i have been trying to create a profile for a new paper and my spectrometer will measure about 99 percent of the target patches with no problem each target however has several patches which give me a solid yellow or solid cyan reading which is obviously wrong i re-measured it over and over again— same wrong reading — i have restarted the application —re started the computer— still those particular target patches refuse to measure correctly. i have a ticket going with datacolor support and was told that the calibration tile needed cleaning. which i did as they directed with dish washing detergent and warm water it seemed seems clean to me. i have observed that it is ever so slightly discolored i assume from contact with the spectro . but this is extremely slight barely visible. after cleaning i got the same result exactly. i am attaching several screen captures of the split measures as illustrations. also the xml profile. i am printing black and white images and the profile results in a yellow cast. not usable

i have made been making profiles for years and have not had this problem. there has been no physical damage to the hardware it is stored in its protective case between operations.

i am working on a 2008 iMac with osx 10.8.4 spiderprint 4.2.3 library version 1.85

why would only certain patches be a problem. any ideas.

thank you . . .
