Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a printer having both a front-back and a re-transfer function and a method of printing or printing security through the same, and a printing paper and a printing ribbon used in the printer, AND PHOTOGRAPHIC PAPER AND PRINTING RIBBON BEING USED IN THE PRINTER}

More particularly, the present invention relates to a printer having both a direct transfer function and a re-transfer function, a method of printing or printing security for the same, and a method for printing a photo paper and a printing ribbon will be.

The conventional photographic printing method is a silver halide method in which a photoreceptor is coated on a paper so as to have a different color according to the difference in wavelength of light and is exposed through processes of exposure, color development, fixing, bleaching, Is displayed on the paper. However, with the rapid expansion of digital cameras, photo-printing technology for outputting digital photographs is becoming popular.

As the photographic printing technique, an ink jet method, an electrophotographic method, a thermal transfer method, and a laser thermal transfer method are applied. Among them, the dye sublimation type thermal transfer printing technique belonging to the subtractive thermal transfer method has been widely used in the digital photo output market in recent years in a method of providing low noise in printing, excellent printing reliability, and high resolution close to natural color. This printing method is widely used for outputting ID cards, ID cards, driver's licenses, and ID cards.

A thermal transfer method is a method in which thermal elements mounted in a printer transfer heat to an ink ribbon, thereby transferring a black or three-color color pigment of an ink layer coated on the ribbon to a photo paper to form an image. This technique is classified into a melting type method which is applied from the beginning to facsimile and label printing, and the above-mentioned dye sublimation type.

In the melting type system, the dye of the ink layer coated on the ink ribbon and the binder material are simultaneously transferred and printed on the photo paper. In the dye sublimation type, the thermal head is heated to a high temperature of about 200 to 400 DEG C, In which the pigment contained in the ink layer is transferred and printed.

In the melting type system, when a polymer binder constituting the ink layer is melted and transferred by a thermal element, the transfer is not performed when the resin is not melted, and thus a high resolution image can not be obtained due to low color formability. On the other hand, in the dye sublimation type, the thermal energy applied to the thermal element changes according to the color density of the digital input image, and the concentration of the transferred dye is continuously controlled according to the energy amount, Implements an image.

Generally, the dye-sublimation type photographic printing method is mainly used with the direct transfer method and the re-transfer method, and various kinds of plastic cards such as a print, a credit card, a cash card, a transportation card, a membership card, The driver's license, and so on.

In this printing method, a print ribbon is brought into contact with the surface of a print, a plastic card, or an identification card to print an image, a pattern, or a character by a thermal transfer method. The print ribbon is directly adhered to the surface of a print, a plastic card, In the case of the direct printing method in which printing is performed, there is a limit in that the edge portion of the plastic card can not be printed.

In order to overcome these disadvantages, a re-transfer printer which prints by using an intermediate transfer web or an intermediate transfer film (hereinafter referred to as an " intermediate transfer film ") in addition to a print ribbon.

For example, as shown in FIG. 1, the re-transfer printer does not directly print a print ribbon on a print, a plastic card, or an identification card, but prints the print on the intermediate transfer film, ), Which is printed on the intermediate transfer film, is laminated on a photo paper, a plastic card, or an identification card. Such a technique is disclosed in Korean Patent Registration No. 10-0768730.

However, as in this patent, a conventional re-transfer printer is not equipped with a direct previous copying, and therefore, in order to perform a direct transfer job, it is necessary to separately perform a job in a direct print, which is cumbersome and incurs an additional cost.

Therefore, there is a need to develop a printer capable of both a direct transfer and a re-transfer operation in one print apparatus.

On the other hand, a dye sublimation type printing medium generally comprises a color ink ribbon and a photo paper.

The color ink ribbon is formed by mixing a synthetic dye having three primary colors of yellow (yellow), magenta (magenta) and cyan (Cyan) on one side of a polyester fabric film to form an ink layer, A heat-resistant lubricant layer is coated so as to prevent melt adhesion of the polyester film by the device.

The photo paper should have the property of efficiently absorbing the dye transferred from the ink ribbon to form a full color image and to store the image for a long time.

In the case of conventional dye sublimation type photographic paper, various synthetic resin based films such as Resin coated paper, Polyethylene terephthalate (PET) and Polyvinyl chloride (PVC) are generally used as paper, and the accumulated heat is left on the paper A foaming foam pet is formed on the upper layer of the paper in order to serve as a cushion and an ink receiving layer for recording the ink color on the foamed PET is coated on the other side of the paper, Is used with an antistatic coating to prevent static electricity.

However, such a dye sublimation type photographic paper has a very limited number of companies that sell foam pellets used as a constituent of photographic paper, and the cost is about 12 dollars per kg, which is so expensive that it is not popularized.

The applicant of the present invention has found that an ink receiving coating layer 10, a primer coating layer 20, a synthetic paper layer 30, a PET general paper layer 40, art paper or an artificial paper having an impact pressure of 110 to 200% A PE layer 60, and an electrification-treated coating layer 70. The dye-sublimation type photographic paper has the following characteristics.

This dye sublimation type photo photo paper has been manufactured by changing the composition of the existing dye sublimation type photo paper which is expensive and difficult to popularize, so that the quality of photo printing is excellent and the manufacturing cost (raw material cost) is reduced by about 60% It has brought about an advantageous effect that can be popularized.

On the other hand, in the case of re-transfer printing, the color image transferred to the intermediate transfer film is re-transferred to a plastic card or the like, or a dye sublimation type photo printing paper is used in place of the intermediate transfer film in the re- Even if a color image is first printed on a photographic paper and then transferred to the adherend again, a work of transferring the hologram onto the color image transferred to the adherend should be additionally performed. In order to transfer the hologram, it is necessary to apply the adhesive first on the color image surface, so that the operation is troublesome and time consuming.

As a countermeasure against this, it is most preferable to form an intermediate transfer film or a photo paper so that the hologram and the color image are transferred at the same time. In the case of the photo paper introduced in the above-mentioned utility model registration No. 029234 as well as the dye- It does not have a supporting layer that maintains a constant strength necessary for printing a color image and a hologram together on the photo paper itself.

Therefore, in this case, since a predetermined mechanical means is added in place of the support layer to support the photo paper, the structure of the print becomes complicated and the unit price is increased.

SUMMARY OF THE INVENTION The present invention has been developed to solve the above-described problems, and an object of the present invention is to provide a printing apparatus exclusive printer (hereinafter referred to as " printer ") which includes an identification card and a photo paper having both a forward transfer function and a re- Quot;), a method of printing or printing photos for security through the method, and a photo paper and a printing ribbon used in the printer.

In order to achieve the above-mentioned object, the printer of the present invention is a printer for photo printing, in which a feed roller and a take-up roll of a color roller or a color ink ribbon for transporting a print or a plastic card, The head is operated to perform printing directly on a printing material such as a printing material or a plastic card.

In addition, when the re-transfer function is selected, the feed roll and the take-up roll of the transport roller and the color ink ribbon, and the supply roll of the photo paper or intermediate transfer film located on the corresponding side of the color ink ribbon, The elevating roller for raising or lowering the photo paper or the intermediate transfer film is operated in correspondence with the roll and the print head so that the printing or transferring operation is directly performed on the photo paper or intermediate transfer film as the adherend.

Conventional re-transfer printers have only a re-transfer function of printing on an intermediate transfer film and laminating them on an adherend such as a card or an identification card. In order to carry out the re-transfer operation, The problem that the work is cumbersome and the additional cost is incurred due to the necessity of the operation, the present invention is configured so that the one-print and the re-transfer can be performed in one print, so that the operation is simple and quick and the printer structure is simple, Do.
