Embodiment 1

[0037] The six-part carbonless copy paper used as a bill, the method for detecting the qualification of the CB side and the CF side of the carbonless copy paper in production, and using the reference paper to detect the color development of the CB side and the CF side of the carbonless copy paper, comprises the following steps:

[0038] The first step: the preparation of reference paper,

[0039] A, preparation benchmark CB paper: with 400 parts of water, 40 parts of wheat starch spacers, 5 parts of tapioca adhesives, 120 parts of pressure-sensitive melamine formaldehyde resin microcapsules with a solid content of 40%, fatty alcohol polyether defoamer 1 Parts are mixed evenly to make CB paint, and the CB paint is coated at 40g / m 2 On the front side of base paper, the coating weight is 5g / m 2 , cut the coated CB paper into A4 size to make benchmark CB paper;

[0040] B. Preparation of benchmark CF paper: 400 parts of water, 3 parts of sodium pyrophosphate dispersant, 100 part...

Abstract

The invention relates to the technical field of NCR (no carbon required)-paper, and in particular to a method of using reference paper for testing chromogenesis on the CB surface and the CF surface of the NCR-paper. The method comprises the following steps: reference CB paper and reference CF paper are prepared; a pattern is edited and printed; collating is tested; and chromogenesis is tested and determined. The method is characterized by simple procedure and easy operation. Moreover, the method adopts the fixed reference CB paper and the fixed reference CF paper instead of CB paper and CF paper in production. Compared with the prior approach of taking random samples in the production field for combined inspection, the method eliminates the instability of test paper, and ensures that the real chromogenic capacity of the test paper can be determined and the test result is reliable. According to the result of the chromogenesis test, the fine quality fluctuation can be identified in time, the applied quantity is precisely controlled to avoid insufficiency or surplus, and other factors that affect the test are eliminated, thereby ensuring product quality, reducing manufacturing cost and effectively guiding production.

Description

Technical field: [0001] The invention relates to the technical field of carbonless copy paper, in particular to a method for detecting the color development of CB and CF faces of carbonless copy paper with reference paper. Background technique: [0002] Carbonless copy paper is generally composed of three paper sheets, namely upper paper (CB paper), middle paper (CFB paper) and lower paper (CF paper). The upper paper of carbonless copy paper (CCP) is also called Back-coated paper (CB, Coated Back), the back of the paper is coated with microcapsules containing Limin pigment oil, called CB coating; medium paper is also called front and back double-coated paper (CFB, Coated Front and Back), the front of the paper is coated There is a color developer, and the back is coated with microcapsules containing Limin pigment oil; the lower paper is also called surface-coated paper (CF, Coated Front), and the paper surface is only coated with a color developer, which is called CF coating...
