No way via Lr proper.

Easy enough via plugin, but the only ones I know that support it are those wired to mogrify, where you can include additional command-line parameters, e.g.

* Lr/Mogrify

* PreviewExporter

command line parameter is '+profile' (seems like it should be -profile, but it's not).

Untagged images are BAD! If you had a few hundred images (times 1.87mb) on a slow transfer, OK maybe.

Depends on the lab or service. In CMYK workflows, folks by and large just send the numbers within the data to the device as is. The only use for an ICC profile would be if someone wants to open the image and view it correctly (or edit it). In such workflows, it is common for such shops to receive maybe hundreds of output ready CMYK files. Even at 1mb per image, it adds up. Even so, unless bandwidth is an issue, I still recommend an embedded profile. In the very old days (1990’s) some old RIPs would barf on an embedded profile so people stripped them out. I seriously doubt those RIPs are still running and if so, I’d be worried to work with such a shop.

Lab’s that can accept output ready RGB should work the same way. But there are far more labs that expect sRGB and if the OP sent data in something other than sRGB, the front end would make a mess of the output. You’d want an embedded profile assuming the front end can even recognize it and pop some alert.

Perhaps I should have mentioned that I am not dealing with a full service lab, but rather my local Costco which has custom profiles on DryCreek.com. The local personnel do not know a lot about color management, but there is an option on uploading to print the files with no adjustments and they are sent directly to a Fuji Frontier printer. I do most of my more important printing with my Epson 3880, but send small prints to Costco and have have good results without embedded profiles saved as such from Photoshop.

I have sent some prints to CostCo using their custom profiles and left the profile in place.  The CostCo I used simply ignored the embedded profile.
