The Soft-Proofing Rendering Intent lets you choose the rendering intent for the soft-proof profile. For more details about the available choices, see Відтворення кольорів .

Relative colorimetric is usually the best choice (default). Unless you use a LUT monitor profile (most monitor profiles are matrix), choosing perceptual intent actually gives you relative colorimetric.

To get an idea how your image will look with the soft-proof profile enable View → Color Management → Proof Colors.
