Risograph printing
Risograph is a brand of digital duplicators manufactured by the Riso Kagaku Corporation, and was released in Japan in 1986. It was originally designed for high-volume photocopying and printing, although it has gained popularity as an alternative graphic printing method. Riso printing is an environmentally friendly and effective printing technique with a unique result, and the process can be described as a hybrid between traditional silk screen printing and modern day photo copying.
Screen printing
Screen printing, sometimes referred to as silk screen printing or serigraphy, is the process of pressing ink through a mesh screen, that has been coated with light sensitive paint and exposed to UV-light to create a stencil. It was popularized as an artistic method by Andy Warhol in the 1960s but is commonly used in a whole range of different industries and fits well for various foundations such as textiles, wood, plastic and of course paper.
Offset Lithography
Lithography is a planographic printing process that makes use of the immiscibility of grease and water. The process was discovered in the late 18th century and became a popular medium among artists during the mid-1800s.
In offset lithography the image is printed on a rubber cylinder that offsets (transfers) the image onto the paper.
