The Techkon SpectroDrive scanning and measurement device, paired with the Windows-based TECHKON ExPresso 4 software, forms a complete quality-control system for increasing the productivity and quality of a printing press. It measures density and color across the press sheet and feeds the data straight into ExPresso for analysis and ink-key control.
Highlights:
- M0/M1/M2/M3 measurement modes — for compliance with G7 and the latest ISO standards
- Screen on scanner — displays color values, density, battery/wireless status, and current measurement conditions
- Laser guide — verify color bar alignment easily before scanning
- Rugged build — solid aluminum casing, wireless charger, and an improved wheel design
- G7 functionality — recommended ink-key-specific C, M, Y density adjustments for neutral G7 values
- Flexible ink zone control strip — can be printed and measured anywhere on the press sheet
- InkCheck — measures density and color and suggests ink-key-specific density changes for more accurate color
Versions & functions. Two packages are available — ExPresso Basic and ExPresso Pro — and a software upgrade from Basic to Pro is available.
