Abstract
An improved apparatus for thermally developing a flexographic printing element to reveal a relief image on the surface and a method of using the apparatus to develop a flexographic printing element. The apparatus typically comprises means for softening or melting a crosslinked photopolymer on the imaged and exposed surface of the flexographic printing element; at least one roll that is contactable with the imaged surface of the flexographic printing element and capable of moving over at least a portion of the imaged surface of the flexographic printing element to remove the softened or melted non-crosslinked photopolymer on the imaged and exposed surface of the flexographic printing element; and means for maintaining contact between the at least one roll and the imaged and exposed surface of the flexographic printing element. A layer of resilient compressible material is positioned between the flexographic printing element and a supporting conveying means. The means for softening or melting non-crosslinked photopolymer on the imaged and exposed surface of the flexographic printing element comprise a heater positioned adjacent to the imaged surface of the flexographic printing eleme…
