There are the flagship names which have for a long time taken the lead in both sales and technology, but as we start to move deeper in the 2000’s there are a number of companies that may not immediately be on your list, yet have racked up both experience and reputation. One of these companies is Mutoh, a Japanese manufacturer which has been providing high-quality and cutting-edge printers for over seventy years. Mutoh Europe, based in Oostende, Belgium, has been capably placed to provide support to EMEA clients and users. The list of digital printers available from Mutoh is both long and wide – whether it is LED UV, water-based UV, dye sublimation, or all types of sign and banner printing, they will have a high quality printer to suit your requirements. We choose to look a little deeper into the recent addition of the Mutoh XpertJet 1682UR which is the result of a root and branch review of the successful ValueJet 1638UR. This new machine has a number of updated and new features making it both quicker and more capable of providing wider and richer printed products. The machine is a reel fed digital printer reaching up to 1625mm in width, with a maximum printable width of 1615mm which can be used to print a number of products from signage, product mock ups, POD materials, and virtually any output you can think of from a reel. Providing the Colour The method of producing deep and rich coloured products is centred on a printhead with two eight channels of staggered nozzles, each containing 1440 heads. The combination of channels and nozzles can be configured to produce a variation of ink laydown. You can request the XpertJet 1682UR to produce CYMK on both tracks giving you the four process colours twice and this will deploy at up to 26.5m2/hr; the highest of production levels from the printer. You can also print with a combination of white ink and varnish, being five colours including white or up to six being the process set, white plus the varnish. This combination of colours and varnish gives an almost limitless combination of product when printing on clear, white, black, or front or back lit substrates. But what Mutoh would say gives them the extra component in the quality scale is the ability of the XpertJet 1682UR to print up to five levels in one pass. Colour lay down can be varied due to the 1440 nozzles being doubled into two banks each containing eight channels. This means you can have a combination of two times CMYK, a five-colour set up using CMYK, plus a white ink and a six colour set up can be achieved with the inclusion of a varnish. As you would expect, the XpertJet 1682UR comes with easy to change ink cartridges, each filled with US61 ink which can reach the most stringent of EU controls for environmental concerns. The inks are developed to give up to 200% elongation with reduced stickiness post curing as well Colour, Layer on Layer Following a complete design review, Mutoh have come back to market with a thoroughly updated version of the ValueJet 1638UR with the XpertJet 1682UR The machine is a reel fed digital printer reaching up to 1625mm in width, with a maximum printable width of 1615mm
