摘要： PROBLEM TO BE SOLVED: To automatically measure the area and the volume of the cell of a cylinder for gravure printing. SOLUTION: A microscope 1 is used for obtaining a magnified image picture of a cell formed on a cylinder. The picture image of the cell picked up by the microscope 1 is taken into an image processing equipment 2 with a video capture board 6. On the basis of the taken-in image picture, a CPU 7 of the image processing equipment 2 automatically determines the threshold value, and obtains a binary data. After noise elimination, contour extraction and pseudocell elimination, a contour form corresponding to an actual cell is extracted, and the area is measured. From the engraving condition data at the time forming the cell and the obtained cell form or the area, the volume of the extracted cell is operated.

摘要： PURPOSE:To form the shapes of cells of the extreme shadow parts as high free flow cells of a high dot per cent (ratio of a cell area to a printing area) by forming the shapes of the cells of the extreme shadow parts in such a manner that the screen lines of an approximate arc are made into scalelike arrangement. CONSTITUTION:The shapes of the cells of the extreme shadow parts are so formed that the screen lines of the approximate arc are made into the scalelike arrangement. Then, the free flow cells having high dot per cent are obtd. and the ink in the cells flows one after another into the cells on the downstream side until the ink is admitted about 100% into the cells if scraping of the ink is executed by a doctor. An improvement in density is then resulted. The shapes of the cells in highlight parts are formed to be long holes which are increasingly longer in the relative ink scraping direction of the doctor. These long holes are so formed as to be gradually longer as the dot per cent increases. As a result, the ink is admitted about 100% into the cells of the highlight parts if the scraping of the ink is executed by the doctor. The density is thus improved and the various gray level gradation of the highlight parts is improved.

摘要： PURPOSE:To improve vacuum adhesivenss by coating a specific coated film forming resin liquid on a transparent base and drying the coating to form a photosensitive layer having micro-ruggedness on the surface then printing a halftone screen thereto and subjecting the same to a developing process thereby forming dots. CONSTITUTION:The coated film forming resin compounded with a diazo photosensitive dye and pulverous org. or inorg. powder is coated on the transparent base and is dried to form the photosensitive layer having the micro-ruggedness on the surface; further the halftone screen having the continuously changing density is printed to the photosensitive layer, then the photosensitive layer is subjected to the developing process to form the dots. The transparent plastic film is exemplified by a polyester film, PE film, etc., among which the relatively inexpensive polyester film having the excellent dimensional stability is more preferable. The coated film forming material is exemplified by a vinyl acetate/ acrylic acid copolymer, vinyl acetate/vinyl pyrrolidone copolymer, etc. The discriminating property of the front and rear is thus improved and the vacuum adhesion in the plate stacking stage is made quick and uniform.
