An Answer print (or first trial print) is, literally, the first copy printed from a cut negative; it is generally thrown away (or at least considered to be of inferior quality) because it needs to be further corrected in the grading to satisfy the requirements of the producer. Answer prints in colour, especially those produced before the use of Video Colour Analysers in the laboratories, could be very different from the quality of the final copy as they would be the first trial-and-error print made. The only way of identifying answer prints, if there isn't anything written on the can or at the end of the film, is to evaluate the quality, if possible by comparing it to another copy. However, this may not always be helpful. Technicolor release prints could differ remarkably from each other, as the early systems were not very reproducible. Some laboratories made Answer Prints that had no sound making identification easier.
