Colour measuring instrument specialist Techkon has upgraded its SpectroDens handheld spectro densitometer.
A new scan-function for individual control elements means the instrument can measure density and spectral values of up to 54 patches in one scan. Advanced pattern recognition algorithms secure correct readings. For the scan, no guide bar is required - four wheels keep straight alignment while scanning.
There is now support of the common ECI/bvdm Gray Control Strips tvi10 and M i1 with ISO-Check function that allows users a performance check in accordance to ISO/PSO within three seconds.
New paper indices to check quality of printing substrates are now available too. Functions like Whiteness Berger and Stensby, Brightness TAPPI 452, Yellowness CIE and Opacity help to analyse the quality of paper.
A new SCCA reference value correction allows printers to achieve an acceptable colour match regardless of the presence of optical brightening agents in substrates.
