# Chart control

The control of a large charter can be useful in the following cases:

* More in-depth quality control of your prints
* Verification of charters intended for the creation of a profile to characterize an offset machine.

### Importing the Print Control file

To check a large chart, it is first necessary to import the Print Control file created previously in the chapter "Creating a reference from a printed chart":

{% content-ref url="quality-control/untitled-1" %}
[untitled-1](https://docs.coraye.com/quality-control/untitled-1)
{% endcontent-ref %}

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

The chart used when creating the Print Control file is displayed. It is possible, at this stage, to modify the pattern format in order to print it.

### Printing of the charter

If the chart is not already printed, export it in Tiff or Pdf format to print it.

### Charter measurement

Once the chart (s) has been printed, let them rest before starting to read. \
To start the measurements, click on the "**Start reading**" button

Then click on the "**Start calibration**" button

### 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 in order to detect reading errors or to average the measurements for greater precision.
