Granthams GT Ltd

A sign shop’s printer does not work alone: production also depends on inks, media, cutting, lamination, and support when a machine stops. Granthams GT has built its business around that full workflow. Based in Preston, the British company has spent about three decades supplying large-format printing, sign-making, and visual-communications technology, including equipment from Mimaki, Roland, HP Latex, Graphtec, Summa, and other industry brands.

The catalog spans solvent, UV, and latex printers; print-and-cut systems; vinyl and flatbed cutters; laminators; inks, printheads, and replacement parts; plus vinyl, films, banners, paper, and other media. It also supplies design and production software. For a small print shop comparing its first machine or a business expanding capacity, sourcing equipment and consumables from one supplier can simplify the decision. The key is matching the setup to the actual work: outdoor signs, window graphics, rigid panels, and indoor print runs call for different configurations.

The company complements sales with manufacturer-trained and certified engineers who install large-format equipment and train users. Its Preston showroom offers private, one-to-one demonstrations by appointment, allowing customers to assess materials, finishes, and workflow with a specific application in mind. Granthams also lists after-sales support, financing, and used or demonstration equipment. The offer is therefore less about buying one printer than about keeping a graphics production line working, from installation through routine supplies.
