Abstract: Provided is a printing apparatus including a head and a control unit. The head ejects, onto a printing medium, an image forming liquid for forming an image and an ancillary liquid ancillary to forming of the image performed by the image forming liquid. The control unit performs control so as to cause the head to perform a first operation of ejecting the image forming liquid onto a first region of the printing medium, and a second operation of ejecting the ancillary liquid onto a second region of the printing medium, the second region being different from the first region. Further, the control unit performs control so as to cause the head to perform the second operation in an anterior pass and perform the first operation in a posterior pass.

Abstract: A recording paper supply mechanism 20 of a roll paper printer 1 has a roll paper holder 26 that holds the sides of a paper roll 12 on the transverse axis X at a position above Z1 the roll paper receiver 25. A delivery roller 22 is disposed above Z1 the paper roll 12 on the roll paper receiver 25. A detection unit 24 has a emitter 24A and photodetector 24B position so a detection beam L travels diagonally below the delivery roller 22, and the detection beam L intersects the path A of paper roll 12 movement when rising toward the delivery roller 22. A near-end state can therefore be detected based on output of the detection unit 24 even when the paper roll 12 is raised by force pulling in the delivery direction.

Abstract: A method for controlling an electrophotographic printing system to print digital image data for an image region. An image region database stores data characterizing a plurality of reference image regions, each reference image region having one or more associated system control parameters that are appropriate for use in printing the reference image region. The system control parameters can include parameters related to correcting color registration errors. The image region to be printed is compared with the reference image regions in the image region database, and a similar reference image region is selected. The image region is printed using the system control parameters associated with the selected similar reference image region.

Abstract: When an inkjet printer ejects ink onto a recording medium on a go path and on a return path of a carriage, if ink cannot be ejected onto the same position on the go path and on the return path, image quality becomes poor. Test patterns with shifted ejection timing are hitherto recorded on the recording medium, and appropriate timing is input as a correction value. There is also an inkjet printer which automatically reads a test pattern, but the test pattern is recorded without consideration of a state of a head, and thus, accuracy is low. Therefore, a test pattern having a long period and a test pattern having a short period are recorded, and densities of the test patterns are read by a sensor. An extremum candidate is determined from the test pattern having a long period, and rough adjustment is made first. Then, in a region around the extremum, an extremum is determined from the test pattern having a short period.

Abstract: An embodiment of this invention solves a problem about a precision drop of registration adjustment of a range detection method due to variations of a registration state depending on a position associated with a carriage scanning direction. In that embodiment, reference and adjustment patterns are formed to be juxtaposed in a nozzle array direction to detect a position shift between patterns in the main scanning direction. In this case, coarse registration adjustment is executed by the range detection method, and its adjustment result is applied to a printing apparatus. After that, fine registration adjustment is executed by a density method, and results of the two adjustment methods are finally reflected.
