    摘要: A method for pen drop weight calibration includes altering an image prior to printing based on the difference in printing performance of a first pen and a second pen to produce altered image data, the first pen and the second pen being disposed in the same printer. The altered image data is then printed with the printer.

    摘要: A method of printing a document using a fluid-ejection printing device includes receiving gray scale image data for the document, and identifying at least one area fill feature of the image data. It is determined whether the at least one area fill feature will be printed with a combination of different black inks and is likely to produce a visible image defect if printed in an N-pass bidirectional print mode, where N is an integer. Non-fill regions of the image data are printed using the N-pass bidirectional print mode. The method further includes automatically switching to an M-pass bidirectional print mode for printing the at least one area fill feature when it is determined that the at least one area fill feature will be printed with a combination of different black inks and is likely to produce a visible image defect, where M is an integer greater than N.

    摘要: A method for automated alignment adjustment of a printing head includes determining a current drop velocity for the printing head based on a cumulative amount of ink that was dispensed by the printing head. An alignment adjustment on the printing head is performed to compensate for a change in the drop velocity based on the current drop velocity. A computer readable medium containing executable instructions and a system are also described.
