Gamblin 1980 Oil - PR122 Quinacridone Magenta
Gamblin’s approach is different. 1980 colours contain pure
pigments, the finest refined linseed oil, and marble dust (calcium carbonate).
Since oil painting began, these three ingredients have made more affordable
colours.
Painters experience true colours without homogenized texture
or muddy colour mixtures. Gamblin's approach to using traditional raw materials
and processes ensures that artists experience the luscious working properties
they expect from their oil colours.
Quinacridone Magenta: Coolest quinacridone red. It makes
high-key tints and, in mixtures, makes beautiful transparent violets.
Quinacridone pigments generally have relatively low tinting
strength. For this reason, quinacridone colours are often expensive because
more pigment is required in the formulation.
PIGMENT COMPOSITION AND PERMANENCE
- Pigment Name: PR122 Quinacridone Magenta
- Pigment Type: organic, quinacridone
PROPERTIES
Quinacridone Magenta is a semi-transparent, robust
bluish-red with an impressive mixing range. It makes an excellent glazing
colour and is one of the bluest Quinacridone colours. The pigment's properties
vary considerably, depending on how it is ground.
Quinacridone pigments generally have relatively low tinting
strength. For this reason, quinacridone colours are often expensive because
more pigment is required in the formulation.
PERMANENCE
Quinacridone Magenta offers excellent lightfastness in most
media, but some have argued that it is less lightfast in watercolour form.
Although Quinacridone Magenta received only a passing grade of the fair under
ASTM test protocols, other test results have rated the pigment from very good
to excellent. Transparent reddish violet pigments generally have more problems
with lightfastness than any different range of colours.
PR122 is often used as the Magenta of CMYK (four-colour)
process printing because it offers a better trade-off between tinting strength
and lightfastness than other pigments in its class.
TOXICITY
Quinacridone Magenta has no acute hazards. Overexposure to
quinacridone pigments may cause skin irritation. Quinacridone pigments contain
a compound found to be a skin, eye, and respiratory irritant.
HISTORY
Quinacridone Magenta came from a red violet aniline dye
first produced in 1858 by Natanson. It was called Magenta to commemorate a
battle in Magenta, Italy. Over time, Magenta became the standard colour name
for a deep, violet red.
Although quinacridone compounds became known in the late
19th century, manufacturing methods to make them practical for use as
commercial pigments began in the 1950s.
PR122 has become particularly popular in formulating Magenta
for CMYK process printing.
