1 Scope

This procedure applies to non-fluorescent reflective standard swatches and transmissive standard swatches for colorimetric measurement (hereinafter collectively referred to as standard colors) First verification, subsequent verification and in-use inspection of the board).

2 Overview

Standard swatches are measuring instruments used to measure color. Standard swatches can be used to calibrate color measurement instruments, or as a target The criteria for judging color samples. Standard swatches can be made from different materials depending on the application. Reflective standard swatches using barium sulphate, oxygen Powdered with magnesium or polytetrafluoroethylene (PTFE); or made of ceramic, enamel, opal glass, etc. Special reflective standard swatches can be made from fabric, cardboard, plastic, etc. Transmission standard swatches are generally made of tinted glass or Made of materials such as plastic with uniform color and good transparency. 2.1 Principle of verification The chromaticity value of a standard swatch, the spectral inverse (radiation) ratio of its surface, the spectral power distribution of a standard illuminant, and The standard chroma observer is determined by spectral tristimulus values. The spectral reflectance of the reflective standard swatch must be in absolute spectral reflectance, ie, the reflectance is equal to 1, and the luminance is divided. The ideal fully reflective diffuser of the cloth independent of direction is the reflectance standard. The spectral transmittance of the transmission standard swatch is based on the air layer equal to the thickness of the sample being tested as the transmittance standard. 2.2 chromaticity calculation formula 2.2.1 The tristimulus values of the standard swatches X, Y, Z are calculated according to equation (1). X=K∑ Y=K∑ Z=K∑ Ïï Λλ (1) Where. λ---wavelength. The chromaticity calculation wavelength range is 380~780nm; S(λ)---the relative spectral power distribution of the CIE standard illuminant; It Φ(λ)---the spectral reflectance of the reflective standard swatch [represented by ρ(λ)] or the transmission mark The spectral transmittance of the quasi-color plate [represented by τ(λ)]; Δλ---wavelength interval. For primary standard swatches, standards with strong spectral selectivity Swatches or standard swatches with special requirements, usually 5nm; for secondary Standard swatch or standard swatch with less spectral selectivity, usually 10 nm; ...
