Problems with IT8 calibration
PostPosted: Wed May 30, 2007 1:52 pm
Recently I upgraded to Silverfast AI 6.5. Since installing it I've just tried to recalibrate my scanner (Microtek 9800). The software doesn't recognise my Kodak calibration card, presumably because it doesn't contain a barcode. So it asks me to locate the IT reference. I navigate to R2200401.Q60 in my IT8 Reference folder. This is the reference I've used successfully before upgrading. I open it and get a message that ICC reference already exists. Overwrite it? I cancel this so that I can position the mask correctly over the card. Once the mask is correctly positioned, I hit OK and this time round I click OK to overwrite the ICC profile. I get a message saying calibration succeeded with an average delta of E nan. Now my scanner scans everything as pure black. What's going on here?
