Which rendering intent should I use for Lightroom soft proofing when sending files to a print service?

In Lightroom soft proofing, should I choose Perceptual or Relative Colorimetric when I’m sending images to a third-party print or postcard service rather than printing myself? If the lab doesn’t clearly state what rendering intent they use, is there any reliable rule of thumb, or should I use a generic print profile?

Seems in discussions that perceptual is the default ICC complaint version. But then I found a guide from a printing service, saying they use both depending on the medium:
"American Frame uses the Relative Colorimetric rendering when printing photographic images on glossy papers such as Epson Premium Luster Photo Paper to preserve color accuracy. When printing to canvas and matte surface papers, the Perceptual intent is utilized."
So it seems that unless otherwise noted, I should proof it for perceptual (which often changes the image most), while if the service does tell otherwise, I can proof it for relative.
Since this is all about getting out of gamut colours in gamut (smooth mapping vs cropping), the best alternative is to make sure they already are.

Generated from our catalog & community — verify before relying on it.
There isn’t a reliable universal rule. Rendering intent depends on the specific lab, paper/surface, and printer/profile workflow.
From the community examples, some labs use Relative Colorimetric for glossy/photo papers to preserve color accuracy, and Perceptual for matte or canvas where smoother gamut compression may look better. So the best practice is:
- Use the lab’s ICC profile if they provide one.
- Follow the lab’s stated rendering intent if they specify it.
- If they don’t say, ask them—guessing is not likely to be accurate.
A generic “average print profile” is only a rough approximation and may not match the service’s actual output. If you must choose without guidance, Perceptual is often treated as a common default, but that is not guaranteed.
Since the main issue is how out-of-gamut colors are handled, another practical approach is to edit so important colors stay within the target gamut as much as possible.
