Baxter used a foundation plate which held a range of tonal effects
created by aquatint or mezzotint with steel engraving, and then
coloured the print by a series of sometimes as many as thirty wood
blocks coated in oil inks. This process, together with Baxter's
considerable engraving and printing skills, and his keen selection
of colours, brought a rich and detailed finish to his 'picture printings'.
Baxter prints were intended to reproduce oil paintings, but the
process was to prove too expensive to be popular for book illustration.
