The Lab values your scanner sees, are defined by the scanner profile! Most scanners can just see red, green and blue. The question is which red, which green and which blue. RGB is a color system that cannot define colors unambiguously. Not until we interpret the RGB values, will we know which colors are actually behind them. basICColor scan+ delivers you this interpretation in the form of a perfect ICC scanner profile. basICColor scan+ does not only work with the usual IT8 targets but also with basICColor scan targets and the new highly precise HutchColor targets. The HCTs have an unmatched density and color range. basICColor scan+ is as easy to handle as any other Photoshop filter. You scan a target, open it in Photoshop and start the filter basICColor scan+. Then you assign the reference file supplied with the software, name the profile and push the "Profiling" button; - done! Because scanners see each material differently, you need to make extra ICC profiles for scanning printed matter. basICColor scan+ allows to do so with the help of a basICColor rescan target. After calculating the profile, it will be applied to the image of the target. Small squares in the center of each color patch show the correct colors based on the values in the reference file. If these squares are not different from the surrounding color patches, your profile is perfect.
