RE: Pure Pt printing and solarization

Cor, Your hairdryer appears to be too close from my experience. There is no
golden absolute, but I try to stay at least 20cm away. I , when drying that
way, would dry the front of the paper for 1-2 minutes, flip it over and dry
the back side for an additional 6 minutes. After flipping the paper, you can
increase the temp to high from med. I use a rather different way to
determine soak time; absolute per paper type. Let one soak in 1 minute, dry.
Examine the paper for grain, wash off/bleeding. Soak 1:30, repeat, until 3
minutes. See if the paper shows poor black, bleeding, paper fiber, etc. In
other words, look for the best print. Waiting until the paper goes dull can
be too long. I use "to paper dull" as the way to tell when it is safe to
flip. You can use a smooth surface to do the backside dry.

I forgot the micro liter abbreviation.

Why larger? I find that small spaces can lead to quickly apparent coating
issues; too thin, too thick, etc. The smaller you work the more quick an
imbalance shows up in the print; too much FO for metal, too little,..

 Which weight paper?

..the higher steps of The Stouffer stepwedge, as well as the sky in the
image were paperwite after processing, so I guess it isn't fogging..

..Wattage I do not know, the airstream was about 10 cm away from the paper,
the air warm, but you can keep your hand in it, it's not too hot (I was
actually surprised that the emulsion can take it, I saw no fogging).

After the drying step (1-2 min) the paper was immediatly exposed

..until the shine goes to matte (say 1-2 min)...

What is a ul?

..microliter, proper symbol is ml 1/1000 part of a ml (mililiter), I use
micropipets

Try
> adding an additional drop of metal and coat a larger area.

..why a larger area?

Thanks,

Cor
