GLOSSARY FINE ART PAPER The following features are characteristic of quality papers, and will assist in paper selection. HOT PRESS Used for portraits. Discreet and reserved, it focuses attention on the subject of the work, emphasizing the drawing. However with such a subtle medium a certain degree of technical mastery is essential. LAID PAPERS Papers with a subtle line texture created during the production process. Laid papers provide a surface that is ideal for charcoal, pastels, and drawing. LIGNIN Lignin is an organic substance that acts as a binder for cellulose fibers in wood and certain plants, adding strength and stiffness to the cell walls. Lignin is undesirable in the production of fine, permanent papers because it reacts with light, heat and humidity to produce acids that cause deterioration of the paper. Quality Canson papers are lignin free. MICRO-PERFORATION Canson wire bound pads feature tiny perforations that provide a clean edge when the sheets are torn from the pad. pH Paper acidity is measured in terms of pH. Any paper with a pH level above 7 is considered alkaline, and below 7 is considered acidic. With time, acids will damage paper through oxidation, causing brown stains and reduced strength. Acid-free Canson papers contain pH levels above 7, ensuring longevity. PAPER PRODUCTION There are three methods of producing paper. Handmade paper is made by skilled craftspeople, typically of 100% cotton. It features irregular texture, and is usually more expensive than machine- made papers. Mould-made papers are produced on cylinder mould machines. Their random fiber distribution makes them durable and resistant to distortion. Fourdrinier machine-made papers are more economical and consistent in formation, and typically are smoother papers. PRINTER COMPATIBILITY With improved technology, it is now possible to achieve great results on a wider variety of papers with laser and ink-jet printers, including textured and heavyweight papers. Paper specifications can generally be found in the printer Users manual. PULP COLORING Canson papers are colored in the pulp to be bleed- and fade-resistant. PULP COMPOSITION Paper is made from cellulose – the fibers that are the main constituent of all plant life. Canson papers are made from high alpha cellulose content virgin pulp – either purified wood or cotton. Alpha cellulose fibers are the best choice for permanence because their length and structure makes them the strongest and most stable type of cellulose. ROLLER-MARKED PAPER The imprint left by a roller run along the edge of a sheet manufactured on a Fourdrinier paper machine. ROUGH GRAIN An effect close to that of handmade paper. This rough grain paper helps to achieve valuable effects of texture. SIZING Sizing is the substance added to paper that allows the paper to accept ink, resist water, and have greater tear strength. For longevity and durability, the sizing must be neutral or alkaline. Canson uses only neutral or alkaline sizing in the production of its papers. SMOOTH PAPER Paper with a smooth, satin-like surface for work involving a great deal of details done in pencil, with scope for adding color using marker pens. This grain is ideal for graphic and technical creative work. TRUE SIZE Only Canson wire bound pads feature true size sheets, enabling consumers to get full use of the paper dimensions stated on the pad cover. VELLUM A paper without any ribbing, so smooth it recalls the finest parchment, making an ideal medium for drawing. WATERMARKS Watermarks are created during the production process and leave a permanent impression in the sheet, which is visible when the paper is held up to light. Watermarks can be registered (appearing in the same place on every sheet), or random (varying in their location on the sheet). 11
