ABSTRACT:
The present invention relates to a letterpress for transferring on which a dot-like fine form plate surface is formed closely resembling a photoimage, and to a method of transferring by use of the letterpress for transferring. The letterpress is formed by exposing a photosensitive resin through a photofilm to a parallel light to harden the film of the photosensitive resin corresponding to the lightscreening area of the photofilm. The area of the photo resin other than the hardened film is then removed by rinsing with water to form the letterpress which has a convex corresponding to the light-penetrating area of the photofilm. The convex is then directly coated with various dyes and press printed on and transferred to a transfer material, or the convex is coated with a photosensitive resin and press printed on a transfer material. The photosensitive resin film transferred is then exposed to light and a non-light exposure area is rinsed with water, thereby allowing the material to be applied as a resistant mask for dyeing or blast processing.
