History of Triangle
Triangle printing was founded on Triangle lane in Wheaton, Maryland in 1974 by Al Parker. The company specialized in custom tabs and dividers for looseleaf binders. A small operation with less than 5 employees capitalized on the needs of other printers to fulfill orders for completed manuals and documentation books that required tabbed dividers.
At the time, there were very limited printing plants that could mass produce laminated tabs and dividers. Hence, Triangle soon became the printer's printer for specialty looseleaf products and custom laminated tabs in the Washington, DC metropolitan area.
Today at Triangle
Since then, Triangle has expanded its capabilities to include screen printing, offset printing, die cutting and assembling of vinyl binders for just about any custom application you can think of.
Triangle still specializes in the manufacture of custom imprinted and laminated Tabs as well as custom ring binders (also called looseleaf or loose-leaf ring binders), specialty binders, foil stamping and die cutting, four color process printing, decals and a large range of related vinyl and paper products.
