CMYK イメージをロードし、meke_spotcolor により特別な色「All」を作ることによって CMYK 文書を作成します。いくつかのクロップマークを標準的なベクターグラフィックで描き、実際のページの外(クロップボックスの外など)にいくつかの情報テキストを出力します。
Acrobat 7 や 8 でテストします。メディアボックスが、文書、クロップページ、0 に設定されて表示されます。拡張、印刷処理、印刷プレビューを選択することで、「All」カラーにより全ての内容が分離プレビューの全ての組み合わせて表示されます。
/*
* Color space for crop marks:
* Create crop marks which will be visible on all color separations, using the
* special color "All".
*
* Create a CMYK document by loading a CMYK image and create the special
* color "All". Draw some crop marks with standard vector graphics and
* output some info text outside of the actual page area (i.e. outside
* of the CropBox).
*
* Test in Acrobat X/XI:
* Show the MediaBox with Tools, Print Production, More Production,
* Set Page Boxes, Set to Zero.
* Choose Tools, Print Production, Output Preview:
* All elements with color "All" will be visible in all combinations of
* separation previews.
*
* Required software: PDFlib/PDFlib+PDI/PPS 9
* Required data: CMYK image
