Serigraph is the term used to define an
original, hand made fine art print produced
using the screen printing process. While the
screen printing process is used only in the first
step of the creation of an H.C. Porter mixed
media piece, a serigraph is created utilizing
this process exclusively. In contrast to the
artist's multiple original mixed media paintings,
each serigraph in the edition looks the same.
Because there is a limited number created, the
prints are referred to as limited edition
prints. Each serigraph is signed and
numbered by the artist.
The creation of a serigraph involves several
- First, a separate stencil is created for each color.
- Then, using the stencils, a separate silkscreen is prepared for each color.
- The original prints or serigraphs are then printed by forcing ink through the prepared screens, one color at a time.
- The colors are layered one on top of the other working from dark to light. This printmaking technique creates the final multi-color serigraph.
Each print is numbered as a fraction - the
number of the particular print over the total in
the edition. Since each print is produced
individually, the first numbers in the edition are
no more valuable than the middle or last
numbers. The artist's signature on the print
finalizes the acceptance by the artist that it
meets her approval. When the edition has
been completed, the screens and the stencils
1. As master chromist, H.C. (Chris) Porter hand paints each color separation using black, opaque ink. A separate film positive representing each color in the serigraph must be made by hand.
2. The screen is coated with a light-sensitive
emulsion and is then exposed to UV light. This
process hardens the emulsion in the areas that
are not black, thus transferring the image from
the film to the silkscreen for printmaking.
3. The screen is carefully washed to ensure the correct open image areas.
4. All of the inks used are mixed by hand to create the specific color needed
5. Each print is made by printing 1 color at a time. With each new color, the screen is changed on the press.
6. The artist inspects the prints carefully before, during, and after each new color is applied.
