I sell physical prints mostly out of the fear of someone reselling. Like you said, they could still do that with a physical copy by scanning but at least that’s a little more of a hassle. I’d also hate to see my art printed on shitty paper or the colors are completely off because the buyer (or print service they use) doesn’t put in the effort to get the colors just right.
Because Apple includes applications for photo editing and creative projects in its macOS, we found most of the Mac greeting card design programs we tested have fewer editing tools than their PC-compatible counterparts. This means you may need to edit photos in another application before you upload them to your greeting card software. A few of the programs we tested have some basic editing tools, such as those for cropping and fixing red-eye, but those same programs have lower quality graphics.
