A method for printing a print job including a plurality of document using a printing system includes receiving demographic information for document recipients associated with each of the documents. Printing parameters for each document are automatically determined such that an estimated total cost for printing the print job is not more than a predefined target cost. The printing parameters used for each document are determined responsive to analyzing the demographic information for the associated document recipient and estimated costs for printing the document using different printing parameters. Each document is printed using the respective determined printing parameters.

Cost-target-dependent printing using recipient demographics

A method for printing a print job including a plurality of document pages includes receiving a target cost for printing the print job. The printing system is used to print a portion of the print job including one or more document pages using an initial set of printing parameters. An estimated total cost for printing the print job is determined including an actual cost determined for printing the portion of the print job and an estimated cost for printing a remainder of the print job. A data processing system is used to automatically determine adjusted printing parameters to be used for printing a subsequent portion of the print job if the estimated total cost exceeds the target cost. The printing system is then used to print the subsequent portion of the print job using the adjusted printing parameters.

Adjusting printing parameters to meet a target cost

A method for printing an image with authentication features, including: printing a media treatment material onto a print medium in accordance with a pattern of predefined authentication features, and printing one or more visible printing materials onto the print medium in accordance with an image pattern, thereby providing a printed visible image. The media treatment material alters an interaction between the visible printing materials and the print medium so that characteristics of the interaction, such as printing material penetration characteristics, are different in image regions where the media treatment material was printed than in image regions where the media treatment material was not printed. The difference in the characteristics of the interaction between the one or more visible printing materials and the print medium causes the pattern of authentication features to be detectable.

Image authentication using material penetration characteristics

A method for printing an image with authentication features, including: printing a media treatment material onto a print medium in accordance with a pattern of predefined authentication features, and printing one or more visible printing materials onto the print medium in accordance with an image pattern, thereby providing a printed visible image. The media treatment material alters lateral spreading characteristics of the visible printing materials within the print medium, so that the lateral spreading characteristics are different in image regions where the media treatment material was printed than in image regions where the media treatment material was not printed. The difference in the lateral spreading characteristics causes the pattern of authentication features to be detectable.

Image authentication using lateral spreading characteristics

A method for printing an image with authentication features, including: printing a media treatment material onto a print medium in accordance with a pattern of predefined authentication features, and printing one or more visible printing materials onto the print medium in accordance with an image pattern, thereby providing a printed visible image. The media treatment material, the one or more visible printing materials and the print medium interact to produce surface deformations of the print medium. Characteristics of the surface deformations are different in image regions where the media treatment material was printed than in image regions where the media treatment material was not printed, so that the difference between the characteristics of the surface deformations causes the pattern of authentication features to be detectable.

A method for correcting color registration errors for a print job including one or more documents having a plurality of color planes. A color registration error model is used to predict a color registration error value for a document as a function of ink coverage characteristics for the document, wherein the color registration error model is a parametric model having one or more parameters. An image plane correction value is determined based on the predicted color registration error, and the document is printed using the determined image plane correction value.

Document registration using registration error model

A method for correcting color registration errors for a color printer that prints color image data on a continuous web of media. A color registration error model is used to predict a color registration error value for a particular in-track position as a function of ink coverage characteristics for an image region including the particular in-track position, wherein the color registration error model is a parametric model having one or more parameters. An image plane correction value is determined based on the predicted color registration error, and the color image data for the particular in-track position is printed using the determined image data correction values.

Reducing registration errors using registration error model

A method of adjusting a level of liquid to be deposited on a print media includes providing an image processing system. Image data for a page of a print job and information regarding a printing system to be used to deposit the liquid on the print media during a printing operation is provided to the image processing system. The image data for the page of the print job is converted into a bitmap appropriate for analysis of risk of excessive inking related print defects using the image processing system. The overall risk score is determined to be acceptable or unacceptable. The bitmap is released for printing when the overall risk score is acceptable. The image data for the print job page is modified when the overall risk score is unacceptable.

Print content dependent adjustment of printed liquid

A method of controlling print density in a printing system includes gathering first data from a first sensor; gathering second data from a second sensor; comparing the first data to the second data; if the first data correlates to the second data no action is required; if the first data deviates from the second data; determine a confidence level for each sensor; identify the sensor with the lowest confidence level; and take corrective action.

Method of controlling print density

A printing system using multiple printheads maintains color consistency between the printheads by printing a first color patch () with a first color with a plurality of printheads () at a first pressure and with a first pixel fill coverage. A second color patch () is printed with the first color with the plurality of printheads at a second pressure with the first pixel fill coverage. The print density of the first patch and the second patch is measured for each of the plurality of printheads and the print density for each of the plurality of printheads is compared. A pressure for each of the plurality of printheads is adjusted to compensate for differences in density between the first patch and the second patch for each of the printheads.

Color consistency for a multi-printhead system

The present invention addresses the reformatting of a digital 'ready to print' data file into a continuous tone (32 or 24 bit) file whereby discrete values in the tone range are uniquely assigned to specific binary combinations. The purpose for this transform is to facilitate further manipulation of preprocessed data. One application of the present invention is to exist as a critical piece of proofing workflow for a technology that reduces continuous tone data into a binary form representing droplet selection prior to output.

A method of determining substrate and ink compatibility includes providing a test pattern having a range of ink loading levels and including test features corresponding to at least one of text and graphics; identifying a substrate; identifying an ink set; printing the test pattern on the identified substrate using the identified ink set; selecting an ink loading level for at least one of the at least one of text and graphics using the test pattern; and generating a tone scale transformation for one or more ink colors of the identified ink set using the selected ink loading level for at least one of the at least one of text and graphics, the selected ink loading level for the at least one of the at least one of text and graphics being dependent on the identified substrate.

Color printer calibration

A system and method are provided for determining ink jet printing system parameters by selecting an appropriate linearizing transformation for application to images to be printed on a printing system for a specific substrate. These transformations can be any transformation capable of being applied in graduated increments and having a corresponding incremental visual influence on the printed output. The present invention allows the user to determine multiple parameters for the printer, including for example, tone scale correction, determination of upper ink limits, amount of under color removal, and allows the user to identify the proper ink level for optimum quality of graphics and/or text printing.
