The Gutenberg press worked by a metal moveable type being pressed down onto paper using oil-based inks. This method allowed for uniform characters across the entire book. This is an example of relief printing.
Moveable type is the system of printing that uses moveable components to reproduce the same elements of a document consistently.
Porus printing, also known as screen or ink printing, ink is brushed onto a screen which is on some object, usually paper but it can also be metals, glass, or a textile. Intaglio printing, also called gravue printing, works by etching images below the surface and filling the engraving with ink. Excess ink is then removed before transferring the remaining ink to it’s final medium. Lithography uses stones and metal plates that are kept wet with water. The ink is placed on the wet plates and then special paper is placed on top of the stone before being run through the press. After it is run through the press, the paper is taken off and the stone or metal is left with the image. Offset lithography uses digitally made metal plates that are inked. The ink is then transferred to a rubber cylinder and then finally to paper.
One major improvement on Guttenberg’s orginal printing press is the speed of impressions. By 1940, printing presses could do over 3500 impressions/ hour. Today’s printing presses follow the same basic principles, but are much more automated.

CYMK is a four-color process method of printing that is based on the subtraction principle that states if all colors are removed, only white remains. It works by combining cyan, yellow, magenta, and black to create the desired colors. These colors are layered onto one another, usually in that order.
