摘要： PURPOSE:To easily prepare a film having transmitting pictures by adhering reflected originals to a supporting material with high reflecting density at specified trimming and layout, setting up the adhered material on a scanner and exposing the reflected originals on a photosensitive film by prescribed scanning. CONSTITUTION:Reflected originals A-D consisting of positive pictures are adhered to the supporting material 8 having higher reflecting density than the max. reflecting density of these originals at the specified trimming and layout. The supporting material 8 is set up on the scanner so that when the reproducing curve l for the scanner is a density S3 higher than the max. reflecting density S1 and lower than the reflecting density S2 of the supprting material 8, all values are set to a previously determined dot percent P, and scanned to expose the reflecting originals A-D on a photosensitive film. Consequently the film having transmitting pictures can be easily obtained.

摘要： PURPOSE:To obtain smooth prints having sufficient density by using a screen, where the number of white lines in one direction is larger than that in the other direction and the area rate of a blackened part is >=56% and the width of white lines is uniform, as a screen for gravure. CONSTITUTION:The width of lateral white lines 8 is 15mu, and the width of longitudinal white lines 17 is 15mu also. A line ratio (a:b) of white to black with respect to longitudinal white lines 7 is (1:1.5), and a line ratio c:d of that with respect to lateral white lines is (1:1.5). With respect to the number of lines, 677 longitudinal white lines are provided per inch, and 106 lateral white lines are provided per inch, and the area rate of the blackened part is about 56%. On the surface of the plate for gravure printing produced in this manner, the pitch of longitudinal banks due to screen printing for gravure is reduced very much and the moire pattern generated between these banks and a halftone positive is inconspicuous, and the pitch of lateral banks is increased very much and the moire pattern between them and the halftone positive is difficult to generate.
摘要翻译：目的：通过使用屏幕获得具有足够密度的平滑印刷品，其中一个方向上的白线数量大于另一个方向上的白线数量，并且黑化部分的面积率> = 56％，白线宽度是均匀的，作为凹版的屏幕。构成：横向白线8的宽度为15mu，纵向白线17的宽度也为15mu。相对于纵向白线7的白色与黑色的线比（a：b）为（1：1.5），相对于侧面白线的线比c：d为（1：1.5）。对于线数，每英寸提供677根纵向白线，每英寸提供106条横向白线，黑化部分的面积率约为56％。在以这种方式生产的用于凹版印刷的板的表面上，由于用于凹版印刷的丝网印刷而产生的纵向间距的间距变得非常大，并且在这些银行和半色调正面之间产生的波纹图案不显眼，并且侧向横列的间距增加了很多，它们之间的莫尔图形和半色调正面很难产生。

摘要： PURPOSE:To reduce rough feel and to make a moire pattern inconspicuous, by dividing the opaque parts of parallel square lines by parallel transparent lines perpendicular or diagonal to the parallel square lines. CONSTITUTION:Transparent parts 11, 21, 31, 41 and opaque parts 12, 22, 32, 42 form parallel square lines which are disposed alternately. Patterns 10, 20, 30, 40 of respective parallel lines are formed with the parts 11 and 12, 21 and 22, 31 and 32, 41 and 42, and the respective ratios are constant. The parts 11, 21, 31, 41 differ in line width, and the difference corresponds to the state that plural kinds of parallel line patterns having a specified line ratio and different line widths are selected irregularly and are arranged in parallel. The part 12 is divided by parallel transparent lines 11a and forms a cell 12a. Similarly, the parts 22, 32, 42 form the cells 22a, 32a, 42a divided by the respective parallel transparent lines 21a, 31a, 41a. The parallel transparent lines may be diagonal to the parallel square lines.

摘要： PURPOSE:To obtain a printing plate having excellent print resisting power, etc. by forming a resist layer on the surface of a gravure printing plate material made of a metal then scanning and exposing laser light so as to change the size of dots according to the density of an original image, removing the resist in the dot parts and etching the metallic material. CONSTITUTION:A resist layer 2 is formed on the surface of a gravure printing plate material 1 made of a metal such as copper. The layer 2 is then exposed by laser light while said layer is scanned by the laser light to change the size of dot parts 3 according to the density of the original image by which the layer 2 is evaporated away. The photosensitive resist layer 2 may be otherwise used so that the resin of the dot parts 3 is removed by a developing process. The material 1 is thereafter etched by an etching liquid such as an aq. FeCl3 soln. or the like and the residual resist 2 is removed. The original plate formed with gravure cells 4 is thus obtd. Since inspection and correction are possible in the stage of forming the parts 3 to the layer 2, the printing plate which permits a decrease in remaking of the original plate and has excellent printing resistance is obtd.

摘要： PURPOSE:To decrease generation of moire and to enable regeneration of a sharp image without affecting the angle of a halftone original and without deviating focus by forming an aperture of a scanning input device into a circular shape having a prescribed size. CONSTITUTION:An aperture 5 of an optical system which scans a halftone original 3 has a circular shape of such a size at which the circular picture element having the same area as the area of a square having the side corresponding to a screen pitch A can be inputted to a photoelectric tube 7. The difference in the rates at which picture elements 40, 41 having the centers of picture elements coinciding respectively with the centers of a black part 10 and a white part 11 occupy the respective black parts is small and the generation of moire is decreased without affecting the screen angle of the original. The reproduction of a sharp image is thus made possible without affecting the angle of the halftone original and without deviating the focus.

摘要： PURPOSE:To improve the area rate of blackened parts and to reproduce boundary parts between picture parts and nonpicture parts smoothly by making white lines in one direction different in width from white lines in the other direction on a screen for photogravure. CONSTITUTION:The width of segments 8 of a segment pattern in one direction is made narrower than that of segments 7 in the other direction on the screen for photogravure. When a photogravure printing plate is made by using the screen, parts corresponding to thick white lines 7 of the screen for photogravure are banks 9 and parts corresponding to thin white lines 8 are left as projecting parts 10 only at intersection parts of the banks 9 while the other parts are eliminated by side etching. Therefore, when screen lines nearly as many as usual are secured, the area rate of blackened parts is increased and when the area rate of blackened parts nearly as great as usual is secured, the number of screen lines is increased. Further, boundary parts between picture parts and nonpicture parts are reproduced smoothly.
摘要翻译：目的：为了提高黑色部分的面积率，并通过在一个方向上使白色线条沿着另一方向的白线在宽度上平滑地再现图像部件和非图像部件之间的边界部分，用于照相凹版的屏幕上。构成：在一个方向上的片段图案的片段8的宽度比在画面上的另一方向上的片段7的宽度窄得多，用于照相凹版。当通过使用屏幕制造照相凹版印刷版时，对应于用于照相凹版印刷的屏幕的粗白线7的部分是堤9，并且对应于细白线8的部分仅在堤9的交叉部分处留作为突出部10，而其他部分通过侧面蚀刻消除。因此，当屏幕线几乎保持一致时，黑化部分的面积率增加，并且当黑色部分的面积率几乎与通常一样大时，屏幕线数量增加。此外，平滑地再现图像部分和非图像部分之间的边界部分。
