Embodiment Construction

[0010] The technical contents of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0011] As shown in the attached picture, first select a color oil painting of "Water Wheel (1650-1652), Roysdal (1628 / 1629-1682)" and input it into the computer to convert the flat continuous tone picture into dot composition. After computer color separation processing, it is processed into a three-color halftone dot film through a film sending machine. Select a copper plate slightly larger than the color picture for sanding and degreasing, and then use screen printing technology to print on the copper plate to form a photosensitive coating film. Put the film and the copper plate together and use a high-pressure tribute lamp for photosensitive treatment, and then put the copper plate into an aqueous solution of sodium bicarbonate with a concentration of 4% by weight for developing treatment, which will make the "waterwheel (1...

Abstract

The invention relates to a kind produce method of colorful cooper board picture, there are fowling steps of the process: producing menu film, besmearing sensitive coat film on the cooper board, press film to cooper and make sensitive management, then developing, eroding, fading sensitive coat film, variegation, antisepsis, cutting, framing up and so on; its character is producing the menu to tricolor microdot film after computer dichroism process; printed circuit sensitive film on the cooper board by silk screen technology; electrochemistry electroanalysis eroding; dyeing the cooper board to white at first, then make tricolor color filling or colorful spray color filling. The colorful cooper board which is produced with this method, has high emulator degree, the color and line of the menu is hairlike, no brushwork imprint, very vivid. It is not special for art automobileeer man, others can also produce, easy operation, and can be volume-produced.

Description

technical field [0001] The invention relates to a method for corroding and duplicating a color picture on a copper plate. Background technique [0002] At present, the method of copying ink painting to metal plate has appeared, which solves the problems of bad preservation and mass copying of ink painting on paper. However, it is only possible to use manual methods to fill in thick lines on the simple tones of ink painting, and it is required that the coloring personnel must be art professionals to do so. Therefore, the color of the subtle pictures such as colorful oil paintings, traditional Chinese paintings, and photos cannot be drawn, and there are traces of strokes, which cannot reach the level of simulation. Contents of the invention [0003] In view of the above-mentioned problems, the purpose of the present invention is to copy colored pictures, such as colorful oil paintings, traditional Chinese paintings, photos, etc., onto copper plates to make colored copper pl...
