Here is a picture of something I mentioned earlier, a new process used on PBT.  
(Ignore the size of the keycap)
It's suppose to be a permanent print, but you can feel the legend.  In my opinion, it's not as great.  It is a lot cheaper, and it is used on PBT keycaps.  In my opinion, Cherry PBT keycaps feel really nice.  

I swear, I feel like I owe you guys a picture of something else.
