"Mimeos" is not a commonly used word in the English language, thus there are no direct antonyms that correspond to it. Without additional context or information about the intended meaning of the word, it is impossible to provide specific antonyms. However, if we assume that the word is related to "mimeograph", which is an outdated form of duplicating documents, there are several antonyms that can be identified. The opposite of mimeograph could be modern copy and printing technologies, such as digital printers, photocopiers, scanners, and fax machines. Additionally, antonyms for the term could include words like unique or original, as mimeography duplicates identical copies of a document.
