The invention pertains to a photosensitive element, particularly a photopolymerizable printing form precursor; and, a process of making the photosensitive element. The printing form precursor includes a cover sheet, a layer of a photosensitive composition, and a digital layer, or infrared ablation layer, that is adjacent to a side of the photosensitive layer. A microcell patterned is embossed onto the infrared ablation layer or an overcoat/barrier layer on the infrared ablation layer. Since the microcell pattern layer is integral with the printing form precursor, digital imaging can occur rapidly with relatively low resolution optics to form a mask without needing to also form a microcell pattern of the digital layer. The printing form precursor having the integrated microcell pattern layer facilitates the preparation of relief printing forms to have a print surface suitable for printing solids with uniform, dense coverage of ink.
