As part of the Today, Tomorrow, Yesterday, September project I learnt how to screen print and how to make cyanotypes.
Screen printing is a form of stencilling which was recognised in China, dating back to 960-1279 AD. Screen printing is most well known from the 1960s to present, with credit given to Andy Warhol for popularising the printing technique. Other well known artists who use the technique include Roy Lichtenstein and Robert Rauschenberg.
The cyanotype process was first invented by astronomer, John Herschel between 1792- 1871 and introduced in 1842. It was also known as the blueprint process. Herschel wanted to find a new way to copy his notes.
