Kohopainatuksessa

Kohopainatuksessa, also known as relief printing, is a family of printing techniques where the image is created by applying pressure to a surface with an inked, raised area. The parts of the printing plate that will transfer ink are raised, while the areas that will not transfer ink are recessed. This contrasts with intaglio printing, where the ink is held in recessed areas.

Historically, the earliest form of printing was relief printing, with woodblock printing being a prominent example dating back to ancient China. In this method, an image is carved into a wooden block, leaving the desired printing areas raised. Ink is then applied to these raised areas, and paper is pressed onto the block to transfer the image. Other common relief printing techniques include linocut, where the image is carved into linoleum, and rubber stamp printing, which uses a rubber plate mounted on a handle.

The process typically involves preparing a printing plate, inking it, and then transferring the ink to a substrate, usually paper or fabric, through pressure. The raised surface of the plate holds the ink, and when pressed against the substrate, the ink is transferred to create the printed image. The texture and depth of the raised areas can influence the final printed appearance, often resulting in a characteristic tactile quality. Kohopainatuksessa is still used today for artistic prints, book illustrations, and decorative purposes.
