This was a challenging poster to design and to screen print for many reasons. The sharp edges of the clean lines are hard to maintain through a large run due to bleeding, paper expansion, and smudging.
The colors are created by multi-level overprinting, where the colors are deliberately mixed to be semi transparent and they overlay each other in certain areas to create additional colors. The paper is black, so when a color hits the paper directly, it appears darker and less saturated and the lighter colors are created by building up the layers.
The overprint nature created another level of difficulty, because the colors had to be both transparent and bold, so a lot of time had to go into color proofing and mixing. Also, due to the overprinting, the different layers had to be registered very tightly.
