摘要： A moire simulator comprises a transparent flat plate bearing a pattern (M) composed of grating patterns having equal grating constants and equal grating shapes, the plate being provided with means (S), such as an angle scale, for the measurement of in-plane rotation of the plate. In use, the moire simulator is superposed on an original and rotated thereon to a rotation angle with respect to the original at which the extent of moire pattern generation is the lowest. The rotation angle is read off using the angle scale and used to calculate the screen setting angle with will minimize moire pattern generation in the subsequent screening process.

摘要： A coating applicator is provided having a plate cylinder including a cylindrical body about which a coating plate is mounted in sleeve-like fashion. The plate is the type used in the flexographic printing industry, and is made of photosensitive, monomeric material. The longitudinal edges of the plate are mounted to the cylindrical body using a clamping mechanism which permits easy installation and removal. Even with relatively light pressure, the photopolymer plate releases a substantial portion of the coating material when the plate is applied to a workpiece. Consequently, the composition and secondary rollers may be spaced apart by a gap slightly smaller than the thickness of the workpiece. Because of this gap, coating material does not tend to be applied from the plate cylinder to the secondary roller, thus reducing the safety and environmental problems associated with cleaning the secondary roller.
摘要翻译：提供一种涂料涂布器，其具有包括圆柱形主体的印版滚筒，其上以套筒状方式安装涂布板。该板是柔性版印刷工业中使用的类型，由光敏单体材料制成。板的纵向边缘使用夹紧机构安装到圆柱体上，该夹紧机构允许容易的安装和拆卸。即使在相对较轻的压力下，当将板施加到工件时，光聚合物板释放涂层材料的大部分。因此，组合物和次级辊可以间隔开一个略小于工件厚度的间隙。由于这种间隙，涂层材料不倾向于从印版滚筒施加到次辊，从而降低与清洁次辊相关的安全性和环境问题。

摘要： A method and apparatus for obtaining an accurate half-tone dot percent of each color separation where a color designated by a color specimen is to be reproduced by printing of ink of the colors, for example, yellow, magenta, cyan and black. A variety of color charts printed using predetermined combinations of half-tone dot percents are optically measured to obtain color information of the colors printed on the color charts. The obtained color information values together with the corresponding predetermined combinations of half-tone dot percents therefor are then utilized to prepare a conversion table of color information and corresponding half-tone dot percents for reproducing each of the colors printed on the color charts. A color specimen is then optically measured to detect color information of a color to be reproduced. The color information obtained from the color specimen is then successively compared with the color information of the conversion table, and the color information of the conversion table is selected which most closely corresponds to the color information obtained from the color specimen. The combination of half-tone dot percents corresponding to the selected color information from the conversion table is then displayed or otherwise outputted. The outputted combination of half-tone dot percents may then be used to reproduce the color designated by the color specimen. The method and apparatus also provides for interpolation operations if the color information obtained from the specimen does not precisely correspond to the color information in the conversion table. Further, the method and apparatus also provides for generating an expanded conversion table having expanded combinations of half-tone dot percents and corresponding expanded color information, and for performing an interpolation operation if a value of 0% and/or 100% is included in the combination of half-tone dot percents corresponding to the selected color information so as to obtain an interpolated combination of half-tone dot percents corresponding more closely to the color information obtained from the color specimen.

摘要： In printing with dots, a dot percentage is one of the important factors which determine the quality of a printed matter, and accordingly it is essential to control the dot percentage throughout the printing process from makeup to printing. In order to readily and quickly measure the dot percentage with high accuracy, a microscope section and a display section are formed as one unit, and a correction circuit for light transmittance is provided.

摘要： A method for preparation of the final film used for engraving a flat screen, belt screen or rotary screen for a printing machine. The final film is prepared from a photograph of the image to be reproduced and engraved by known techniques on a screen so as to provide a continuous repetitive pattern on the face of a pile fabric dyed in a continuous print dyeing process.Select areas of photographic images are montaged and put into a repeat pattern within a predetermined outline to establish the basic repeat. Four continuous tone color separations are made of the selected pattern to provide yellow, blue, red and black continuous tone negatives which represent the four colors of the original image. Each color separation is posterized and half toned to provide eight positive films. The films are selectively combined, blown up to the desired repeat size to provide a negative or positive which is used to prepare a flat bed screen or rotary screen for an otherwise conventional printing process.

摘要： High resolution microimages of continuous tone photographs must be prepared in halftone form to enable inexpensive duplication of the microimages by conventional graphic arts processes. The halftone pattern in such microimages must have a spatial frequency of not less than about 40 line pairs per millimeter in order to enable the projection of an acceptably detailed enlarged image. In the present invention, such halftone microimages are prepared using an ultra-high resolution gradient density screen having therein an image of an interference fringe field resulting from an exposure of a preform of the screen to two interferring mutually coherent beams of radiation.
