Rendering Intent
The rendering intent tells Photoshop how you want to handle "out-of-gamut" colors. Out-of-gamut colors are those colors that are contained in the image that the printer cannot reproduce. You will have four choices in this selection:, , , and
-
- Perceptual rendering intent shifts all the colors so they are within the printer's gamut and attempts to maintain the relative color relationships. This rendering intent is useful for images with a lots of out-of gamut colors.
-
- Saturation rendering intent maximizes the saturation of colors. This is not a good rendering intent for photographic images. It is useful for graphics where bright, eye attracting colors are desired.
-
- Relative Colorimetric rendering intent shifts the out-of-gamut colors so they are within the printer's gamut, but leaves in-gamut colors where they are. More importantly, this rendering intent maps the white point source space (image file) to the white of the media (paper). This is a good rendering intent for images that have few out-of gamut colors and for media that has an off-white color.
-
- Absolute Colorimetric works in similar fashion to relative Colorimetric, except is does not map the white point to the media's. This rendering intent is used mostly in proofing when there is need to simulate the quality of one printer on another.
In most cases, you can use either Perceptual or Relative Colorimetric rendering
intent. If you want to learn how to preview the difference (soft proofing) see the WYSIWYG
section.
Black Point Compensation
Black point compensation maps the black of the image's color space (gamut) to the black of the output device. Leave this box checked every time you print. Black point compensation will not take care of all of your needs in the area of shadow detail, but it will when in conjunction with proper black point settings,
