NチャンネルICCプロファイルは、標準のCMYKインクチャンネル以上を使用する印刷デバイスの色再現を処理するために、カラーマネジメントで使用されます。これらのプロファイルは、正確で広色域のカラー出力を実現するために不可欠です。色の忠実性が最も重要な商業印刷やパッケージング印刷では、特に価値があります。

SpectraProofは、FOGRA55 CMYKOGV ECGのようなあらゆるNチャンネルICCプロファイルをソフトプルーフし、ソフトプルーフモニターに正確に色を表示できます。すべてのチャンネルをジョブ検証で検証できます。

ECG印刷では、希望する色を正確に再現するために、適切なカラーマネージメントとキャリブレーションが重要です。特に、この比較的新しい印刷コンセプトでは、SpectraProofを使用した正確なソフトプルーフにより、ソフトプルーフおよび印刷において、迅速、正確、かつ色鮮やかな結果を得るための多くの時間と労力を節約することができます。

What is Extended Color Gamut (ECG)

Extended Color Gamut (ECG) printing is a printing technology and technique that expands the range of colors that can be reproduced in the printing process beyond what is possible with the traditional four-color process, also known as CMYK (Cyan, Magenta, Yellow, and Key/Black). ECG printing typically uses additional ink colors to expand the color gamut and improve the color accuracy of printed materials.

Key points about ECG Extended Color Gamut printing

  • Extended color gamut: ECG printing uses a wider range of ink colors beyond the standard CMYK inks. These additional inks in standards such as FOGRA55 CMYKOGV include orange, violet, and green. They may also include other spot colors, special inks, or custom blended inks.
  • In SpectraProof Standard, you can use Orange, Violet and Green with N-Channel ECG color profiles like FOGRA55. If you use different colors in printing, switch to SpectraProof Professional. Here, you can use, measure, and apply any color to the additional color channels.
  • Improved color accuracy: By using a wider range of ink colors, ECG printing can achieve more accurate and vibrant color reproduction, enabling better brand color matching and delivering high-quality, photo-realistic images.
  • Better Reproduction of Brand Colors: ECG is especially valuable for brand owners and designers who want to maintain precise control over the colors in their branding and marketing materials.
  • Improved print quality: ECG printing often results in higher levels of detail, smoother gradients and a wider color gamut. This can be especially beneficial for applications such as packaging, labels and promotional materials.
  • Reduced spot color usage: ECG printing expands the color gamut. It can also reduce the need to use a large number of separate spot colors. This can be costly and complex to manage.
  • CMYK as a base color: CMYK colors are often used as a base in ECG printing, with the additional inks applied as needed to expand the color gamut.
  • Extended Color Gamut printing is widely used in the packaging industry, where vibrant and consistent colors are essential for branding and marketing. It is also used in various other areas of commercial printing and production where color accuracy and quality are paramount. By expanding the color gamut, ECG printing offers greater flexibility and precision in color reproduction. It helps meet the demanding color requirements of today’s print projects.
