Wood pulp is typically used to make modern paper. A thin liquid known as "paper pulp" is created by pulverizing wood and combining it with water and other chemicals. It is possible to bleach paper pulp to make it whiter and to add dyes to create colored paper. Paper sheets are created by squeezing this pulp. Paper is frequently printed on before being cut into sheets. Newsprint paper (newspaper) is delivered in a sizable roll and is printed as a single continuous sheet. Later, it is sliced with a guillotine blade driven by a machine. Packing for distribution is done last, then folding. Clay can sometimes be added to paper, and it can also be "milled" to make it heavier and glossier.
