| The first step to calibration is getting a scan of your IT8 card. If you have gone through the software part of the guide, you should be able to use Canon, Epson, or Vuescan scanning software to get a "flat" RAW scan of your card. 400-600DPI is recommended as the calibration software sometimes has issues with high resolution scans at 800DPI or higher. Crop around the card so there’s no white space. If you crop into the card a bit it’s okay as long as it’s within the initial grey border. Also make sure when you're scanning the card that you remove it from the protective sleeve, as some people have scanned it while it was still in the sleeve which you don't want to do. | The first step to calibration is getting a scan of your IT8 card.

Make sure you don't use any kind of TIFF compression (This is default behavior) when saving your scan as that will cause it not to be able to open in the calibration software.

| The biggest key to calibration is to scan your IT8 target in exactly the same way you plan to scan your boxes/manuals etc. So if you’re planning on using Epson Scan and scanning in 24-bit, you’ll need to scan your IT8 target with the exact same settings. If you’re planning on doing 48-bit as well, then you’ll need to scan and calibrate separately for that. It’s really up to how you want to do it. For most users having a single calibration file will be all that’s needed because you’ll likely always use the same settings and software when scanning. | The biggest key to calibration is to scan your IT8 target in exactly the same way you plan to scan your boxes/manuals etc. So if you’re planning on using Epson Scan and scanning in 24-bit, you’ll need to scan your IT8 target with the exact same settings.

| Our recommended GUI Windows solution is a software called [[http://www.dohm.com.au/coca/|CoCa]]. 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 [[http://www.targets.coloraid.de/|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 go ahead and start the CoCa software and it will look similar to this. | Our recommended GUI Windows solution is a software called **CoCa** ([[coca|download]] [[http://web.archive.org/web/20210922085013/http://www.dohm.com.au/coca/|archived website]].
