PURPOSE:To execute printing by abstracting a picture pattern or changing it to a special expression, by executing the photographing by a camera by shifting a focus a little, and executing a net photographing of a picture pattern original by using a net screen consisting of a character, a graphic or a symbol. CONSTITUTION:First of all, an original (a) on which a specified character, for instance, a collection of 'ABC' has been drawn by phototype setting is prepared, the collection of the character 'ABC' drawn on this original (a) is photographed by a camera by shifting a focus a little, and a net screen (b) is prepared. The net screen (b) obtained by this method is formed by the collection of the character 'ABC', and also as for a streak of each character, its density becomes low as it goes away from the center O of the streak. Subsequently, the net screen (b) and a picture pattern original (c) are superposed and photographed by a photoengraving camera, and a net edition (d) of the picture pattern original (c) is prepared. In the net edition (d) prepared in this way, the streak of the character 'ABC' is thick in the part where the density of the picture pattern original (c) is high, and the streak of the character 'ABC' becomes thin as the density of the picture pattern original (c) becomes low. |
