Abstract
The present invention relates to anti-counterfeiting ink which is composed of 40 to 60% of vegetable oil with light permeability, 10 to 30% of formaldehyde, 1 to 5% of cupric sulfate, 20 to 30% of ink mixing oil, 5 to 9% of blending agent prepared from etanol and shellac, and proper amount of pigment. The present invention can be printed on bar codes, trademarks and other characteristic patterns to form invisible bar code patterns which can not be seen by naked eyes, while the invisible bar code patterns covered by the ink can be detected by the existing optical detection devices. With the advantages of high security and anti-counterfeiting performance, the present invention is especially suitable for preparing low-quality invisible bar codes.
Description
The present invention relates to a kind of anti-forgery ink.
Existing anti-forgery ink mostly is an Antiforge fluorescent ink, as among Chinese patent bulletin CN1101365A disclosed " Antiforge fluorescent ink " and the CN117927A disclosed " fluorescent anti-fake mark and preparation method thereof ", constitute by in printing ink, adding fluorescent material, directly fluorescent ink is used to print make and shows one's color or recessive characteristic pattern uses as thing made of paper such as trade mark, Valued Securities, show the pattern characteristics content for identification by UV-irradiation.The shortcoming of this fluorescent ink is that its feature can manifest by UV-light and seen by the naked eye simply, is equally easily forged by imitated.Another deficiency of this fluorescent ink is to lack confidentiality and be not suitable for secret occasion.
The purpose of this invention is to provide the printing ink that another kind can play anti-fake effect, this printing ink can cover by printing on the feature such as bar code trade mark feature hidden and make it " stealth " and do not seen by naked eyes, and the feature that is hidden can be detected out again by pertinent instruments.
Realize the recessive anti-forgery ink of the object of the invention being constituted by the vegetables oil that possesses light transmission of 40～60% (weight percents), 10～30% white bole, 3～5% formaldehyde, 1～5% copper sulfate, 20～30% stand linseed oil and 5～9% with ethanol and the synthetic blending agents of shellac and an amount of pigment.The color of the feature that employed pigment can hide according to desire is selected for use, the printing ink that is made can be covered it after being coated on this feature fully and makes it become " stealth " content.Can utilize existing the inspection as optical detection apparatus such as laser gun, CCD scanning devices to show when needs are assert, the detection light beam of these optical detection apparatus all can see through this and cover printing ink and the content detection that it covered is come out.Thereby play stealth and maintain secrecy, prevent the purpose of copying.
Printing ink of the present invention can be fully hidden and do not seen by naked eyes and taken a picture, duplicate with feature, can detect by existing various optical detecting instruments again simultaneously, according to these characteristics, the Item Management occasion that can be used for various needs to be keep secret, as in bar code management system, printing ink of the present invention covered be imprinted on the original bar code, make original plain code change into invisible-bar-number, make it not influence the stealthy secret function that increased tool when detecting.
Be embodiments of the invention below:
Get concentration and be 98% ethanol modulation shellac and obtain cotton-shaped shellac blending agents, the optional Viscotrol C of vegetables oil, or other is as the vegetable seed wet goods, pigment is elected red pigments as, white bole is made finely powdered earlier, each composition weight percent is: Viscotrol C 50%, formaldehyde 4%, copper sulfate 3%, white bole 20%, stand linseed oil 20%, pigment 3% evenly promptly make concealed anti-false China ink of the present invention with previous cotton-shaped shellac blending agents blending of preparing.
