Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) This invention combines an image and a character on a long photographic material in order to produce a print product called a so-called post card, greeting card, or the like. And a method for automatically printing photos sequentially and automatically. (Prior Art) This type of photographic printing method is based on the mechanical difference between a device for printing an image on a negative film (11) and a device for printing characters on a lith film (12). In the transport direction of (10), they are separately arranged side by side at predetermined intervals in front and rear, and are sequentially baked separately in the form of stepping stones and simultaneously. Therefore, in the conventional photographic printing method, as shown in FIG. 4, the combination of printing an image and text in one frame (D) on a long photographic light-sensitive material (10) involves printing with an image negative. At a fixed interval before and after printing characters with a squirrel film, each stepped stone is printed separately and simultaneously, and the photographic light-sensitive material (10) is fed one by one from the start to the end of printing of I to III. By printing the stepping stone-shaped image (A) and the character (B) spaced at the front and back sequentially into the already printed stepping stone portion (C),
A print of one frame (D) incorporating the image portion (A) and the character portion (B) was continuously printed on a long photographic material (10). (Problems to be Solved by the Invention) However, in a conventional photographic printing method in which an image and a character are successively printed in the form of a stepping stone over two adjacent frames on a photographic light-sensitive material, the image and characters are uniformly obtained. To simultaneously print images and characters in one frame while simultaneously printing the images and characters in a stepping shape on a long photographic photosensitive material that is sequentially fed in one direction. At the beginning and end of printing on the photographic material, unexposed corners are created that are not printed at all when the printing contents are changed, and this causes insignificant blanks at the start and end of printing, and further when the printing contents are changed. Each incomplete frame consisting only of the image or the character having the image was printed, and the photographic material was wasted. SUMMARY OF THE INVENTION An object of the present invention is to effectively utilize a photographic light-sensitive material by eliminating a missing portion which is not printed at the start and end of printing in a series of photographic printing processes. (Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention is to print images and characters by combining and printing images and characters in one frame on a long photographic material. The image and the text are printed simultaneously on two adjacent frames on the photographic material at the same interval in the form of a stepping stone, straddling the front and back, and the position before the step of printing the stepping stone following the front side of the printing portion at the rear position. In the method in which the images or characters are fed one by one so that the images or characters can be sequentially transferred, the printing (frame feed) of the photographic photosensitive material is operated in a normal or reverse direction, and the images and characters are simultaneously transferred to the photosensitive material.
Alternatively, the present invention proposes a photographic printing method characterized in that only one of the images is burned in and transferred, and images and characters are sequentially combined and printed in one frame. (Effect) The stepping portion can be buried by transferring the image and the character simultaneously or only one of them in the transport operation of the photographic light-sensitive material. That is, at the start of printing, a long photographic photosensitive material that has been conveyed to the normal exposure position of images and characters spaced apart before and after, or that has been subjected to the previous normal (image only) printing exposure, is removed by a predetermined length. In the place where the image or the character at the rear position is printed back only at the place where the image or the character at the rear position is reversely fed, the image or the character at the previous position is next to the image or the character to be printed next in the stepping stone shape on the front side of the printing portion. The photographic light-sensitive material is forward-forwarded and conveyed to be printed, and the image and characters are simultaneously printed in the form of a stepping stone over two adjacent frames, thereby forming the first image.
Images and characters are combined and printed up to the frame. Thereafter, the images and characters are alternately transferred in the form of a stepping stone over two adjacent frames while successively moving forward one frame at a time, and then printed, whereby each frame in which the images and characters are combined is continuously printed. Can be At the end of printing, forward-forward printing only the image or character at the previous position to finally combine the image at the post-position or the character at the unexposed place adjacent to the front side of the character after printing Alternatively, the characters are printed and the image and the characters are combined and printed up to the last one frame. If you want to change the print content in the middle, print only the image or character at the previous position, print only the rear position of the image or character replaced with the negative of the new content without frame advance, and advance the photosensitive material by frame. By printing the image and the characters at the same time, the unexposed portion in the form of a stepping stone at the time of change can be satisfied. (Examples) Next, specific examples of the photographic printing method according to the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing the relationship between a printing apparatus and a photographic photosensitive material at the beginning of printing, and FIG. 2 is an explanatory view of the same at the end of printing, and FIG. FIG. 4 is an explanatory view showing the relationship between the printing apparatus and the photographic material when the contents are changed, and straddles two adjacent frames on a long photographic material (1) mounted for frame advance. The image (X) and the character (Y) are spaced apart from each other, and a device (2) for printing the image at the front position according to the transport method so as to sequentially print the characters in a stepping stone shape. Attaching devices (3) are arranged side by side and each device (2)
The optical axis (2a) (3a) of (3) is provided so as to face the surface of the photographic material (1). The distance between the image (X) and the character (Y) differs depending on the length of image printing and character printing corresponding to one frame (W), and is obtained by adding the length of image printing at the preceding position to this length. Are the jumping intervals, and this distance is juxtaposed between the printing devices (2) and (3).
On the other hand, the frame feed length of the photographic material (1) is one pitch (W) and the length of image printing and character printing corresponding to the frame allowance (V) is one pitch. FIG. 1 shows an image (X) and a character (Y) such as a sentence in one frame (W) instead of a normal print (U) without printing a character which has been printed on a long photographic material (1). Regarding the start of printing a print to be printed in combination with I, the photographic photosensitive material (1) is usually used after the exposure of the print (U) is completed.
The character at the rear position is returned when the feed is returned by a length equivalent to one frame (W) minus half of the length of the normal print (U) and image (X) and returned. Only the character (Y ₁ ) is printed by operating only the printing device (3). In the case of II, the photographic material (1) is fed forward by one frame (W) and frame allowance (V) to print the image at the previous position. by operating device (2) and the character printing apparatus of the rear unit (3) and at the same time to expose the normal print (U) and the character (Y ₁₎ image between (X _1), character (Y ₂ ) is printed in the form of a stepping stone, and in III, by operating the two devices (2) and (3) at the same time while sequentially moving forward by one frame (W) and the frame allowance (V), the image ( X ₁ ) and character (Y ₁ ) are combined in one frame with image (X ₂ ) and character (Y ₂ ) On the long photographic light-sensitive material (1). FIG. 2 shows the image (X ₉₉ ) and the character (Y ₁₀₀ ) in step I at the end of printing in FIG.
₁₀₀ )), the photographic light-sensitive material (1) is forward-forwarded by one frame (W) and the frame allowance (V) in II, and only the image (X ₁₀₀ ) at the previous position is formed. by exposing, combined with baked image (X ₁₀₀₎ on the stepping stone portion (Z _100), the last one frame consisting image and (X ₁₀₀₎ and character (Y ₁₀₀₎ is formed. Figure 3 is a case of changing the baking contents in the middle, baking and I in the front and rear image (X ₄₉₎ character (Y ₅₀₎ simultaneously, II in photographic material (1) frame (W) (V) Feed image (X ₅₀₎ of the front position by the burn. Next, replace the image negative and the character negative with the new contents without frame advance in III, print only the character (Y ₁ ) at the rear position, and use IV for the photographic material (1)
The image (X ₁ ) and the character (Y ₂ ) before and after are forwarded by frames (W) and (V) simultaneously, and the images (X ₁ ) and characters (Y ₂ ) are burned in steps. Continuous printing is obtained by preventing the occurrence of blank portions. In this printing method, images and characters which are simultaneously printed in the form of a stepping stone, but the printing contents are as shown in FIG. II, where the image at the front position is the image of the previous one frame (X ₁ ) and the image at the rear position is The characters are printed by straddling the next one character (Y ₂ ) over each two adjacent frames, and the image and the characters having the same contents are sequentially printed in one frame (W) by being squeezed back and forth. Combined. (Effect of the Invention) The present invention relates to continuous printing of one frame in which an image and a character are combined on a long photographic light-sensitive material. Baking simultaneously in a stepped manner over a step, and successively baking the lithographic printing material in the forward direction while feeding the photographic photosensitive material forward so that the next stepped-stone printing unit is fed into the unexposed (blank) part of the stepped-stone printing unit. At the beginning of baking, the photographic light-sensitive material is retracted backward by a certain length, and only the character (or image) at the rear position is printed. At the end of printing, only the image (or character) at the previous position is printed. The photographic light-sensitive material is conveyed in the forward and reverse directions, and furthermore, operations such as printing the preceding and following images and characters simultaneously, or printing one of them, start and end printing in the photographic printing process, or change the printing contents during printing. Since no blank space is generated due to unexposure in a part of each frame, completely eliminating the loss in which one frame of the imperfectly completed photographic material has been discarded until now is completely eliminated. This has the effect that the photographic light-sensitive material can be used effectively.
