An uncured laser-engraveable composition can be applied in liquid form, as one or more portions to either: a) a laser-engraveable layer of a laser-engraveable flexographic printing precursor (plate or sleeve), or b) a printing surface of a laser-engraved flexographic printing plate or laser-engraved flexographic printing sleeve. The applied laser-engraveable composition portions can become (for example, by curing) integral parts of the laser-engraveable surface or printing surface so that the applied composition portions can be partially or entirely laser-engraved if desired. This method can be used to provide seamless flexographic sleeves. In addition, it can be used to correct or repair defects, to overwrite an image, or to provide a new laser-engraveable surface in a flexographic printing plate or printing sleeve.
