Embodiment 1

[0031] Input the rubbing image of Wu Daozi's "Portrait of the First Teacher Confucius Xingjiao" in the Tang Dynasty into the computer with a scanner. And use Photoshop to make appropriate adjustments to the picture. Then enter Confucius' "The Analects" into the computer through the keyboard, and the number of words including punctuation marks and spaces is about 24,000. Then use CorelDRAW to arrange the text and pictures, the statue of Confucius is in the center, and the whole "Analects of Confucius" surrounds it. Typesetting the final graphic into a square shape, the target size of the final product graphic is 2.5 cm x 2.5 cm, and reducing the graphic of the data file to a size of 2.5 cm x 2.5 cm. Use the film output device to enlarge the length and width of the figure by 10 times and output the film, and use the attachedfigure 1 The process flow shown uses the optical micro-imaging technology to first reduce the length and width of the film sheet by about 10 to make a shrin...

Embodiment 2

[0034] Input the photocopy of Tang Dynasty Feng Chengsu's calligraphy handwriting copying Wang Xizhi's "Lanting Preface" into the computer through the scanner. The original calligraphy manuscript is 24.5 cm high and 69.9 cm wide. The full text has a total of 28 lines and 324 characters. Adjust and properly process the outline of the font, and remove the original seal above, and edit the scanned images of the seal carving seals of Shanghai Tianzuo Electronic Technology Co., Ltd. and Wu Qiangzhi Seal in the above calligraphy image as special marks. Copy the above image into five columns and ten rows for a total of 50 repeating units on the same file. Output the content of the image file in an area of ​​50 cm x 50 cm on the film output device. Then use optical micro-imaging technology to reduce the length and width of the film sheet by about 10 to make a primary dry plate, and use the obtained primary shrink dry plate directly as a photolithography mask.

Abstract

The invention discloses a making method of micro characters and pictures. The making method is characterized by comprising the following steps: firstly inputting characters and pictures into a computer and preparing a film, preparing a photographic plate motherboard through using an optical microimaging and step repeating technology, engraving the photographic plate motherboard to a chromium plate motherboard through using a modern micro-photoetching technique, and copying the micro characters and pictures on a target file in batches through using methods of photoetching and corroding, photoetching and stripping, photoetching and electroforming, and electroforming and mould pressing by utilizing the motherboard. The making method disclosed by the invention is high in making efficiency, short in technique procedure and small in equipment investment. By adopting the making method disclosed by the invention, the heights of the characters can be shortened to be smaller than 150 microns, more than 44 characters can be arranged on an area of 1 square millimeter, and the micro proportion for the characters is suitable for enjoyment and identification. A made product of the micro characters and pictures can well keep the original style and characteristic, so that the making method can be not only used for making a piece of high-end artware, but also used for encrypting and anti-counterfeiting of common goods.

Description

Technical field: [0001] The invention relates to a method for producing microtext pictures, in particular to a method for producing microtext pictures by using a microlithography process. Background technique: [0002] Micro-carving and micro-engraving are the predecessors of today's miniature text and pictures. As an ancient traditional craft, it originated in China and has a history of thousands of years. In the course of development from the beginning to the present, micro-carving and micro-carving are mostly made by hand, which requires extremely high skills from the creators. [0003] In the existing literature, there is "microtext pattern mold making method" application number 01111132.1, which does not disclose the preparation method of the miniature text pattern stereotype therein. Existing literature "method for making miniature Chinese characters using microlithography technology" application number 200510011686.5 and "microtext array anti-counterfeiting mark and...
