Sheetfed Presses--Getting Connected
Dr. Hans Grandin, vice president for sheetfed sales and marketing at MAN Roland, believes customers are looking for greater productivity through increased automation, faster production speeds and shorter makereadies. One example of a specific need being addressed by the company is printing on the backside—or inside—of packaging.
"Our backprinter unit allows single-color coupons to be printed quickly on the inside of a package, while up to eight colors are printed on the outside of the package to attract buyers," he says.
The backprinter unit, which is in its final stage of testing, is designed for the Roland 900 series of sheetfed presses, which can handle board and paper up to 56˝.
Remote Ink Control: Making Life Easier for Sheetfed Printers
By Peter Griffin, EPG president
What printer does not want to cut makeready time and increase productivity? The same holds true for reducing paper and ink waste and improving color control. Sheetfed printers can accomplish these goals without the huge capital investment of a new press by upgrading their press with a current remote ink control system.
Retrofitting a remote ink control system on an older press will provide many of the capabilities of a new one—at only a fraction of the cost. Moreover, a remote ink control system equipped with proper software enables a printer to take advantage of additional options like remote ink sweep, water and registration controls, as well as complete closed loop color control.
Advanced remote ink control systems also allow printers to link prepress systems to the press for automatic preset of ink fountain keys. By automating the setting of fountain ink keys, auto preset capabilities enable the printer to achieve additional reductions in both makeready time and associated waste.
Very simply, remote ink control systems work by automating the adjustment of fountain ink keys. The principle is the same as on conventional presses, but instead of adjusting the screws manually, the press operator remains at the remote computer console and adjusts the keys electronically. Once set, the settings can be saved on the computer and recalled for automatic ink key setting of repeat runs.
