machines, so they are easier to mount onto a thermoformer and occupy less line space than a TT printer. Then there is the issue of upkeep; TT printers have a lot of moving parts such as springs and pulleys that require maintenance. By contrast, TIJ printers have no replacement parts other than the inkjet cartridge. All of these benefits combined result in a much lower cost of ownership for TIJ versus TT. With the thermoformer producing 10 packs per cycle (two packs long, five across), Rotech’s solution was to fit five X1 Jet TIJ printheads in a fixed position across the web to print the film as it passes through the machine, eliminating the need for an expensive indexing system. “Set-up time is far less than with Indexing systems are an expensive independently controlled coders,” explains modification to be avoided if possible. Steve Ryan, sales manager at Rotech. “The X1 is ideal for centrally controlled applications. It is an entry level printer and doesn’t have a built-in interface unless a Because of space limitations, the customer specifically requests one.” coders were installed in a staggered The printers use iDesign format creation configuration on two frame assemblies, one below the other, with three on one row and two on the other. The film web is coded in a vertical position before being applied to the pack. software, which not only enables the user to create and edit the print image from the central PC, but also provides useful updates, print quality checks and ink consumption levels. rather than having individual control “This project is a great illustration of how TIJ networked to a central PC. be indexed or the printer to be moved back across the web, so there is no need for an indexing unit and there is no ribbon wastage. Added to this, it’s a simple, easy to use installation that requires no maintenance or servicing - just the occasional replacement of a click-in, click-out cartridge,” says Steve. information such as ‘job completed’ A further benefit of this set-up is that panels on each unit, the coders are all This configuration doesn’t require the film to can offer a simple and lower cost alternative to other more complicated and costly coding Rotech Machines www.rotechmachines.com Tel: +44 01707 393 700 systems.
