Medium Copperplate Oil - Cranfield - 1l

Medium Copperplate Oil by Cranfield is a medium-viscosity oil designed for thinning all oil-based printing inks and etching inks.

It reduces ink density, improves flow, and facilitates smooth and even application during printing. It is particularly recommended for printmaking techniques that require a slightly lighter but still controlled ink consistency.

The history of Cranfield dates back to the late 1920s, when George Craine Senior—the grandfather of the current managing director—began working at Johnson & Cumbers in London’s Sugarhouse Lane, then a major centre for ink and paint production. There, he developed his craft in an era when the needs of artists came first, rather than mass production. This philosophy, rooted in craftsmanship and quality, became the foundation of the family business.

In 1976, George Craine Junior, committed to traditional methods and their value for artists, founded the Cranfield Group, using classical processes to produce high-quality dry pigment inks. The brand quickly gained recognition within the art community for its authenticity and craftsmanship. In 2009, Spectrum Paints joined the family, helping preserve the heritage of traditional British paintmaking and maintaining rare machinery and techniques that remain at the heart of the company today.
