【Reproduction】 , 【duplicate】 ,  【copy】 ,  【carbon copy】 ,  【facsimile】 ,  【replica】 ,  【transcript】  are comparable when they mean one thing which closely or essentially resembles something that has already been made, produced, or written.

【Reproduction】  may imply identity in material or substance, in size, and in quality, or it may imply differences, provided that the imitation gives a fairly true likeness of the original; thus, a  【reproduction】  of an Elizabethan theater may be on a very small scale; a  【reproduction】 of a Sheraton chair may be in cherry rather than in the mahogany of the original.

A  【duplicate】 is a double of something else; the word may be used of something that exactly corresponds to or is the counterpart of any object whatsoever.

A  【copy】  is a 【reproduction】 of something else, often without the exact correspondence which belongs to a 【duplicate】 ; however 【copy】 , rather than  【duplicate】 (which logically implies that there is but a single 【reproduction】 ), is applicable to any one of a number of things printed from the same type format, struck off from the same die, or made in the same mold.

【Carbon copy】  stresses the idea of exactness found in  【duplicate】 .

A  【facsimile】 is a close but usually not exact 【reproduction】 ; the term may imply differences (as in scale) but it implies as close an imitating in details and material as possible or feasible.

【Replica】  applies specifically to an exact 【reproduction】 of a statue, a painting, or a building made by or under the direction of the same artist, architect, or artisan; thus, one does not speak accurately of a modern  【replica】  of the Winged Victory, but of a modern  【reproduction】 ; one may speak of the confusing tendency of some Renaissance artists to make replicas of their paintings. However the word is often used merely to emphasize very close likeness.

【Transcript】 applies only to a written, typed, or printed 【copy】 made directly from an original or from shorthand notes.
