The newspaper publisher, whose 16 titles include the John O'Groat Journal, Northern Scot and Inverness Courier, will have a fifth four-high tower installed this spring.

The five four-high tower configuration will allow one of the towers to run either four mono webs as required or one colour web.

Scottish Provincial Press managing director Roy Fox called the investment a response to "demand for greater colour and pagination by our advertisers" and a move to "deliver exactly what our customers demand".

The publisher commissioned the original Goss press in 1998 with a specification for two four-high towers, each configured for four-over-one colour, and three mono units.

Subsequent upgrades have included a four-over-four colour with an additional four-high, full-colour tower in 2004.

Fox said that "very quickly it became apparent we would require additional capacity" and since the original installation, the newspaper site has become a reference site to demonstrate the Universal technology.
