Pronunciation: [plˈe͡ɪtənz] (IPA) 
Platens is a plural noun used to describe flat surfaces or plates, especially those used in printing presses. Its pronunciation is /ˈpleɪtənz/, where the stress falls on the first syllable. The "pl" sound is pronounced like a "p" followed by an "l" sound, while the "a" is pronounced as it is in "cat" or "hat". The "t" is pronounced as a soft "tuh" sound, followed by an "eh" sound, and the word ends with a short "s" sound.
Platens refer to the flat, usually metal, surfaces that come into contact with another object during pressing or printing. The term is commonly used in the context of machinery and printing processes, particularly in relation to printing presses, typewriters, and industrial equipment.
In printing presses, platens are the flat surfaces between which the paper and the inked type or image are pressed to create the impression on the paper. The platen is typically made of a durable material such as steel or cast iron to ensure even distribution of pressure across the printed material. It is sometimes equipped with heating elements to assist in the drying process of inks or to facilitate thermographic printing techniques.
In typewriters, the platen is the cylindrical rubber-covered roller that moves as the keys are pressed, advancing the paper and allowing characters to be imprinted. The platen's rubber surface provides the necessary friction to allow accurate and consistent typing.
Outside the realm of printing and typing, platens may also be found in machinery where pressing or flattening actions are required. For instance, in industrial settings, large platens are often used in the production of composite materials, such as in the manufacturing of laminates or molded materials.
Overall, platens play a pivotal role in various processes, serving as the interface between the object being worked on and the machinery, ensuring accurate and consistent results.
The word platens is derived from the Latin word platanus, which referred to a type of plane tree. The Latin term was borrowed into the English language through Old French as platen, which initially meant bench or board. Over time, the meaning shifted, and it came to refer specifically to the flat metal or wooden plate used in printing presses. The word platens is the plural form of platen.
