In a system and a method for optimizing a printing process, toner adhesion information is acquired that identifies a toner adhesion characteristic of a printed image. The toner adhesion information may identify at least one of (a) a characteristic of toner voids present in the test print, and (b) a relative indication of how easily toner may be removed from the test print. Based at least upon the toner adhesion information, a fuser pressure, a fuser temperature, or both are adjusted (“print job adjustment”). The print job adjustment is used for printing a print job prior to performing a finishing procedure on the print job. The print job adjustment improves an image quality of the print job subsequent to the finishing procedure.

An electrophotographic printer is configured to print a three-dimensional texture on a substrate by applying clear toner in locations corresponding to where texture is desired. The clear toner for texture may be applied either after, or before, other colors (e.g., CMYK) are applied to the substrate. The clear toner may be applied during the same pass as the other colors in an electrophotographic printer (10) having five imaging units (20C, 20M, 20Y, 20K, and 20X). Alternatively, the clear toner may be applied during a second pass of the substrate through the electrophotographic printer (10) if, on the first pass, all five imaging units are occupied with different colored toners. An electrophotographic printing system that includes a front-end station for scanning a document coupled to an electrophotographic printer (10) allows an operator to add texture to a scanned document.

A method of printing includes providing a printhead and providing a roller positioned downstream from the printhead. The printhead is used to selectively moisten at least a portion of the web of print media as the web of print media is guided through the printing system. The print media is caused to contact and wrap around a portion of the roller as the print media moves past the roller. The roller, having an axis of rotation, includes a pattern of recesses and ridges positioned along the axis of rotation of the roller. A second section of the roller is located between a first section of the roller and a third section of the roller as viewed along the axis of rotation. The roller includes a profile as viewed along the axis of rotation in which the diameter of the ridges located in the first section of the roller and the diameter of ridges located in the third section of the roller are greater than the diameter of the ridges located in the second section of the roller.

Often times the glossing process results in an image artifact consisting of locally lighter image a fixed distance from the lead edge as a print is glossed. This artifact is most visible in areas of medium but consistent image. The present invention provides methods for reducing this artifact.
