We have all kinds of rollers that are used in offset printing presses including ink rollers, transfer rollers, and dampening rollers. Offset printing rollers are typically made from rubber or polyurethane. These materials have a high coefficient of friction, good elasticity, and excellent ink transfer properties. The best picture for offset printing rollers would be one that is high resolution, with clear, sharp edges and consistent tone and color throughout the image. It’s important that the image is properly prepared for printing, with the correct color profile and resolution, to ensure the best print quality.
