摘要： A calibration target is disclosed. The calibration target is created such that a color patch is sensitive to drop weight changes based on drop weight variations that show greater changes in color for a given change in drop weight.

摘要： Example implementations provide a controller for controlling printing of a printer, the controller comprising: an input interface for accessing an image to be printed; an image processor to identify at least one selected feature within the image; and circuitry: a. to control printing of said at least one selected feature using a respective print operation; and b. to control printing of said image, other said at least one selected feature, using a further respective print operation; c. said respective print operation being different to said further respective print operation.

摘要： A method for printing, comprising: obtaining an imaging matrix, in which each row or each column of cells is associated with at least a nozzle of a printhead, and in which each cell contains an initial value of a parameter which is related to an amount of ink to be deposited on the print medium; dividing the imaging matrix into at least two subsets of cells, such that each cell of the matrix belongs to one of said subsets; associating with each subset of cells a conversion function; obtaining a converted imaging matrix by applying to the initial value in each cell the function that corresponds to the subset to which the cell belongs; and printing using said converted imaging matrix.
