Abstract

PURPOSE:To make dot revolution with the same photoengraving machine, by installing an adapter provided with a contact screen for dot resolution and a condenser on the surface of the stage of the photoengraving machine. CONSTITUTION:A freely removable adapter 14 is installed on a stage glass 10 on which manuscripts are placed, and the adapter 14 is composed of a contact screen 15 for dot resolution, a condenser 16, such as Fresnel lenses, etc., a projecting lenses 17, a light source 18, etc. Moreover, it is arranged that the contact screen 15 is sufficiently fitted to the stage glass 10 and projected pictures are enlarged or contracted by moving the projecting lens 17 and the condenser 16 upward and downward. In this way, any special cameras used in conventional methods for dot resolution are eliminated, and the dot resolution of photograph is made by utilizing the photoengraving machine.
