I've seen this question posted on APUG before and I still don't have the answer. I bought a used X-Rite 810 densitometer. It comes with a reflection calibration tablet, but it's missing a transmission step wedge. Does anybody know the densities of the particular patches on the step wedge? I looked at the manuals online and they don't specify the densities. Anything piece of information will be helpful. Thanks in advance
