Embodiment Construction
[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0023] refer to Figure 1-4 Shown, a kind of anti-sleeving printing method is characterized in that, described method comprises the following steps:
[0024] S1) Divide the black-and-white document to be printed in black and white into two areas: a predetermined area 1 and a manual operation area 2; the predetermined area 1 is the visual part of all black characters on a white background, and the above-mentioned Manual operation area 2 is the relevant information, signature, and seal that need to be manually filled in after printing; image 3 As shown, the original printed file will be divided to obtain three predetermined areas 1 and one manual operation area 2;
[0025] S2) Perform inverse color processing on all printing areas except the manual operation area 2 to obtain a new printing file with black background and white charac...

The invention discloses a printing method capable of preventing overlay printing. The printing method comprises the following steps of: performing regional division on a file which is provided with black characters on a white background and is to be printed in black and white, thereby forming a set region and a manual operation region; then, performing inverse-color processing on all printing regions except from the manual operation region, thereby obtaining a novel printed file which is printed with black characters on the white background; and enabling a printer to print the printed file which is printed with black characters on the white background. The invention provides a convenient and quick method for preventing secondary printing of the file. The printing method improves authenticity and reliability of the file.
Description
technical field [0001] The invention relates to the field of printing methods, in particular to a printing method for preventing overprinting. Background technique [0002] Since the development of printing technology in the 20th century, it has already been popularized in people's daily work and life. Usually printing is black ink printing on a white background. Although this is convenient and fast, it also saves printing ink, but it also brings certain problems. For a contract or document that has been printed and filled in or stamped with an official seal, there is a possibility that the printing method of black characters on a white background can continue to be printed twice, which is commonly referred to as copy printing, that is, using the original printing typesetting Adding new printing content on the basis of existing documents, resulting in lower reliability of printed files, and it is difficult for people to distinguish whether to print twice. Contents of the ...
