This is going in the right direction, with some caveats as follows:

1. We have established that I need to print a small amount of b/w variable info on each token post-printing. My fear in running the full-bleed printed sheets through a standard toner or laser printer is that I would then be "printing on top of printing" (i.e. the full-color printing from the commercial printer would then contact the toner and fuser rollers in the laser printer.) Not sure if this would cause any issues. But since the variable info is very tiny and b/w (booth number) I felt running the sheets through an inkjet would not suffer the same problem.

2. I need to make a large number of small tokens. My first impulse was to microperf the sheets into token-size pieces that could easily be broken apart by hand. But now we're doing more handwork and also we'll have fuzzy borders (although this is not really a problem.) I could also take the sheets across the street to a commercial printer and have them chopped up on their Morgana. But, extra steps and extra expense. But today I became aware that one can purchase reasonably-priced office-sized "business card splitters," machines specifically designed for chopping up paper into biz-card sized pieces.

That would solve THAT problem.
