Recently, a lot of lottery people have reported that some instant lottery tickets are difficult to distinguish between authenticity and even "loopholes". You can use the needle to scrape or invoicing, and you can know if you win. For this issue, this reporter introduced lottery printing process features for Lottery and mastered the techniques of identifying the authenticity of billing.
Process dark anti-counterfeiting prevention
The issuance and approval procedures for the issuance of welfare lottery in China are very strict. They are highly authoritative, and their circulation, face value, specifications, etc. will not be arbitrarily changed once they are confirmed, nor will they be revised or reprinted. In order to prevent the buyer from forging a winning ticket, the lottery ticket generally needs to go through dozens or even dozens of processes before it can be printed.
The most valuable of these is the implementation of the “process dark law†in the production of lottery tickets to ensure that no one (including printing manufacturers, ticket buyers, and China Lottery Distribution Center) can know the lottery tickets printed by the winning lottery ticket. The distribution situation prevented the picking of votes.
Anti-counterfeiting is to stop counterfeiters from forging fake winning tickets. The purpose of the anti-picking is to ensure that each ticket purchaser has equal chances of winning. Even if a real-looking lottery ticket with genuine appearance appears, it can be identified quickly and easily.
Printing paper and ink have strict requirements
Instant lottery tickets are one-off, so with paper printing, 150-200g/rated coated paper is generally used. First of all, with offset printing of text, numbers, images, etc., the printing surface of the offset printing is flat, which is advantageous for the final screen printing. The offset-printed printing surface must be coated with a good transparency, and its function is not only to make the masking ink strippable, but also to make the offset printing image stable. The final screen printing is then performed on the coating using masking ink, typically only partially masked thick film printing is performed on the letter and the digits.
After the shading ink with stability is printed on the lottery ticket, it should be easier to peel off with nails or coins. The ink lottery ticket printed as a commodity shall remain stable for at least one year; after the masking ink is stripped, the exposed characters, numbers, etc. cannot be contaminated by the ink; the masking ink must have sufficient masking; the ink that conceals the ink The film must have certain toughness, that is, in the lottery ticket drying, cutting and other operations, the ink film surface can not be damaged due to some kind of external force, as the commodity in circulation also have the same requirements.
Lottery tickets are printed by designated manufacturers
According to insiders, in the past years, the printing of lottery tickets, like the printing of banknotes, has quite strict rules and regulations in production management, and has extremely high quality requirements in terms of plate making and anti-counterfeiting.
The lottery printing companies generally print the designated printing products for special securities, and part of the lottery labels the name and code of the printing manufacturer.
