Gum Printing – What is a droper Stem


Way back on 21 Feb 2012 you explained your pigment/gum/sensitzer ratios. In that description you mentioned  you use and inch of pigment to 12 dropper stems of gum and sensitizer.  How many ml is a 12 dropper stem? What is this dropper stem?  Is it a small eyedropper or something else?

The dropper stem is the what I use to distribute the solution.   I don’t know how many ml is in the dropper stem I use but I use as much solution of either gum or sensitizer as the stem of the dropper can hold. The ratio is more important than the actual amount. The post from January 25, 2012 has photos of the dropper bottle and stem:
