Excellent review. You mentioned that this is Contact Image Sensor (CIS) and if its 1mm off the glass it will be blurred. How do you manager this with watercolour paper is not likely to be 100% flat due to the paper buckling a bit. Even the best of the papers like Arches will eventuate is a surface that is not 100% flat.
