Accurate Spectral Color Control
Clarios uses a true, in-line spectrophotometer to collect fully spectral color measurements on running webs, at virtually any web width, even at top production speeds. Its 31-channel spectral sensor accurately determines color values in conformance with ISO 13655 standard methods. So, Clarios’s ‘live’ color assessments correlate reliably with international standards for color management.
The printer sees immediate results on press-side displays. These can be easily configured to clearly present just the control values – from basic density to advanced colorimetry – that will most assist the working printer.
Efficient Color Management
As Clarios scans the running web, it collects detailed spectral information that is automatically processed to supply ISO-standard density, Tone Value (dot gain), Gray Balance, Colorimetry, and Color Difference (Delta E). Just the control points a printer needs for successful control are shown at press-side. But, all this detailed information is automatically saved to a Color Manager station.
At any time, any of this color data can be recalled for advanced color management – or to support thorough process engineering studies. No other color measurement system available offers a more complete picture of the actual, on-press printing conditions.
A Proven Solution
Clarios color control operates every day, on nearly every make and model of modern web offset press, around the world. Closed-loop interfaces to the leading press consoles enable stable production of superior images in all formats – publications, direct mail, high-quality books, and packaging for leading brands. For each challenging market, Clarios delivers a proven strategy for superb color control.
The Clarios on-web, spectral scanning solution supplies highly accurate, ISO-standard color measurement and control for modern web presses. Precise density, dot gain, and other print control metrics are gathered by scanning a mini-colorbar (as small as 2 mm in the circumferential direction) using a dual-beam, graphic arts spectrophotometer.
|True Spectrophotometry on the Web|
Spectral measuring probes, operating in programmable cycles, regularly measure control targets on the web. The Clarios measuring assembly includes a built-in calibration station where instrument response is checked automatically before each measuring cycle. Clarios accurately measures any color of ink, whether standard process color, extended gamut, or a special ink. Targets for solid ink, tints, and neutral or built-up overprints can all be scanned. The miniature targets fit into available space on most offset and rotary letterpress forms — No added white space is required. And the targets can even be ‘nested’ for use in complex packaging layouts
|Immediate Feedback for the Printer|
A working printer can monitor “live” print conditions from a variety of run control charts. The current condition of individual keys, of pages, or lanes, or alleys is clearly shown. As the Clarios probes scan, the latest results stream to the displays. Having full, up-to-date feedback in easy-to-understand reports means that printers can make the right decisions sooner, and with confidence.
Detailed Insight for Management
|Quickly Achieve Color Aims|
From the first scan, Clarios checks every key in every unit against your preferred color standards. Because each unit on each surface is adjusted concurrently, the press reaches targets quicker and stabilizes sooner.
Waste Reduction Throughout
Precise spectral color checks continue automatically as the press runs. This rigorous monitoring frees printers to focus on other press controls. Regardless of experience or skill level, the automated assist from Clarios provides a more stable print condition.
Demonstrate Color Compliance
Because Clarios is a true spectrophotomer with traceable instrument response, its reports speak directly to compliance with today’s advanced color standards. Color Manager’s built-in reports document press conditions with time-stamped results that demonstrate how closely the press conditions conformed to critical color quality parameters.
Enhance Customer Satisfaction
Today’s printer buyer expects that superior color is assured by pressroom automation. Subjective efforts and ‘close enough’ images are no longer acceptable. Clarios provides fully automated, standards-compliant, self-documenting control that is essential to success in the twenty-first century market.
Running Register Control
SnapReg –controls color-to-color (“running”) register on new or existing lithographic web presses. A robust, compact array camera monitors color registration. Able to register up to 8 colors per surface, using inconspicuous ‘micromarks,’ the SnapReg control can be added to any Clarios workstation.
Export & Analysis
Tone Value Analysis — gathers and reports detailed results about tone reproduction (Tone Value Increase) for a selection of tint values throughout the tonal range. After the print run, prepress experts, working at the Color Manager station, can select the most representative results to develop tone reproduction profiles (so-called “correction curves) based on “live” press performance on real jobs.
RunTime Data Export — an optional extension of the TVA module exports color results automatically, and in near-real time, for any target measured by Clarios. The exported spectral measurements are tagged in accordance with the methods of ISO 28178, so the results are available for import and analysis by leading third-party color management software. The operation is fully automated. Manual operator intervention is not needed.
CIP Interpreter – a digital analysis proposes recommended openings for the press’s ink keys by evaluating the PPF file, taken directly from the plate-setter’s RIP. This automated digital pre-setting tool has proven to be far more accurate than subjective estimates by the press operator – delivering measurable reduction in color make-ready. Further, when Clarios is connected to an AVT CIP3 Interpreter, the Clarios workstation can display images of the plates being pre-set, taken directly from the imagesetter’s data.
AVT’s closed-loop algorithms can drive ink key settings on AVT’s own Mercury automated ink key system. Or, Clarios can interface to ink keys controlled by almost all of today’s leading offset press manufacturers. The connection to Mercury means that digital closed-loop can be added to any older letterpress or offset web press. And the optional interface to OEM consoles assures that the newest presses on the market have ready access to advanced, fully spectral inking control from Clarios.
