The system gives images with excellent gloss, coalesence, and image quality.
Abstract:
A method for printing input digital images using an inkjet printing system having a first and second drop ejector arrays for ejecting drops of a particular ink, wherein ink paths supplying drop ejector arrays have different length projections. The method comprising printing a first combined number of ink dots using the first and second drop ejector arrays during first and third time intervals where the printhead is accelerating and decelerating; and printing a second combined number of ink dots using the first and second drop ejector arrays during a second time interval where the printhead is moving at a substantially constant velocity, wherein the percentage of ink dots that are printed by the drop ejector array having a longer length projection is less than 40% of the corresponding combined number of ink dots in at least one of the first or third time intervals.
Abstract:
A method for automatically compensating for scanner metamerism errors associated with scanning input images using a digital color image scanner, wherein the input images can be on a variety of different input media having colorants with different spectral characteristics, comprising scanning an input image on a digital color image scanner to produce a scanned image; determining one or more estimated color balance error values in a color balance parameter space by analyzing the scanned image using a color balance analysis algorithm; assigning an input medium from a set of possible input media for the scanned input image in response to the estimated color balance error values; selecting a scanner metamerism correction color transform associated with the assigned input medium; and applying the selected scanner metamerism correction color transform to the scanned image to produce a corrected image compensated for scanner metamerism errors.
Abstract:
A method of determining and applying a protective ink amount to be printed in addition to a plurality of colored ink amounts to make colored pixels in an image including determining the protective ink amount such that the sum of the protective ink amount and the colored ink amounts is greater than or equal to a minimum ink amount necessary to provide adequate durability for the image, and applying using an inkjet printer the colored ink amounts and the protective ink amount to make the colored image pixels.

Abstract:
A method of printing with an inkjet printer, the method includes moving the carriage along a first carriage scan direction while the second drop ejector array ejects drops of anti-curl solution onto the portion of recording medium providing a delay time that is greater than 15 milliseconds after the second drop ejector ejects drops of anti-curl solution at a given location on the portion of recording medium and before printing with the first drop ejector array moving the carriage along a second carriage scan direction while the first drop ejector array ejects drops of ink in an image-wise fashion onto the given location of the portion of recording medium.
