It's been over a year since I had some prints made by Costco (Yonkers, NY) and I don't remember some of the details for the procedure. Last time the prints came out fine, matching the version on my monitor with the one in my print viewer, both matched to each other, so I must've done it right. My questions:
1) I edit in ProPhoto space, and 16-bit color, and save the file in PSCC, which goes back to Lightroom. Before I softproof in LR with the Costco profile, do I need to convert to 8-bit color?
2)Can I leave the file in ProPhoto editing space, or do I need to convert to aRGB?
3) I copy the files into a folder on my desktop to link to and send to Costco. Do I export the softproofed files from LR to the folder, or do I edit them in PSCC as copies with LR adjustments and them save them to the folder?
3) After softproofing in LR, should I convert the file to the Costco profile before sending it to Costco to print? Or would that end up double-profiling the file?
Thanks much...
