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
