G R A N D F O R M A T • October 2017 • 29 try. This enables a uniform post-print UV curing that further contributes to print speed and print quality. Unattended printing, automated quality assurance, an unattended roll-change system, and reduced print waste all significantly con- tribute to overall productivity. Automation The printer sets a new standard in industrialization and automation, accord- ing to Canon. It features a heavy-duty drawer mechanism that holds up to two rolls of media at one time. The two rolls can be of the same media type and size or different media, and once initialized, the print engine can switch jobs between rolls without operator assistance. Reliability is key for a true produc- tion-oriented printer, and the machine must be able to print unattended. This is why Canon has developed several inno- vative technologies for on-the-fly quality assurance and control. The UVgel print- heads incorporate patented continuous nozzle monitoring to detect and correct any underperforming nozzles. During each and every printing pass, Canon's patented nozzle monitoring technology automatically checks all nozzles using acoustic sampling and even detects whether nozzles are going to misfire before they actually do. In the event of nozzle failure, corrective maintenance is automatically performed. SDG Canon enters the field with a new kind of inkjet printer that employs some intriguing technologies that can be applied to this market. At 64" the new Océ Colorado 1640 is not, strictly speaking, a grand-format printer, however with its unique new technolo- gies, the potential in that space remains wide open.
