Clear decals have an advantage of the paint being the background color thru the tanslucent film Mine doesn't illustrate that, but in some places there is just no good substitute for a translucent reviel of the paint as background.
Printing ink also has a MUCH higher pigment count than liquids in jet printer or toners, etc..
The home printer will do for most things, but there is no substitute for "real" printing if you need the best in ink quality.
The decal I made looks better than the Lionel stickers on my RI&P General. in person it looks far closer to being painted on than stuck on.
