Offset Printing (transfer of inked image)
Definition
Offset Printing (transfer of inked image) is a printing technique where ink is transferred from a plate to a rubber blanket and then to the printing surface. This process allows for high-quality images and text to be printed on various materials, such as paper or cardboard. It is primarily a method used in commercial printing, making it a vital tool in the printing industry.
How It’s Used in Printmaking
Offset printing is widely used in printmaking, particularly in commercial projects. The process begins by creating a metal or polymer plate with the desired image. The plate is then covered in ink and pressed against a rubber blanket, which transfers the ink onto the final surface, such as paper. This method relates to lithography, as both involve transferring images from a flat surface. For beginners, offset printing provides a reliable way to produce high-quality prints, while professionals appreciate its efficiency and ability to handle large volumes.
History & Origins
Offset printing originated in the early 20th century, with its first commercial use in 1904 by a printer named Ira W. Rubel in the United States. Initially, it was developed from lithography, which has roots dating back to the late 18th century. Notable artists and printmakers have since adopted this technique, contributing to its evolution and prominence in the art world, particularly in the production of posters and books.
Variations & Related Terms
There are several variations of offset printing, including web offset and sheet-fed offset. Web offset printing uses large rolls of paper, making it suitable for high-volume jobs like newspapers. In contrast, sheet-fed offset uses individual sheets, allowing for greater control over print quality. Both methods differ from digital printing, which uses electronic files directly without the need for plates.
