Description

The present invention relates to a thermal transfer ink ribbon for use in indirect thermal transfer printers, and more particularly, to a thermal transfer ink ribbon capable of accurately recording even information on special hues and patterns without increasing the number of thermal transfer processes in the printer. and an indirect thermal transfer recording method.

ID cards such as credit cards, shop cards, and membership cards have traditionally included personal attribute information such as name, membership number, and face photo to identify the owner, and store name and mark for shop cards. , logos, etc. are recorded. In addition, complicated patterns, holograms, and printing with special inks may be printed on the surface of the card as a security function.

The equipment for offset printing and screen printing, which has been conventionally used to record information on such ID cards, is large and expensive, and takes a long time to prepare, and is not applicable to small-lot production or recording of individual information. Since this is difficult, in recent years printers using a digital printing system have come to be used, and it has become possible to easily record individual information on cards. Among various printers, a thermal transfer ink ribbon provided with color ink layers of cyan (C), magenta (M), yellow (Y), and black (K) is thermally transferred to a recording medium with a thermal head. Thermal transfer recording printers are known to be able to obtain high print quality with a simple mechanism.

Thermal transfer recording methods include a direct thermal transfer method in which an image is thermally transferred and recorded directly from a thermal transfer ink ribbon onto a recording medium, and an image that is thermally transferred and recorded from a thermal transfer ink ribbon onto an intermediate transfer film, and then transferred by a heating and pressurizing means such as a heat roller. There is an indirect thermal transfer system that retransfers an image onto a recording medium, and it is known that all of them have high print quality and can reproduce details of facial photographs and character information. In addition to image recording, by using a thermal transfer ink ribbon with various functional layers added, special recording other than recording of color images and ink characters on the recording medium can be performed.

FIG. 6 is a schematic diagram showing a general mode of performing thermal transfer recording by an indirect thermal transfer recording system using a conventional thermal transfer ink ribbon. K, a thermal transfer ink ribbon in which each panel of a primer serving as an adhesive layer is painted in a frame-sequential manner is used to record a facial photograph 102 and a mark 103 on a recording area 101 of an intermediate transfer film 100 . Next, after the character recording 104 is performed, the adhesive layer 105 is transferred from the primer panel over the entire area to be retransferred to the recording medium.

In this case, the mark 103 is also recorded by superimposing CMY, but marks and logos of brands and companies often have characteristic colors (special colors), and superimposing CMY is accurate due to the limits of the color reproduction range. was difficult to reproduce. Therefore, conventionally, as shown in FIG. 7, a panel of special color thermal transfer ink is added to the thermal transfer ink ribbon for the required number of colors, and marks and logos including special colors are recorded by transferring this special color thermal transfer ink. What was done was done. At this time, the special color ink panel is used as a special functional ink panel to provide the recording medium with a special function. As functional inks, various inks such as fluorescent inks, infrared absorbing inks, and pearl inks are known. It is used to create visual effects.

For example, in Patent Document 1, on one side of a strip-shaped base material, each color ink layer of yellow, magenta, and cyan is formed, followed by substantially colorless and transparent layers that emit red, green, and blue light when irradiated with ultraviolet rays. Disclosed is a thermal transfer ink ribbon in which each luminescent color ink layer is arranged side by side, and the luminescent color ink layer can form an image that can be seen only when irradiated with ultraviolet rays, so that images with special visual effects can be recorded and security is improved. According to the company, it is possible to provide an authentication image formed product. However, the thermal transfer ink ribbon with such an additional special ink panel requires an extra process for recording on the special ink panel, and has a problem of inefficiency due to the time required for recording.

In addition, the addition of the ink panel increases the length of the thermal transfer ink ribbon, which causes the problem of increasing the diameter of the wound roll. When producing a thermal transfer ink ribbon by gravure printing, it was necessary to separately prepare a large-diameter printing cylinder. Furthermore, for example, when recording marks and logos with special inks other than yellow, magenta, cyan, and black, such as the above-mentioned luminescent color inks, and special color inks, logos, marks, crests, etc. Even if the ink is very small, the entire ink layer is used during transfer, and most of it is wasted. Further, the definition of a recorded image is limited by the definition of a thermal head, which is a recording head, and it is impossible to reproduce a pattern with higher definition.

Further, the invention according to claim 6,
An image is recorded on a recording medium by forming a recorded image on an image-receiving layer provided on an intermediate transfer film using a thermal transfer ink ribbon and a thermal head, and thermally and pressure-transferring the formed recorded image onto a recording area of the recording medium. In an indirect thermal transfer recording method, the thermal transfer ink of the ink panel is sequentially transferred from the thermal transfer ink ribbon according to any one of claims 1 to 5 onto the image receiving layer according to image data of a recorded image, and In an ink panel provided with a special color ink portion, the indirect thermal transfer recording method is characterized in that the thermal transfer ink of the ink panel and the special color ink portion are transferred in the same step.

According to the first aspect of the present invention, the special color ink portion is provided in a part of the ink panel having at least the same area as the recording area of the recording medium on which the image is recorded. In the same process as the process of transferring the panel, in the part of the special color ink part, the special color ink part made of the special color ink of a different color from that of the ink panel or the ink exhibiting a different visual effect than the normal thermal transfer ink is transferred. Thus, the thermal transfer recording of the spot color ink portion can be efficiently performed without requiring an extra process. For example, if the special color ink is a special color thermal transfer ink that is difficult to stably and accurately reproduce due to heat unevenness and the limit of the color reproduction range when three primary colors are superimposed, such a special color is applied only once instead of being color superimposed. Since recording can be performed by transfer in the process of (1), thermal transfer recording can be stably and accurately reproduced. Such features are often used in logos, marks, coats of arms, etc., and thus are highly convenient.

Moreover, since the special color ink section is provided only in a part of the ink panel, that is, only in a necessary part, the special color ink is not wasted. In addition, if the special color ink portion is made of functional ink, it is possible to impart security to the recording medium.

In the case of infrared-absorbing ink, infrared-reflective ink, and infrared-transmitting ink, patterns that cannot be seen with visible light emerge when exposed to infrared rays. A pattern having a special visual effect such as exhibiting a hue can be thermally transferred and recorded on the recording medium. For example, the recording medium can be provided with an anti-counterfeiting effect, and effects such as security can be obtained.

According to the fourth aspect of the present invention, a pattern having a higher definition than the resolution of a thermal head, which is a recording head for thermal transfer recording, is previously formed as a pre-pattern on the special color ink portion by another method such as gravure printing. In thermal transfer recording, by transferring the entire pre-pattern solidly, a high-definition pre-pattern can be transferred and recorded regardless of the resolution of the thermal head, and high-definition logos, fine patterns, hologram patterns, etc. can be easily printed. Thermal transfer recording is possible.

According to the fifth aspect of the invention, when performing recording by the indirect thermal transfer method, the adhesive layer of the primer panel can be superimposed and transferred onto the recorded image transferred from the ink panel onto the intermediate transfer film. , the adhesiveness to the recording medium can be further enhanced when re-transferred from the intermediate transfer film to the recording medium.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiments described below. Equivalent members and the like are denoted by the same reference numerals, and description thereof may be omitted.

FIG. 1 is a schematic diagram of one embodiment of the thermal transfer ink ribbon of the present invention and thermal transfer recording using it. In the thermal transfer ink ribbon 10 of the present embodiment, four color ink panels of cyan, magenta, yellow, and black are provided on one side of a heat-resistant base film in a frame-sequential manner, followed by a primer panel. It is a thermal transfer ink ribbon for indirect thermal transfer recording. However, some of the cyan, magenta, and yellow ink panels are special color ink portions of special color 1, special color 2, and special color 3. FIG. The thermal transfer ink areas of cyan, magenta, and yellow and the thermal transfer ink areas of special color 1, special color 2, and special color 3 should be appropriately set and divided according to the printing specifications such as the position and size of the image to be printed. Good luck.

The intermediate transfer film 100 has, on one side of a heat-resistant substrate, a transfer layer having a multi-layer structure of two or more layers including a release layer and an image receiving layer. The width C' of the intermediate transfer film 100, the length B' of the recording area 101 in the transport direction (direction of arrow A), the width C of the thermal transfer ink ribbon 10, and the transport direction length of each ink panel including the special color ink portion B is set to have a size that covers at least the recording area of the recording medium on which recording is finally performed.

The thermal transfer ink ribbon 10 and the intermediate transfer film 100 are overlapped so that the image-receiving layer and the ink panel face each other, and are conveyed in the conveying direction. A predetermined image is recorded on the image-receiving layer of the intermediate transfer film 100 by thermal transfer. Similarly, the thermal transfer ink of each ink panel is sequentially recorded in the recording area 101 in an overlapping manner. The thermal transfer ink ribbon 10 and the intermediate transfer film 100 are usually supplied in a roll-like state, and are used while being unwound from the roll.

At this time, a general color image 22 such as a face photograph is recorded by superimposing thermal transfer inks of cyan, magenta, and yellow, which are the general three primary colors of the ink panel, and is reproduced by superimposing the general three primary colors. A spot color pattern 103 having a spot color that is difficult to print is printed with spot color 1, spot color 2, and spot color 3, which are spot color thermal transfer inks. The color of each special color thermal transfer ink may be appropriately set according to the color of the special color pattern 103 .

As shown in FIG. 4, the thermal transfer ink ribbon 10 is transferred over the length B' of the recording area 101 over the length B' of the recording area 101, thereby thermal transfer recording of one color is performed. In terms of processes, the thermal transfer ink ribbon 10 of the present invention can be transferred over the same length B, and recording of two colors, for example, cyan and special color 1, can be performed in one process. Moreover, although the recording of the spot color is possible, the length of the entire set of ink panels is not increased, and the roll diameter of the thermal transfer ink ribbon 10 is not increased.

Next, character information 104 is recorded with black ink, and an adhesive layer 105 is transferred from the primer panel over the entire area to be retransferred onto the recording medium. That is, by repeating the thermal transfer five times over the length B in the conveying direction, thermal transfer recording of the seven colors of cyan, magenta, yellow, special color 1, special color 2, special color 3, and black, and transfer of the primer are performed. , which is more efficient than the conventional thermal transfer ink ribbon process shown in FIG. After that, the intermediate transfer film 100 is overlaid so that the side to which the adhesive layer 105 is transferred faces the final recording medium, and the recording is transferred to the recording medium by thermal pressure transfer.

FIG. 2 is a schematic diagram of a second embodiment of the thermal transfer ink ribbon of the present invention and thermal transfer recording using it. In this embodiment, the special color ink section is provided in the upper right corner of the ink panel. Such a mode can be used when the area of the spot color pattern (logo) 106 to be printed by transferring the spot color ink portion is only the upper right corner of the printing area. The recording process is the same as the form shown in FIG.

In the example shown in FIGS. 1 and 2, the spot color ink portions are provided in all the CMY ink panels, that is, at three locations, but one or two spots may be provided depending on the number of required spot colors. In the present embodiment, the special color ink portion is provided only in a portion necessary for forming the special color pattern 106, so that the special color ink is rarely wasted. Also in this embodiment, by repeating the thermal transfer five times, the thermal transfer recording of seven colors and the transfer of the primer are performed, which is efficient.

FIG. 3 is a schematic diagram of a third embodiment of the thermal transfer ink ribbon of the present invention and thermal transfer recording using it. In this embodiment, the special color ink section 31 is provided in a part of the black ink panel. Here, the pattern provided on the special color ink portion 31 is a pre-pattern (mark) 32 formed in advance by ordinary gravure printing. That is, in the special color ink portion 31, a pre-pattern 32 is provided by being printed by gravure printing between two thermally transferable binder layers.

When transferring to the intermediate transfer film 100, the pattern is not formed by a thermal head as in the above-described embodiment, but by thermally transferring the portion including the pre-pattern 32 from the special color ink portion 31 to the intermediate transfer film 100. , the pre-pattern 32 is thermally transferred and recorded. As the pre-pattern 32, a logo, a mark, an emblem, a fine pattern, or the like can be provided by gravure printing, but a so-called hologram pattern can also be provided in addition to the gravure printing method. Also in this embodiment, by repeating the thermal transfer five times, in addition to the thermal transfer recording of four colors, the special color ink portion 31 and the primer are transferred, which is efficient.

FIG. 4 is a schematic diagram of a fourth embodiment of the thermal transfer ink ribbon of the present invention and thermal transfer recording using it. In this embodiment, the black ink panel is provided with the special color ink section 41 as in the embodiment shown in FIG. In the special color ink portion 41, a printed pattern 42 made of pearl ink having a pearly luster is provided in advance as a pre-pattern as a security pattern. The method of providing can be the same as in the above-described third embodiment.

As a result, it is possible to form not only a mark as mere visual information but also a security pattern. For the printed pattern 42, other than pearl ink, fluorescent ink, infrared absorbing ink, infrared reflecting ink, infrared transmitting ink, color shift ink, etc. can be suitably used. Also in this embodiment, by repeating the thermal transfer five times, in addition to the thermal transfer recording of four colors, the special color ink portion 41 and the primer are transferred, which is efficient.
