Formation is a crucial part of papermaking that refers to how paper fibers are arranged during the manufacturing process. It's like laying down a puzzle where all the pieces (fibers) need to be evenly distributed to create smooth, consistent paper. Good formation means the paper will have uniform thickness, strength, and appearance. Think of it like making a perfect pancake - if the batter isn't spread evenly, you get thick and thin spots. In paper industry terms, poor formation can lead to quality issues in the final product.
