Abstract

PURPOSE:To evade misoperation arising when film is replaced by reversely feeding a photosensitive material upon the completion of previous printing and simultaneously replacing two types of films. CONSTITUTION:When the number of character prints of a lith film 40 forwardly arranged reaches a prescribed number of prints set, an exposure station 28 prints only a picture of a negative film 41 by three steps, with printing in an exposing station 26 stopped. At the end of picture printing, the lith film 40 for an illustration and the negative film 41 for a main picture are simultaneously replaced with fresh ones, and a photographic paper 26 is reversely fed by three frames, and the leading edge of an unexposed part returns to a character exposing position. This time, with the exposure station 28 put on standby, the exposure station 26 prints fresh characters. Thus, misoperation arising when film is replaced can be evaded.

Description

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

[Conventional technology]

Recently, composite print photographs have been widely used as postcards, in which an image of a person or the like is printed as a main image on photographic paper, and an illustration image such as a greeting message is printed adjacent to the main image. Such a composite photograph is formed by arranging a negative film for the main image and a lithographic film for the illustration image one after the other at a predetermined interval, and simultaneously printing these images onto photographic paper to be transported.

Conventionally, when exchanging image films, the timings of the previous and succeeding films are shifted by the interval between exposure stations in order to avoid wasting photographic paper.

[Problem to be solved by the invention]

In the conventional method mentioned above, the operator takes into account the distance between the two exposure stations when changing the film, so if the print size is changed, the timing of changing the film changes, making it easy to make mistakes. There was a problem.

[Purpose of the invention]

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a photographic composition and printing method that can avoid operational errors associated with film exchange without wasting photosensitive materials.

[Means to solve the problem]

In order to achieve the above object, the present invention interrupts printing of the preceding image when printing a set number of copies of two types of images when changing print content, and prints only the subsequent image. The number of frames corresponding to the distance between the two exposure stations is printed to complete the preceding print 1~, and then the photosensitive material is fed backwards to align the leading edge of the unexposed part with the exposure station of the preceding image. , the films of the preceding and succeeding images are simultaneously replaced with those of the next film.

[Effect]

As described above, the present invention reverses the photosensitive material at the end of the previous printing and replaces two types of films at the same time, so the photosensitive material can be used effectively and there is no need to change the film at the wrong time. .

〔Example〕

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

First, the overall configuration of the photo-compositing and printing apparatus according to this embodiment will be briefly described. In FIG. 2, a long photographic paper lO is pulled out from a supply reel 12, exposed to light, and then wound onto a take-up reel 14. This photographic paper 10
This multiple feeding is performed by four pairs of transport rollers 20 driven by morphs 16 and 18, and the photographic paper 10 is accurately fed frame by frame. Furthermore, tension rollers 22 and 24 are provided to prevent excessive tension from acting on the photographic paper 10 during the initial stage of conveyance.

Further, a dancer roller 30 is provided between the exposure stations 26 and 28 that expose the characters (x) on the illustration lithographic film 40 and the image (Y) on the image negative film 41, respectively. By pulling it downward, the spacing between the exposure stations can be adjusted. That is, the dancer roller 30 adjusts the distance between the two exposure stations according to the number of prints, and in this embodiment, the distance is always equal to three frames of print.

On the other hand, the printing light emitted from the light sources 32 and 34 is diffused by diffusion boxes 36 and 38, respectively, and then sent to the lithographic film 40 for illustration images set in a film tray (not shown). Main image negative film 41 ++t each
Shoot X. The light transmitted through each film 40.41 is transmitted through the projection lens 42.41. /13 and enters the photographic paper 10.

At the rear of the projection lens 42, 43 on the optical axis is a drive device 4.
Shutters 48 and 50 that are driven to open and close by 4.46 are arranged respectively, and when the exposure amount is determined according to the required exposure amount, 1;
is opened to allow printing light to enter the photographic paper IO.

Further, paper masks 52, 54 are provided between the shutters 48, 50 and the photographic paper 10, respectively, so that the exposure range is narrowed 11T.

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

First, the target illustration lithographic film 40 and image negative film 41 are set on each optical path. Next, the number of baked sheets (for example, 1oO
t, 7) and print size (L2L, etc.). Once the print size is determined, the projection lens 4 is adjusted accordingly.
2.43 is selected and set on the printing optical path. Also, print the exposure range of paper mask 52.54 4)
There are several sections depending on the size and the ratio of the main image to the illustration image.

On the other hand, depending on the set pudding 1 ~
A roller 30 adjusts the spacing of the exposure stations on the photographic paper 10. That is, when the print size increases, the photographic paper 10 is pulled downward, and when the print size decreases, the downward tension is loosened to maintain the interval between the exposure stations at three frames.

Next, the lights tj32 and tj34 are respectively turned on.

The printing lights emitted from these lights m32 and 34 are diffused by diffusion boxes 36 and 38, and then applied to each film 40.
．． 4th person shoots two people. Thereafter, the shutters 48 and 50 are opened and closed in accordance with the printing timing, and the characters (
Print X) and image (Y) at the same time.

By repeating this printing operation, as shown in Fig. 3 (1), the letter (X) of the lith film 4o placed on the front side is removed.
When the set number of prints (100 sheets) has been reached, print at the exposure station 26 is stopped, and then (2
) to (4), the exposure station 28 exposes both sides of the negative film 4I (1(Y) only) in 3 steps (98Y-
100Y) is printed.

Next, when the printing of image 100Y is completed, simultaneously replace the illustration image lithographic film 40 and the main image negative film 41 with the next image 6, and reverse the photographic paper 26 by 3 frames as shown in (5). and return the tip of the unexposed part to the exposed position of the letter (X).

Then, (5) to (like force), new characters IX to 3x are printed at the exposure station 26 with the exposure station 28 on standby.

Thereafter, as shown in (8), characters (X) and images (Y) are printed simultaneously as usual.

〔Effect of the invention〕

As explained above, in the present invention, the photosensitive material is reversely fed at the end of the previous printing, and 2 fil! Since different types of films are replaced at the same time, there is no waste of photosensitive material and operational errors associated with film replacement can be avoided.
