# Create an icc profile from an average of measured charts

Creating a characterization profile from measurements taken on a sample of several test charts is necessary to characterize an unstable printer or press.

In this tutorial, we will create a characterization profile from a sample of 3 CMYK test charts of the ECI2002R type.

This profile will be produced in 4 steps:

* Printing of test charts
* Take and measure the 3 staffs
* Compare the measurements of the 3 test charts in order to check the quality of these and check for any measurement errors.
* Take the average of the 3 measurements then start the profile calculation.

### Printing of charts

In the profile creation module, click on "**Create a characterization**" then on "CMYK"
