Short answer
A rendering intent is the rule a colour-managed conversion follows for colours and tones the destination cannot reproduce. ICC profiles offer four: perceptual, saturation, relative colorimetric and absolute colorimetric. Relative colorimetric with black point compensation suits most graphics and images that are largely in gamut; perceptual suits photographs with a lot of out-of-gamut colour; absolute colorimetric is for proofing one print condition on another.
Every conversion to print has two mismatches to handle: colours outside the press gamut, and a tonal range that is shorter at both ends — the paper is darker than the source white and the ink black is lighter than the source black. The ICC defines four intents because there is no single right trade-off. Colorimetric intents reproduce in-gamut colours as measured and clip the rest to the gamut edge. Perceptual and saturation intents compress the whole range so that relationships between colours survive, at the cost of changing colours that would have fitted.
Absolute colorimetric reproduces colours exactly, including the paper's own tint: if the source paper is yellower than the proofing paper, the proofer lays down a faint yellow tint in blank areas. That is what proofing needs. Relative colorimetric maps source white to destination paper white, then reproduces everything else colorimetrically and clips what does not fit; highlight detail survives but shadow detail below the destination's black can merge. Perceptual compresses the full source range smoothly into the destination; the exact curve is left by the ICC to each profile maker, so perceptual results vary between profiles. Saturation favours vivid colour over accuracy and is meant for business graphics, not photographs.
Black point compensation (BPC) fixes relative colorimetric's weak end. As well as mapping white to white, it maps the source black to the destination's darkest black and scales the tones between, so shadows keep their separation instead of clipping into a flat block. The ICC describes relative colorimetric as having little value without BPC in most workflows and recommends offering BPC for perceptual and saturation too, where it is harmless. The one case to leave it off is absolute colorimetric proofing, where the proof must show the real black of the simulated press, weak or not.
For logos, illustrations and brand colours, relative colorimetric with BPC keeps every printable colour exact and only moves the unprintable ones — check them in a soft proof. For photographs with saturated skies, flowers or neon light, perceptual avoids banding where many out-of-gamut values would otherwise land on one edge colour. When the source gamut is small (an sRGB image going to coated offset), the two intents give nearly identical results. For a contract proof, the proofing software uses absolute colorimetric from the press condition to the proof printer, and that should not be changed by the designer.
| Intent | Paper white | Black | Out-of-gamut colours | Typical use |
|---|---|---|---|---|
| Perceptual | Mapped to paper | Compressed to destination black | Whole range compressed smoothly (profile-specific) | Photographs with much out-of-gamut colour |
| Saturation | Mapped to paper | Compressed | Pushed towards vivid colour | Charts and business graphics |
| Relative colorimetric | Mapped to paper | Clipped unless BPC is on | Clipped to nearest gamut edge | Graphics, brand colours, most images with BPC |
| Absolute colorimetric | Source paper simulated | Source black reproduced where possible | Clipped | Contract proofs and press simulation |
Why: Relative colorimetric without black point compensation clipped everything below the press black.
Fix: Switch BPC on, or use perceptual for that image.
Why: Absolute colorimetric is simulating a darker or yellower production paper — which is correct for a proof.
Fix: Judge it as intended; if a paper tint is not wanted for a design preview, use relative colorimetric instead.

StandardStrong evidence
The ICC profile specification provides four rendering intents: perceptual, saturation, relative colorimetric and absolute colorimetric.
Source: White Paper 40: Black-point compensation — theory and application; International Color Consortium: specifications and information
FactStrong evidence
Black point compensation maps the source's minimum luminance to the destination's minimum as well as white to white, and the ICC recommends it particularly for relative colorimetric, which it describes as having little value without it.
Source: White Paper 40: Black-point compensation — theory and application
FactStrong evidence
The shape of the perceptual intent's tone and gamut compression is not defined by the ICC and is left to each profile creator, so perceptual conversions differ between profiles.
Source: White Paper 40: Black-point compensation — theory and application
ConventionModerate evidence
Relative colorimetric with BPC is the better default for graphics and mostly in-gamut images; perceptual is the better default for photographs with large out-of-gamut areas.
Caveat: A widely followed convention, not a requirement; judge by soft proof.
