I think I found a PERFECT solution for me.
I have a little over 50 of my comics framed and matted; comic (in Mylar) over the matting, with UV plexiglass in front (a nice sandwich, also slowly presses the book over time!). But over 15 years on the walls I am starting to get paranoid about the colors (red goes first) slowly fading, especially on some of my more valuable books (like X-Men #1 2.5, Avengers #5 5.5, Journey Into Mystery #83 4.5; all with nice red titles)
So I did this: I have been scanning most all my comics for insurance/inventory purposes anyway (front and back cover). I then take the front cover scan and print it out, matching color and size perfectly (Epson P800 using 8 1/2x11" Epson Semi-Gloss paper). Then cut it and place it on top of the Mylar so it lines up perfectly with the real comic, then place the plexiglass back on top. It looks great! So in a way it's cheating, as you are not looking at the actual comic, but the real comic is right behind. You still have the 3 dimensions and can see that there is a real comic book there. And while I can see the difference between a comic with the printout in front next to one that's the actual comic (as I know), I have had several friends over and just asked them, "Do you notice anything unusual about my comics?" Not a single one saw anything. I had to point it out to them, and even then a couple didn't quite get what I was talking about. So visually it looks great, and the point is displaying awesome works of art, and now I have no concern of any (more) fading over the next 10, 20, 30 years (I am 55 now) that they will be hanging on my walls.
Look at my picture below. Zoom in. The Iron Man/Sub #1 is the REAL comic. For the X-Men #1 you are looking at the printout of the scan of the real comic, sitting over the real comic right behind it. Can you tell the difference? From 10 feet away you can't tell (unless you actually know). You have to look up real close and know what you are looking for.
