ART & MURAL
This past week we got a call from a customer regarding
touching up and repairing a digitally printed
wall paper mural - if we possibly could. The problem was that some facets of
the digitally printed wall paper did not match, did not line-up. See images:
Airbrush artist, Ray Gatica has been airbrushing for over thirty years and goes back to the time when all photo retouching was done with the airbrush not digital computer programs like Photoshop of today. Back then we also had to mix and match colors for the particular at hand project.
Our experience in doing this goes to Gatica's
experience in photo retouching with the airbrush. The touch up was done with the airbrush using acrylic
paints. Luckily the wall paper had a mat-finish. This worked out in our favor
because the acrylics can be sprayed to match the mat finish. But also if you
spray the paints wet and heavily they can turn satiny or even shiny, which is
not what we wanted in this case. What can happen in a situation like this is
that the repair can be a different sheen than the existing wall surface and
not look good because the repair will stand out.
Actually the job was a photo retouch project like we used
to do back when all photo retouching was done with an airbrush, before the
days of modern computers and PhotoShop for photo editing. We go back to them
days when it was done by hand. We saw this was a large photo editing.
On the Process: Since there were no brush strokes on the
existing surface the airbrush is the best tool for this because it leaves a
smooth finish. A Paasche, VJR airbrush was used for the whole thing because it
is a small and precise instrument. And you can use small amounts of paint like
a few drops at a time and they go along way. The hardest thing in most of
these touch-up mural repair projects is to mix to match the colors on the wall
to do the repairs. This requires experience with mixing colors. We are adept
at this and can match any color – no computer needed.
The basic color mix starts out with the red, yellow and
blue; and white too change the color hue a bit if necessary. It is said that
white is the absence of color and black is the saturation of color involving
the full range of the red, yellow, blue colors.
When airbrushing a mural repair, you run the possibility
of over spraying too much on to the area being repaired. In order to prevent
this we use shields. We make our
own shields out of hard acetate or clear plastic sheets. The shields are
shaped in curves and are used similar to old French-curves used by designers
and architects. They are used to isolate the paints/colors to specific areas
and protect the areas we do not wanted painted.
Most of the time we have to mix and match colors, this is where our color matching experience from our airbrush photo retouching days comes in handy.
After the repairs and the finishes match there usually is
not much else to do as far as applying a top coat. Usually the paints dry and
are permanent. In the event the finish and the repair do not match a clear
coat may have to be applied.
This was an interior mural in a Dentist office but we
have also repaired exterior.
