I'm not sure what I'm doing wrong here. I scanned some black and white images in RGBI mode in VueScan, converted to 16 bit greyscale. When I go to QTR to print, most of the image previews display normally, but once in awhile I get a black preview. If I convert those images to 8-bit, the image previews come up normally. Why would some 16-bit greyscale previews display normally while others not?
