The document describes a portable ink-removal device for cleaning ink rolls. It consists of a scraper blade attached to a rockshaft that can be manually applied to either side of a rotating ink roll. The device can accommodate ink rolls rotating in either direction without modification. It is designed to overcome limitations of prior hand cleaning methods and permanent scraper attachments for ink rolls. The device aims to provide a simple, durable, and low-cost portable solution for ink roll cleaning.
