 ===== Windows Solutions =====
-Our recommended GUI Windows solution is a software called CoCa which you can download [[http://www.dohm.com.au/coca/|here]]. It's fairly easy to use and produces great profiles! So go ahead and download and install that. You'll also need to download and unzip the ZIP file tied to the Charge Number in the lower right corner of your IT8 card if you ordered it from our recommended vendor [[https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwjvwZztk_HrAhVFVK0KHfyeDUQQFjAEegQIBRAB&url=http%3A%2F%2Fwww.targets.coloraid.de%2F&usg=AOvVaw08-cLCjvuFzVvGdUPKv6zj|here]]. Scroll to the bottom of that page and look for your charge number and download and extract the ZIP file. You'll need the .txt file with the same Charge Number from this for calibration. Now go ahead and open the CoCa software up and it will look similar to this.

 **Options** - Select Display XYZ cLUT + matrix as your algorithm, Default Intent I pick Absolute Colorimetric here as I commonly use that when I convert my images to SRGB but Relative is fine here too. Quality I would set it to High.
-After you've set your options like that click the Create Profile button. You'll see a black box pop up and it will process a bunch of stuff. Once it's finished if everything went okay you should get a Save dialog box. Make sure you save your profile to C:\Windows\System32\spool\drivers\color as that's where Windows looks for IT8 profile. Once that is finished you're done and you now have an IT8 profile you can attach to your scans in your image editing program of choice. Congrats!
-===== Mac & Linux =====
-Our recommended Mac & Linux solution is a software called ArgyII which you can download [[https://www.argyllcms.com/downloadmac.html|here]] for Mac and [[https://www.argyllcms.com/downloadlinux.html|here]] for Linux. You'll also need to download and unzip the ZIP file tied to the Charge Number in the lower right corner of your IT8 card if you ordered it from our recommended vendor . Scroll to the bottom of that page and look for your charge number and download and extract the ZIP file. You'll need the .txt file with the same Charge Number from this for calibration. Now open up a command prompt and browse to your ArgyII directory.
-Run the following commands -
-scanin (your-it8-scan).tif it8.cht (charge-file-number).txt
-That should output a .ti3 file that you'll need to use in the next step that should be named the same as your TIF file. Run the following command now -
-colprof -D"Type in a description for your profile here such as the Bit-depth and Scanning software" -qh -aX -Z a (it8profilefilename)
-If all goes well that should output an ICM file in your Argy folder and you now have your IT8 profile!
-If you have a Mac you probably need to place it in /Library/ColorSync/Profiles/ for it to show up in your image editor of choice.
-For Linux it's usually placed in one of these places -
-/usr/share/color/icc
-/usr/local/share/color/icc
-/home/USER_NAME/.color/icc
-===== Attaching the IT8 Profile to your Scans =====
-If you placed you IT8 profile in the correct folder it should now show up in image editing programs and you can attach it your scans. Below are directions for GIMP and Adobe Photoshop.
-==== Adobe Photoshop ====
-Open your image and then go up to Edit on your toolbar then Assign Profile.
-{{:calibration:capture5.png}}
-Check the dot next to Profile: and then find your IT8 profile here and click OK.
-{{:calibration:capture2.png}}
-That is it! You should now see your scan color corrected. Save it as either a TIFF (If 48-Bit) or PNG (If 24-Bit) and you are done. Remember that a lot of programs (Including Web Browsers) won't display IT8 profiles but if you see it in your image editor it is there and correct. So don't freak out if you don't see it when you view it on the web.
-==== Gimp ====
-Open your image file in Gimp and navigate to Image - Color Management - Assign Color Profile
-{{:calibration:capture3.png}}
-After clicking that a dialog box will appear. Click Assign and the browse for the ICM file to assign to your scan. After that is selected select Assign.
