leonBesides reading some books on printing I would imagine most graders learn by on the job experience. The more you handle something the better you know it....no different than us collectors in that regard except they handle far more than most of us..This is another reason I have a preference for my grading company of choice...I know the graders, know they have each graded 10's of thousands of vintage cards, and respect their opinions....best regards
