four-zone vacuum system which can be switched on or off where required on the side of the machine. This has a number of advantages; the issues with vacuum supply are well known and there is a dramatic drop off of pressure should air inlets be open to the atmosphere. By being able to reduce how many are doing this, will greatly increase the vacuum pressure where it is needed, in turn giving greater draw down to the substrate. Holding it is not the only aspect to consider – where it is held is equally important. To ensure the substrate, specifically for multiple prints, is consistently reproduced the vacuum table has a series of holes and stops. This means the pins can be located on the plate for the substrate to be located against, firmly securing it where it is required. Static can be a major issue on materials which tend to retain it or with the passing of the print head, stimulate the production of it too. To counteract this, as it can greatly affect the deployment of the inkjet process, ColorJet has as an optional static suppression system which will greatly reduce the charge. Moving Swiftly On The head itself is held above the table on a large and well-designed overarch which ensures no matter how far across the print head travels, there is no change in height, which can change the printed outcome. Driving the heads are two servo motors which seamlessly sweep the head across the table. There are always going to be instances where the head could come into contact with the substrate. To avoid this damaging the head itself, there is an anti-crash sensor system which will stop the head on a sixpence and stop likely damage. If the printhead moves too far to the left or right of the printer itself, there are hydraulic stoppers to protect it. As we outlined in the introduction, India may not be the first place you would consider exporting graphic equipment from, but thankfully there are sellers more close to home like Quality Print Services (QPS) to help you out. need to constantly monitor the volumes of ink in the printer. ColourJet has designed a low ink volume alarm to alert staff there is a need to replenish the printer with new ink; this is particularly helpful when running with reduced manpower. Holding on Tight The colour and print heads are just one aspect of the package, without equal control of the substrate all the investment in time and energy is for nothing. So, what do ColorJet do to ensure the substrate stays exactly where it is needed? The printer has a large plate for substrates up to 2.56 x 1.68m in area and 100mm thickness. This means the nature of what is to be printed can be almost endless. Regardless of the thickness, the material is held flat and secure by a Brian Sims Principal Consultant, Metis Print Consultancy, www.metis-uk.eu K2513R5 K2513R6 Print heads 3 to 9 (7pl) 3 to 9 (5pl) Media size 2.56 x 1.68m Media thickness 100mm max Printable area 2.5 x 1.22m Colours CMYK, W, & Varnish Resolution 1,200 dpi Statistics ▲ There is a number of combinations of heads and modes to ensure a balance of volume and quality can be attained 25 Issue 256 - December 2024 / January 2025 email: editor@signlink.co.uk UNDER THE HOOD / VERVE LED 2513
