Lynn, Sorry to hear of your color problems. You may have to darken your files. My work is also traditional art, scanned etc. I'm on a mac and use photoshop -my GCU cards print pretty true to my files and look pretty close to what I see on my screen. I know with traditional art sometimes blues and greens don't scan true to the originals and you may have to fuss with them in photoshop.

Hello Lynn and welcome to GCU!  
 
Diana has given good advice and I know from purchasing one of Diana's cards in the past for my husband, her cards come out beautifully.
 
I have purchased many of my own and never had an issue.  They are always rich with color and saturation, and true to screen.
 
The only thing I will add is to make sure that your jpg is saving in a standard RGB color profile.  Some programs have a default that is set to a color profile created by the manufacturer.  
 
What I've always used with great success is:
 
Working RGB - sRGB IEC61966-2.1 or if that is not offered Adobe RGB (1998)
 
Either of these should give you good results with most POD's out there.

Hello Lynn, Just to let you know, I have, in the past had trouble with some of GCU's printing when they were making some changes in their printer or software. The colors were pale and yellowed, and appeared out of focus. I did bring it to GCU's  attention. It was an isolated incident, and there were only a handful of others who experienced the same.  It's possible that you are experiencing a similar anomaly, so I would suggest that you bring it to Shaun's attention if you're pretty sure the problem is not your scans or RGB settings.  Best of luck to you, your illustrations are very charming. Sincerely, Betty

I use a Spyder colorimeter and am very happy with it. Since using it, I have never had colour problems with my monitor again. I wrote a blog post last year on Colour Management which may be of some interest.

   Hi Lynn!
     
  Sorry to hear of your trouble with your cards. I ordered and received 4 of my own cards this week, and the colors were wonderful on all four of them. One was a photo of a sunset with a sailboat passing under the setting sun, and it came out perfect, one was a white card with a band of blue-green color with white dots, and 'Get Well, Dear Aunt' in the same blue-green color, it came out beautiful, as did the other 2. I did order all of mine in glossy. I'm not sure if that makes a difference in how the color comes out.
