Other colorists have explained the problems with art reproduction, so I will not repeat all of them. The most important item when dealing with artists is to explain the limitations of the reproduction process and to set the correct level of expectations. I will explain how I handled this situation when asked to reproduce art. I would work with the artist and explain that it is impossible to reproduce the spectral reflection characteristics of oil paints or other pigments with inkjet pigments. Given this, the print, at best will only match the original in one ambient lighting environment. I would also explain the problems with lighting the original with respect to UV and fluorescence. I would then explain that I was going to produce a "rendering" of his original. I would adjust the reproduction to give the best rendering of the subject matter. Of course this is subjective and in the control of the print maker. When I did this with one artist, he said that he liked the colors in the rendering better than his original. It is all about setting the correct expectations. Ray Maxwell
