Create a media profile

This tutorial explain how to create your custom profile for your own use case without calibration step.

To print correctly the right colors, you need a paper profile that match your print configuration.

  • Either you use the settings and paper profile given by the paper manufacturer, but sometime it not enough.

  • Either you might need something that fit your need more precisely.

  • Either you don't have the paper profile because manufacturers doesn't provide every icc profile for every printers and resolutions.

    For alls these reason, let's see how to create our own profile together.

Create your custom profile

Before to start this procedure, you have to go on the paper manufacturer's web site to get information which help you to create your paper profile. E.g.: To get printings conditions for your target and yours printouts.

Let's start the profile creation module by clicking on the Printer's logo at the top left corner.

The Profiler's windows will appear. Now select the "Caracterization" icon, "New configuration" then "Validate" to go to the next step.

If you want to create a calibration before your Characterization, please follow the tutorial "How to create a profile from a calibration"

The path

Before to start, it's should be useful to have a look on the Path in the upper side to browse into the different steps during the icc profile factory.

  • Stop : click on "Stop" to exit the procedure

  • Characterization: Select RGB or CMYK mode

  • Mire Creation : Parameter to create the chart

  • Printing : Get target for printing

  • Read Target : Target Reading

  • Calculate Profile : Choose parameters to compute the ICC profile.

Characterization: Choose your color mode

Write the name of your Icc Profile, then select the color mode. You do have the choice between RGB mode and CMYK mode.

Generally, you will select the RGB mode to create profile if you need to print from a driver. (If you want to print from Photoshop or another application.e.g.) If you print from a professional RIP (like EFI, Caldera, Onyx, Ergosoft, Wasatch, neoStampa, Epson Edge Print, etc...) it may be possible that you need to create your icc profile into the CMYK mode.

We've chosen the CMYK monde for this tutorial. You might see different options in the RGB mode.

Mire Creation

1. Number of White Patch Test.

The white patches are usually very important in establishing white point that the ICC data is made relative to, so it improves robustness to use more than a single point.

2. Number of grey patches

This parameter sets the number of patches in a set of combined (nominally gray) wedges. These will typically be equal RGB or CMY values, and by default will be equally spaced steps in device space.

3. Number of patches

This parameter sets the number of full spread test patches. Full spread patches are distributed according to the default or chosen algorithm. The default algorithm will optimize the point locations to minimize the distance from any point in device space, to the nearest sample point. This is called Optimized Farthest Point Sampling (OFPS) . This can be overridden by specifying the kind of target.

4. Number of patches per CMYK primaries

This parameter sets the number of patches in a set of per colorant wedges. The steps are evenly spaced in device space by default, and the total number of test patches will be the number of colorants times the value specified.

5. Format of your target and the orientation

Select page format A4, A3, A2, Letter, Legal, 4x6, 11x17 or Custom

  • Orientation

  • Margins

  • Patches format

  • Resolution of the Target (Tiff files)

Once everything is setup, click "Next".

Printing: Export generated targets

Click on the "Save target" button to export Tiff files for printing.

Important: you have to print targets with no color management. To help you to print targets you can follow the procedure: Printing chart

Read Target

Be aware: You have to connect your spectrophotometer to start the process to create the icc profile.

Put you spectrophotometer on the calibration position, then click on "Start calibration" bar, then click on "Next" button to start the measure.

XRite I1 Pro 1 & 2
XRite Color Munki Photo & I1 Studio
XRite I1 Pro 1 & 2
XRite I1 Pro calibration position
XRite Color Munki Photo & I1 Studio
Color Munki Photo calibration position
Set your spectrophotometer in calibration position (on the white patch) then click "Start calibration"

If your spectrophotometer is not connected, you will get the following windows:

You need to connect a device - Here is the case without connected instrument

Now it's time to start the reading...

When the "Target reading" windows will appear, you have to click on "I'm ready" button and you can take your spectrophotometer to start the measurement.

When every thing is ready to start, click "I'm ready" button

The range is measured from the side of the letter to the opposite side.

It is necessary to leave a white space on each side of the measured line because the measurement starts with the white of the paper and ends on the white of the opposite paper.

The measurement starts with the line "A", then measure the line corresponding to the line highlighted in blue on your screen.

Read the row starting from the letter to the very last color

When the line is measured, a check mark appears on the right.

Before and after the line reading, you can hear a bip to indicate when you have to start the scanning and when the line scanning is done.

You can visually check if there were no errors during the line measurement, comparing the upper and lower color of the measured patches.

Actually reading the AT row. All previous rows are already checked.

If during the procedure you have a wrong reading, you can "Move Forward" or "Move Backward" with the up or down arrow on your keyboard.

When you have read a line, Coraye will make you read the next unread line.

Coraye detect automatically if you have commit a mistake during reading and display a warning message.

When the measurement is done, click on the "Next" button.

Calculate Profile

Before calculating the profile you can choose some options:

  • The profile quality (We suggest you working with medium one, since the high is very, very long to calculate)

  • The reference illuminant (D50, D65 ...)

If you had select CMYK color mode at the beginning, you will have more option to create your Icc Profile, you can play with the black GCR option into the graph and the inks limit.

Choose your reference illuminant

You can use a target profile to compute your output profile.

When settings are ok, click on "Calculate Profile" blue button.

Profile is calculating, just wait.

Check the profile

When Coraye is done calculating, the profile will appear on the left column.

To check the profile, you can visualize it into Gamut Viewer

Profile's Gamut

You can also check the curves with the Display Curves option by a right click on the profile name into the left column.

Don't forget to export your profile before to leave Coraye. If not, you will lost yours data


If you want to know more about the Gamut Viewer go to the tutorial Gamut Viewer

You can also print a test image to evaluate your print. You can download a test image here or here:

But be careful, you have to use a correct light to visualize your print.

If you want to check your light, you can use the Spectral Viewer module with your spectrophotometer I1 Pro or Colormunki Photo.
