Offset Papers


What is offset printing paper? Offset paper or offset printing paper is a type of thin paper comparable to book paper, used mainly in offset lithography for printing books, magazines, manuals, catalogues, posters, calendars, calendars, pamphlets, letterheads, publication end papers, brochures and envelopes. Offset printing paper is used in sheet-fed and roll-fed printing machines.

In addition to ISO brightness of 80% or more and a font range of 40-300 gsm, offset paper has a large amount of separation to resist excessive moisture saturation when processed in the fountain solution system of an offset press. Offset paper has strong internal bonding and good dimensional stability, high curl resistance, high surface strength and low fibre levels. Offset paper is available in coated and uncoated grades, as well as in smooth, vellum and patterned finishes.


Uncoated paper has a relatively rough surface, which makes it suitable for offset printing due to the good absorption of printing inks and fountain solutions. As a result, it is easy to write on with a pen or pencil and can be stamped for clean printing. For this reason, this paper is often used for office stationery. In printing applications, it can also print high-quality graphics, illustrations and colorful text and is used for a wide variety of products and publications. However, offset printing differs from papers that reproduce high-quality color images, such as art prints.

Lignin is a natural substance found in wood and is removed to prevent yellowing of the treated paper when exposed to sunlight. Softwood and hardwood pulp is often blended to produce smoother offset papers with greater surface strength.

Softwood pulp has longer fibers, which allows for better fiber entanglement and greater strength. Hardwood pulp has shorter fibers, resulting in a thicker paper and a smoother surface.

Offset printing, also known as offset lithography, is one of the most affordable and efficient printing processes in the printing industry for mass production of high-quality, professional-looking books, magazines, calendars, brochures, pamphlets, business forms, business cards, letterheads, catalogues, invitations and stationery, and is the most widely used printing process in the world. This printing method has increased productivity as most operations are now computerized, requiring little to no manual maintenance.
