Litho Cleaning

A clean, grease-free litho plate is essential to plate preparation in lithography. AMETEK Surface Vision’s inspection solutions can spot even small imperfections, enhancing surface quality for accurate printing.

Aluminum from the production line can have surface oil, oxides and other contamination. A cleaning line uses electrochemical processing to provide a clean surface suitable for lithography.

In aluminum-based lithography, the image is made of a polymer coating applied to an aluminum plate. This allows direct printing from the plate, or offset printing by first transferring the image onto a flexible sheet. Both of these methods can be affected by surface defects on the aluminum.

Since even the smallest imperfections on a lithographic plate can affect the printing process, precision surface monitoring is required. Litho cleaning lines can be fitted with automated systems that will detect and classify defects without impairing process speeds.
