The exposure information for determining the exposure condition of the above may be changed so as to approach the ideal scanning data of the sepia print, and the exposure information of the new sepia print may be stored in the exposure control means 1. With this configuration, even the difference in the development conditions can be fed back, so that it is possible to obtain sepia prints of even better quality and constant quality.

Further, needless to say, the printer and the processor may be provided separately.

Further, without storing the exposure information in advance in the exposure control means, the exposure information itself indicating the exposure conditions for the sepia print is recorded as an optical code or magnetic information on the sepia print film. An exposure information reading means for reading exposure information recorded on the film may be provided in the printer, and the exposure unit may sequentially perform exposure under exposure conditions based on the exposure information read by the exposure information reading means. .

It is possible to automatically distinguish between color negative film and developed monotone negative film, and even if the person who handles the printer is a part or part-time job, the developed color negative film is used as a photographic original to perform monotone exposure, The mistake of doing the reverse is reduced.

Further, monotone prints using a single film as a photo original may be all monotone prints of the same color, or a monotone print color type may be designated for each image frame, and a different color type may be designated for each image frame. May be obtained.

(Embodiment 3) Another embodiment of the monotone print system and the photographic printing apparatus according to the present invention will be described with reference to FIGS. FIG. 6 is a schematic explanatory diagram of the monotone print system according to the present embodiment.

In the present monotone print system, the customer selects a desired monotone print color type from various colors recorded in the color sample 18, and converts the monotone print of the color into the printer processor 300 according to the present embodiment.
It is created in C. (A specific example of the color type will be described later.) The customer looks at the color sample 18 placed at a photo shop and the like,
Select the desired color. Color sample 18 contains color samples,
The color name (not shown) and a code number indicating the color type are recorded in association with each other. The color sample 18 is preferably recorded such that similar colors are close to each other based on the hue.

It can be said that the barcode reader 9 is the exposure information input unit in the present invention.

The printer processor 300C can perform not only monotone printing but also ordinary color printing. Here, a case is considered in which a normal developed color negative film and a developed monotone negative film are treated as a photographic original while being mixed. When the developed film 16C is set on the exposure unit 3C, the code reading unit 2C reads the optical code recorded on the sticker attached to the developed film 16C. Note that a bar code reader or the like can be used as the code reading unit 2C.

As a method of recording the color type of the monotone print on the monotone negative film, the monotone negative film has a magnetic layer, and the fact that the monotone negative film is a monotone negative film and the color type of the monotone print are magnetically recorded on the magnetic layer. When the information is recorded, a magnetic information reading unit such as a magnetic reading head can be used as the color type reading unit.

In the case where the developed film 16C is a developed monotone negative film, the code reading means 2C records the fact that the film is a monotone negative film recorded on the color type sticker and the color type of the monotone print (indigo). ) Is read, and a signal to the effect that the film as the photographic original is a monotone negative film and a designation of the color type (indigo) of the monotone print is transmitted to the exposure control means 1C.

Exposure control means 1C reads code reading means 2C
When a signal indicating that monotone printing of indigo (No. 5) is to be performed is received from, the exposure information for obtaining the monotone printing of indigo is read out from the exposure information for monotone printing input in advance. Based on the read exposure information for the monotone print of the indigo, the exposure conditions such as the light emission amount of the light source of the exposure unit 3C, the insertion timing of the Y, M, and C filters, and the insertion timing of the shutter 6C are controlled. Negative film 4C
Is used as a photo original to perform indigo monotone printing on color paper 5C.

When a plurality of types of monotone negative films exist, not only exposure information is stored for each color type, but also exposure information corresponding to each combination of film type and color type is sent to the exposure control means. (For example, exposure information when the color type is Indigo for a monotone negative film with a sensitivity of 400 from K Company, exposure information when the color type is Indigo for a monotone negative film with a sensitivity of 100 from L Company, etc.) Then, the DX code reading means provided in the printer 100B reads the DX code indicating the type of the film, identifies the type of the film, and outputs the exposure information corresponding to the combination of the film type and the color type to the exposure control unit. And exposure may be performed.

On the other hand, when the developed film 16C is a normal color negative film, the code reading means 2C
Reads an optical code recorded on a sticker indicating that the film is a normal color negative film, and sends a signal indicating that normal printing is to be performed to the exposure controller 1C.
Send to. In this case, the exposure control device 1C controls the color paper 5 under the exposure conditions when performing a normal color print.
The exposure device 3C and the shutter 6C are controlled so that C is exposed.
