What is the procedure for double coating Platine Paper for Pt/Pd printing?.
I have understood that the second coat could be diluted with distilled
water. How much drying is needed between the first and second coats? What
are the advantages of double coating. What are the effects on a step wedge
contact printed between one and two coats? it obviously expensive doing two
coats on large format. Feedback?
Second question : In the sodium dichromate method of contrast control, is
any restrainer such as Hydrogen peroxide needed for the KOx #0 solution,
that is no drops of sodium dichromate.? Is the evident grain of the pure
Kox solution paper dependent?
