Abstract
A photographic printer has a first set of negholds for use with first-run production printing, and a second set of negholds for use with reprint production printing from film segments attached to an elongated paper tab. The first set of negholds includes one neghold for each of the commonly used sizes of photographic film, such as 110, 126 and 135. Similarly, the second set of negholds includes a neghold for each of these same common film sizes. Circuitry associated with the neghold indicate to the printer control whether a first-run neghold or a reprint neghold is being used. The photographic printer has stored a first set of calibration values for use with the first set of negholds and a second set of calibration values for use with the second set of negholds. Based upon the indication from the circuitry associated with the negholds, the photographic printer automatically selects which set of calibration values are to be used. Selection of the particular calibration values from either the first or second set of values is determined by the color balance setup.
