Abstract
A method for making plates from photopolymer sheets which have previously been exposed to ultraviolet radiation, to convert the sheets into printing plates for flexographic, letterpress or dry-offset printing, includes brushing the exposed faces of the sheets with a brush assembly having a row of flat brushes with generally rectangular brushing surfaces. The brushes each undergo a movement of horizontal rotation and the brush assembly also undergoes at least one movement of reciprocating horizontal translation. Each brush is offset by 180° in its horizontal rotation with respect to the immediately adjacent brush, or to the two immediately adjacent brushes in the row. Also disclosed is an apparatus for performing the method.
