How paper is made
Wood or cotton fibers are beaten until they break down into small particles, and the fibers are diluted with water to make pulp and placed in a reservoir.
Pulp is then metered out in a continuous stream onto a moving wire screen. The moving wire is mechanically shaken side to side to distribute the pulp evenly across the screen and drain water.
The pulp is then transferred to a woven felt blanket and carries paper through a press roll which removes even more water. By varying the woven texture and the location of felts, the finished texture of the paper can be varied.
Next, the paper is run through a “sizing” bath to enhance the working properties of the sheet. Without sizing, the paper would act like a blotter. The amount of sizing is adjusted based on the grade and purpose of the paper.
After the sizing bath, the paper is re-dried. At this point, it will go through different finishing processes depending on the type of paper. A calendaring stack, which is a large stack of rolls that the paper runs though, determines the final smoothness of the sheet.
The paper is then rolled or sheeted. Finally the paper is cut and converted into pads, blocks, books, sheets or rolls. Ready to be used by artists around the world.
