I have supervised the printing of many brochures, booklets and inserts, and there is a definite art to the printing process, from the choice of paper to the number of inks and varnishes used. There are many different grades of paper and coated paper does not necessarily have to be glossy, there is matte coated as well. Uncoated paper absorbs ink more, while ink sits on the surface of coated paper and can hold better detail and more accurate tones and color. As I stated before, I was disappointed in Steidl's work on the Leutwyler book. It was printed on an uncoated paper that really did not suit it well--the blacks were pretty compressed as well as the lack of subtle tones that I know were missing from having seen some of the images before. In the case of Robert Adams, every print I have seen from him is on glossy paper and I feel that the work should be printed on coated stock, or at least varnished to bring out the feeling of the original. I will have to go back to my copy of American Silence to see if spot varnish was used on the photos. As with coating, varnish can be glossy or matte.
