摘要： A printed image (I.sub.t4) is produced with halftone images for respective color printers while so-called rosette moire and a color shift from an original iamge are prevented. Halftone dots (H.sub.m4, H.sub.c4, H.sub.k4) are formed in linear shapes extending in respective prescribed directions, thereby forming parallel lines with respective intervals (d.sub.m4, d.sub.c4, d.sub.k4). These extensional directions and intervals of parallel lines are so established that they effectively prevent the rosette moire and the color shift.

摘要： A recording sheet processing device includes a stack tray used, when a recording sheet gets jammed inside a subsequent finishing device, for collecting recording sheets left inside a preceding image forming device and recording sheets left inside a recording sheet feeding unit of the image forming device before those recording sheets reach the finishing device. A portion of a conveying path in the recording sheet processing device is opened so that the recording sheet that has jammed at the finishing processing side can freely fall down into a stack tray. Then, a conveying path switching claw is switched to a position for collecting subsequent recording sheets into the stack tray. Thus, subsequent recording sheets are collected in the stack tray without stoppage in conveyance.

摘要： In a head unit of a printer, a head (5A) has outlet rows (611, 612, 621 and 622) arranged along a first tilt direction and a gap between outlets in the outlet rows (611 and 612) is interpolated with a outlet in the outlet rows (621 and 622) by a slight tilt. A head (5C) adjacent to the head (5A) is tilted in a second tilt direction opposite to the first tilt direction. In the printer, a plurality of dots are formed, being aligned on a piece of printing paper in the first tilt direction by performing an ejection control simultaneously for all outlets in each outlet row of the head (5A) and subsequently a plurality of dots are formed, being aligned on the piece of printing paper in the second tilt direction by performing an ejection control simultaneously for all the outlets in each outlet row of the head (5C), to make both rows of dots continuous. Through this operation, the printer can easily perform high-resolution printing without such a complicate ejection control as to control ejection of ink for each outlet (7).

摘要： Screen patterns for respective color components are represented by arrays of unit regions. The arrays for respective color components have a same array pitch and a same array orientation. Color component images are converted into color component halftone dot images through the screen patterns. When the density of the color component images is in a predetermined range, the color component halftone dot images have a plurality of linear dot elements in each unit region. The plurality of linear dot elements extend in a predetermined direction which is different for each color component.
