Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a printing method for composite printing of two types of images on the same frame.

[Conventional technology]

Recently, as a postcard, an image of a person or the like is printed on photographic paper as the main image, and it is placed next to it.
Synthetic print photographs printed with illustration images such as greetings are widely used. Such a composite photograph is formed by arranging a negative film for a main image and a lith film for an illustration image in front and rear at a predetermined interval, and simultaneously printing these images on a photographic printing paper for transfer.

Conventionally, when the image film is exchanged, the front and rear films are converted by shifting the timing by the interval of the exposure station so that the printing paper is not wasted.

[Problems to be Solved by the Invention]

In the above-mentioned conventional method, the operator replaces the film in consideration of the interval between the two exposure stations. Therefore, when the print size is changed, the replacement timing changes, which is likely to cause a mistake. There was a problem.

[Object of the Invention]

The present invention has been made in view of the above points, and an object of the present invention is to provide a photographic synthetic printing method capable of avoiding an operation error associated with film exchange without causing waste of the photosensitive material.

Another object of the present invention is to easily cope with a case where the print size is changed.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a looper section between the first and second exposure stations to adjust the distance between the exposure stations on the light-sensitive material according to the print size, and to adjust the distance between the two images. The first step of printing the first image and the second image by the two exposure stations until the set number of prints of the first image is reached, and the exposure step is performed when the set number of prints of the first image is reached. The second step of printing only the second image by the number of frames corresponding to the interval between the first and second exposure stations on the material, and when processing the next matter, after finishing the second step , The photosensitive material is fed back to position the front end of the unexposed portion at the first exposure station, and the third step of exchanging the image of each exposure station for the next one and the third step are completed. And a fourth step of printing only the first image by the number of frames corresponding to the interval between the first and second exposure stations on the photosensitive material, and after finishing the fourth step, the first step is performed. Return to the process,
Hereinafter, when processing the next case, each step is repeated in order, and when the next case is not processed, the second step is processed and terminated.

[Action]

Since the photosensitive material is sent back at the end of the previous print,
Since the light-sensitive material can be effectively used and two kinds of films are exchanged at the same time, there is no mistake in the timing of film exchange. Further, the print size can be easily changed by changing the length of the photosensitive material between the first and second exposure stations according to the print size by the looper unit.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

First, the overall configuration of the photosynthesis printing apparatus according to this embodiment will be briefly described. In FIG. 2, a long photographic printing paper 10 is pulled out from a supply reel 12, exposed, and then wound around a winding reel 14. The photographic paper 10 is transported by four pairs of transport rollers 2 driven by motors 16 and 18.
The printing paper 10 is accurately sent frame by frame. Further, tension rollers 22 and 24 are arranged in order to prevent an excessive tension from acting on the photographic printing paper 10 at the initial stage of conveyance.

Further, a dancer roller 30 is provided between the exposure stations 26 and 28 which expose the letter (X) of the illustration lith film 40 and the image (Y) of the image negative film 41, respectively. The distance between the exposure stations can be adjusted by pulling downward. That is, the dancer roller 30 adjusts the distance between the two exposure stations according to the print size,
In the present embodiment, the interval is always set to three print frames.

On the other hand, the printing light emitted from the light sources 32 and 34 is diffused in the diffusion boxes 36 and 38, respectively, and then set to a film carrier (not shown) for illustration image lith film.
40, and the negative film 41 for main image is irradiated. And
The light transmitted through the films 40 and 41 passes through the projection lenses 42 and 43 and enters the photographic printing paper 10.

Behind the optical axes of the projection lenses 42, 43, the drive devices 44, 46
Shutters 48 and 50 that are driven to open and close by are respectively arranged so that the printing light is made incident on the photographic printing paper 10 by opening for a time corresponding to the required exposure amount.

Further, paper masks 52 and 54 are provided between the shutters 48 and 50 and the printing paper 10, respectively, and the exposure range is adjusted by these.

Next, a printing method by the printing apparatus configured as described above will be described.

First, the target illustration lith film 40 and the image negative film 41 are set on the respective optical paths. Next, from the input device (not shown), print the number of sheets (for example, 100 sheets).
And print size (L, 2L, etc.). When the print size is determined, the projection lenses 42 and 43 are selected correspondingly and set on the printing optical path. Further, the exposure range of the paper masks 52 and 54 is adjusted according to the print size and the ratio of the main image and the illustration image.

On the other hand, the distance between the exposure stations of the printing paper 10 is adjusted by the dancer roller 30 according to the set print size. That is, when the print size is large, the photographic printing paper 10 is pulled downward, and when the print size is small, the downward tension is relaxed, and the interval between the exposure stations is set to 3.
Keep on top.

Next, the light sources 32 and 34 are turned on. These light sources 3
The printing light emitted from each of the light sources 2, 34 is diffused by the diffusion boxes 36, 38, and then enters each of the films 40, 41. afterwards,
Open and close the shutters 48, 50 according to the printing timing,
A character (X) and an image (Y) are printed on the photographic printing paper 10 at the same time.

By repeating such a printing operation, as shown in FIG. 3 (1), the letter (X) of the lith film 40 arranged on the front side
When the number of prints in (1) reaches the set number (100), with printing at the exposure station 26 stopped,
As shown in (4), the negative film is exposed at the exposure station 28.
Print only 41 images (Y) for 3 steps (98Y to 100Y).

Next, when the printing of the image 100Y is completed, the illustration film lith film 40 and the main image negative film 41 are replaced at the same time with the next item, and as shown in (5),
Send back 26 frames by 2 frames and write the letter (X) at the end of the unexposed part
Return to the exposure position of.

Then, as in (5) to (7), new characters 1X to 3X are printed at the exposure station 26 with the exposure station 28 waiting this time. After that, as shown in (8), the character (X) and the image (Y) are simultaneously printed as usual.

〔The invention's effect〕

As described above, according to the present invention, the looper portion is provided between the first and second exposure stations, and the interval between the exposure stations on the photosensitive material is adjusted according to the print size. However, you can easily deal with it, and you can easily create composite print pictures of different sizes.

Also, until the number of prints of the first image reaches the set number,
The first image and the second image are printed by the two exposure stations, and when the number of prints of the first image reaches the set number, only the number of frames corresponding to the interval between the first and second exposure stations on the photosensitive material. When printing only the second image and processing the next item, the photosensitive material is fed back to position the front end of the unexposed portion at the first exposure station, and the image of each exposure station is transferred to the next item. And the first image is printed by the number of frames corresponding to the interval between the first and second exposure stations on the photosensitive material.
Even if there is a size change such as a change to the 2L size, no blank space is generated when changing the print content, and the waste of the photosensitive material can be eliminated.

When processing the next matter, the photosensitive material is fed back to position the tip of the unexposed portion at the first exposure station, and the image of each exposure station is exchanged for the next matter. The images can be exchanged at the same timing, and operation mistakes such as forgetting to exchange one image can be eliminated. Moreover, since the images are exchanged after they are fed backward, unlike the conventional case where the images are exchanged after printing only one side, the timing of the image exchange will not be wrong, and the two images can be exchanged reliably. You can
