Embodiment Construction

[0011] For a general understanding of the present embodiment, refer to the drawings. In the drawings, like reference numerals are used throughout to refer to like elements.

[0012] As used herein, the term "imaging device" generally refers to a device for applying an image to a print medium. "Print media" may be a physical sheet of paper, plastic, or other suitable physical print media substrate for an image, whether pre-cut or roll supplied. The image forming apparatus may include various other elements such as a finisher, a sheet feeder, etc. and may be exemplified as a copier, a printing machine, or a multifunction machine. A "print job" or "document" is generally a set of related pages (typically one or more collating copy sets copied from a set of original print job pages or electronic document page images from a particular user, or otherwise related) . An image typically may include information in electronic form, which is typically rendered onto a printed medium by ...

Abstract

An imaging device includes a substantially continuous web of media; a web transport system configured to transport the continuous web along a web path; and a print station positioned along the web path and configured to apply ink to a first side of the continuous web to form images thereon. An image sensor is positioned downstream from the print station along the web path to scan a second side of the continuous web opposite from the first side. The image sensor is configured to generate a reflectance signal indicative of a reflectance of light from the second side of the continuous web. A controller is operably coupled to receive the reflectance signal from the image sensor, and to adjust at least one print process parameter based on the reflectance signal while the imaging device is performing print operations.

Description

technical field [0001] The present disclosure relates to inkjet printing, and more particularly to phase change ink printing on substantially continuous webs. Background technique [0002] Typically, an inkjet printing device or printer includes at least one printhead that ejects droplets or jets of liquid ink onto a recording or imaging medium. Phase change inkjet printers use phase change inks, which are in a solid phase at ambient temperatures but change to a liquid phase at elevated temperatures. The molten ink can then be jetted by the printhead onto the print medium, directly onto the image receiving substrate or indirectly onto an intermediate imaging member before the image is transferred to the image receiving substrate. Once the ink is ejected onto the image receiving substrate, the ink droplets solidify rapidly to form an image. [0003] In both direct printing and offset printing architectures, images can be formed on continuous media webs. In a web printing p...
