Hi All I am having a problem with my Spyder 3 spectro when reading the darker patches IE 90-100 of a 21step wedge and the 4x21 random step wedge, especially the latter. When reading the values are all over the map. 100% will read a density of 1.63�reasonable and expected. Then suddenly I will get a value of 1.01, the 1.33, then 1.50. Same on the 90 and 95 patches. Readings are totally unreliable. I can sometimes coax a good set of readings out, but it is just way too random. I have re-calibrated and re-calibrated, I have be careful about placement, and I have a backing sheet of the same paper under the patch printed paper. I have restarted the program, the computer, attached and re-attached the spectro and I keep getting crazy results in the deep shadows. Anybody have any ideas on what could be happening? Thanks for any advice/insight. John E
