Repeatability accuracy
Today the subject of colour is getting
more and more important. Quality criteria,
such as ensuring the colour consistency
throughout production, are important key
factors in the production process. The new
spectral inline colour measurement system
inco_check from eltromat was designed
exactly for this purpose.
inco_check is characterised by a simple
and intuitive operator workstation. Our goal
is to provide an easy and intuitive system
interface to make operator tasks simple and
quick.
The system is working during production
at printing speeds of up to 800 m/min
(2,625 feet/min) and delivering spectral
measuring results (L*a*b*C*H*) regularly
and accurately. This way you ensure colour
consistency in important areas at all times
during the production.
The integrated calibration against a white
standard saves space in the machine and
automatically ensures a continuous verification
of the calibration status during the process.
With inco_check it is very easy to do the
setting of up to 12 measuring points by a
finger tip anywhere in the printed image.
During the measurement exact colour values
(L*a*b*C*H*), colour deviations (as ∆Eab,
∆Ecmc or ∆E2000), the history and the trend
of the measurement results are displayed.
Your benefits:
_ Flexibility – because the system can be
used for all web printing processes.
_ Reduction of start-up times and waste in
new productions.
_ Reliable detection of colour deviations
allows very fast initiation of
countermeasures.
_ Comprehensive logging which can serve as
proof for customers.
With inco_check, you have the tool to
ensure a constant quality of your production
and also to reduce waste!

colour Functions
Functions
Absolute spectral measurement
With the aid of the specially developed spectral measuring
head, it is now possible to set and measure up to 12
measuring points successively throughout the entire
web width. The measured data is processed in real time;
therefore the measured values are immediately available.
Inline measurement of the spectral colour values
For defined measuring fields in the control strip or at any
desired point in the printed image, the detailed results are
displayed in a history.
_Colour values L*a*b*C*H*
_Colour deviations ∆Eab, ∆Ecmc, ∆E2000
Optimised printing process by spectral inline colour measurement
Detailed display of the current measurement data
Clear presentation of all measured data
Simple positioning of the measuring field by finger-tip
