This discussion has been excellent...Photoptimist, TonyW, and Biz-engineer. Up to the point of non-published proprietary information, we have a nice breakdown of the physics, mechanical, and optical considerations for levels of viewing pleasure for printed images. I have filled in some information gaps in my understanding. I am a chemist by education and 39 years working as an Industrial Chemist. I tend to think about spectroscopy and spectral identities such as chromaticity curves, color wavelengths, and spectral lines which are the physical basis of color and its manipulation limits. Color is a spherical world and color "systems" or descriptions are line segments or curves transecting that sphere. When the color palette is chosen that is used to "mix" colors to result in colors generated in the image and displayed by the ink system, the physical/mechanical system must be adapted to handle how light interacts with the chosen color palette. And that does include the dot matrix of the printheads, substrate (paper, rag, canvas) architecture, viewing light temperature, viewing light angle, distance of the viewer, cover quality (polymer coatings for canvas, metal prints, or framing glass or plexiglass, with UV management, reflection control, and other considerations). Ultimately, the quality of the viewing pleasure rests with the individual perception, eye to brain translation, neural fill-in, and artistic attribute (left brain vs right brain). Thanks for your contributions to our overall knowledge. FYI, I use bicubic image resizing algorithm base software with good results.
