Abstract
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.
