Yesterday I printed my first four colour (CMYK) halftone screenprint. I'm pretty happy with the result, particularly considering I printed it in my spare room with my home made exposure unit, and registered each colour using an acetate sheet. It was also quite a challenge making sure the screens were burned well enough to pick up all the halftones.
The image area is 22x27cm and individual colours are shown below as they were laid down.
