The first printing plates for binds and shares were made on blocks of dense wood. The artists first drew designs on smooth blocks, then carved the excess material away. The desired images remained as raised surfaces, which could be inked and transferred to paper.
Later, engravers developed ways to create better images by cutting into polished blocks of limestone.
Lithographs were created by squeezing ink into the grooves of the stones. This took considerable skill, but the results were better than from the woodcuts. However, the printing was still not very clear, and thus easy for forgers to copy.
