Hi Mark....

On the occasions when I have had the need (usually a desperate plea) to
provide a faster turn-around for the "8x10 glossy" I will (rather reluctantly) 
use Glossy RC... butafter a gentle squeegee off (back then front) with a
somewhat aging, butstill in good condition "straight" (ie non curved)
windscreen wiper that I  purchased at the parts department of the local
Volkswagen dealership.

After the removal of excess water using the wiper, I use the household
hairdryer on "hot/high", on both back and front. To my eye, this tends to greatly reduce the 'haze' on the emulsion side that I have always found to 
be somewhat objectionable.

Ken

Ok this may be the solution to the not totally satisfied with the blacks if an RC print is best when dried in IR. The next question becomes, what is an inexpensive and practical drying source. Hanging them or placing them on a drying screen is easy, and an expensive dryer probably isn't in the budget, but if there is a normal everyday type of item that works and is effective, Im all ears.

I believe (no proof) that the top gel layer is plasticized
(melted) with the
IR radiation and hides the little OB fibers.  Hot air
can't do that.  It is
too wide spread and if hot enough burns the paper.

"One difference between ferrotyped fiber and

RC glossy

is in the blacks. RC glossy tends to have a

slightly hazy quality which

is not so of fiber. I don't know the

source of this effect "


Reason is:  Optical brightener migrates and sticks

it's little fiber

heads out the top of the Dmax area.  IR drier on

RC paper gives fantastic

Blacks.

   Kodak always recommended IR drying for best blacks.

Why does IR drying

prevent this effect?
