Default How I coat paper

Here is an example of how I coat paper sheets. The example is using Strathmore Smooth paper on an 11x14 sheet to achieve an 8x10 usable size.

The emulsion used actually is a dye made to simulate an AgBrI emulsion that is orthochromatic. This is just approximate, but how it would look coated at the levels used for film, not paper.

I did this so that you can see the coating on the paper.

They are, in sequence, tempering the emulsion and coating blade, charging the blade with emulsion as it rests on the paper, and inspecting the finished sheet for defects.

I have a set on film coataing and plate coating coming soon.
