Roland DG launched the SolJet EJ-640 wide-format inkjet printer, which is targeted at the sign market, at the end of October. The premium high volume printer has dual staggered print heads, an integrated tri-heater system, strong industrial design and high-capacity 1-litre ink cartridges available in four- or seven-colour configurations. In a mirrored CMYK ink configuration, the EJ-640 can achieve speeds of up to 102m2/h. The EJ- 640 utilises specifically designed EJ Ink, developed alongside the machine to offer end users lower operating costs for high-volume and long-run print jobs. The EJ-640 is accompanied by Roland VersaWorks Dual RIP software, which offers customers the ability to process both PDF and PostScript files natively, including files with transparencies.
