Providing that the paper is pre-shrunk, and the sizing is thorough
(that's why I size and dry, then size again) registration is no more of
a problem than usual - it's always tough because the paper starts to
curl after multiple exposures and its tough to get it to lie flat under
the negative. But pre-shrinking in warm, almost hot, water is
essential because otherwise, registration is impossible.
