The Proofer is the Press. . .

Digital Information continues to differentiate their proofing and digital printing solutions from the competition with the newest versions of their double-sided printers. The Preproofers 770/970, 789/989 and 790/990 are even faster and more automated than previous generations, and take full advantage of the latest, wide-gamut inkjet technology. The systems incorporate sophisticated registration technology to ensure that printing on the face and reverse of the web media is accurately aligned. The utilization of the new Epson Stylus Pro 7700, 7890, 7900, 9700, 9890 and 9900 printers brings new capabilities to the Preproofer: In addition to double-sided proof production, the system has migrated to a low-cost digital printing system for short runs or advance editions.

Incorporates Cutting-Edge Epson Technology

The 770/789/790 model is smaller for work up to 22''/56 cm print span and the 970/989/990 supports up to 42''/106 cm. All printer models use the same high- quality Ultra ChromeTM HDR pigmented ink to deliver brilliant quality on the distinctive, two-sided prints. And thanks to the new generation of TFP piezo print heads, these new Preproofers print significantly faster than their predecessors at the same resolution.

Extended Color Space and Stable Gray Balance

The Preproofer can crank out color-accurate contract proofs, or even faster content proofs – and both with one-sided or two-sided printing. Epson's unrivaled 11-color ink set (Stylus Pro 7900/9900) delivers the utmost in reproduction quality – cyan, light cyan, yellow, orange and green inks are used along with vivid magenta, vivid light magenta and four different shades of gray and black. As a result, Preproofer output extends into new areas of color space, especially in the hues of magenta, purple and blue. In addition, change- over from photo black to matte black is fully automatic, allowing for optimum adaptation to different media types. This allows contract proofs that are fully aligned with industry standards such as ISO and G7. While the large gamut makes easy work of otherwise challenging spot colors, the solution also offers stability in maintaining gray balance, and reduced metamerism.

Trouble-Free, Stable Production

With a minimum of mechanical parts, the Preproofer provides maximum productivity and operational simplicity. Each Preproofer incorporates two inkjet printers engineered in sequence to allow direct inkjet printing on both sides of the paper. The roll-fed system is natively efficient, and requires only a single pass through the system without the need for operator intervention to feed sheets or turn the media over.

New Brain Behind the System

The latest Preproofer 7700, 7890, 7900, 9700, 9890 and 9900 models take advantage of a new control system that assures accurate front-to-back registration via real-time video imagery. The control system continuously monitors and adjusts the print using a 128 bit code printed on the side of the media by the first printer. This innovative approach allows full assurance in the accuracy of print registration, and opens up attractive new digital-print application areas for the Preproofer, especially if equipped with the fast Epson Stylus Pro 7700 and 9700 five color printers.

Content Reliability

Since Preproofers are driven by data from the production workflow, operators can have full confidence that the resulting proofs are predictive of the on-press results. The Preproofer solution includes DI-Plot, Digital Information's bitmap proofing software which has been in stalled in thousands of shops worldwide. DI-Plot integrates seamlessly with almost any prepress RIP or workflow and converts the plate image bitmaps to the desired resolution for driving the Preproofer. And to make sure the Preproofer stays productive, the system uses SNMP steering to control the new systems. This system reports status messages such as printer readiness, fill level of the ink cartridges, production advance, paper end, etc. in real time. Commercial print, magazine and catalog signatures, packaging work and direct mail can all be printed accurately, productively and with perfect front-to-back registration.
