A new Kodak RC paper called Polyprint came out about six months ago, but
the straight dope about how it differs from Polycontrast RC lagged behind
the appearance of the paper.  I have been using it and like it.
Polycontrast RC has developing agent in the emulsion, so that as soon as
it is immersed in the high pH developing bath, the image comes up.  After
thirty seconds, you don't notice much more apparent development.  Polyprint
is like fiber papers.  The first vestige of an image in 30 sec.
Considerable darkening between one and two minutes, and a noticeable
additional effect between two and three minutes.

On drying fiber paper:  I love the Kodak blotter roll.  It is a scam to
have to pay $25 for what is in effect a long sheeting of blotting paper, a
long sheet of linen finish paper, 2/3 of a corrugated board, and a
cardboard cylindrical core, but it does the most wonderful job.  No crinkly
edges and the prints come out curled emulsion side out.  I remember when
you could get them for $5!
