Colour System Evaluates Mini Spots In
Production
The Prinect Image Control spectrophotometric colour measuring system from Heidelberg is now available in the new version 4.0 to automatically evaluate Mini Spots during production.
The Prinect Image Control spectrophotometric colour measuring system from Heidelberg is now available in the new version 4.0 to automatically evaluate Mini Spots during production Mini Spots, for which Heidelberg has just received the German printing industry award for innovation, are small control elements that can be printed on free areas on the print sheet and are used for process control

They provide information on the colour space and dot gain on the print sheet.
Prinect Image Control 4.0 measures the entire print sheet, complete with Mini Spots, using spectrophotometric technology.
The tonal and colour values obtained are sent to the Quality Monitor analysis software for evaluation.

Heidelberg's New Workflows and RIP
Heidelberg will be supplying customers with the latest release of its automated prepress workflow, Prinect Printready System 1.2, with immediate effect.
The software enables instant statistical analyses for all imaginable measurements.
Any discrepancy is corrected immediately in the pre-press stage, which enables the printing process to be monitored rapidly and reliably on the fly and ensures consistently high production quality, said Heildelberg.
"The launch of Mini Spots means Prinect Image Control users can enjoy greater reliability and efficiency in their colour workflows.
Mini Spots provide far more quality information on the printed sheet than conventional colour bars and do so in real time.
For the printshop, this increases productivity and strengthens customer loyalty, as quality can be reproduced with complete reliability," says Jorg Bauer, vice president of Prinect product management at Heidelberg.
The company added that Mini Spots are claimed to allow printshops to respond faster to changes in the colour workflow.
They can be used for printing and proofing and it is here that the strengths of Mini Spots really come to the fore, added Heildelberg.
Whilst it was previously always necessary to print complete test forms - a costly and time-consuming process - now it is often sufficient to simply print Mini Spots in process.
The values obtained from the Mini Spots are used to adapt existing printing characteristics and ICC profiles to changes in print conditions.
For optimal results, Mini Spots should be combined with Prinect Profile Toolbox profiling software and Prinect Calibration Toolbox calibration software, said the company.
The Quality Monitor analysis software in the toolboxes evaluates the data and shows whether the process is correct, or whether corrections are necessary.
If corrections are needed, they can be applied immediately to the printing characteristic during plate manufacture (Prinect Calibration Toolbox) or to the ICC profile (Prinect Profile Toolbox).
After the correction, the next proof and plate set are matched to the new printing conditions and the process control feature is claimed to produces far more uniformity in the quality of print products in a shorter time.
Mini Spots can be positioned on the print sheet independently of the colour bar, whenever the printing process needs to be controlled, with precision - such as when printing multiple-ups for labels and packaging, for instance, said Heidelberg.
