I prefer the repro glass in this case, the skin tones look much more realistic than that of the original.

and see the posting by Clay (cfh), where he says...
About a month ago Steve changed the coloring process for the shine-through areas to have increased color saturation. Now it's very difficult to tell a silk screened BG from one of Steve's, even when lit up. The whole process has evolved and now I have to say, it's pretty darn good.
Its not rocket science even though they ( Clay and Steve here) pretend its some technical process they've been through to achieve a good result...... when printing a backglass you need to " double strike" the areas where the light comes through. printing ink is very thin and it washes out when backlit... 2 layers of ink and this is resolved.
I hate it when people talk bullshit and pretend they've done something clever
