Silkscreen printing was the most common method used to create posters in the 1970s. This method involves creating a stencil by exposing a silkscreen to light, then using the stencil to apply ink to the paper. Silkscreen printing can create bold and vibrant colors and is perfect for creating large posters.
Offset lithography
Offset lithography is another technique used to create posters in the 1970s. This method involves creating a metal plate with the image, then using the plate to transfer the ink to rubber rollers, which then apply the ink to the paper. Offset lithography can produce high-quality posters with intricate details.
Letterpress printing
Letterpress printing was used to create posters in the 1970s. This method involves using raised metal type to create an image, then pressing the type into the paper. Letterpress printing can create unique and tactile posters.
