In this example of a etchingVermont Castles,
plate size 7" x 9.75", by Luigi Lucioniyou can
see some useful points.
The upper enlargement shows the fine detail and
precise line quality possible in etching. The lines are often
reminiscent of fine pen-and-ink drawing.
In the next lower enlargements,
the arrows point to the edge of the printing plate. While its
indentation into the paper isnt clearly visible here, we
can see that the edges are left a bit darker, with a bit more
ink. This is intentional. When the artist wipes the excess ink
from the plate, the edges are often wiped more lightly, letting
the ink around the edges create a visual border just slightly
darker than the area they enclose. This is useful in light-colored
areas, like the upper right corner of sky in the lowest enlargement.
Note also the very fine complex, faint lines that portray the
clouds.
The bottom enlargement is of an etching plate by Lyman Byxbe.
This metal plate was inked and then printed, with the final print
showing the reverse of what we see here. Faint remnants of ink
down in the etched lines make the image visible.
