GOLDEN Silkscreen Medium is a water-borne system designed to
blend with acrylic paints for silk-screen application onto paper,
wood and other suitable fine art materials. This product is designed
to increase working time and prevent paint from drying in the
screen too quickly.
NOTE: GOLDEN Silkscreen Medium is NOT intended for use on
fabrics to be laundered. Use GOLDEN Silkscreen Fabric Gel for
Although any addition of GOLDEN Silkscreen Medium will increase
the open time1 of a paint, a good starting point
is to blend even parts of paint and medium. Higher levels of the
medium will increasingly affect the transparency, but also will
increase the open time. Lower levels of Silkscreen Medium produce
mixes with the greatest opacity2, but that are
more likely to clog in the screen.
Mixing With Other GOLDEN Products
GOLDEN Silkscreen Medium can be blended with any of the GOLDEN
Acrylic paint lines, Gels and Mediums to lengthen the working
(open) time for silk-screening. It is a pourable blend of acrylic,
retarder & water that, unlike retarder alone, will form a
film, thereby increasing durability and thinning the paint while
retarding the drying time.
Silkscreen Medium is not designed to impart opacity. The
opacity of the mixture will be determined by the nature of the
color being used and the ratio of paint to medium used. Higher
levels of the Silkscreen Medium will be increasingly more transparent.
Adding GOLDEN Titanium White to a mixture will increase opacity.
Any addition of white will lower a color's chroma and value.
Additionally, transparent colors, including Iridescent and Interference
Colors, can be made to appear more opaque when a "base coat"3
is screened first. For example, GOLDEN Iridescent Gold will appear
to have greater opacity over a buff-colored base coat. Refer to
screen-printer's books and other reference material for further
(Consult GOLDEN Pigment Identification Chart to determine
the opacity ratings for the various colors).
General Product Information
Do not mix with oils. Paint on any non-oily surface. Abrade
non-absorbent surfaces for increased adhesion. Minimum film formation
temperature is 49oF/9oC. Avoid freezing. Clean screens/tools with
soap and water. Safe to use with minimal odor.
Thickness, also termed
"viscosity," can greatly influence how a printing ink
performs. Thinner inks have a greater risk of "bleeding"
into the paper or other porous substrates, but perform well on
tighter mesh screens and dry quickly on absorbent substrates like
paper. Thick, pasty mixes have a higher tendency to clog tighter
mesh screens, but can offer increased opacity (due to a thicker
film) and are less likely to bleed when screened onto fabrics.
These considerations should be addressed before beginning large
Choosing a line of GOLDEN Acrylic
Paints to use with the Silkscreen Medium depends on the thickness
needed for a particular job. GOLDEN Heavy Body Acrylics have a
buttery viscosity and will therefore make thicker screening inks.
GOLDEN Fluid Acrylics have the same pigment load as our Heavy
Body Paints, but are the consistency of heavy cream, and are quite
pourable. Mixtures with Silkscreen Medium will remain thin and
Improving Working Time
While Silkscreen Medium
dramatically helps to prevent paint from drying in the screen,
it does not eliminate the possibility. As soon as a clog becomes
apparent, it should be removed with a damp cloth. If the clog
is allowed to dry in the screen, it will be extremely difficult
to remove. For multiple clogs that develop, stop printing and
thoroughly clean screen with water, using a non-abrasive sponge
or cloth to remove the clogs. Pat the screen dry and continue
Work quickly, with minimal time
between prints. Have screening inks pre-made in sufficient quantities
before beginning screening.
To maximize open time, add 5 -
15% GOLDEN Retarder to the GOLDEN Silkscreen Medium/Paint mixture.
This will increase the open time, but not dramatically alter the
It is beneficial to pre-wet the screen with a water/Retarder mixture
(1:1) before screening. Keep a plant mister bottle filled with
this mixture at hand, and lightly spray the screen periodically
to prevent paint from drying. Avoid excessive misting, as this
can cause bleeding on the paper.
