摘要： PURPOSE:To stabilize the reproducibility of a dot image by exposing a photosensitive material via two sheets of lenticular lens sheets which are disposed in intersection then developing the material. CONSTITUTION:Image light 1 is exposed, via lenticular lens sheets 2 and 3 which are disposed to intersect orthogonally with each other, on the surface of a photosensitive material 4. The transmitted light obtd. by illuminating an original or the light reflected therefrom may be used as the image light and the image light of a CRT is also usable. The light may be condensed, magnified or reduced by using other lenses according to need. A photosensitive body for electrophotography is also usable as it has less loss in quantity of light in addition to a silver salt photosensitive body which is usually used as the photosensitive material. A dot image is formed by the simple method without using any contact screen in the above-mentioned way and further the number of lines is changeable as desired by adding an optical system, whereby the loss in the quantity of light is decreased.

摘要： PURPOSE:To prevent moire and avoid roughness and unevenness by irregularly changing the shape and size of the transparent parts of a glass screen for halftone photography consisting of transparent and opaque parts. CONSTITUTION:An opaque part consisting of many irregularly bent segments 3 of lines and polygonal transparent parts 4 enclosed by segments 3 are formed on a glass substrate so that the area of parts 4 is adjusted to 16-25% of the total area. Since parts 4 are different from each other in area and shape, moire is not caused even if a plurality of such glass substrates are superposed in multicolor printing. In addition, parts 4 are specified in size and shape, so a glass screen having sufficient tone reproducibility and causing no roughness and unevenness to an image is obtd.

摘要： PURPOSE:To produce the captioned film capable of mass-producing relief printed matter easily and at low cost, by setting a relief pattern plain paper to the original frame of the camera for photographing the reflecting original, properly radiating light beams, and photographing into the lith-film by using straight line contact screen. CONSTITUTION:A glare-free, relief pattern plain paper 1 is set, as the object, in an original frame 2 of a camera for photographic reflecting original. At the opposite position of this plain paper 1 is disposed a camera lens 3, and the light beam from an illuminating body 4 provided on one side of the front side of the plain paper 1 is radiated so that the relief may be formed in desired state as seen from the central part of the lens 3. In this case, opposedly to the illuminating body 4 is provided an illuminating apparatus 5 consisting of reflecting plate M and auxiliary lamp N, and a weak light is radiated from the opposite side. After setting the angle and intensity of the illumination, a photograph is printed on a lith-film 7 by using a straight line (or dot) contact screen 6, so that straight line (or dot) relief negative film may be produced.

摘要： PURPOSE: To reduce or remove color-shifting at the time of masking and to attain masking with high-degree reproducibility by selectively applying coating to a surface zone or changing the structure of the surface zone, in processing. CONSTITUTION: In a control unit 20, a mask calculated for the frame of the top end of a film is prepared on an endless belt 21 by a forming apparatus 16. This forming apparatus 16 can generate the mask in such a manner that the surface structure of the belt 21 is selectively changed. For this purpose, the surface of the belt 21 can be roughened to reduce the light transmissivity of the selected part by increased light diffusivity, in the selected part. The forming apparatus 16 can function to form the mask, in such a manner that the coating is selectively applied to the surface of the belt 21, as well. At this time, the forming apparatus 16 includes a source for a coating material.

摘要： PURPOSE:To always record a distinct picture having high gradation on a sensitive recording medium by moving and arranging a plex screen arranged in an optical path to a working position or a non-working position. CONSTITUTION:The plex screen 12 is supported with a guide rod 15 and screw rod 16 through supporting members 14 at both sides movably and moved with the rotation of the screw rod 16 based on the rotation of a stepping motor 17. The stepping motor 17 is driven to be controlled by connected to a switching switch SW1 of the upper surface of a device main body 1 through a CPU 20 as a control means and the plex screen 12 is arranged to the working position near to the photosensitive pressure sensitive recording paper 2 in the case of switching the switch SW1 to a continuous gradation side. In the case of switching the switch SW1 to a plex gradation side, the plex screen 12 is moved and arranged in the non-working position apart from the photosensitive pressure sensitive recording paper 2 where the effect is lost. Thus, the distinct picture having high gradation can be always obtained according to the kind of original.
