

The downside is the cost, with these inks being more expensive than a solvent ink. And it ismuch closer in price to a UV ink. Though as with UV inks, the ink consumption should be lower than a solvent ink. But it’s really the solvent market where this system aims to compete. Horsten adds: “We do assume that there’s a move from solvent to SUV because you have the benefits of both. It’s dried fully but it still has the glossy image.”

Morgan adds: “Profiling is much easier because we have the UV consistency.” That said, there’s no option to use rigid media with these printers as they would need a substantial redesign to accommodate the UV curing lamp on the media path.

The Lightbar

There is a third player in this solvent UV ink game – Colorific – which has developed a range of UV Light inks. There’s up to six colours – CMYK plus light cyan and light magenta. But rather than develop a specific printer, Colorific has opted to adapt existing solvent printers. Adding a fluorescent lighting unit, it calls the Lightbar, across the front to activate the UV curing. This is held in place by brackets attached to the printer’s legs, so that as the prints exit the printer they pass under the Lightbar for curing and then onto the take up rollers.

Customers can buy either a complete printer or a kit to adapt their own printers, which is a useful way of rejuvenating an older printer that’s outlived its warranty. It works with Epson DX4, DX5 and DX7 printheads, which includes Roland, Mimaki and Mutoh printers. They use those heads, giving a fair range of different sizes and capabilities to choose from, including print and cut machines as well as straightforward printers. It also means that customers can get many of the advantages of a roll-fed UV printer for very little additional outlay.

Ultimately these printers offer a saving on time and laminate, as well as brighter colours and a glossy finish. These are all useful features and many wide format users may find these printers a worthwhile addition to their portfolio.
