The physics of printing is to transfer ink from the completely flat
surface of the face of type (or plate) to the extremely rough surface
(microscopically) of paper. To get a clear impression you have to
transfer ink from the entire surface of the type to the corresponding
surface of the paper. Because the paper surface is irregular, you
will initially only transfer ink to the highest parts of the paper.
There are basically three things you can do to get ink into the lower
parts of the paper: 1. Use gobs of ink, which is a generally a
disaster, but sometimes necessary when printing from large wood
types. 2. Apply more pressure so as to give a heavier impression
and use a hard backing. The type can thereby crush the paper. This
is what we are basically doing most of the time. It works well with
much general work, especially on either soft or smooth papers. 3.
Dampen the paper to allow the type to flatten it with much less
Working with a hand press, which applies pressure of the entire
platten uniformly, I find that dampening the paper is often
necessary, expecially with linoleum blocks or other large solids. I
would not think it would be as important if you are using a cylinder
In any case, the paper should only be slightly dampened. There is a
lot in the archives about this topic.
