Help! Photoshopped images printing badly

[notstarvingartist]

Hello
I am fairly new to Photoshop and photography. I have been working on some images I took of a friend. I used Topaz adjust for some of the editing to help give the photo a grungy/hdr look. I looked at the images full size on Photoshop and they turned out great. However, when I sent them to her, she put them on facebook and then tried printing them online. The facebook and the printed images came out terrible. The skin looks splotchy and has weird tones in it. I resized them to 800x600 and they are still terrible.

Any hints?
Thank you!!

Resolution will not affect this: its a colour space issue, mainly.

Facebook compresses images that it puts onto it's servers. The first thing to be compresed is the colour palette. Your images done with Topaz likely have alot of bright or powerful colours that are being splotched out.

Much the same with printing: most printers work in CMYK, which is a much smaller colour space than RGB. This is why they come out similarly blotchy.

Generally speaking, heavily edited photos dont do well when printed or when compressed.
