UV Printer – Two Features to Look for With Almost Any UV Printer.

Small format coffee printer have distinct character and variety of special applications of their very own in a fashion that you don't see with, say, the narrowest versions of solvent roll fed printers.

The compact size of the littlest A3 bed models means they'll fit into places the place you wouldn't put a large format printer, along with the relatively low entry prices suggest that they're attracting the sort of user that can't accommodate or simply can't afford a "conventional" flatbed.

In the same way more importantly, these baby flatbeds are made to adopt deep, often three dimensional objects which are situated on the beds by vacuum and jigs.

This materials handling ability above all else is driving the applications, which include objects such as phone and tablet cases, laptop lids, leather folder, book and iPad covers, pens, USB sticks, golf balls, plaques, ceramic tiles and plates, trophies and office nameplates. For additional industrial purposes, the printers can be used for backlit instrument panels, touch switch panels, component marking and so on.

They will likely print on anything that's relatively small and solid, really. Most of these small printers use UV-cured inks, which sticks to numerous surfaces, while some (including Mimaki) can optionally print a primer fluid that increases the plethora of substrates that may be handled. Copytrax offers both strong solvent and water-based gel inks as well as UV curing.

Modest curves can be printed on, but not anything by using a significant variation in height because the accurate "throw distance" of your ink droplets is comparatively small, as with any inkjet. As an example golf balls is only able to be printed in a fairly small circle round the highest point, instead of the complete of just one hemisphere.

All this class of small flatbeds have vacuum beds, however if you're printing multiple small 3D objects you'll want a jig to hold them in predetermined positions, so the printed image is applied to the right areas. Jigs can be produced from wood, foam, metal or Perspex.

The jig is connected to the design system or Rip through simple templates that position the artwork objects to align using the physical jigs. Mimaki demonstrated a jig-free camera based position locator and automatic registration system at drupa 2012, but hasn't released it as a a production system to date.

The FESPA Digital event in Munich this season saw the most recent arrival to the baby flatbed party. Mutoh announced its ValueJet 426UF, a keenly priced A3 flatbed printer that fills a gap in its range where it couldn't previously contend with its fellow Japanese rivals Mimaki and Roland DG.

This new model is a result of ship in September 2014 and we'll look at it in more detail partly two, together with the equally interesting products available from several of the smaller European developers: Copytrax/Azon and Bergstein.

This Mimaki UJF-3042FX includes a jig on its bed to position small gift items - in this case paper cutters.

Actually Mutoh has come rather late to the party. Mimaki announced its first A3 flatbed, the UJF-3042, five-years ago and possesses since revised it with a couple of variations along with an A2 version. Mimaki itself wasn't the first one to build a4 uv printer, because there was attempts to get small solvent flatbeds above the ground in the early 2000s.

However, Mimaki's combination of UV inks and LED curing lamps by using a deep adjustable-height bed, in conjunction with its marketing clout, made the UJF-3042 a quick sales success. Priced below €30,000, these printers sold as quickly as Mimaki may make them to the first year or two.

The original UJF-3042 was revised and renamed UJF-3042FX in 2011. It requires items as much as 50 mm thick and now costs about €21,500 (a drop of approximately 25% since launch)). This Year it was actually joined by the €38,000 UJF-3042HG, which can accept 150 mm deep objects. An A2 format UJF-6042 was introduced in 2012, for about €50,000.

All models print a maximum of 1,800 dpi and offer CMYK plus light cyan and light magenta and may optionally print a primer coating if needed.

The initial UJF-3042 prints either white or clear ink, as the other two can run both in a similar unit. There's a choice of high durability, stretchable or wide gamut inks, and the white has recirculation.

In accordance with Mimaki, the UJF-6042 can print a complete bed between 2 minutes thirty seconds and 7 minutes 37 seconds according to the quality settings.

Kebab fits about the deeper beds of your Mimaki UJF-3042HG and also the UJF-6042 and includes motors to rotate cylindrical items.

In many markets Mimaki offers optional "Kebab" holders for the deep-bed UJF-3043HG and UJF-6042 that could rotate cylindrical objects such as wine bottles, candles or cardboard tubes beneath the heads. Cost is about €3,800 and it takes objects from 10 to 110mm diameter and up to 330 mm long.

Foiled metallic effects are loved by personalised giftware, but none of the small flatbeds have metallic inks yet. However at the end of last year I-Sub Digital, a UK based Mimaki dealer, launched Digi-Foil, a variety of metallic and decorative foils which have been specially developed for use with the UJF-3042 and 6042 models.

This works with a heated applicator for the largely manual process after initial printing. An exclusive adhesive ink can be used inside the printer like a separate pass, allowing prototypes, one-offs and short runs of foiled try to be produced without the need for hot foil dies and presses. I-Sub states that the foiled area might be anything "to dexmpky56 single dot."

Roland DG's first small UV flatbed was small indeed. The VersaUV LEF-12 has a A4 printing area. It had been initially priced at little below the greater Mimaki UJF-3042 models, which limited its appeal despite some nice features like a sealed lid and optional carbon filter to lower dust and ink mist.

Roland fixed that in 2013 by launching the SRA3 format LEF-20 at a cost that briefly undercut the Mimaki at about €25,000, while reducing the LEF-12's price considerably: throughout the uk it is now the same in principle as €16,400.

The LEF-20 takes objects up to 100 mm high. It gives you CMYK plus white and clear ink, in 220ml cartridges. With both the Roland models there's a choice of matt or gloss finish when curing the clear coating.

By using a maximum 1,440 dpi resolution in the LEF-20, Roland says it takes 7 minutes 20 seconds to print an entire SRA3 bed with CMYK only; or 12 minutes 44 seconds with CMYK plus white; and 17 minutes 20 seconds with CMYK white clear.

In Part 2 we'll have a look at further options in the dtg printer, as well as a take a look at where they fit alongside existing analogue and alternative digital processes.
