真っ黒については手動で平網を作るならC0M0Y0K100で真っ黒になりますが下地は透けて見えてしまいます。
C40M40Y40K100のようにCMYを追加したリッチブラックと呼ばれる状態にすると下地は透けません。推奨されるリッチブラックのCMYの量は印刷会社によって多少異なります。
元のRGBの色にできるだけ近いCMYK値を示したものであり、1〜2％など中途半端なCMYK値もありますが、実際のCMYKデータの作成作業で平網を作るならたいていは中途半端なCMYK値にせずある程度キリの良い数字にするでしょう。
このページにおけるRGBの色のCMYKへの変換の仕方
同じRGB値でも表示する色空間が異なれば色は異なります。
また、CMYKに変換すると言っても、変換先のCMYKプロファイルによって色は異なります。
このページではHTMLで使用するカラーネームの各色をsRGB色空間で表示した時の色をJapanColor2001CoatedのCMYK値に変換してみます。
RGBの色をCMYKに変換するにあたり、CMYKの色域外の色もあります。できるだけ元の色に近い変換結果になる変換方式でプロファイル変換した場合の色を表示しています。
なお、プロファイル変換は変換方式によて結果が異なり、また端数の処理やその他の理由で誤差もあるので、このページの表はあくまで一例です。
