Double Sided Proofing System
The Double Sided Proofing System developed by Preproofer produces double-sided proofs in 16-Up, 8-Up and 4-Up formats fully automatically. The system is based on the Epson Stylus Pro series, enabling print paper widths of 61 cm (24’’) to be printed with the 7450/7880, 111 cm (44’’) with the 9450/9880 and XXX cm (60") with the 11880. Data management and control is handled by the DI Plot software solution.
Imposition Production
Nowadays, the production of formproofs is mostly carried out with manual adjustment and glueing of front/back printwork. Apart from the considerable time involved, when printing on one side only, one side of the sheet will always go unused. The quality of these manually produced proofs is unconvincing. And the double thickness of the paper also makes for difficult handling.
High quality with less time and lower costs
The Preproofers for Epson do away with these drawbacks: leading inkjet technology and a simple design concept ensure that the production of double-sided proofs is quick and efficient, and that output quality is high. Two Epson printers are arranged one above the other on a stable platform, linked by a paper guide unit running from top to bottom.
Printing of the front takes place off rolls with a sixty-metre capacity. The paper is automatically cut and, falling under its own weight, reaches the lower printer via the guide unit. The sheet is automatically fed to the second printer for printing the back in register.
The 15 cm (6’’) diameter roll cores stop the paper curling at the end of the roll. The paper used is «mediaware DIL Preproofer DUO», and is specially produced for this core.
Faster printing, minimum ink consumption
The Preproofers for Epson harness the unique strengths of MicroPiezo printing heads. The technology is based on the drop-on-demand concept and enables precision control of the size, shape and positioning of the ink droplets on the substrate. This leads on the one hand to brilliant printing results, and on the other hand, thanks to the option to vary droplet size according to the subject, to a much faster printing process plus significant savings in ink. The Epson Stylus Pro printers have a four, seven or eight-colour printing engine with separate ink cartridges. A resolution range between 360 and 1440 dpi can be selected for the output.
