Which type of board is characterized by heavy weight?

Illustration board is known for its heavy weight and sturdiness, making it an ideal surface for various mediums in fine art and illustration. This type of board typically has a rigid structure that supports detailed work and can withstand multiple applications of paint, inks, and other materials. Its thickness allows artists to work confidently without the fear of warping or damaging the surface, making it especially suitable for professional practices where a polished finish is desired.

In contrast, Bristol board is also heavy but is typically smoother and is often used for detailed line work rather than the more textured applications seen with illustration board. Sketch paper is designed primarily for quick, informal drawings and is usually lightweight, allowing for easy portability. Newsprint paper, while useful for practice and studies, is very lightweight and may easily tear, making it unsuitable for heavy applications. Each type of paper or board has its specific intended use, which is why understanding their characteristics is crucial for selecting the right one for a project.
