Control a charter

In this tutorial, we will learn how to control an IT8 type chart by measuring the lines in one or more times.

The control of a large chart can be useful in the following cases:
- More in-depth quality control of your prints
- Verification of charts intended for the creation of a profile to characterize an offset machine.

Importing the Print Control file

To control a large chart, it is first necessary to import the Print Control file created previously in the " Creating a reference from ... " chapters:

Then select the Print Control file and right click to select the " Start Control " option.

It is possible, at this stage, to modify the format of the test chart in order to print it.

Multiple measurements

At this step, it is possible to define the number of measurements carried out per line by clicking on the " + reading "
button. This is in order to detect reading errors or to average the measurements for greater precision.
