A discharge defect of a nozzle in an apparatus that forms an image on a medium by discharging liquid from a liquid discharge head based on image data is accurately detected. A discharge defect of a nozzle is detected by comparing data (reference data) of a reference image with read data obtained by reading an output image. In this case, a mark for matching the read pixel and the nozzle position with each other is recorded on the medium, and the correspondence relationship is specified by reading the mark. In addition, data items that are converted to have the nozzle resolution by performing a filtering process corresponding to the human visual characteristics for both the data of the reference image and the data of the read image are compared with each other, thereby detecting a discharge defect of a nozzle.

Threshold matrixes for a C-separation and an M-separation of main colors are used to convert a continuous-tone image subjected to color separation into dot patterns for the C-separation and the M-separation. The dot patterns are binary images in which no screen ruling or screen angle is defined. Then, a color image is reproduced by overlaying the dot patterns for the C-separation and the M-separation. When the dot patterns for the C-separation and the M-separation are converted into patterns in the frequency domain, main frequency components obtained by the conversion have a substantially-constant predetermined pattern frequency for all angles, and the intensity distribution of the main frequency components is varied based on the C-separation and the M-separation.

A dot pattern with a plurality of pixels representing a two-dimensional image is formed on a printing plate material by applying laser beams, which are turned on and off for each pixel depending on dot pattern data, to the printing plate material in a main scanning direction, while the laser beams are moved in an auxiliary scanning direction that is orthogonal to the main scanning direction. A threshold matrix having an array of thresholds is obtained for generating a dot where the degree of a variation of the dot periphery length in a main scanning direction is smaller, i.e., a dot where the dot periphery length in the main scanning direction has a smaller standard deviation.

Ultradispersed ones of primary particles of nanometer-sized carbon are obtained by applying a wet-type milling method and/or a wet dispersion method to an aggregate structure of the primary particles to overcome van der Waals forces, by which forces the primary particles are held together to form the aggregate structure, whereby the ultradispersed primary particles are obtained in a colloidal dispersion on a large-scale basis at low cost without using any additive. In a method of manufacturing the ultradispersed primary particles, the wet-type milling method is carried out in a ball mill, preferably in combination with a high-energy ultrasonic-wave process carried out in a dispersing medium such as pure water, whereby a colloidal solution or slurry with a low-concentration of the primary particles ultradispersed in the dispersing medium is obtained.

A threshold array having an array of thresholds for reproducing a gradation with a dot pattern as a clustered pattern of dots each made up of one or more blackening pixels is corrected. At least one non-contact point candidate position to be turned into a non-contact point is determined among contact points of the dots. Then, at least one contact point candidate position to be turned into a contact point is determined among non-contact points of the dots at the given gradation. Thereafter, the threshold array is corrected by switching around a threshold for the non-contact point candidate position and a threshold for the contact point candidate position, whereby the layout of contact points of the dots can be corrected.

Halftone image data is generated according to a threshold array in which thresholds T up to a given gradation have been determined, and candidate pixels to be blackened are then determined. Then, a low-frequency component extractor extracts low-frequency component data from density image data which simulates the density of the halftone image data corresponding to an output image from an image output apparatus. A particular frequency component dividerdivides the extracted low-frequency component data into particular frequency component data for intensifying the low-frequency components, and blackening candidate pixels for intensifying the particular frequency components are excluded, thus narrowing down candidate pixels. The positions of thus determined blackening candidate pixels are determined as the positions of thresholds for a next gradation.
