UltraChrome DS inks can print on a wide range of substrates also demanded for point of sale (POS) products such as canvas and other similar POS substrates. Colour and the accurate deployment of dots is nothing without the substrate itself being controlled. Ease of Operation All printers in the range come with Epson Edge Print which is a software solution to make preparation and production as simple as possible. The main interface shows you a list of the current and past jobs for you to review and edit if needed. A set of tools sit in the toolbar at the top of the page and to the right of the split screen is a pane to allow the manipulation of the image needed for the job under preparation. Each Epson Edge Print can control up to four printers at a time, with tabs at the bottom of the screen detailing what each is doing. The Epson Edge Print Dashboard is an integrated product where you can download up to 250 different media profiles ensuring the printer is set at an optimum performance level so the most demanding client is satisfied. Wrapping up these two printers, they come packed with trusted and reliable Epson technology, it is a copper bottom purchase should you be looking for a dye-sublimation printer. The printers do not cost you vast sums to own and operate, Epson as always has the Total Cost of Ownership (TCO) in mind with easy maintenance and access meaning downtime is kept at a minimum. Brian Sims Principal Consultant, Metis Print Consultancy, www.metis-uk.eu tems (MEMS) which means elements of the head are placed 84.7 microns apart on silicon or glass. With ink channels and nozzles produced by the MEMS process, Epson claims the PrecisionCore Micro TFP printheads can produce almost perfectly round dots with great precision. With the PrecisionCore Micro TFP printheads having the print chip less than one hundredth the width of a human hair in thickness, by using materials this small you can have a relatively small print engine and large ink deployment. The PrecisionCore TFP printhead can place dots extremely accurately in both size and position in the colour gamut which is why Epson claimed the raw specification of DPI is now an “obsolete way to compare print systems” in its 2013 PrecisionCore White Paper. Epson also argues that resolution measured in dots per inch (DPI) is not necessarily the best way now to quantify print quality. The manufacturer does however agree that DPI is part of the methodology with greyscale and accurate dot placement also a key consideration. Wrapping up the printhead technology is Nozzle Verification Technology (NVT) which ensures the optimum condition of the printhead itself. NVT monitors the signals sent to each nozzle; it expects to see no resistance to the impulse squeezing the Piezo Electric film. Should it detect a rebound signal from the drive impulse, this is almost certainly due to the nozzle being blocked and the NVT technology adjusts the nozzle pattern to override the blocked nozzle, maintaining print quality. Supporting Ink Technologies The dot is laid onto the substrate with the help of patented technology called Look-up Table (LUT). LUT technology has been developed in collaboration with the Munsell Color Science Laboratory at the Rochester Institute of Technology in the US. The purpose is to increase the colour fidelity and gives a smoother graduation between colours. The Piezoelectric printhead uses the well-proven specially developed inks which are known as the UltraChrome DS range. This range of inks are developed to be Nickel-free and low odour meaning the SC range of printers can be installed in office environments which mostly now have air conditioning for airflow. The UltraChrome DS range of inks are also developed with the ability to print up to 98.2% of the PANTONE solid-coated colours which greatly enhance the printer’s ▲ The demand for printed and personalised textile prints has increased since Covid-19 The main interface shows you a list of the current and past jobs for users to review and edit if needed UNDER THE HOOD / EPSON SC-F6400/F6400H
