Phil: Intaglio processes are any print making process
where the image area is below the flat surface
of your printing matrix or plate.
Within intaglio, there are several different types
of processes.
One of those is the dry point.
What dry point is is a direct scratching or moving
of the material on the plate.
If I were to take one of our etching tools,
in this case a steel scribe, and scratch the surface
of this plate, that scratch will raise a burr,
where the metal was then moved from side to side.
In dry point, we're typically not removing metal,
we're actually moving it and the burr that is raised
from moving that metal holds ink.
Where that ink is held creates a fuzzy line,
which is the characteristic line for a dry point.
In working with a roulette,
now that I have my composition laid out with basic lines,
I'm going to use the roulette to start to add some tone in.
This roulette is offset dots.
The purpose of all of the different types of marks
that I'm using is to create different textures
and varying tones, so that the composition
that I'm working with doesn't feel flat
by something being made from all of the same type
of mark.
Steel facing increases the strength of the surface
of the plate, which is extremely important
for things like dry point where you have a delicate
and fragile burr that's raised up above the plate.
This will help the plate remain strong
so that none of the burrs break during printing.
Many of the same tools that we use for dry point
are also used for etching.
Etching involves several steps.
The first step is to prepare the plate,
which involves polishing and cleaning,
so that there are no marks or scratches on the surface
that could interfere with the artist's drawing.
The second step would be applying a ground
to the plate.
Hard ground is typically made from asphaltum, wax,
and rosin.
It acts as an acid resist, protecting the white
or non-image areas of the etching plate.
Preparing that ground so that it is dark enough
to see the copper showing through
wherever the ground has been scratched away.
To smoke the plate, the plate is held upside down,
so that the ground can be heated and absorb the soot.
Once a plate has been prepared with a ground,
the surface is a jet black.
Drawing a plate involves scratching away the ground
so that copper is revealed.
This is different than dry point.
Dry point's scratching of the plate is to create a burr
or to move metal.
In this case, we're actually only barely scratching
the surface, just to remove the ground.
Wherever copper is showing through that black ground,
it will be etched or eaten away to create a trough
for ink to sit in.
The copper lines become the image that will be printed
onto paper.
The third step in etching is etching the plate.
This is a process of eating away
all of the bare copper areas showing on the plate,
deep into recesses that will hold ink.
The plate is etched for 15 minutes, then it is pulled out
and rinsed and replaced back in the bath
for an additional 15 minutes to create a fine, even,
black line.
Once the plate has been etched,
the ground has been removed,
and the plate has been cleaned, it is now prepared
for printing.
All intaglio processes are printed in the same format.
Printing involves wiping the plate with ink to force ink
into the recesses of the plate, utilizing tarlatan
to remove excess ink from the raised surface
or upper surfaces of the plate, and finally,
a small amount of hand wiping and cleaning of the edges
so that all of the white areas of the plate remain white.
A small amount of chalk on the fingers will remove
any residue ink from the edges and non-image areas
of the plate.
Once the plate has been wiped, it is set on the press.
A dampened sheet of paper is laid on top and it is run
through the press with felts at high pressure.
Artists like intaglio processes
because it's a very sculptural way of working.
That sculptural process of manipulating a metal surface
is evident in the final print with raised ink
and embossed edges.
