The urei 1620,s in clubs were also prone to having worn away silkscreening. MY gear does not. I grab the knob towards to top, many grab the knobs with their fingertips actually on the faceplate as the turn and twiddle them. Even though you are doing this without being conscious of it, it is what is happening.
Some manufacturers now prefer to have their faceplates powder coated and powder coating is MORE durable, whether you think it looks as good is up to the individual, I prefer the look of screening.
