The present invention relates to [1] a process for producing pigment-containing modified polymer particles, including the step of reacting pigment-containing polymer particles (A) containing a functional group and a compound (B) containing a reactive group capable of reacting with the functional group of the polymer particles (A) in a medium under such a condition that a ratio [(B)/(A)] of total moles of the reactive group of the compound (B) to total moles of the functional group of the polymer particles (A) is from 0.10 to 0.62; [2] a pigment water dispersion including an aqueous medium and the modified polymer particles produced by the aforementioned process which are dispersed in the aqueous medium; and [3] an ink including the aforementioned pigment water dispersion and an organic solvent. The modified polymer particles are free from formation of coarse particles upon production of pigment particles, so that an ink obtained by using the modified polymer particles can be prevented from suffering from increase in viscosity thereof when the ink is being concentrated by evaporation of water from the ink, and is excellent in rub fastness when printed on a low-water absorbing recording medium.

A redundantly printed security-enhanced document, printing method and system ensure the meaning of the information imparted by variable indicia printed by redundant printing on the document with removable scratch-off coatings. By printing the variable indicia with multiple colors, redundancy and integrity of the intended indicia is achieved. Additionally, inverted color indicia countermeasures to pinprick attacks are also disclosed. The redundantly printed document, methods and systems enhance the overall appearance of the redundantly printed document, and reduce possible consequences resulting from misprinted variable indicia. The resultant printed process color indicia maintains a grayscale equivalent level of a process color greater than or equal to the measured grayscale equivalent level of the substrate surface plus an additional contrast delta of 15%.

A shaping device, that shapes a three-dimensional object, includes an ink jet head that discharges an ink to become a material of shaping; and an ink supplying unit that supplies a pre-toned ink, which is the ink toned in advance in accordance with a color to be colored on the 3D object, to the ink jet head, where the ink jet head forms at least one part of the 3D object while coloring the one part with the color of the pre-toned ink by discharging the pre-toned ink.

A method of indirect digital printing is disclosed herein. The method employs (i) first (e.g. transparent) and second aqueous ink components (comprising colorant particles) and (ii) a target surface (e.g. hydrophobic) of an intermediate transfer member (ITM). A quantity of first ink component is deposited (e.g. by ink-jetting) onto the target surface and partially dried to produce a partially-dried layer thereon. Droplets of the second ink component are deposited onto the partially-dried layer of first ink component to form a wet, colored ink-image. Upon deposition of the droplets of the second ink component, the colorant particles from the second component penetrate into the partially-dried layer of the first ink component. The wet, colored image is dried into a tacky ink-image-bearing residue film which is transferred to the substrate. Physical and/or chemical properties of the first and second ink components as provided by various embodiments are disclosed herein.

Aqueous inkjet ink compositions are provided. In an embodiment, such a composition comprises water; resin particles; and a colorant; wherein the resin particles comprise a polymerization product of reactants comprising a monomer, an acidic monomer, a multifunctional monomer, and a reactive surfactant, the resin particles having a D.sub.(z, ave) of no greater than about 150 nm, a D.sub.(v,90) of less than about 200 nm, and a polydispersity index (PDI) of no greater than about 0.050. Methods of forming and using the aqueous inkjet ink compositions are also provided.

A manufacturing method of printed corrugated cardboard comprising the steps of: a) providing a paper liner board (23) with an ink receiving layer; and b) inkjet printing an image with one or more pigmented aqueous inkjet inks on the ink receiving layer using piezoelectric through-flow print heads (25) having nozzles with an outer nozzle surface NS smaller than 500 μm2; wherein the one or more pigmented aqueous inkjet inks contain water in an amount of A wt % defined by: wherein the wt % is based on the total weight of the aqueous inkjet ink; wherein sqrt(NS) represents the square root of the outer nozzle surface area NS; and wherein A wt %≥40 wt %.

The ratios (Wp1/Wm1, Wp2/Wm2) of the pattern widths Wp1, Wp2 to the paper widths Wm1, Wm2 are obtained, respectively, after the first drying and after the second drying (Step S109). Then, in accordance with these ratios, a range (in other words, the width) in which the back print image G2 is to be printed is adjusted in the width direction Aw (Step S204). As a result, when the double-sided printing is performed on the continuous form paper M by performing drying every time when the image is printed on each of the surfaces Ma, Mb of the continuous form paper M, it is possible to suppress the difference in the ratios of the widths of the images G1, G2 to the width of the continuous form paper M between the surfaces Ma and Mb of the continuous form paper M.

A repeatable manufacturing process uses a printer to deposits liquid for each product carried by a substrate to form respective thin films. The liquid is dried, cured or otherwise processed to form from the liquid a permanent layer of each respective product. To perform printing, each newly-introduced substrate is roughly mechanically aligned, with an optical system detecting sub-millimeter misalignment, and with software correcting for misalignment. Rendering of adjusted data is performed such that nozzles are variously assigned dependent on misalignment to deposit droplets in a regulated manner, to ensure precise deposition of liquid for each given area of the substrate. For example, applied to the manufacture of flat panel displays, software ensures that exactly the right amount of liquid is deposited for each “pixel” of the display, to minimize likelihood of visible discrepancies in the resultant display.
