Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J 29/38

US Classification:

347 14

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.

International Classification:

B41J 29/38

US Classification:

347 9

Abstract:

A system and a method for improving the quality of prints using a print mask for a printer having at least one printhead with a plurality of dot forming elements arranged in complementary dot forming element groups by section to prevent artifacts by compensating for bad dot forming elements on a print head. The method including the steps of identifying each bad dot forming element, identifying and setting up a threshold for each complementary dot forming element group corresponding to one or more bad dot forming elements, and creating a compensation print mask having one or more intermediate print sections by reassigning printing duty cycle from the bad dot forming elements to their respective complementary dot forming elements before printing using the compensation print mask.

US Classification:

347 5, 358 18

Abstract:

A method of using an inkjet printer to print an input digital image containing at least one color channel having a plurality of rows and columns of pixels sampled at a first resolution, each pixel having a code value, includes partitioning the input digital image into a set of spatially non-overlapping blocks; computing an average code value for each block responsive to the pixels in the input digital image that correspond to the block; computing an image quality score for each block responsive to the average code value for that block; determining a print mode in response to the image quality scores for the set of blocks; and printing the image on the inkjet printer using the print mode.
