The color formulations for the ColorChecker SG and ColorChecker Classic (24 Patches) needed to be changed for regulatory and compliance reasons. This is true for all black and gray shades as well as the color shades. Charts editions, which are manufactured after November 2014 have been and will be produced with the new colorants used within our coating process.

The production date of a ColorChecker SG and a ColorChecker Classic chart (A4 or LTR) is printed on the back side. For more information click here.

As a consequence, the new chart editions require the use of new colorimetric reference data for the creation of an accurate color profile. The new data can be downloaded as CGATS formatted text files from the links below. Owners of charts produced prior to November 2014 should continue referring to the reference data ‘Before November 2014’. Owners of charts after November 2014 or newer should refer to the new reference data ‘After November 2014’.

由于监管合规需求，ColorChecker SG与ColorChecker Classic（24色块版）的色彩配方需进行调整，该调整涵盖所有黑色、灰色色块及彩色色块。2014年11月之后生产的色卡版本，均已采用且后续将持续使用本公司涂层工艺中的新型着色剂。

ColorChecker SG与ColorChecker Classic（A4或LTR规格）色卡的生产日期印制于色卡背面。更多信息请点击此处。

因此，新版色卡需使用全新的比色参考数据，方可生成精准的色彩配置文件。上述新数据可通过下方链接下载为CGATS格式的文本文件。2014年11月前生产的色卡持有者，应继续沿用"2014年11月前"版本的参考数据；2014年11月及之后生产的色卡持有者，则需使用"2014年11月后"版本的新参考数据。
