Herein is a modification of a conventional rotary screen printer wherein steel slugs are positioned inside a hollow squeegee rod to line up with heavy print areas. When more magnetic force is applied to the steel slugs, less ink is deposited since the screen is held tighter against a nonporous substrate.
