Digital BW, The Print

Mathew,

This is a common technique in ink/pigment labs where we use the Mayer rod
for testing small samples.  I then adapted this for use with coatings for
our prints.  It works well up to about 24" wide.  Beyond that I think it
will be difficult to manage the rod without a specially built rod holder.

The key with a rod coating is using the proper rod (wire) size for the
viscosity of the coating that you are applying...this in turn needs to be
balanced with the polymer solids in the coating.
