Almost all kinds of Prints or Engravings from Wood, Stone, Copper and
Steel may be reproduced directly. _The requisites are, clean, distinct
black lines or stipple work, on white or only slightly tinted paper.
All Photographs and Pencil Sketches must first be drawn in ink._ We
keep a corps of artists constantly employed, trained to do this work
in the best manner. We can make drawings from photographs or tin-types
taken in the usual way. They may be of any size, but should, of course,
show the object distinctly.
Drawings for our use, unless intended to be redrawn, should be on a
_smooth, white_ surface, in _perfectly black_ lines, and usually twice
the dimensions each way of the desired plate.
Copy for fac-similes of handwriting should be in _perfectly black ink_,
on _smooth white_ paper, written with a full pen, and without use of
blotting paper.
