摘要： An inkjet printer, includes an ink containing a print uniformity improving polymer obtained by chain copolymerizing at least the following ethylenically unsaturated monomers: (a) a first monomer having a lowest pKa value greater than 3 and comprising a carboxylic acid group; (b) a second monomer having a lowest pKa value less than 2; and (c) a hydrophobic third monomer; together with pigment particles that are self-dispersed or dispersed with a dispersant other than a print uniformity improving polymer, and water. Such an ink provides improve print uniformity.

摘要： A method for reducing banding artifacts for bi-directional multi-pass printing on an inkjet printer utilizing a printhead with a plurality of ink nozzles includes defining different print masks to be used for leftward and rightward printing passes such that both the order of ink laydown and the timing between ink laydown on different passes are each substantially constant for a given horizontal position within the image, independent of the vertical position within the image; and printing an input image on the inkjet printer with the defined print masks using a bi-directional multi-pass print mode.

摘要： A printing method includes applying at least one of a plurality of pigmented colored inks to a receiving surface. A colorless ink is applied to the receiving surface. A majority of the colorless ink is ejected from of first nozzles on a printhead used for ejecting the colorless ink. At least 30% of an area on the receiving surface, which is passed over by the first nozzles, is covered with the colorless ink during a single pass of the printhead over the area.

摘要： A pigment-based ink jet ink set and image-recording element combination is described, wherein the ink jet image-recording element has a gloss value of at least 5 when measured at 60°, and wherein each ink in the ink set has a normalized differential specular reflectance, NΔRS(X), of less than 1.25. NΔRS(X) is defined as the maximum value within a set of NΔRS(Xn) values in which each NΔRS(Xn) is the normalized specular reflectance for a density patch of a printed test image. The printed test image consists of a series of at least eleven density patches printed such that the ink laydown of the patches increases incrementally, from no ink laydown to a maximum level generating a density of at least 1.5; and wherein NΔRS(Xn) for each patch is determined according to: N Δ R S ( Xn ) = [ R Smax ( Xn ) - R Smin ( Xn ) ] R Smean ( Xn ) where, over the visible spectral region between 390 nm and 720 nm for patch Xn, RSmax(Xn) is the maximum, RSmin(Xn) is the minimum, and RSmean(Xn) is the average specular reflectance.
