彩通（Pantone）Smart布卡与标准数据的差异小于0.5DEcmc（2：1），同时也通过目视的一致性测试。
How is consistency of PANTONE SMART Swatch Cards maintained?
We have improved our own manufacturing processes by ensuring all spectral readings are performed in temperature and humidity conditioned environments, and our lab-to-production correlation is less than 0.5 DE CMC(2:1).
Every dye lot is evaluated against the master digital standard and must pass both the digital and visual evaluation to become a PANTONE SMART color swatch card.
FYI – Pantone conducts all visual and instrumental evaluations under D65 lighting in a temperature and humidity controlled environment. For optimum color viewing and color measurement, we recommend a temperature of 70° F (21° C) and 50% relative humidity.
