Title: Recording method
Inventor: MOROHOSHI NAOYA
IPC: B41M5/00
Filed: 1986-02-07
Abstract: PURPOSE:To simultaneously enhance color forming properties, ink absorptivity and strength of a coated layer, by incorporating spherical silica into a recording material to be recorded by adhering droplets. CONSTITUTION:Spherical silica is incorporated in an ink-receiving layer provided on a base of a recording material. Particularly preferably, the spherical silica is a porous synthetic spherical silica having an average particle diameter of 2.0-8.0mum in which particles in a particle diameter range of (average diameter) + or -1.5mum constitute not less than 60% of the total amount. Namely, the silica particles are spherical in shape, are high in uniformity of the particle diameter of secondary particles, and have a porous structure. Therefore, when the spherical silica is incorporated in the ink-receiving layer, voids between the particles optimum for absorption of an ink and a microporous structure suitable for adsorption of a dye can be obtained, both ink absorptivity and the strength of a coated layer can be enhanced while maintaining the excellent color development properties of images formed.

Title: White level correcting method for image reader
Inventor: KAJI YUKIO
IPC: G06T1/00
Filed: 1991-02-20
Abstract: PURPOSE:To detect a ground color without an influence of holes or cuts in the front end of a document by averaging values of picture elements of one or several lines in the front end of the document and using the average value to correct the ground color of the absolute white level. CONSTITUTION:Not only the difference between the white level and the ground color detected for each picture element but also the average value, which a CPU 24 calculates, of picture element values of one or several lines in the front end of the document stored in a memory 23 is inputted to a correction table 15. This average value is used to correct the absolute white level to generate the white level for document read. Consequently the influence of punched holes or cuts in the front end part of the document is almost all eliminated by averaging of picture element values on lines because of a low proportion of their occupation on lines even if they exist.
