Zusammenfassung:	PURPOSE:To constitute sharply a printing plate having >=2 steps which are different in depth by coating a photosensitive resin sol to a screen mesh, printing the 1st stage of a design thereto, subjecting the sol to the 2nd stage of coating and printing and developing the entire part. CONSTITUTION:The photosensitive resin film is coated on the mesh 1 and the design 3 is superposed thereon and is subjected to the 1st time of printing. The marking edges 8 for registration of the image 3 and the image 4 are preliminarily developed. The entire plate surface is wiped with a soft fabric-like material such as chamois leather moistened with water in order to active the surface and thereafter the 2nd layer of the photosensitive resin sol is coated over the entire surface and the drawing of the image 4 is registered by means of the marks 8, then the films are superposed and are subjected to the 2nd printing. The plate having the steps is sharply obtd. if the entire part is developed.
