Thereby Reducing the Need for Cumbersome
This slows down the productivity of the machines, as the printer has to limit the amount of ink that falls on the material in each pass, and realistically limits productivity to just over 15 square meters per hour. Risky Investments In practice, many professionals maintain specific printers for specific print media, roll changes and ensuring that printer profiles are optimized for the media being used. But the more individual devices are added, the greater the maintenance needs. From a productivity standpoint alone, an alternative option is to invest in heavy duty 3.2m wide industrial grade printers. However, the cost of such an option often exceeds 120,000 euros, which requires a huge business risk for most entrepreneurs. The answer from Canon This is where Canon turns the tables, thanks to a fundamental evolution of the roll-to-roll printing process, the result of which is concentrated in Canon UVgel technology.A technology that redefines the relationship between ink, print head, material surface and curing system. In UVgel technology, the ink is in gel form and is liquefied image manipulation service with the help of heat to pass through the nozzles of the print heads. Once it exits the nozzles and rests on the printing material, it returns to its original gel form and then hardens with the help of UV LED lamps. The first product to use this new technology is the Océ Colorado 1640 64'' printer. UVgel technology allows the printer to deposit more ink in fewer passes, which translates into significantly faster production: the top speed of the Océ Colorado is 159m 2 per hour and 40m 2 in high quality mode. Once a strip is printed, it is cured using a curing system with UV LED lamps that move independently of the print carrier and print heads.

As a result, the speed of printed materials is no longer limited by the curing process, so productivity is substantially improved, compared to a conventional UV system. Also, the printed materials come out of the printer completely dry, and the operator can immediately move on to the next stages of cutting or laminating, without additional production delays. Another issue that creates production delays is the failure of nozzles in the print heads. With current technologies, a failed nozzle will fatally increase printer downtime while the nozzle is replaced. In the case of the Océ Colorado 1640, malfunctioning nozzles are detected before they spray ink - with the help of sound waves - recruiting "healthy" neighboring nozzles to fill the gap, without interrupting printing. The defective nozzle is therefore replaced during operation by a neighboring one, without any intervention by the operator, and the normal replacement can wait until the next scheduled maintenance of the printer, thus allowing its uninterrupted operation.
