Cyanotypes & Photo Emulsion Screen Printing
------Cyanotypes & Photo Emulsion Screen Printing.
Cyanotypes:
"Sir John Herschel, who coined the word photography which literally translates as "light writing", also invented the cyanotype process in 1841. It is a variant of the photogram and commonly understood to be "blue prints." It is a simple process that gives a continuous-tone image of an intense blue color using a sensitizing solution of ammonium ferric citrate and potassium ferricyanide, otherwise known as iron salts. These iron salts, when exposed to natural or artificial ultraviolet light, are reduced to their ferrous state, producing a high contrast blue image when oxidized. Oxidation is hastened by immersion in running water, which also washes away the unused iron salts. The example here from British Algae, 1843-1853, is by Anna Atkins who produced the first botanical work on seaweeds that was entirely illustrated with photographs." http://www.alternativephotography.com/wp/processes/cyanotype/cyanotype-classic-process

"What Is Emulsion - Screen Printing Emulsions are a paste type substance, that when coated onto a mesh with a scoop coater, it dries to form a photographic type of film.
How Is It Used - When the art work is placed on the photo sensitive emulsion, and exposed to light, it creates a stencil of the art. The stencil creates a positive, of which ink can pass through onto a substrate. Emulsions are biodegradable." http://www.ryanrss.com/2EmulsionDisplay.html

Adhesive Results
On the 29th of April, around 16.00, I attempted my first trial of the stencil idea in my back-garden, on an vertical wall – East London.
The results weren't clear, no sign of a stencil was visible on the 30th of April, neither on the 2nd of May. Which led me to try out my next step on Commercial Road.
8th of May, at 23.00 I sprayed my Adhesive Stencil on a small area on the side walk of Commercial Road E1. The letter forms were directly visible at first instance, but that could be the result of the liquid settling in on the ground.
On the 9th of May, at around 18.00, the stencil was well visible except the top part which was further away from the main road.
And the same for the 10th of May, at around 11.00. The stencil is even darker, but the top part stays not so clear.

Adhesive Flyposter (Andrew's idea)
During my 3 week contract at Skew Studio I had a good chat with a colleague of mine – Andrew.
So I took on the idea discussed and have decided to apply it. This could probably be a push forward with my ideas!
