PURPOSE: To determine easily at which dot area per cent printing is to be performed by comparing a conversion table for color information-dot area per cent and the information on the respective colors of an object to be measured, selecting the color information most approximate to the color information of the object to be measured and inputting the combination of the dot area rate corresponding to the same to an external device. CONSTITUTION: A conversion table for color-information-dot area per cent with the combination of color information and the dot area per cent corresponding to the color information on plural colors of color separating plates is preliminarily stored in a storage means 10, and the data in the color information determined by a means 20 for measuring the color of the object to be measured is once stored in a storage means 30. A means 40 for selecting the color information compares the color information of the conversion table for the color information-dot area per cent and the color information of the object to be measured and selects the color information most approximate to the color information of the object to be measured from the former. The combination of the dot area corresponding to the selected color information in the above-mentioned way is inputted to an external device by a means 50 for inputting the dot area per cent. The dot area per cent of each color is easily inputted to the external device in the case of expressing the colors of the object to be measured by printing ink in the above- mentioned manner.

PURPOSE:To determine easily a dot area per cent by comparing a conversion table for color- density-dot area per cent and a combination of the respective color densities of an object to be measured, displaying the interpolated dot area per cent if both do not coincide and displaying the combination most approximate to the conversion table when both do not coincide. CONSTITUTION:A conversion table for color density-dot area per cent corresponding to the combination of the color densities and the combination of the color densities of plural colors of color separating plates is preliminarily stored in a storage means 10, and the data on the combination of the color densities determined by a means 20 for measuring the color density of an object to be measured is once stored in a storage means 30. A means 40 for selecting the color density compares the combination of color densities in the conversion table for color density-dot area per cent and the combination of color densities of the object to be measured and selects the combination most approximate to the combination of the color densities of the object to be measured among the former. The combination of the dot area per cent corresponding to the combination of the color densities selected in the above-mentioned way is subjected to interpolation by a vector method by a means 60 for interpolating the dot area per cent and is displayed by a means 70 for displaying the dot area per cent. The dot area per cent of the ink of each color is easily determined in the above-mentioned way in the case of expressing the color of the object to be measured. | ||||||
223 | Image recording system | JP18302181 | 1981-11-17 | JPS5885434A | 1983-05-21 | KAWAMURA NAOTO |
PURPOSE:To obtain a prescribed screen angle, by shifting a position of starting memory reading in comparing lightness of one image element of an input image signal with a threshold matrix memory consisting of KXL fine image elements. CONSTITUTION:To allow each lattice point of a fine image element constituting the center of a dot to form a uniform lattice space, the relationships of m=n= alpha, i=j=-alpha must be satisfied when the position of the fine image element located at the center of the neighboring image elements in the horizontal direction is shifted by (m) in the horizontal direction, and by (n) in the perpendicular direction, and the position of the fine image element located at the center of the dot of the neighboring elements in the perpendicular direction by (i) in the horizontal direction and by (j) in the perpendicular direction. When K=L, though these relationships are satisfied, each lattice space is not always made uniform. A sheet of color image can be formed by operating 3 cycles of developments, i.e. 3 rotations of a photosensitive drum corresponding to 3 primary colors of a color image and transferring these 3 images to one sheet. | ||||||
224 | Original plate for printing and its production | JP16197081 | 1981-10-13 | JPS5863939A | 1983-04-16 | KAMETANI SHINICHI |
PURPOSE:To obtain an original plate for printing which wedges itself less into corrugated boards, permits printing on non-woven fabrics as well and provides sharp prints by interposing a negative film and a screen having many spotlike light transmittable part of specific density between a light source and a photosensitive resin and exposing the same. CONSTITUTION:In the stage of exposing the parts of a photosensitive resin 5 to be formed with printing areas 1 and hardening said parts, a negative film 6 imprinted thereon with characters, symbols, patterns, etc. to be printed and a screen 7 having many spotlike light transmittable parts are interposed between said resin and a light source 8, and light is projected from said light source to the resin 5. If the unexposed parts of the exposed resin 5 are washed away, an original plate for printing having fine dots 3 in the printing areas 1 is obtained. On account of the presence of the screen 7, many fine dots are formed in the printing areas at 100-300 lines/in line number, 3-50% surface density with respect to the printing areas and 5-200mu height. | ||||||
225 | Correcting circuit in measuring device for halftone dot area rate | JP16809680 | 1980-12-01 | JPS5793347A | 1982-06-10 | YONEKURA YASUHIRO |
PURPOSE: To measure dot area rates with high accuracy by making the light transmittance or light reflectivity of the dots to be measured independently correctable at 50% point in photomechanical process. CONSTITUTION: An inversion amplifier Q 5 and resistances R 51, R 52 are combined with a folding point correction circuit consisting of a Zener diode Dz and an inversion amplifier Q 4. The respective outputs of the amplifiers Q 4 and Q 5 are synthesized with a variable resistor R 6 and are outputted. Hence, in the relation of the transmittance or reflectivity of the object to be measured dotted in the intermediate process of a photomechanical process and the measured value of dot area rates, only the 50% point Ez is made arbitrarily and independently correctable. As a result, the 0% point, 50% point and 100% point are beforehand set according to the modes of the dots to be measured, after which the 50% point is adjusted independently, whereby the dot area rates are measured by making the errors between the light transmittance or light reflectivity and the dot area rates negligible.

PURPOSE: To eliminate a measurement error, by a method wherein, in case transmissivity and reflexbility, which are the data representing the density or the mesh area rate of the object to be measured, the weighting for a transmitting light and a reflection light on a measured surface is conducted. CONSTITUTION: A film sheet 19 is placed in the proximity of a light source 1, and lighting is conducted so that a light amount 1 at a central part of a measured surface is largest and the light amount at the point on the measured surface decreases as said point approaches the periphery of said object. A condenser lens 2 collects light emitted from the light source 1, and an uniform light amount distribution is obtained at the measured surface. A light, corresponding to transmissivity or reflexibility of the object to be measured, is sent to a light-receiving part. COPYRIGHT: (C)1981,JPO&Japio | ||||||

Square cells of a gravure plate each have three straight line-segments as printing elements. The width of the line-segments is varied to give the tone density required at that cell. Co-linear elements from different cells form broken lines of variable density stretching right across the page. With this form of rater. Moire effects are avoided when line segments of different colours run in slightly different directions. An angular separation of 1 deg. can be enough. In another form, a half-tone original is photographed through a screen consisting of a set of parallel lines (450-1000 per inch) at right angles to which the tone density varies sinusoidally, with a maximum at each of the parallel lines. | ||||||

An improved relief printing plate and method for producing said plate is disclosed. Substantially all sizes of relief features resolve a fixed pattern which improves print quality. The pattern is applied to image areas in halftone data used to produce an image mask that is subsequently used to convert a plate precursor into a relief plate. The accuracy, ink density and tonal response of printed images corresponding to relief features that include the pattern are comparable or better than relief features produced without the pattern. | ||||||

238 | Improved drawing of continuous tone image by reducing cluster formation of half-tone dot | JP29758698 | 1998-10-06 | JPH11221967A | 1999-08-17 | HORSTEN BART; DELABASTITA PAUL; BOSSCHAERTS JACOBUS; SCHELLEKENS LUC |
PROBLEM TO BE SOLVED: To realize a more excellent tone drawing by a method wherein when a continuous tone image including a stage wherein a screening is performed by a degree-modulation half-tone method, is drawn on a recording material, a negative crosstalk regarding adjacent exposed micro-dots is provided. SOLUTION: When a screened reproduction of a continuous tone image is performed by using an electronic screening modulation of a manuscript, for the half-tone image, the continuous tone or the gray level of the manuscript image are reproduced by changing the dimension of the half-tone dot, the number of the half-tone dot per unit area and/or the density of the half-tone dot. In this case, when micro-dots in the vicinity are exposed to an energy in order to change the optical density of the micro-dots, a negative crosstalk is set as a local micro-dot contraction effect which appears in the half-toning. By this method, a favorable tone-drawing is made possible, and the image quality is improved. | ||||||

In an electronic image reproduction system, a halftone dot film of a density distribution of a specific pattern is produced by obtaining a value l expressed by an equation l=f(x)+g(y) representative of the specific pattern corresponding to the density value. By superimposing a density signal corresponding to the value l on an image signal developed by scanning an original, a reproduction image of the original, modulated by the density signal of a specific pattern, is obtained. |
