How to calibrate your print with Coloris v2

To print correctly, it is necessary to use settings for each of your media on which you want to print.
Generally, if you use branded papers such as Canson, Hahnemuehle, Ilford, Rauch, Tecco  etc…  you will find on the web site of these paper manufacturer, informations on how to use them.

Other paper profiles can be downloader on software editor’s web site like , Dinax Mirage for example.
However, you will only find icc profiles for printers most used in the photo area.
Unfortunately, there are not all icc profiles for all printers and print resolutions.

In addition to obtaining more occurate colors, it is sometimes useful to make its own paper profiles…
… And it is there that Coloris will be able to be useful to you.

 

How to calibrate your prints with Coloris v2

  1. Click on the Profile’s logo at the top left corner, then select « Printer »

    Then the Profiler’s windows will appear.

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

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

  2. Create and Print Targets

    • Write the name of your Icc Profile.

    • Choose the RGB or CMYK mode.


      Generally, you will select the RGB mode to create profile to print through Photoshop or also application.
      Now, if you print though a professional RIP (like EFI, Caldera, Onyx, Ergosoft, WasatchneoStampa, etc…) it may be possible that you need to create your icc profile into the CMYK mode.
      NB: If you select the CMYK mode, you can limit the amount of ink during the printing with the « Ink limit » option.

    • Settings

      Settings Area

      1- Choose the 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- Choose the number of grey patches

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

      3- Choose the 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- Choose the 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- Sort patches

      Mix or don’t mix patches

    • Format

      Format area

      1- Select page format

      A4, A3, A2, Letter, Legal, 4×6, 11×17 or Custom

      2- Orientation
      3- Marging
      4- Patches format
      5- Resolution of the Target (Tiff files)
    • Export Target to Print

      Click on the floppy disk « Images Tiffs » button on the bottom right to export Tiff files for printing.

    • Print the target
      To Print target you have to follow the procedure « how-to-print-the-test-charts-to-create-your-profile« Warning: if you need to use a generic target as ECI2002 for example, follow the procedure: How to read a chart already printed…Warning: Use the Tiffs generated targets with the name of your profile.
