[Taxacom] Scale bar design when imaging herbarium sheets

[Matt Buys]

We are in the process of designing new scale bars for inclusion on herbarium
sheets destined to be imaged.  A brief perusal of such images via Google
reveals a rather similar design being employed by the major herbaria, i.e. a
black background, with text and ruler markings in white, centimeters
designated by alternating black and white sections, the first centimeter
only subdivided into millimeters, etc. Is there a some kind of best practice
convention that is being followed?

Yours
