In accordance with various embodiments, there are printing apparatuses and methods of enhancing an image quality on a media. The method of enhancing an image quality on a media can include providing an ink-based halftone image on a media, wherein the halftone image can include an amount of noise. The method can also include depositing a transparent overcoat layer at least over the halftone image, wherein the transparent overcoat layer can include a major amount of cross-linkable resin and a minor amount of a photoinitiator. The method can further include embossing the transparent overcoat layer to form an embossed micro-structured overcoat layer and curing the embossed micro-structured overcoat layer to form the micro-structured overcoat layer, such that the micro-structured overcoat layer reduces the amount of noise.

A system to combine the transfer and fixing xerographic steps of a xerographic printer into one, as well as to eliminate the need for an electrical field for transfer. The image is transfixed directly from a photoconductor to the paper or other suitable substrate. Appropriate pressure is applied during this step to cold-pressure fix the toner on the paper, taking into account the type of substrate and type of toner. The cold pressure transfix can be done either directly from a photoreceptor, without an intermediate transfer belt (ITB), eliminating all electrostatic transfer subsystems and a fusing operation. Alternatively, for engines with an intermediate transfer belt (ITB), the cold pressure transfix could replace a needed second transfer and fuser system.
