Artists for many years have appreciated the qualities of Daler Rowney the Langton. The paper is colour stable, mould made & acid free. The best watercolour papers are acid free to prevent the deterioration of paint & to preserve the integrity of the paper over time. The paper has a 'NOT' surface (also known as cold pressed) which is in between the roughest & smoothest texture of papers. This makes it a very versatile paper popular for watercolour & linewash work. It can also be used for pastels, inks, designers' gouache & acrylics.
