I created a poster in Photoshop and it in CMYK mode because it is going to be printed (not used on the web at all). I saved it as a JPG (also in CMYK) and when I sent it to someone in an email and they downloaded it, they sent me a screen shot and it looks neon colored. I understand this happens because screens are in RGB, but my questions is:
Will it print almost exactly how it looks when I created it in CMYK? (When I opened the JPG on my computer, it looked the same as when I created it in CMYK in Photoshop)
It was originally a light pink color (in CMYK) and on screen when downloaded it looks bright purple.
Thank you in advance!
CMYK Jpeg, while valid, has limited support in software, especially in browsers and in-built OS preview handlers. It can also vary by software revision.
It may be better for you to export an RGB Jpeg file for your clients preview use or provide a PDF or CMYK TIFF instead.
