    摘要: At least one environmental condition that affects color of a printed image is automatically sensed, just before printing. That information is then used to modify printer operation, to compensate specifically for effects of the condition on color. This is preferably accomplished using a transfer function calculated just before printing. Also preferably taken into account is a principal color-calibration profile, not prepared just before printing but rather substantially constant. If a replaceable colorant-placing module is in use—selected from many such modules—and the particular module has a characteristic property (such as drop weight or age of an inkjet pen) which affects the color of printed images, then preferably information about that property of the particular module is also automatically used to modify printer operation, to compensate for effects of the distinctive property on color. Interactive effects of environmental conditions and module characteristics are preferably also accounted for. If the printing medium in use has a sensitivity to excessive colorant deposition of colorant, at least one environmental condition that affects that sensitivity of the medium to excessive deposition is also automatically sensed, just before printing; and this information is then automatically used to modify printer operation, to limit the amount of colorant deposited. Instructions for automatic operation are placed in a nonvolatile device at the time of manufacture. Sensitivity data are empirically assembled from test patterns and used, preferably in algebraically signed form in regression calculations, to find coefficients for use in polynomials used to calculate the transfer functions.

    摘要: Method and apparatus (10, 102) for continuous inkjet printing wherein a first continuous stream of ink droplets (66) traveling above a first flow path (48) is used as a mask for colliding with a second continuous stream of ink droplets (70, 72) traveling along an second, intersecting flow path (56) en route to a receiver (12) on which an image is to be printed. Selective droplets (72) of the second droplet stream are timed and of a size to pass between and avoid the masking droplets (66) of the first droplet stream so as to travel on and impinge the receiver (12) for forming the image thereon. The colliding masking and masked droplets (66, 70) are larger than the selected printing droplets (72) to facilitate collision. The smaller printing droplets (72) facilitate sharp pixel formation. The apparatus is compatible with low voltage CMOS print head systems and provides reliable operation, yet is relatively inexpensive to manufacture compared to other continuous ink jet print head constructions.

    摘要: A printing head includes a first type nozzle groups for ejecting respective inks of a first ink group, and a second type nozzle group for ejecting respective inks of a second ink group. The second type nozzle group includes twice the number of nozzles in the first type nozzle group. On the forward passes of the main scanning, ink droplets are ejected from both the first type nozzle group and the second type nozzle group. On the reverse passes of the main scanning, ink droplets are ejected from only from the first type nozzle group. With respect to the first type nozzle group, the ejection timing of the ink droplets is corrected on the reverse passes of the main scanning on the basis of a specific correction value for dot misalignment.

    摘要: An apparatus for printing an image is provided. The apparatus includes a source of ink. A droplet forming mechanism is operable in a first state to form droplets from the source having a first volume traveling along a first desired path and in a second state to form droplets from the source having a second volume traveling along the first desired path. The droplet forming mechanism is positioned proximate the source. A first system selectively applies a first force to the source such that selected droplets formed from the source by the droplet forming mechanism travel along a second desired path. The first system is positioned proximate the source. A second system applies a second force to the droplets traveling along at least one of the first desired path and the second desired path. The second force is applied in a direction such that the droplets having the first volume diverge from the droplets having the second volume.
