Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for producing laminated PPC copies.

(Prior Art) Conventionally, some printed materials such as design drawings have been subjected to a lamination process on the surface of the paper in order to prevent the paper surface and text portion from being stained. This type of printed material is particularly suitable for items such as design drawings that should be prevented from becoming difficult to read, and items that need to always look good, such as covers. After printing, a transparent thin synthetic resin sheet is heat-pressed and laminated to the front and back sides of the paper with an adhesive.

In this way, printed materials with laminated paper surfaces have traditionally been used for various printed materials, but such as design drawings and specific covers, etc.
For printed materials that are only produced in small quantities,
In each case, characters and figures are simply copied using a copying machine, without using a printing machine, and then laminated onto the copy paper.

When it is necessary to draw diagrams such as survey maps on thick paper that is difficult to copy, an easy way to copy them using a copy machine is to remove the copy paper before the toner is burned in by the copy machine. There is a method of transferring diagrams from copy paper to a transparent adhesive film, and then gluing the transferred adhesive film to cardboard to obtain diagrams similar to laminated products (Japanese Patent Laid-Open No. 57-196265). issue).

(Problems to be Solved by the Invention) As mentioned above, the method of creating a cover with text etc. using a copying machine is a very efficient and economical method when creating a small number of printed matter. In Although,
There are the following problems when using a copying machine.

In other words, since copies are made using a copying machine, dirt on the contact glass or dirt on the drum during copying may stain areas other than the designated characters and graphics on the printed surface, making it difficult to remove stains. thing. In addition, if the original version is made by pasting phototype letters on a mount, shadows may appear during copying depending on the thickness of the letters, and the finished product may not be as clear. Furthermore, when using the above-mentioned adhesive film, the diagram may smudge when transferred to the adhesive film, making it impossible to finish the diagram clearly. In addition, if the surface of the paper has a textured pattern formed by small irregularities, or if the paper has irregularities, toner may get into the minute depressions during copying, and when laminated, the toner may stand out.
Not finishing neatly. Further, when making copies using thick paper, there are problems such as the fact that heat is not sufficiently transferred to the toner because the paper is thick, and the characters may not be fixed.

Therefore, the present invention has been made to solve the above-mentioned problems.The purpose of the present invention is to enable easy copying using a copying machine, and to make copies of thick paper etc. by laminating the paper. Even when it is difficult to fix the text sufficiently, the heat during lamination melts the carbon and allows the text to be clearly fixed, making it possible to provide copy paper with a good finish. The purpose of the present invention is to provide a method for manufacturing PPC copies.

(Means for Solving the Problems) In order to achieve the above object, the present invention has the following configuration.

In other words, after setting the original plate in the copying machine and applying toner on the transfer paper according to the characters and figures on the original plate, the toner is removed from the copying machine before the toner is fixed on the transfer paper by heat, etc. After removing unnecessary toner and dirt on the transfer paper, a film is bonded to the surface of the transfer paper using an adhesive, and a lamination process is performed in which the film is heated and pressed to fix the toner on the transfer paper. It is characterized by

(Embodiments) Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a flow diagram showing a method for manufacturing laminated copy paper according to the present invention. The manufacturing method will be explained according to this flowchart. First, in the original plate creation step, an original plate to be copied is created using a copying machine. This original version contains the characters or figures to be copied, and for example, the characters are created in advance using phototypesetting, a word processor, etc., and then enlarged or reduced to a predetermined size using a copying machine, etc. may be pasted on the mount.

Next, in a copying step, the original plate is copied using a copying machine. In a normal copying machine, toner is attached to the portion of the transfer paper where characters and graphics are to be transferred, and then the attached toner is fixed to the surface of the transfer paper using heat or a predetermined method. But here, the toner has a predetermined character,
After adhering to the graphic, the toner is removed from the copying machine before it is fused to the receiving paper.

In Figure 1, unfixed removal refers to removing the toner after it has adhered to a specified character or figure but before it is fixed.When using a normal copying machine, toner is removed from the transfer paper. All you have to do is operate a switch while observing the state of the transferred image to remove the transfer paper before fixing.

Next, in a stain removal step, unnecessary stains on the taken-out transfer paper are removed using a piece of cloth, kneaded rubber, or the like. When removing stains, since the characters and figures are not fixed on the transfer paper, stains and unnecessary portions can be easily removed.

Next, in a lamination step, a polyester sheet is laminated on the surface of the transfer paper from which stains have been removed. This lamination process may be performed using a device that performs a normal lamination process. In this step, the paper to be transferred and the polyester sheet are heated, and the paper to be transferred and the polyester sheet are bonded via an adhesive. Then, by the heat treatment during the lamination process, the toner adhered to the transfer paper is clearly fixed onto the transfer paper. In the example, by processing the toner at around 130° C. with cardboard such as cardboard cloth, it was possible to dissolve the toner and achieve clear fixation.

Fig. 2 schematically shows the state in which the front and back sides of the transfer paper 10 are sandwiched between polyester sheets 12, 12 and laminated. By completely removing dirt in this way, a clean finish can be achieved.

Moreover, in this lamination process, since the paper to be transferred is heated from the top and bottom surfaces, it is particularly suitable for thick paper used for covers and the like. In other words, when making copies using a copying machine using such thick paper, the paper is thick, so heat does not reach the toner sufficiently during fusing, and fusing is not completed completely. According to the method of heating and bonding polyester sheets during lamination processing, heat is conducted from the top and bottom surfaces of the transfer paper even in the case of thick paper, so the toner (carbon) adhering to the paper surface is melted and fixed. This is done completely, and as a result, the characters are fixed neatly and the characters are finished clearly. Furthermore, since the surface of the transfer paper is laminated at the same time, the paper surface is protected and reinforced, and the text is protected from fading.

In addition, in the stain removal process mentioned above, the transfer paper is removed before the toner is fixed, so even if the transfer paper has minute irregularities and toner has entered the recesses, the toner can be removed cleanly. It is possible to prevent the toner from floating and making the surface dirty after lamination. Furthermore, even in the case of paper with an uneven surface, the toner (carbon) is dissolved by lamination, so the toner is firmly fixed on the uneven surface and the characters become clearer.

In addition, in cases where phototypesetting characters are pasted onto paper mounts or created by cutting and pasting, and when copying using an original version with uneven surfaces, shadows may appear on the uneven areas. Since the shadows can be neatly corrected, phototypesetting characters can be used in the original version without worrying about shadows appearing during copying. Since phototypesetting characters can be freely used in this way, it is possible to obtain laminated copy paper having a quality equal to or better than that of printed matter produced by a normal printing machine.

(Effects of the Invention) According to the present invention, as described above, when making a copy using a copying machine, the toner is copied in an unfixed state. It is easy to remove toner stains, and the transfer paper can be completely cleaned and corrected before being laminated, so the laminated copy paper is free from stains and has a clean finish. Obtainable. In addition, since the toner melts during the lamination process, the text can be firmly fixed on the paper surface, and
Characters can be clearly fixed. Furthermore, when producing a small number of printed materials, the method using a copying machine is much more efficient than the method using a printing press, and has the remarkable effect of being able to be produced at a lower cost.

The present invention has been variously explained above with reference to preferred embodiments, but the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That's true.
