Oh yes, thanks so much for your help! I got the specific profile from the printer and the posters turned out amazingly! THANK YOU!

Ok - thanks. I will be sure to find out and get detailed instructions from the lab.

Some people in this world are just incredible aren't they.

Thank you! Lifesaver. Will dive in now.

Gosh, actually, no. I've prepped these posters for a charity event and they are waffling on what printer to use at the very last minute ($ issues - but we need these foamcore mounted and in hand by next Friday) and they asked me not to contact them until finalized. All I know is CMYK. Attached is screenshot of a poster. I didn't create any elements full bleed. I designed to 300dpi - and the images are already being scaled up.

I'm printing posters at 3'x4' in size (36"x48"). I created them in Photoshop. I created them in RGB but lab wants CMYK. When I convert it will flatten (in case that's relevant info?). My question is: what file format am I best to export as to submit for print? Are there any issues around text I need to worry about? TIA.

I'm coordinating a photographic display for a charity and working with a range of amateur to pro photogs. We need to print posters at 36"x48". What MP (or other guideline) do I need to give photographers for minimum gear requirements to print acceptably at this large size? I'm not looking for DPI math, but a practical answer that account for viewing distance, etc. Thanks.

I have a Mac laptop running OS X El Capitan 10.11.2 and Lightroom 5.7. It is over 2 years old, and has 16GB of RAM. Its hard drive has 50GB free out of 500GB. The last time I shut down was more than 2 days ago. I have never run a cleanup program.

I create the 1:1 previews, and if I work on the files right away, the performance is good, but if I come back the next day, say, or a couple of weeks later, they no longer load quickly - like the 1:1 preview has disappeared. SOMETIMES rebuilding the 1:1s is possible (so indeed it had disappeared), but other times it claims to be already built, but the full-size view still takes an age to load. This has been happening a long time (years), but I've never been able to find a solution. Anyone have any ideas? thx
