Hi
I am sure there are many on this list who have had to deal with reproduction of historical documents for state or national archives. I have a client who is using a Kodak Creo iq3 scanner with OxyGen software to scan documents ranging from 19th century glass plates, albumen and silver gelatine photographs, water colour and ink illustrations, hand coloured B&W images right up to modern day emulsions.
We have built two profiles in ProfileMaker. One based on a reflective photographic target for standard emulsions and one based on a Colourchecker SG target for other reflective media. With a small amount of tweaking in Profile Editor we can get the white, grey and black patches on a X-Rite greyscale checker to match the target RGB values in Adobe RGB within one level.
My question is, is there a subject based spectral response to the scanner light source that will render each of these types of original material differently with respect to the colour checker patches. In other words, are we likely to have to build a material specific correction for different types of originals? We have found, purely visually on a small range of samples, that there seems to be one type of cast for one material and a different cast for something else.
Without going into specifics, is this an accepted issue and would a workable solution be scan all reflective originals with the same scanner profile and run a different photoshop action as a correction layer for each different type of material. This would seem simpler than having 10 different edited versions of the scanner profile, and would be easy to adjust over time as more samples are taken into account.
Thanks in advance.
