Abstract: This invention relates to a manufacturing method for a high-density copper plate memorial which comprises the following steps of: digitalizing the desired image for its storage in a computer file (S100); adjusting the image level by converting the stored image into halftone image (S102); printing the halftone image into a transparent film (S104); coating the surface of the foreign materials-free copper plate with a glue containing a hardening agent and photosensitizer, followed by its drying (S106); compressing the printed image film to the copper plate for its photosensitization (S108); heating the glue for appropriate etching (S110); etching the surface of copper plate using an impregnating agent to form about 1000˜1600 dots per cm2 (S112); coating the etched copper plate with a painting material to obtain the same image as the image printed on a film (S114); sanding the copper plate to obtain the desired surface roughness (S116); and, coating the copper plate with a protective film so as to protectiv
