Inkcheck (Colorguide) - Techkon SpectroDens Manual

InkCheck (ColorGuide)

The measurement function InkCheck (ColorGuide) combines in a very easy way
the advantages of colorimetry with the familiar densitometry. Thanks to this helpful
function, working with the process standard ISO 12647 is simply achieved. The colori-
metric deviations are reported and additionally recommendations for amounts of ink
supplied in terms of density values are given.
In contrast to the measurement function ISO-Check the measurement function
InkCheck (ColorGuide) is not only able to check the CMYK print ink, but also spot
colors, provided that the appropriate spot colors were chosen as references in ad-
vance. In addition to the color books which are included in the contents of delivery,
for example the HKS-color books, you can create your own color books for spot
colors and use them as a reference.
The recommendations for amounts of ink supplied in terms of density values for spot
colors are based on CIE L*a*b* measurements.

First, a color book which holds the reference
color data has to be selected.
The reference values for the 5 paper classes
defined in the ISO standard are pre-set in the
device memory.
The data set "Proof" is for measurements
on white backing and the data set "Print" for
measurements on black backing.
If they can not be found in the device mem-
ory, they can be uploaded with the Windows
software SpectroDens Connect.
After selecting the right color book, load it in
the reference memory.
