When the polymer is dissolved, the mixed solution is filtered. The filtrate is the water-based ink. The water-based ink is sprayed via a computer-to-plate machine onto a surface of a metal substrate (which may be an aluminum plate, a zinc plate, or a copper plate) to form a graphic region. A printing plate allowing for computer-to-plate printing is acquired after solidification.
