Papers and boards are formed from wood pulp, which comes from trees. This squishy wood pulp is rolled out into thin sheets in paper mill factories to form the papers and boards that we use.
|Paper||Physical properties||Working properties|
|Bleed proof paper||White, can be textured, thin||Coated to stop colour seeping, ink stays bright on the surface|
|Cartridge paper||Thick, textured, rough||Expensive and opaque, used for ink and watercolour|
|Grid paper||White paper printed with a variety of grids, eg isometric, graph etc||Lines are usually blue but can be darker to trace through|
|Layout paper||Smooth finish, off-white colour, translucent (see-through)||Takes most media well|
|Tracing paper||Translucent (see-through), smooth||Shiny, takes pencil well|
Board thickness is measured in microns or grams per square metre (gsm) - the thinner the card the lower the microns or gsm.
|Board||Physical properties||Working properties|
|Corrugated card||Paper bonded to the outside||Corrugations make it strong, protective and insulating; used in packaging|
|Duplex board||Two layers of card bonded together||Stiff, lightweight and printable for packaging|
|Foil-lined board||White card with foil backing||Stiff and oil resistant, foil backing reflects heat, used for food containers|
|Foam core board||Smooth surface, laminated with white board||Thick and rigid, available in a variety of thicknesses, prone to creasing and cracking, used for models and mounting photographs|
|Inkjet card||Bright white and smooth on both sides||Deep colours as the photographic ink sits on the surface|
|Solid white board||Smooth on both sides||Stiff, can be cut or scored|
