self coat




Starting to get more consistent results from self coating paper for cyanotype!
The process involves mixing a couple of chemicals and then painting it on to paper, specifically non-acidic watercolour paper. Of course that has to be done in a fairly dark room… There is lots of info online with regards to chemicals, paper type etc and how to calibrate exposure.
One tool that is making it easier for me is I now have a contact printing frame, made by local genius Brian Scadden.


While researching I found a contact printing frame on an Australian website, but as it has glass in it I was not keen to have it shipped to NZ. So I asked around and Brian offered to make me this one.
The design is simple but excellent – I place my negative or transparency on the glass, then a sheet of cyanotype paper, check the alignment, clamp the back shut and can then put it under UV light or the sun, and expose it.

The back opens in two halves, so its also possible to check exposure without moving the alignment…



Some experiments are less successful than others, for example this one I tried “doing a Jackson Pollock” and applied the cyanotype chemicals via splatter painting… It is underexposed, but a sharp image printed into splatter has potential, just not this time..


Self coating cyanotype paper creates far more interesting prints with deeper blues and texture from the paper contributing, as well as the option to ‘paint’ the chemicals on. I like the brush strokes, I’m using Japanese hake brushes and once I iterate a few dozen more times I should start to have a bit more control over the process…
