摘要： A method (300) is described of determining characteristic of an ink jet printer (15). A chart containing multiple regions or patches is printed (320) on a print medium (115) using the ink jet print (15). The chart includes at least a first region printed using a first set of nozzles, and at least a second region printed using a second set of nozzles. The first and second sets of nozzles are a predetermined distance apart in the printer head of the printer (15). The printing of the first and second regions is also separated by a print medium advance operation equal to the predetermined distance. This causes the first and second regions to be aligned in the direction of the print medium advance operation. The chart is then imaged using scanner (16) chart to form a chart image. The positions of the regions appearing in the chart image are next determined (340). The spatial alignment characteristic of the printer is calculated from the distance, in the medium advance direction, between said first and second regions.

摘要： In the present invention, a conveying operation of a recording medium is controlled on the basis of a first correction value and a second correction value. The first correction value is used for correcting a conveying amount when the recording medium disengages from a first conveying roller, and the second correction value is used for correcting the phase of the first conveying roller and a second conveying roller when the recording medium disengages from the first conveying roller before the recording medium is nipped by the first conveying roller.

摘要： A recording apparatus to record an image on a recording medium using a recording head includes a first conveying roller, a second conveying roller, and a controller. The first conveying roller is positioned upstream of the recording head in a conveying direction and the second conveying roller is positioned downstream of the recording head in the conveying direction. In response to a first conveying mode being selected, the controller performs a rotational phase control in which the controller controls rotational phases of the first conveying roller and the second conveying roller such that the recording medium is conveyed by predetermined sections of circumferences of the first conveying roller and the second conveying roller when a trailing end of the recording medium passes the first conveying roller. In response to the second conveying mode being selected, the controller does not perform the rotational phase control.

摘要： There is provided an inkjet printing apparatus which can restrict each of coloring of reflected light and image clarity within an allowable range required in each of a color mode and a monochromatic mode in any of the modes to output an image with a high grade. For this end, a print duty of each of the first image improving liquid and the second image improving liquid is set in such a manner that a ratio of the print duty of the first image improving liquid having low penetratability to the print duty of the second image improving liquid having high penetratability is higher in the monochromatic mode than that in the color mode. Thereby, an appropriate ratio and an appropriate amount of appropriate kinds of the image improving liquids are applied to each of the color mode and the monochromatic mode.

摘要： For eliminating waste of ink and achieving high charging efficiency with a reduced charging time where a printing head is equipped with a second tank for reserving a predetermined amount of ink and a supply system is configured to supply ink from a first tank to the second tank intermittently, the second tank is provided with a variable internal volume. The internal volume is varied to cause the second tank itself to function as an actuator for charging ink and performing a venting process. Specifically, the internal volume is forcibly reduced to cause a reverse flow of a gas residing in the second tank along with ink into the first tank, which makes it possible to generate of waste ink that is released to the outside. A normal charging operation can be completed simply by causing a change in the opposite direction (the direction of increasing the internal volume). Relatedly, the second tank may be provided with a member for holding ink and generating a negative pressure originating from an elastic force. With connection of the first tank and the member, the pressure in the second tank is reduced to cause the member to expand, thereby introducing ink into the same. This introduction is stopped by regulating the expansion with a displaceable unit which expands when the pressure is reduced. The regulation is performed at such a position that the negative pressure generated in the member by canceling regulation is in equilibrium with an ink meniscus-holding ability of the printing head.
