The new auto-scanning spectrophotometre scans press sheet colour bars in seconds while simultaneously sending spectral and density measurement data to a PC running Techkon Expresso software. Users can scan a 40” press sheet in less than 8 seconds. The measured density and colour information is displayed with suggested density changes for more accurate colour. Specifically, colour values, density, battery/wireless status, and current measurement conditions are displayed. Its Laser Guide can verify alignment of colour bars more easily before scanning. The SpectroDrive uses G7 functionality with recommended ink-key-specific adjustments of C,M,Y densities to obtain neutral values according to the G7 specification. Also, an Ink Zone Control Strip can be printed and measured anywhere on the press sheet.
