How will applying only 1 coat of emulsion to the matrix affect the final print, as opposed to 2 or 3 layers?
Room Temperature: 73 Fahrenheit during the day of creating the plate; 64 Fahrenheit while printing
Researchers: Mady Lacaprucia and McKenzie Stuetzel
In this experiment, we continue to test how many layers of emulsion are needed to produce a clear and clean image. We followed the same procedure as Test 1 B for creating the plate; however, this time we only applied one layer of emulsion.
After exposing the plate, it was immediately clear that the single layer of emulsion was not going to work very well. It was very difficult to see the image on the emulsion, and it was hard to tell when enough of the extra emulsion was washed away. We printed this plate on a Praga press set to medium pressure with a catcher and a pusher, using Gamblin Bone Black ink mixed with 00 Burnt plate oil. When wiping, the plate held a lot of ink, and the image was only very slightly revealed under all of the ink.
The print is very dark not clear at all, and the original image is almost entirely lost. We think that because the single layer of emulsion was so thin, that much of the tooth of the mesh was still exposed, thus resulting in the plate holding so much ink. It is clear that only one layer of emulsion is not sufficient to produce the photographic results that we are aiming for, and we will be applying three layers of emulsion to our plates going forward.
