Standard coated fine papers, also known as wood free coated (WFC) papers, are essential in the world of print media. These papers are widely used for various purposes such as advertising materials, books, annual reports, high-quality catalogs, magazines, and even direct mail. They provide a smooth and polished surface that enhances the overall appearance and readability of the printed content.

In recent years, WFC papers have faced competition from other types of papers that cater to different end uses. High bright LWC papers and MWC papers have emerged as strong contenders in less demanding applications. Additionally, art papers have gained popularity in the most demanding end uses due to their superior quality and unique texture.

However, standard coated fine papers continue to dominate the market for offset printing. They are primarily manufactured in sheet form, accounting for approximately 85% to 90% of production. Nevertheless, these papers are also available in reel form to cater to specific printing requirements.

The basis weight of standard coated fine papers ranges from 90 to 170 grams per square meter. This range allows for versatility in choosing the appropriate weight for different printing applications. Moreover, the ISO brightness of these papers varies between 80% and 96%, ensuring vibrant and sharp print results.

To achieve the desired characteristics, WFC papers are primarily composed of chemical pulp, which accounts for more than 90% of the fiber furnish. The remaining composition consists of pigments that contribute to the paper’s opacity and brightness. The total pigment content in these papers ranges from 30% to 45%, depending on the desired outcome.

The production of WFC papers requires a meticulous process to ensure consistent quality and performance. The raw materials undergo various stages, including pulping, refining, coating, drying, and finishing, to transform them into the final product. Each step is carefully executed to achieve the desired smoothness, brightness, and printability.

In conclusion, WFC papers play a crucial role in the print media industry. Their versatility, excellent print quality, and compatibility with offset printing make them a popular choice for advertising materials, books, catalogs, and magazines. While they face competition from other paper types, their consistent performance and wide range of applications ensure their continued demand.
