Film coated offset (FCO) paper is a relatively new paper grade that has gained popularity in the printing industry. This type of paper utilizes film coating technology, which was introduced as a coating method for mechanical pulp-dominated papers in the mid-1990s in Europe. Over time, film coaters have been incorporated into the latest lightweight coated (LWC) paper production lines as well.

FCO paper is primarily used in special interest magazines and catalogs, where it proves to be an excellent choice for heat-set web offset printing. It is designed to compete with LWCO grades, offering comparable quality and performance.

Currently, FCO paper is produced in a basis weight range of 45 to 65 g/m2. Despite its lightweight, this grade offers a high bulk, meaning it has a thick and substantial feel. This is particularly advantageous in the printing industry, as it adds a sense of quality to the final product.

In addition to its high bulk, FCO paper also boasts good surface strength with minimal fiber roughening. This is essential for maintaining the integrity of the printed image during the printing process and subsequent handling. The surface of FCO paper also exhibits sufficient gloss, although not as high as that achieved with LWCO paper.

One notable difference between FCO paper and other coated papers is the surface roughness. Due to its unique surface structure, FCO paper tends to have a slightly rougher surface compared to blade-coated paper. While this may be a drawback for some applications that require a smoother finish, it is often not a significant concern for the target applications of FCO paper.

In terms of overall paper quality, FCO paper is now very close to LWCO paper. It offers comparable performance and printability, making it a viable alternative for printers and publishers. Its unique characteristics, such as high bulk and good surface strength, make it an attractive choice for those looking to achieve a high-quality printed product.

As the demand for specialized magazines and catalogs continues to grow, FCO paper is likely to gain further popularity in the printing industry. With its excellent heat-set web offset printing capabilities and competitive qualities, it is poised to become a staple in the production of high-quality printed materials.
