Problems solved by technology

Add a certain amount and type of anti-counterfeiting fiber to the base paper to produce anti-counterfeiting fiber base paper, and then produce carbon-free paper with anti-counterfeiting function through special coating processing. Carbonless copy paper is used for printing barcode symbols, and the result of spray printing cannot reach the national standard A level of barcode reflection curve quality after testing.
[0004] Using the current carbonless copy paper to print barcode symbols with water-based ink, the water-based ink is easy to diffuse and penetrate deeply on the coating, forming ink line edge gaps, etc., so that the quality of the barcode reflection curve cannot reach the national standard A level

Abstract

The present invention relates to the technical field of carbonless papers, in particular to a coating formula for a jet-printed non-color-developing side of a carbonless paper used in the aqueous ink jet printing of bar code symbols. Calculated according to weight portions, the coating formula contains the following ingredients: 700 to 900 portions of water, 2 to 10 portions of dispersant, 50 to 70 portions of kaoline, 90 to 110 portions of calcium carbonate, 125 to 140 portions of laminating adhesive, 3 to 10 portions of polyvinylpyrrolidone, 3 to 5 portions of optical brightener and 2 to 5 portions of foam suppressor. When aqueous ink is used to jet-print the carbonless paper adopting the jet-printed non-color-developing side and coated with the coating formula to print bar code symbols, the problems of the diffusion and deep permeation of the aqueous ink on the coating of the carbonless paper and the nicks on the edges of ink lines can be effectively resolved, so that the quality of the reflection curve of a bar code can come up to the class A of the national standard.

Description

Technical field: [0001] The invention relates to the technical field of carbonless copy paper, in particular to a coating formula for spray printing a non-color-developing surface of carbonless copy paper for printing barcode symbols with water-based ink. Background technique: [0002] At present, carbonless copy paper is widely used in commercial forms such as banking, taxation, telecommunications, post and telecommunications, insurance, etc. for its advantages of easy use, clean hands, large number of copies, clear handwriting; convenient processing, neat overprinting; especially suitable for computer printing. Invoices, forms and documents for food, beverages, etc. With the expansion of the scope of use of carbon-free paper, part of it is used to print barcode symbols. At present, there are three types of barcode symbol printing: laser inkjet printing, ink printing, and water-based ink printing. Water-based ink printing is low in cost and environmentally friendly, but car...
