Absolute Colorimetric is a rendering intent that leaves colors that fall inside the destination gamut unchanged. It does not expand or compress the whole gamut. Each color is transformed into itself, if it exists in the destination gamut. Otherwise, it is transformed to the closest color at the gamut boundary. In short, out of gamut colors get clipped.
A rendering intent that aims to maintain colour accuracy at the expense of preserving relationships between colours, used to predict how images will appear when printed on a paper or other substrate with a distinct colour cast, such as newsprint. With absolute colour metric rendering intent, colours that fall inside the destination gamut remain unchanged, while out-of-gamut colours are clipped. Colours are not scaled to the destination white point.
A rendering intent used to convert out of gamut colors. For in gamut colors, maps color to color between source and destination color spaces. For out of gamut colors, remaps the color to the closest in gamut color. Does not remap source white to destination white but rather converts white as a color, so whites may look different once converted to the destination color space.
