| 21 | Method for direct plate making | JP12620884 | 1984-06-18 | JPS614062A | 1986-01-09 | KANEDA EIJI; MIYASAKA EIJI; HIROSE IWAO; YAMASHITA KOUJI; KAWAI KENJI |
| PURPOSE:To perform direct plate making with high resolution in daylight by superposing a contact screen and a printing plate one over another in a light shield state, exposing a continuous tone part of an original where continuous tones and lines are present together in a contact state, and taking only the screen out of a light shield part in the light shield state and exposing a line part. CONSTITUTION:The original has a continuous tone image and a line image together and the contact screen 6 and printing plate 1 are mounted on the mount table 5 of a photosensitive planographic plate 1 one over another in daylight; and the plate is exposed to the continuous tone image in a vacuum contact state and only the contact screen 6 is drawn out of a light shield cover sheet 7 in the light shield state. Then, the plate is exposed to the line image. In another way, the printing plate 1 is exposed to the line image and the screen 6 is inserted into the light shield cover sheet 7 in the light shield state and stacked, the plate is exposed to the continuous tone image in the vacuum contact state, and then the plate making process of the printing plate 1 is carried out. Thus, direct plate making, specially, multicolor direct plate making is easy carried out in daylight through said operation and numbers of printed bodies which are faithful to the original and have high resolution are obtained. | ||||||

| PURPOSE:To form an offset plate capable of obtaining a duplicated print having high density on the dark part, and besides, smooth continuous gradation, by using a synthesized positive formed from 2 kinds of specified screen images. CONSTITUTION:(i) A photosensitive material 4a is exposed to light passed through or reflected with an original and coming through a minute line screen 3a having >= about 200 lines, and developed to form a negative screen image (primary image). (ii) On the other hand, a photosensitive material 4b is alike imagewise exposed through the ordinary screen 3b having <=200 lines, and developed to form a secondary negative screen image 5b. A photosensitive material 6 is doubly exposed successively through the obtained 2 negative images 5a and 5b, and developed to form a synthesized screen positive image 7, and it is printed to a plate material 8 to obtain an offset plate. | ||||||

| PURPOSE:To print a picture line having a clean edge, by forming a picture line part on the surface of a plate with grooves corresponding to thin lines of an original plus projections dotted to the grooves and then filling the ink into the picture line part to perform the printing of thin lines. CONSTITUTION:The plate surface is etched with a resist of the carbon tissue which is obtained by printing and developing the thin lines of a negative screen and an original. Thus the area of the plate surface which is corresponding to the black background part of the grid-shaped negative screen is etched in accordance with the thin line. The area corresponding to the transparent part is not etched to remain as it is. The thin line is formed with a grid-shaped groove 5 on the plate surface 4 to oppose to the original, and at the same time an area 6 enclosed by the grid is projected. Such projections 6 are dotted regularly into the groove of the thin line. | ||||||

| The use of frequency-modulated or stochastic screening for lightening wet or waterless offset printing surfaces is disclosed. Films and plates which are used in such printing processes and which typically generate lighter printing surfaces by means of stochastic (or frequency-modulated) screening, are also disclosed. | ||||||

A method for the direct production of printing plates in which exposure of an image on a photosensitive lithographic plate and plate processing are conducted in daylight. A printing plate (1) overlaid with a contact screen (6) which is secured to a screen frame is disposed on a rest (5) in an area where light is shielded by a light shielding cover sheet (7). 'This area is evacuated so as to bring the plate into close contact with the contact screen (6). A continuous tone image of an original bearing the continuous tone color image and a line image is exposed on the plate (1). The vacuum state of the area is released with the light shielded state being maintained, and the screen frame with the contact screen (6) is drawn out of the range. The line image is exposed on the plate which is adhered to the rest by evacuating the light shielded area, and thereafter the plate is fed to a plate processing section and is processed there. |

Method for the photographic production of a document by simultaneously photographically copying a continuous tone image and a graphic data pattern with one exposure source, characterized in that the reproduction of the continuous tone image proceeds by exposing it with light and projecting the thereby image-wise modulutated light through a screen dividing the light-image in dots of varying size onto a photographic material, and the reproduction of the graphic data proceeds simultaneously by exposing it with said light and projecting the thereby pattern-wise modulated light through a screen dividing the original halftone pattern in dots of substantially same size printing them within a dot percentage range of 50 to 99 %. |

| Method for the photographic production of a document by simultaneously photographically copying a continuous tone image and a graphic data pattern with a single common exposure source, characterized in that continuous tone image is exposed to said light source and the thereby image-wise modulated light image is projected through a screen dividing the light-image in dots of varying size onto one area of a photographic material, and the graphic data is simultaneously exposed to said light source and the thereby pattern-wise modulated light is projected through a screen dividing the original halftone pattern in dots of substantially same size printing them within a dot percentage range of 50 to 99%. | ||||||

| In a halftone printing system, halftone positive prints are made directly from gray scale photographic negatives by an enlarger apparatus which shines a beam of light through the negative and focuses an image of the negative on a sheet of high contrast photographic printing paper through a halftone screen. A secondary light source is provided to irradiate the printing paper to provide satisfactory halftone representation of the gray scale. The positive halftone prints are assembled with cold type from which a negative is made. From the negative, a printing plate is then made. | ||||||
