Abstract: A fine particles space placement control system includes a fine particles generator configured to generate fine particles in a predetermined space by applying external energy to a liquid or a solid and an irradiator configured to remove some of the fine particles generated by the fine particles generator by irradiating the some fine particles with infrared light.

Abstract: The present invention carries out a desired image processing while using adjoining relationship between image parts. When each pair of image parts among a plurality of consecutive image parts drawn in a predefined drawing order have a difference in density value that is smaller than a threshold value and are located adjacent to one another, the consecutive image parts are recognized to constitute one combined image part. A desired image processing, such as trapping process, is carried out for the combined image part.

Abstract: A method and apparatus for automatically selecting process information for a plurality of image parts, in which a CPU, in an automatic reproduction process routine, determines a positional relation between two image parts in a page image based on figure vector data corresponding to the two image parts (S110). A rule including data such as vertical relative positions, types, and colors of the two image parts as a condition part and process information as an action part is previously stored as rule base RB in an external hard disk unit. When the two image parts are in a non-separate relation, the CPU reads attribute data of the two image parts in the non-separate relation (S150), and determines final process information by exchanging the attribute data with rule base RB (S190 and S200). The results of the processing including the final process information are then stored as a process information table TBL3.

Abstract: The present invention provides a method of and apparatus for selecting and displaying a printing process during prepress processing of one or more selected image parts which distinctively shows a target image part for the selected process, thus improving the working efficiency. When the operator moves a pointer PT to a first image part I1 on a CRT screen with a mouse 22 to select the first image part I1 (FIG. 3A), a menu button MB and a first arrow AL1 running from the menu button MB to the position of the pointer PT are displayed on the CRT screen (FIG. 3B). When the operator further selects a second image part I2 (FIG. 3C), a second arrow running from the menu button MB to the current position of the pointer PT is displayed on the CRT screen (FIG. 3D). When the operator clicks the menu button MB with mouse 22 (FIG. 3E), a pull-down menu MN including a plurality of process titles is displayed on the CRT screen.
