Grayscale rendering intent
The Grayscale rendering intent option specifies a rendering intent for color conversion. This conversion can be optimized for the type of gray objects being printed.
To control the appearance of text, graphics, and images in grayscale, select the appropriate rendering intent. The Fiery server allows you to select from the four rendering intents currently found in industry-standard ICC profiles.
Rendering intent |
Best used for |
Equivalent ICC rendering intent |
---|---|---|
Photographic - Typically results in less-saturated output than presentation rendering when printing out-of-gamut colors. This style preserves tonal relationships in images. |
Photographs, including scans and images from stock photography CDs and digital camera images. Photographic scales the grayscale tonal range in the source to the available tonal range in the output device. |
Image, Contrast, and Perceptual |
Presentation - Creates saturated colors but does not match printed colors precisely to displayed colors. In-gamut colors, such as flesh tones, are rendered well. This style is similar to the Photographic rendering intent. |
Artwork and graphs in presentations. This style can be used for mixed pages that contain presentation graphics and photographs. Presentation increases contrast for grayscale content. |
Saturation, Graphics |
Relative Colorimetric - Provides white point transformation between the source and destination white points. For example, the bluish-white color (gray) of a monitor is replaced by paper white. This style avoids visible borders between blank spaces and white objects. |
Advanced use when color matching is important, but you prefer white colors in the document to print as paper white. Relative Colorimetric, the default rendering intent for grayscale, preserves the appearance of gray when compared with output from previous Fiery products. |
Relative Colorimetric |
Absolute Colorimetric - Provides no white point transformation between the source and destination white points. For example, the bluish-white color (gray) is not replaced by paper white. |
Situations when exact colors are needed and visible borders are not distracting. Absolute Colorimetric can introduce gamut clipping in high light and shadow details. |
