An ICC profile describes the color characteristics of a device, ink-substrate combination or color space. It helps software convert colors so that the intended appearance can be reproduced more consistently.
答案 CN：
ICC Profile 用于描述设备、墨水—材料组合或色彩空间的颜色特性，帮助软件进行颜色转换，从而更稳定地还原目标颜色。
Question EN: Why does every substrate need different color profiling?
问题 CN： 为什么不同材料通常需要不同色彩 Profile？
Answer EN:
Different substrates absorb, scatter and reflect ink differently. These physical differences change achievable density and color gamut, so one profile may not accurately represent every substrate.

A lower ΔE generally indicates closer color matching, but acceptable limits depend on the application, color, viewing conditions and customer requirements.
答案 CN：
通常更低的 ΔE 代表颜色更接近目标，但可接受标准取决于具体应用、颜色、观察条件和客户要求。
Question EN: Why can the same color look different on different substrates?
问题 CN： 为什么同一个颜色在不同材料上看起来不同？
Answer EN:
Substrate whiteness, gloss, texture, absorption and reflectivity influence the perceived result. Color management must therefore be built around the actual production substrate.
答案 CN：
