After rereading the thread on Evan's dials, I had a thought on getting various stocks for labels. I had to design some adheasive labels at work and needed a sheet that would work well in ink jet printers for continous production. we have worn out several printers by now. Each label was different but the size and pattern was the same. My local print shop was able to obtain several samples of printable stock for evaluation. They run into this on a daily basis and have sources for label stock from around the world. You would probably have to buy a hundred sheets or more but they can get almost anything and you can specify what you need.
Make it fit.
You can't win and there is a penalty for trying!
