Well, I'm sorry, but I didn't mean for this to be a bash towards newbies or young people in the business. Nor what someone does or does not know, but the difference in how anyone goes about this trade these days.
Certainly, ya need talent and to be able to regconize good from bad at either level. There were some real doozies in the hand painting world, too. Not everyone was good, but the vast majority were. The fact is, there were only a handful of substrates and only one or two ways to prepare them. Ya either hand-lettered a board, truck or front window or you screened it. Yes, you can screen print windows and just about any other surface...... while they're in place on a building.
I just get a kick out of all this cut and copy and pasting of stuff, usually copying it from somewhere and calling it finished artwork/designs/layouts. No thought of any of the basic elements are even entered into the equation. Color wheel theory is not known, but PMS is. Machines do ALL the work and people get a kinda satisfaction from it. It's good to be happy and proud if you instal signs, wrap vehicles or buildings, but there's still something very rewarding and gratifying about taking something from basically nothing and making it into something, using your hands. Sculpting is something I can do, but not very good at it. I had pottery class in college and it was a lotta fun, but painting signs or doing a fine arts piece is much more to me. It's just what's in side me, I guess. No need to bash each other. Pushing buttons and knowing when to not go any further is a good skill, just not the same as was first intentioned with this thread.
