Abstract: A binary pagewidth printhead without substantial grayscale capability includes an array of adjacent printhead segments that are distributed across the pagewidth printhead so that adjacent segments overlap at their ends by a predetermined distance. A plurality of printing pixels extending along each segment have physical differences that effect substantially non-uniform transfer functions that decrease toward the ends of segments over the overlap distance. The physical characteristics of the printing pixels are such the their transfer functions vary linearly over the overlap distance. The physical characteristics of the printing pixels may be such the their transfer functions increase monotonically from a small value at the ends of the printhead segments to a larger value away from the ends of the printhead segments. The physical characteristics of the printing pixels in a central portion of each segment are preferably uniform such the their transfer functions are constant over the central portions.

Abstract: Description of an inkjet printing method, whereby a second and optionally a third and/or additional ink(s) is/are printed on top of each other or immediately next to each other, whereby (i) the first ink contains a coloring substance precipitable by a precipitation reagent, (ii) the first or the second ink contains the precipitation reagent in temporarily passivated form, and (iii) the first, second or third ink contains an activator for the temporarily passivated precipitation reagent, with the proviso that the temporarily passivated precipitation reagent and the activator are not present in the same ink. The method prevents or reduces the problem of mixing or running into each other of two inks at their border lines. The temporarily passivated precipitation agent can be a complexed multi-valent metal ion, which is displaced from the complex by the activator.
