Sizing is used during paper manufacture to reduce the paper's tendency when dry to absorb liquid, with the goal of allowing inks and paints to remain on the surface of the paper and to dry there, rather than be absorbed into the paper. This provides a more consistent, economical, and precise printing, painting, and writing surface.
What is sizing in papermaking?
Sizing or size is a substance that is applied to, or incorporated into, other materials—especially papers and textiles—to act as a protective filler or glaze. Sizing is used in papermaking and textile manufacturing to change the absorption and wear characteristics of those materials.
What are the benefits of sizing paper?
Sizing paper will reduce or eliminate this bleeding and feathering by enveloping the cellulose fibers. As an added benefit, sizing protects the fibers from breakdown due to oxidation. In addition, since other commonly used fillers can inhibit bonding between fibers thereby weakening the sheet, sizing adds adhesive qualities and strength to paper.

Internal sizing chemicals used in papermaking at the wet end are alkyl succinic anhydride (ASA), alkyl ketene dimer (AKD) and rosin. By making the paper web more hydrophobic, the sizing agents influence dewatering and retention of fillers and fibers in the paper sheet. Next to paper quality, internal sizing agents' main effect is on runability of the paper machine.
What is surface sizing?
Surface sizing solutions consist of mainly modified starches and sometimes other hydrocolloids, such as gelatine, or surface sizing agents such as ac rylic co-polymers. Surface sizing agents are amphiphilic molecules, having both hydrophilic (water-loving) and hydrophobic (water-repelling) ends. The sizing agent adheres to substrate fibers and forms a film, with the hydrophilic tail facing the fiber and the hydrophobic tail facing outwards, resulting in a smooth finish that tends to be water-repellent. Sizing improves the surface strength, printability, and water resistance of the paper or material to which it is applied. In the sizing solution, optical brightening agents (OBA) may also be added to improve the opacity and whiteness of the paper or material surface.

In any case, it’s all about the sizing. Without sizing, paper tends to soak up anything liquid. For instance, ink will bleed or feather, immediately soaking into the paper. See above for an example of ink on paper towel.
Overview
Papermaking
Sizing is used during paper manufacture to reduce the paper's tendency when dry to absorb liquid, with the goal of allowing inks and paints to remain on the surface of the paper and to dry there, rather than be absorbed into the paper. This provides a more consistent, economical, and precise printing, painting, and writing surface. This is achieved by curbing the paper fibers' tendency to absorb liquids by capillary action. In addition, sizing affects abrasiveness, creasability, finish, prin…
Gilding
Sizing is a term used for any substance which is applied to a surface before gilding in order to ensure adhesion of the thin gold leaf to the substrate. Egg whites have often been used as sizing; the Ancient Egyptians sometimes used blood. Other commonly used traditional materials for gold leaf sizing are rabbit-skin glue diluted and heated in water (water gilding), and boiled linseed oil (oil gilding); modern materials include polyvinyl acetate.
Textile warp sizing
Textile warp sizing, also known as tape sizing, of warp yarn is essential to reduce breakage of the yarn and thus production stops on the weaving machine. On the weaving machine, the warp yarns are subjected to several types of actions i.e. cyclic strain, flexing, abrasion at various loom parts, and inter yarn friction.
With sizing, the strength—abrasion resistance—of the yarn will improve and th…
