In this movie, I'd like to show you how to calibrate, or create a custom color management profile for your scanner. The reason for this is, when we create a custom profile, it improves the accuracy and consistency of your scanning. I mentioned in the previous video, the one on setting up preferences, that setting up preferences, and doing calibration are kind of related to each other, and that's because we're going to be creating a custom profile using this target, and then our goal is we're going to be moving into the Color Management section of the Preferences. In the last movie, we chose the generic profile for the Epson; this reflective profile.
What we're going to do is replace that with a custom profile, again, to improve our consistency, and color accuracy. You'll notice that there is a bunch of profiles that have already have been placed in here during the installation, and if you have problems locating the profile folder, you can search for the word profile, or you can search for one of these profiles, and when you find the folder where the profiles go, you'll see these different names from the SilverFast profiles, and then you'll know that you're in the right place. So that's where we're headed, and that's why we're doing it. First step is to do a prescan. You can just click on Prescan after you put your target down, and remember to clean your scanner; clean your target. The prescan is done, and then the next step is to generally place the frame inside of the target here Get it kind of close, and then we're going to move down here, and click on the IT8 calibration icon.
And then, remember, we talked about the Auto IT8. We had it turned off. Even if you have it turned off, you can turn it on here if you wanted to, and typically I don't like to do that; I like to do it manual. If you think you can place these small squares inside all the colors, and inside all the grayscale areas, you can get close there. Or if you can't really quite see it, you can click here, and then when it starts to run, you can just click this button here to stop the process, because you'll get an enlarged view. Although we did a pretty good job, by golly, of putting it up there, even with a pretty small view.
So you just want to make sure that all these squares are inside of the color swatches, and all these rectangles are inside of the grayscale, and then you can start the process. And then, what the software is doing is it's measuring the color values, and creating a custom profile. If it's successful, it'll give you this dialog box here. It says it succeeded in the DeltaE equal to 1.0, which means everything is cool. And then it's going to ask you to name and save the calibration profile. My recommendation is to put your EPSON Perfection, and you can shorten it up, so it's easier to see; call it the 750, and then you might want to put a date.
If you're going to do this, like, say, once a month, then you can go 02.12. If you do this once a week, then you can put in the week that you did it as well. And notice that we're putting it in, in this case, it's in the Macintosh; it's in Library > ColorSync, which is the color management software that's being used, and Profiles. And SilverFast should find this folder automatically, whether you're working on a Mac or Windows machine. If it doesn't, you may have to look for this folder, and you may have to do the search outside of the software; you may have to do through your OS to find it, and then navigate to here, and click Save. There we go.
So we've created our profile, and the last step is to go back to our Preferences, and go to the Color Management, and then find our EPSON Perfection profile. Notice that it's been automatically placed there for us, which it should do, but I recommend that you just check to make sure that the profile has been automatically selected, and if it hasn't, you can just click here, and then you can go find it. And there's the date. By putting the date, it's easier to distinguish it from all these, plus, it's a good idea to do this at least once a month. So there's setting preferences in the previous movie, and that kind of works hand in hand with setting up your color management system to give you more color accuracy, and color consistency.
