Scanner Profiling with i1Studio
Scanner Profiling with i1Studio
Open i1Studio and select the scanner profiling box in the workflow selector. Once this workflow is opened you will see the message indicating the correct scanner settings for the test chart scan. This message can be closed and will not open each time you enter the workflow by unchecking the option for "Show this Window on Startup". Once ready click the "X" on the top of the message window so the program can proceed. The message window will show the proper settings for the scanned chart.
Select the target type that you have scanned which include a number of popular reference charts such as X-Rite ColorChecker 24, Kodak, HutchColor, and Wolf Faust. Your scanned image must be an uncompressed TIFF file scanned at the following resolution:
• Reflective = 200 ppi.
• Transparency 4x5 = 300 ppi.
• Transparency 35mm = 800 ppi.
• ColorChecker 24 & SG can use any resolution but we recommend 150 ppi or higher.
Once the image is uploaded, you may rotate it to its correct position using the rotate tools underneath the image. The autocrop will detect the patches in most cases. If not you may need to use the autocrop option or the manual crop which allows the patches to be manually detected. Using the crop tools, align the crop marks with the image so each box of the color checker is perfectly centered. When finished, click next.
If the correct reference file has been loaded click next again. If not, users will need to click the load option and navigate to the proper reference file that matches their chart. In most cases, the X-Rite ColorChecker24/Passport and X-Rite ColorChecker SG reference files are selected automatically.
Create a meaningful name for your profile. It is a good idea to include the name of your scanner manufacturer, the model, the relevant scan driver settings, and the date. This is essential when locating different profile for different scanner and attributes.
After the profile is created you will receive a dialog box that will display the average delta E, the average delta E in gamut, the percentages in and out of gamut, and the average delta E of all CMC. After reviewing the information, click the home button to exit back to the main menu.
