What is Expresso software?

ExPressoTM 4 by Techkon is the companion pressroom QC utility software that helps offset printers utilize the innovative features of our SpectroDrive automatic color scanner and SpectroJet handheld scanner in an open loop manner.  (For a complete closed loop solution for offset, see our PressLink fully integrated system.) It aids in scanning print control strips on printing sheets in seconds, making it an ideal and cost-efficient quality control solution for packaging printing in particular.

Results are displayed directly on your PC allowing you to make corrections immediately, even before color deviations can be seen with your eyes. Any print control strip with equal patch width can be used.

Process colors, special colors such as PANTONE®, substrate, dot gain, gray balance and density values are measured and immediately displayed clearly in ink zone specific diagrams. ExPresso 4 includes the display of up to 16 printing units, front-side and reverse printing, for evaluation according to color density, colorimetry, gray balance and calculation of the density adjustment for the lowest delta E.

The program supports key industry standards, including optical brightener M1, M3 for wet ink densities as well as ISO 12647, PSO, IDEAlliance G7, GRACoL and SWOP 2013.

The evaluation module can be used to create and print quality reports according to ISO 12647 or customer-specific standards. For a quick assessment of the entire order at a glance, a scoring with its own definition of priorities and weighting is available. Furthermore, ExPresso 4 now supports 16 languages for easy operation and offers touch-screen support.

All color references are managed in the color library of the software. Importing CxF3 color data is quick and easy. All job data including OK sheets are automatically stored in the integrated database, making setting up of repeat jobs a snap, and allowing set up of new jobs within seconds.

The measurement data can be exported to other programs via industry standards such as JDF, for example to realize direct online connections for automatic ink key control on printing presses.
