Client printing images?

If you offer images to your clients on cd or flash drive, do you specify/recommend where they should have them printed?

I was just thinking that all your effort in making the best image possible could be quickly trashed if printed at the local drug store.

It is because of this reason that I don't offer full-res digitals. I offer small (usually 800px on the long edge) files that they could upload to Facebook or email to friends/family as they wish... but this is only for the files that they have purchased prints of. I figure in most cases the client wants to share their favorites, not the ones they don't like.

Can they get a 4x6 out of that file, sure. But an 8x10 and larger isn't going to turn out looking so great (particularly in comparison to the full-res).

Those that are willing to pay for the files, yes I recommend the consumer division of my pro lab. I also tell them that I cannot be held responsible for how the files print due to differences in printers.

I recommend places if they ask. I can't stop them from picking the worst printer in the city. I think they know what a good print looks like though. Some clients prefer me to print even though they purchased the digital files. Either they don't want the hassle of doing it themselves, and/or they want it done the right way. That and I do additional retouching for prints and guarantee the end result.

I recommend printers, but they go to Walgreens anyway.
