In today’s trend of high quality colour output, mono printing is often seen as the poor relative to its colourful cousin, so when Océ South Africa, a leader in digital document management and delivery, said that it had an exciting new black-and-white print technology to unveil, the print industry’s interest was piqued. Océ South Africa is marketing the Océ VarioPrint DP line of light to mid production machines (110, 120 and 135 pages per minute), as high quality replacements for existing mono machines and productive upgrades for the modern print room, or central reprographics department (CRD), wanting to make the transition from offset to digital black-and-white printing. Hennie Kruger, DDS product and marketing manager at Océ South Africa, said, ‘Many believe that the mono printing market has peaked, but 75 percent of all production pages are still black-and-white including legal documents, instruction manuals and direct mail all need to be printed cost effectively and users of mono will still need to upgrade their machines and be more efficient.’ He added that it was important for Océ to develop a machine that offered better print quality, performance and usability than existing devices. ‘In a market that already has good, compact, clean, efficient systems, Océ was determined to push the boundaries. Our research team developed fundamentally new printing technology that will exceed our customer expectations,’ he explained. Established technologies In fact, the Océ VarioPrint DP line uses two core technologies that Océ has had in its armoury for a number of years, which it has now adapted and combined to create a 100 percent digital, single-step process for converting digital data to the toner image. A variation on Océ Direct Imaging technology, Océ Direct Press rewrites the rules for image consistency, intuitive operation, system configurability and performance uptime. It replaces multiple process steps involving many variables with a single, stable digital process. It isn’t affected by light, static charge, temperature, humidity, developer or toner mixtures. It delivers highly stable and consistent quality output without streaks, striping or banding. In fact, the Océ VarioPrint DP line has already become the first production device to receive a BLI 5 Star rating for print quality. ‘By charging the surface of the drum from the inside, and using mono-component toner with a magnetic iron core, it removes the need for an external laser or LED light source and the related problems of static and toner jumping, resulting in the cleanest possible prints, no toner waste, a more compact engine design and no ozone emissions for a better working environment,’ added Kruger. Another long established technology, Océ Copy Press, addresses the next stage of the process, as the toner image is transferred to a transfer belt and then pressed into a pre-heated page at a low fusing temperature, without the need for developer. ‘Due to the fact that the image is pressed directly onto the paper, there is no residual toner on documents. The print quality is better and more consistent with an offset-look and feel. And the toner doesn’t crack or flake when creased or applied to structured or textured paper,’ explained Kruger. Low TEC (Typical Energy Consumption) rating Additional improvements come from enhancements that Océ has made to improve the devices’ productivity and energy-efficiency. Océ HeatXchange transfers the fusing heat from printed sheets to new sheets entering the print path. Printed sheets are cooled and to-be-printed sheets are pre-heated in a single process. The technology reduces energy consumption by up to 30 percent, and minimises heat emissions for a more comfortable working environment. This contributes to a TEC value 10 to 80 percent lower than other mid-production systems. The ready-cooled printed sheets also results in no curling or sticking, and more reliable finishing. Océ EnergyLogic technology improves productivity in two main ways. Firstly it enables uninterrupted production for jobs with mixed light and heavy media. For heavy media, the system gradually reduces speed to keep performance at a maximum without compromising print quality. It then resumes full speed for lighter media without ‘hiccups’, intelligently gearing up and down for media changes. Secondly, it enables the device to start printing, albeit at a lower speed, as soon as sufficient power is available. Kruger expanded, ‘Instead of waiting until the engine has reached its rated speed, the device will start printing at 60ppm, which means that you could have 200 sheets in the output tray in the time it takes other machines to warm up.’ Taken together, the Océ VarioPrint DP line’s image quality, consistency, energy efficiency and productivity make it a compelling addition to the monochrome light production market. ‘The system cost and running costs will be comparable in pricing to other systems because we can’t afford to have a more expensive system. But for the same level of investment you receive high quality, reliability and a better environmental solution and lower energy costs, so the total cost of ownership will be lower,’ concluded Kruger. The article in the printed magazine featured the wrong device.
