If this is conventional contact printing paper its just like enlarging
paper but much slower. At one time all of the major paper manufacturers made at
least one contact printing paper, some made two or three. The speed of these
papers varied but all required exposure to relatively intense light compared to
enlarging paper. A typical contact printing box had four or more lamps of about
60 watts for an exposure of perhaps 15 to 30 seconds. One could also use a
printing frame with a household lamp of perhaps 60 to 100 watts at a couple of
feet for exposures of several seconds to perhaps a minute.
Relatively fast contact papers were made for photo-finishing (like Kodak
Velox) and some very slow ones (like Kodak Athena or Azo) were made for general
purpose studio work.
I am interested that such paper is still made.
