Images on Glass course – screenprinting

Today’s excitement was to learn how to screen print a photo onto glass.  Below are two images drawn by Edward Wolfe that I chose to use.  Our tutor resized our emailed photos and printed onto transparent plastic sheets ready for our class today.

Images on Glass sp1First we prepared our canvas with photo emulsion.  This was applied in a thin layer by pulling the photo emulsion upward using a trough to evenly spread the emulsion over the screen.  This is then immediately placed on a dark shelf (with no light) to dry.  This will absorb the image once exposed to light.

The final step was to remove the screen from the light box (with fingers crossed) and to take it to the sink.  As we watched the screen be showered with water, the images started to emerge.  Witchcraft!

[I was doing the ‘washing’ so didn’t get any pictures of our screen at the final stages]

We’ll all have to wait until next week to see the results.
