# Create an icc profile from an average of measured charts

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"

![](/files/-MKQdXbVjDWxGPJvfxdK)

Select the "ECI2002R" charter by clicking on the button located under the charter.

When the chart is displayed, export the chart in Tiff or Pdf format in order to print it.

When the test charts have been printed, click on the "**Start reading**" button

![](/files/-MKQdjzWOh3r5Wk2mmeP)

Select the spectrophotometer options then click on the "**I'm ready**" button

![](/files/-MKQdpL5Hkx3Rs0rVecG)

Put the spectrophotometer in its calibration position

![](/files/-MBmacetMFAnXH6pkv2I)

Start the calibration by clicking on the "**Start calibration**" button

![](/files/-MKQdt212UeseuBmBKx3)

When the calibration is complete, perform the chart measurement.

### Measure charts

![](/files/-MIK6UK4iu0lcI2GHcBm)

When the chart is completely measured, click on the "**Export reading**" button located to the left of the "**Reading done**" button

{% hint style="warning" %}
Do not click on the "**Reading done**" button until you have read all the charts.
{% endhint %}

![](/files/-MKQdwOs9QhM0CnZNljN)

Name and save the chart measurement in .table format

![](/files/-MKVfKdMA8UIdqErtsub)

When the measurement is saved, click on the trash can icon to perform the measurement for the next chart.

### Compare measurements

{% hint style="danger" %}
When all the measurements have been saved, it is advisable to check their quality to detect any faults in the ranges (damaged ranges or measurement errors, e.g.).
{% endhint %}

{% endcontent-ref %}

### Average measurements

Import the measurements from the charts carried out previously.

![](/files/-MKQfZTq3NnYIU9yekbN)

The measurements are displayed as a color table in the left column

Click on the "**+ reading**" button as many times as there are measurement files. \
New "**Reading #**" buttons will appear as well as measurement lines.

![](/files/-MKQe9UxQXS7PZEyb8OC)

Drag & drop the color tables (corresponding to the measurements of the ranges) onto these buttons.

![](/files/-MKQeDA3ILzNTDikj8S9)

Then click on the "**Reading done**" button

![](/files/-MKQeGWnPCQH_qJIW2kJ)

Choose a name for your icc profile

![](/files/-MKVmI0B2c0etslNVpa3)

Once the profile parameters have been defined, click on the "**Calculate profile**" button

![](/files/-MKQeKNEAgj3rlEjKy5W)

### Profile calculation

![](/files/-MKVmSk4ceGGDSWYNsbU)

Once calculated, the profile will appear in the left column

![](/files/-MKQeP4ICOjvrjZVPyiX)

A Preview in the Gamut Viewer will allow you to visually control the quality of your profile
