    Abstract: A method of controlling surface roughness of a flexographic printing element during thermal processing is provided. An imaged and exposed relief image printing element is thermally developed to remove the portions of at least one layer of photopoiymer that are not crosslinked and cured by a) heating the at least one layer of photopoiymer to a sufficient temperature to soften uncured portions of the at least one layer of photopoiymer; b) causing contact between the at least one layer of photopoiymer and a blotting material, wherein when the blotting material contacts the at least one layer of photopoiymer, the softened uncured photopoiymer portions of the at least one layer of photopoiymer are absorbed into the blotting material; and c) separating the blotting material from the at least one layer of photopoiymer. Thereafter, a smooth material is inserted between the surface of the at least one layer of photopoiymer and the blotting material, in the alternative, after the flexographic printing element is removed from the thermal processor, a polymeric film is laminated onto the relief image printing element using heat and pressure. Based thereon, the average surface roughness of the relief surface of the- flexographic printing element can be reduced.
