Trükisilinder

Trükisilinder is a term originating from Estonian that translates to "printing cylinder" or "lithographic cylinder." It refers to a critical component in various printing processes, particularly in offset lithography. The trükisilinder is typically a metal cylinder that is etched or engraved with the image or text to be printed. This image is then transferred to a rubber blanket cylinder, which in turn prints onto the paper or other substrate.

In lithography, the image on the trükisilinder is created by areas that are either hydrophilic (water-attracting) or oleophilic (ink-attracting). Ink adheres to the oleophilic areas, while water adheres to the hydrophilic areas, effectively separating the ink from the non-image areas. The precise engineering and surface treatment of the trükisilinder are crucial for achieving high-quality, sharp, and consistent printed results. Different types of printing presses utilize trükisilindrid with varying specifications depending on the printing method and the desired output. The production of these cylinders involves specialized techniques to ensure accuracy and durability.
