# CMYK ICC CLUT試験資料
`icc-cmyk-lut.pdf`は、同じCMYK入力をICCベクター・ICC画像・DeviceCMYK対照で表示する生成資料である。自作ICC入力プロファイルのCLUT頂点と数式から色の期待値を定める。制作条件・数値・既知の差は[描画比較記録](../../../results/cmyk-lut/README.md)を参照する。
`manifest.json`はPDFとICCのSHA-256、16個のICC色測定点、8個の対照点、生成器hash、測定対象外の範囲を保持する。物理的な印刷条件やモニターを校正するためのプロファイルではない。PDFiumと期待色の差が見つかっており、正解画像の人による承認は未完了である。
