Screen Printing Emulsions
Last night I screen printed the Non-Gelatin Emulsion that I have been talking about. I screened it onto cleaned glass plates 5x7. Overall, screen printing,for me, is easier and cleaner than draw down with a coating rod. However, using a 110 monofilament polyester screen, wet coating thickness was only 1.0-1.5 mils. The atached image shows the thinness. Also a pattern,not mesh marks, is evident. This pattern is not evident on draw-downs. The only surfactant in this emulsion is TRX-200 at 1 drop,undiluted, per 0.1 M of Ag.
I will have to order a screen with far fewer threads/inch. I recall that they go down to 24 threads/inch, or even less.
