Rendering Intents

The first four rendering intents are defined by the ICC Consortium.

Perceptual

Profiles created with different programs may be different, especially with smaller gamuts.

• Perceptual: Perceptual rendering intents compress the entire color space into the printer's color space while maintaining the relationship between all the colors and adjusting for both the white point of the media and the black point of the printer’s gamut.
  All colors are compressed relative to each other.
  
• Saturation: Saturation differs from Perceptual in that all colors are scaled while preserving the saturation and at the expense of the hue.

Corlorimetric

Profiles created with different programs will create

• Relative: Relative renders out of gamut colors, preserving the lightness and hue of the color, and adjusting for the white of the media.
  There is compensation for white, so white will always be white.
• Absolute: Absolute renders out of gamut colors to the boundary of the printer’s gamut and makes no adjustment for the white point of the media.
  The biggest difference will be seen in shadows as there is no adjustment for substrate.

The following rendering intents are not recommended for DTG printing.

• Standard Compression: Suitable for all gamut types of different sizes. Calculates a conversion that is perceptual for input and target profiles.
• Black point Compression: Preserves image definition in highlights and shadows when converting from large to small gamuts. Neutral tones are converted with colorimetric and out of gamut colors are lost.
• Dynamic Compression: Minimizes out of gamut areas by comparing the source and target color spaces. Preserves brightness and reduces saturation to preserve image definition. The gray axis is relative to the target paper white.
• Absolute Compression: For similar gamuts and different paper tones, where gray compensates for paper color.
• Minimum White Compression: Similar to Absolute Colorimetric with only white point compensation. Does not simulate paper white, but can achieve a close match between source and target color spaces.

The following two rendering intents are useful for blending rendering intents. These are equivalent but not exactly the same as the intents above (Relative and Absolute).

Note: Used for blending rendering intents.

• Relative Colorimetric
• Absolute Colorimetric
• Minimum Compression: Similar to Absolute Colorimetric with only black and white point compensation. Does not simulate paper white, but preserves image definition and gives maximum shadow contrast.

Optimize the color conversion of a secondary color plus black to prevent contamination.

Select to convert the triplex color to the most suitable color represented in the target color space consisting only of the triplex colors.

Note: Contains exceptions: Duplex, Primaries, Secondaries, Gray, and 100% Black.

Optimize the color conversion of a primary color plus black to prevent contamination.

Select to convert the duplex color to the most suitable color represented in the target color space consisting only of the duplex colors.

Note: Contains exceptions: Primaries, Secondaries, Gray, and 100% Black.

Protects single-color structure of Black from 0% to 100%.

For RGB, Gray ensures gray is composed of equal RGB value proportions.

For conversion from RGB source to a CMYK target, Gray ensures gray is black only.

Note: Contains exceptions: 100% Black, and White.

Ensure black is always 100% K, 0% CMY.

For conversion from RGB (0,0,0) to CMYK, ensures black is 100% K.

Calculates the best color correct vale with the highest level of saturation.

R, G, B corresponds to combinations MY, CY, and CM.

Maximum saturation (100%) of the higher color value and the second color value is optimized colorimetrically.

Note: To ensure 100% red remains 100% red, use 100% RGB.

Protects single-color structure of primary colors.

Calculates the L*a*b value of source profile primary color and finds the best primary color match in the target profile.

Note: When disabled, can cause color contamination of primaries in the target profile.

Select individual primaries to allow protection of individual primaries.

Protects the two-color structure of secondary colors.

Calculates the L*a*b value of source profile secondary color and finds the best secondary color match in the target profile.

Note: When disabled, can cause color contamination of secondaries in the target profile.

Select individual secondaries to allow protection for individual secondaries.

Protects paper white. Use for absolute colorimetric simulation for proofing.
