ABSTRACT:
An apparatus and method for reducing shade effects associated with print quality control, typically generated while viewing or imaging a partly transparent/partly opaque printed material against a light diffusing surface. The reduction in shade effects is by illuminating the printed material from above and viewing or imaging the printed material against a multiple volume light scatterer, thereby redistributing at least part of the light, such that at least part of the scattered light illuminates shaded regions in the image or view obtained.
