I am a printmaker/photographer and have much experience with papers. The
paper itself is less critical than how much external or internal sizing
(glue or colloid) it has in it. Little internal sizing causes a very
absorbent sheet so chemicals are absorbed deeply and may be hard to rinse
from the fibers. Heavy sizing creates a paper where the
sensitizing chemicals sit on the surface and do not contact the paper
fibers as much. Absorbant papers such as RIVES BFK for example produce
contrasty cyanotypes whereas ARCHES EN TU CAS, a heavily sized paper,
produces a very long extended range of values in cyanotype.
