Document record paper and printing method

Abstract

The invention provides a multilayer formed document record paper suitable for thermal printing heads and a printing method thereof. The multilayer formed document record paper is characterized in that: a part of a multilayer formed area on an upper layer is provided with a concave part; a leftover area is taken a first group thermal sensitive layer for printing of a thermal printing head; a lower layer multilayer formed area corresponding to the concave part on the upper layer is taken as a second group thermal sensitive layer for printing of the thermal printing head. According to the printing method, the part of the multilayer formed area on the upper layer document record paper which is provided with a thermal sensitive layer is provided with the concave part, the thermal printing head is used for printing in the leftover area; and then the thermal printing head is used for printing of the lower layer multilayer formed area of the lower layer document record paper corresponding to the concave part on the upper layer; so that excellent printing can be realized even if the number of overlapped paper of the layers is increased. The multilayer formed document record paper is novel in structure, high in working efficiency, and excellent in printing effects, and is convenient for operation.

Description

technical field [0001] The invention relates to the technical field of heat-sensitive printheads, in particular to a multi-layer receipt recording paper suitable for thermal printheads and a printing method thereof. Background technique [0002] As we all know, the current receipts and information are generally printed by printers, and the receipts are divided into triple sheets, quadruple sheets, etc. These sheets are composed of three layers (sheets) or four layers (sheets) of recording paper. Some The surface of each layer of recording paper is provided with a heat-sensitive chromogenic layer, or the surface of each layer of recording paper is provided with a color-developing layer formed by a developer, and a copy layer coated with a colorless dye on the back. This form of document recording paper The copying performance will be reduced, and the printing of the lower-layer document recording paper is often unclear and distorted during use, especially in the current banki...

Problems solved by technology

[0002] As we all know, the current receipts and information are generally printed by printers, and the receipts are divided into triple sheets, quadruple sheets, etc. These sheets are composed of three layers (sheets) or four layers (sheets) of recording paper. Some The surface of each layer of recording paper is provided with a heat-sensitive chromogenic layer, or the surface of each layer of recording paper is provided with a color-developing layer formed by a developer, and a copy layer coated with a colorless dye on the back. This form of document recording paper The copying performance will be reduced, and the printing of the lower-layer document recording paper is often unclear and distorted during use, especially in the current banking, securities, archives and other industries that require printing of six-page or eight-page documents, and the upper-layer documents The printing effect of the recording paper and the printing effect of the lower-layer receipt recording paper will have the problem of similarity limitation
