Colour Bar


pressSIGN's Colour Bar screen is designed for the press operator.

Here the operator can see each ink key/zone adjustment required in order to achieve closest match to the chosen colour standard.

CMYK & Spot colours in the colour bar will be displayed.

Colorimetric data from the spectrophotometer is automatically converted to density numbers, displayed to the left of each ink bar

pressSIGN displays information relating to the optimal density, L*a*b values and the ∆E distance from the target.


The large 90% score in green, denotes the calculated total score based upon a number of values including dot gain, and grey balance shown on the Summary screen.

Figures in red show measurements outside of the ∆E tolerance of the chosen standard.
