Abstract
A composition for cleaning a print roller such as an anilox roller includes a soap or cleansing agent having a plurality of grit particles, an organic acid, an emulsifier, and water. A solvent is mixed with the cleansing agent to complete the composition. A method of utilizing the cleaning composition includes providing the composition, selecting an applicator, and mixing the composition. The method then includes wiping the composition repeatedly over the print roller using the applicator until the surface and plurality of cells in the roller surface are substantially free of dried ink and other contaminants.
