A double-sided Epson proofer
The Preproofer for Epson uses leading Epson Stylus Pro inkjet technology and is controlled by the DI-Plot bitmap software.
The Preproofer for Epson produces double-sided proofs in 8-Up and 4-Up format 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, and 111 cm (44'') with the 9450/9880. Data management and control is handled by the DI-Plot software package.
Is your formproof production efficient?
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 Preproofer for Epson produces up to 16 double-sided printed proofs per hour in 4up or 8up format.
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.
Simple data handling with DI-Plot
The Preproofer for Epson is controlled by the DI-Plot proof software, which is already operating in more than two thousand installations.

DI-Plot accepts ROOM data («rip once, output many») from almost any workflow. Not only 1-Bit-Tiffs, Delta lists, CT/LW and files in Epson ESC/P plotter format, but also Apogee, Prinergy, Prinect, Harlequin Rips, etc. are all part of this high-performance software's repertoire. DI-Plot runs on the Windows platform. Connection to the printers is via ethrnet ports for data transfer and printer control. Synchronisation of the two printers is secured by special electronic circuitry integrated into the system.

Individual profiles can be produced for the Preproofer in addition to the ICC profiles already included in the delivery. The processing of complete printer data in the Epson language allows connection to any workflow or any proof-rip as long as it supports the Stylus Pro 7400/7600/7800 or 9400/9600/9800. DI-Plot offers options for controlling further output systems and calculating InkZone and CIP3 data for presetting ink zones on offset printing machines.
Added value with high potential savings
The Preproofers simplify and accelerate proof production under economical conditions. The comparatively low investment and high potential savings mostly mean that they pay for themselves in less than one year. At present many printing houses are today already employ an Epson Stylus Pro printer. By upgrading to the Preproofer, substantial value can be added to these existing printers. So their productivity will be far greater.
