ColorQuickRIP for High End Scanners and Recorders

Our ColorQuickRIP interface makes it possible to use the large record drum capability of your scanner or recorder to make PostScript images for a fraction of the cost of a conventional imagesetter. Our scanner RIP hardware interface is combined with a PowerPC Level 2 software RIP, freeing you from the constraints of a fixed expensive proprietary hardware RIP platform. Output size can be up to 44 by 50 inches on a Hell CP340 or CP345J. And not only can you drive a scanner record drum with the RIP, but it can also be used to drive an imagesetter.

Resolutions up to above 3600 DPI on Hell scanners or recorders or above 4400 DPI on Dainippon Screen scanners or recorders are available.

System Configuration

A Harlequin level II PostScript compatible RIP running on a PowerPC MacOS computer in conjunction with the ColorQuickRIP interface hardware is utilized to provide a high quality, low cost and fast PostScript output solution. The software RIP approach allows the flexibility of running the RIP on any compatible computer. This gives the added freedom to install the RIP software on newer, faster, lower-cost, non-proprietary hardware as technology advances. RIP processing and image marking can occur simultaneously and in the background, allowing use of the computer for other tasks.

The RIP can publish itself on the network as a PostScript compatible printing device, or PostScript files can be processed directly from any accessible storage volume. RIP processing can be done from a computer connected directly to the scanner or from an off-line station. The RIP output either drives the ColorQuickRIP hardware directly by linking to it using the ColorQuick software, or bitmap files can be created which are then marked on the scanner drum using the ColorQuick interface application software in conjunction with the ColorQuickRIP hardware interface. Quadro (1x4), duplo (1x2), double-duplo (2x2) and single image output modes allow maximum film utilization and productivity. On Hell scanners equipped with ColorQuick scan/record interfaces, automatic setup features are available.

All the screening is performed by the Harlequin RIP. The versatile configuration capabilities of the RIP allow the user to choose screen angles, screen frequencies and dot shapes. Harlequin Dispersed Screening (HDS) is optionally available and provides high quality stochastic screening, for truly superior print quality. Easy Trap built in trapping are also available as an option.

Interface Hardware

The ColorQuickRIP hardware interface drives all exposure beams/fibers simultaneously for maximum image marking speed (6 beams on Linotype-Hell Scanners, 10 beams on Dainippon Screen scanners). For input and output of high quality color directly to /from the scanner, the ColorQuickRIP interface may be combined with the appropriate optional ColorQuick CT (continuous tone) interface . When used with the ColorQuick CT interface on RS-232 data terminal-equipped or stand-alone Linotype-Hell scanners, automatic programming of the RIP record parameters into the scanner is provided.

The ColorQuickRIP interface hardware connects to the scanner after the digital dot generation (screening) circuitry. It directly controls the high resolution beams used to expose the film. Therefore the RIP interface can mark at the resolution of the individual fibers. This resolution is the crossfeed factor times the screen frequency times the number of laser fiber optic elements. For example on a Hell 341, at 60 screen dots/cm, a 2.0 crossfeed factor and six recording fibers, the scanner record drum marks at a basic resolution of 720 spots per cm (1828.8 spots per inch). When run at 120 dots/cm scanners a of 3658 DPI is supported.
