I created an ISIS2 target image in sRGB with a set of 380 different LAB color patches. Each color was from the range of L* of 10 to 90 and a* and b* in increments of +/- 10. All possible 10 unit delta colors were initially created then all that were outside sRGB removed. The remaining were sifted through various profiles with and without OBAs using M1 and M2 profiles to find a set of colors that could all be printed witha Delta E < .5 when roundtripped through the profile set. Profiles for both the 9800 and 9500 were used.
The purpose was to create a set of colors in sRGB that were all printable on both printers with a variety of glossy paper.
Then the ISIS2 target image, in sRGB, was printed using various modes of Photoshop Managing and Printer Managing color. The prints were then scanned with the ISIS2 and the LAB results were used to create an exact image of the printed scans. However, some patches and printer modes did not keep the patch colors within sRGB (nor are they required to) and, in some cases many colors actually printed from the sRGB target exceeded even Adobe RGB. As a result, the attached image is in a ProPhoto, 16 bit tiff so all printed colors can be properly imaged. Each scanned image occupies a named layer in the tiff file which can be downloaded and viewed in Photoshop. Loading the tiff file in Photoshop allows one to select and alternate the printed images so it's easy to compare say, The Canon default driver with the Reference LAB image or a custom profile's Perceptual rendering. In all cases the default driver settings, together with "Printer Manages Color" significantly boosted luminance and, particularly for the Canon, Boosted saturation where the printer gamut allowed by extremely large amounts.
If you set the info panel display for LAB and 32 bits it will display high precision LAB values at the cursor. But make sure you are operating at 100% or increments of 100% zoom. Photoshop has a small bug with fractional zoom levels and precision levels deteriorate to 8 bits in some cases.
It's interesting to see just how much the L* is bumped for the defaults when "Printer Manages Color" is used. A requested L* of 50 prints at 60 in many of the Canon 9500 II settings. The gray patches at the end of the chart are fillers to make ISIS happy and they are all at LAB (50,0,0). Mouse over them to see the boost. Compare that to the custom I1Profiler profile print.
