Graphic Arts : the Q&A Colorex inks

Artist Acrylics Liquid: On what surfaces do you apply Artist Acrylics Liquid?
Artist Acrylics Liquid is a dispersion of pigments in acrylic medium and, thus, offers a very good adhesion on acetate or polyester films, photographic prints and of course the paper surfaces, cardboard and Bristol, even those that are very smooth. It is better to use thick papers (over 180 g) to prevent them from curling when wet.

Artist Acrylics Liquid: Are Artist Acrylics Liquid Inks indelible?
Yes, it is one of the major differences between Colorex watercolour inks and the Artist Acrylics Liquid acrylic inks. It is therefore possible to superimpose or cross layers without the soaking or fusion of colours.

Artist Acrylics Liquid: Are all of the colours translucent?
No, Payne’s Gray, Naples Yellow and the white are opaque. By mixing these colours, one can obscure the translucent shades.

Artist Acrylics Liquid: Do the Artist Acrylics Liquid have a good resistance to light?
Yes, these pigmentary colours do not fade, unlike Colorex watercolour inks that are sensitive to ultraviolet rays and require a varnish to protect them.

Artist Acrylics Liquid: What other products can be used with Artist Acrylics Liquid?
Acrylics and most acrylic auxiliaries may be used, such as gels, mortars, etc. For works in resist, use the Drawing Gum peelable rubber solution.

Artist Acrylics Liquid: How do you clean the brushes and other tools once the ink has dried?
This requires a paint thinner, as acrylics in both paste and ink are permanent once dry! To avoid this, make sure to clean your brushes and other tools (especially airbrushes) before the colour dries, using soapy water or, for greater efficiency, the Pebeo Cleaner.

Colorex Inks: How do you avoid fading of the Colorex colours over time?
An anti-UV protection varnish can improve the conservation of artworks.

Colorex Inks: With what other products can Colorex be used?
With gouaches to combine transparent and opaque effects. Indelible India Ink allows for tracing contours and other possibilities. The colouring is done with Colorex.

Colorex Inks : Are Colorex inks indelible?
No, absolutely not, except for the 3 primary colours and the black. Even when applied and dry, the colours can be re-diluted with water. Remember this if you wish to cross or layer colours. If you do not wish to "drag" the colour of the first layer, apply the next layer with a light, steady hand in one swift stroke and without repeats.
You can, however, intentionally work on a wet surface or soak the first layer of colour to create fade effects and mixing: this is the beauty of ink!

Colorex Inks: What are generally referred to as the primary colours?
These are pure colours that are not obtained by mixing other colours. They consist of a particular blue, Cyan blue, a pinkish red called Magenta and a specific yellow. These three colours, called primaries, allow for obtaining, through mixing, all other shades. The primaries of the Colorex range are perfectly chromatically balanced to ensure the best possible consistency of mixtures.

Colorex Inks: Why are the 3 primary colours and the trichromatic black semi-indelible?
This allows for the superimposing of a second layer without "dragging" the first too much. Clean overlays of these transparent inks facilitate the understanding and control of the mixtures of primary colours.

Colorex inks: On which paper can you use Colorex?
Heavyweight papers are recommended. Below 180g, the paper is very easily soaked and has a tendency to warp.

Colorex Inks: How do you create, with a brush, nice flat washes without any marks but with perfect edges?
Apply a large barrier of Drawing Gum all around the area to be filled in. Once the Drawing Gum is dry, apply the flat wash without being worried that it will overflow. Once the colour is dry, peel off the Drawing Gum.

Colorex Inks: For what types of work are Colorex Inks ideal?
Colorex Inks are ideal for comic strips, calligraphy and work with ink or watercolour.

Colorex Inks: With what should Colorex inks be diluted?
Colorex inks are diluted with water only.

Colorex Inks: Should a protective varnish be applied to protect artwork produced with Colorex inks?
Colorex inks are formulated with dyes and, therefore, have a low resistance to light. Artwork created with Colorex should be preserved away from light. As for each artwork, a varnish is always advisable to protect them from dust and UV rays.
