      Hi Fritz,

      That's good news on the black trucks. I'm not in a museum but if you've
      seen pictures of my shop the white would have stood out like neon. Just an
      aesthetic thing on my part.

      I'm definitely going to experiment more including trying some coated
      paper. Presently I have only rubber base ink. Any recommendations on a
      particular paper or ink?

      Very interesting, and I appreciate the information. I am getting ready to try my first. It will be only 100 lines. The engraver didn t think he could do

        Very interesting, and I appreciate the information. I am getting
        ready to try my first. It will be only 100 lines. The engraver
        didn't think he could do anything finer, but 100 was all I wanted.
        Maybe I'll try to find another supplier eventually. I will use
        VanSon's oil base ink. I don't have time to order anything
        different, and if it doesn't work, I'll do a different project
        without halftones.
