Gouache and acrylic are appropriately considered as wet techniques. Nevertheless due to the high content of gum or artificial binders, these paints can be used on almost all materials which accept water as long as they are thick enough and sufficiently sized to handle the humidity.
The choice of the paper’s colour depends on the opacity of the colour and the requirement for luminosity and contrast. These factors vary depending on the shade of the paper (from black to white and including the whole spectrum of colours.)
If the colours are transparent (watercolour, ink, certain acrylics) white paper is the most adapted (the desired luminosity will depend on the whiteness.)
If the colours are opaque (gouache, some acrylics) and therefore covering, all shades can be used.
There are two vegetable fibre pulps (cotton and cellulose). Their conservation qualities and their costs are relatively different.
The weight of the paper has a direct impact on the price but above all its ability to conserve its flat surface.
The grain of the paper (semi-gloss, fine, rough grain) depends on the degree of precision desired.)
Selection from the many types of paper (books, pads, sheets and rolls) depends on its use whether it is for carrying around, travelling, studio work, or preparatory work for large scale works.
In terms of the pads, bound 4 sides blocks are available which allow very wet application while guaranteeing a perfectly flat work once dry (ideal for medium and large format outdoor work.)
Furthermore, above and beyond these criteria, CLAIREFONTAINE has developed a quality of paper available only in white and 360g which is well adapted to all wet techniques. It facilitates the work while encouraging colour adhesion and noticeably increases the amount of reworking time.
Paper destined for oils is unique in its oil-resistance which protects its fibres from solvent attacks. Because of this the choices are reduced to the packaging. Nevertheless it is important to understand its specifics:
