File format for print?
6 months ago

So, I happened to come across 500px file specifications for print, and I'm a tad bit confused. I thought jpgs could only be 8-bit? Is there actually a way to keep pro-photo 16-bit as jpg exporting via PS CS6+??

"Requirements for Canvas Print sales:

  • No watermarks, signatures, or borders please!
  • Uploads must be JPG/JPEG files
  • Photos must be at least 3000 pixels along their longest side
  • 8-bit or 16-bit color
  • Colour profile must be embedded in the file sRGB, Adobe1998 or ProPhoto"
