Manroland Sheetfed has unveiled the Roland 700 Evolution press, incorporating many new technological developments and enhancements "to give printers unprecedented levels of efficiency, productivity, operation and quality".
A newly designed central console replaces buttons with state-of-the-art touchscreen panels. These give detailed graphical information in a user-friendly interface offering enhanced operation, flexibility and comfort, with options for left-handed and right-handed operation as well as customization for different operator body heights.
The new feeder pile transport brings appreciable productivity benefits with smooth upward motion of the pile-carrying plate and highly improved sheet travel from the feeder to delivery. This leads to fewer interruptions, less start-up waste and reduced walking distances to the feeder. Solid fixing of the suction head reduces vibration and wear while ensuring safer sheet separation and higher average printing speeds.
The new press also boasts completely redesigned cylinder roller bearings. Separate bearings for radial and axial rotation provide better absorption of vibrations with fewer doubling effects and ultimately, much longer bearing life and significant improvements in print quality. All-new dampening units in the new press bring greater solidity with fewer roller vibrations during passing of the plate cylinder channel and fewer stripes, says the manufacturer.
Sophisticated software for practice-oriented roller washing cycles further reduces downtime with much more precise dosage of the dampening solution over the entire width, reducing the possibility of skewing the dampening dosage roller.
Manroland Sheetfed's 'green print' innovations include a new three-phase AC motor said to combine the highest power output with lower energy consumption.
The new press also features a new chambered doctor blade system with additional profile to provide higher solidity over the entire width of the blade, and a more even varnish application. In addition to better absorption of vibrations of the Anilox roller and doctor blade caused by passing the coating form cylinder, it is also said to result in fewer stripes, especially in combination with pigmented varnish.
