Offseteihin

Offseteihin is a Finnish term that translates to "offsets" in English. In the context of printing, offsets refer to a method of printing that uses a rubber blanket to transfer an inked image from a plate to a printing surface. This indirect printing process is widely used for high-quality, high-volume printing jobs, such as newspapers, magazines, and brochures.

The offset printing process begins with the creation of a printing plate for each color to be printed. These plates are typically made of aluminum and are coated with a light-sensitive material. The desired image is exposed onto the plate, which is then developed to create a raised image area that will hold ink. The plate is then mounted onto a printing press, where it is dampened with water to prevent ink from adhering to the non-image areas.

Ink is applied to the plate, adhering only to the raised image areas. The inked image is then transferred (or offset) onto a rubber blanket, which in turn transfers the image onto the printing surface, such as paper. This indirect transfer process allows for high-quality printing with fine details and consistent color reproduction.

Offset printing is known for its efficiency and cost-effectiveness, especially for large print runs. The initial setup costs can be high due to the need for creating printing plates and calibrating the press, but the per-unit cost decreases significantly as the quantity increases. This makes offset printing an ideal choice for projects requiring large quantities of printed materials.

In Finland, offset printing has been a staple of the printing industry for many years, with numerous companies specializing in this method. The term "offseteihin" is commonly used in Finnish printing circles to refer to the offset printing process and its related techniques.
