Drawings made upon these grained and ridged papers must not be stumped down or treated in any way that would fill up the interstices, which give the lined and granular effect capable of reproduction by line-process. Also, it is very important to note that drawings on these papers can only be subjected to a slight reduction of scale—say, a reduction at most by one quarter. The closeness of the printed grains and lines forbids a smaller scale that shall be perfect. Mr. C. H. Shannon has drawn upon lined “scratch-out” cardboard with the happiest effect.
