We capture colour images printed on paper through a CCD camera. How can we eliminate the scattering effect of the paper and to account for optical dot gain?
Essentially you can’t. The scattering and optical dot gain happen before the image is captured and there is no going back. You could try some image enhancement in a program like Adobe Photoshop, but that would be an aesthetic judgement on success since getting back to original CMYK data used to make the print would depend on far too many variables (ink, paper, separation algorithm, camera sensors, etc.) to make it feasible to automate.
