A mask element for flexographic printing is provided. The mask element can be used for preparing a mask that has a mask image. The mask element can include: a transparent polymeric carrier sheet; a barrier layer on the transparent polymeric carrier sheet, wherein the barrier layer comprises non-crosslinked nitrocellulose; and an imaging layer on the barrier layer, wherein the imaging layer includes a non-silver halide thermally-ablatable material comprising non-crosslinked nitrocellulose, carbon black, and an infrared (IR) dye. In some aspects, the mask element further includes a transparent overcoat layer on the imaging layer. The mask can include: imaged regions in the imaging layer, wherein the imaged regions have optical apertures that are substantially devoid of the carbon black and non-crosslinked nitrocellulose thereof; and non-imaged regions in the imaging layer, wherein the non-imaged regions have the non-crosslinked nitrocellulose, carbon black, and infrared dye.
