A platen (or platten) is typically a flat metal (or earlier, wooden) plate pressed against a medium (such as paper) to cause an impression in letterpress printing.he platen sits between two steel rolls which deliver the moving force to the sanding belt. Sanding heads with a platen are used on finish sanding with papers of finer grits, when the coarser ones are typically used with contact drum type sanding heads. Stock is fed into and out of the machine on a conveyor belt.
A macron (/ËmÃ¦krÉn, ËmeÉª-/) is a diacritical mark, a straight bar (Â¯) placed above a letter, usually a vowel. Its name derives from the Greek Î¼Î±ÎºÏÏÎ½ (makrÃ³n), meaning long, and was originally used to mark long or heavy syllables in Greco-Roman metrics. It now more often marks a long vowel. In the International Phonetic Alphabet, the macron is used to indicate a mid-tone; the sign for a long vowel is instead a modified triangular colon â¨Ëâ©. The opposite is the breve â¨Ëâ©, which marks a short or light syllable or a short vowel.
