Description

Pattern roll and pattern forming apparatus using same {PATTERN-ROLL AND PATTERN FORMING DEVICE USING THE SAME}

The present invention relates to a pattern roll and a pattern forming apparatus used for gravure offset printing.

Recently, with the development of various portable electronic devices such as mobile phones, PDAs, and notebook computers, there is an increasing demand for flat panel displays for light and thin applications. Such flat panel displays are being actively researched, such as liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), and vacuum fluorescent displays (VFDs).

As a method of forming the metallization pattern inside the various devices or the color filter pattern of the LCD, various pattern formation methods such as screen printing or photolithography are implemented. However, screen printing has a disadvantage in that the precision of the pattern formation is inferior, and the method using the photolithography process involves the complexity of the process of laminating, exposing and developing photoresist, and limiting the formation of fine patterns. Is revealed.

In order to solve this problem, a gravure printing method of printing a pattern on a substrate using a transfer roll has been applied.

Referring to Figure 1a, this is a conceptual diagram showing a conventional gravure offset printing method.

The gravure offset printing method supplies a printing material onto the pattern roll by using a doctor knife to fill the printing material 50 on the pattern roll 10 having a negative pattern on the surface thereof and at the same time the doctor knife 40, the printing material is filled into the pattern. The doctor knife 40 is composed of a knife 42 and a holder 41 for supporting the knife, as shown in contact with the surface of the pattern roll. Subsequently, the pattern shape formed on the pattern roll 10 is transferred to the blanket roll 20 made of a material such as rubber, and the pattern 21 transferred to the blanket roll 20 is transferred back to the substrate 30. It is implemented by printing.

However, in the method of filling the printing material through the doctor knife, the amount of printing material filled into the intaglio pattern formed on the pattern roll is not uniformly filled, causing a problem of printing defects. In particular, in consideration of the intaglio pattern, the printing material is evenly filled in the same direction as the rotation direction (printing direction) of the pattern roll (horizontal direction (a)), but the longitudinal direction (vertical direction ( The printing material is not evenly filled inside the pattern of b).

This is because, as shown in FIG. 1B, when the pattern 11 in which the printing material 12 is filled has a shape in the vertical and horizontal directions as described above, the filling material preferentially moves inside the pattern in the horizontal direction a. The filling is performed while moving along the pattern in the vertical direction (b). When filling the printing material while the doctor knife and the pattern roll make line contact, the pattern of the horizontal direction is due to the very fine line width. Failure to secure enough time to fill the interior will result in a filling failure.

Referring to Figure 1c, it is a conceptual diagram for explaining another problem that occurs when forming a metal wiring pattern by the gravure offset method using the conventional pattern roll described above.

As shown, in addition to the printing failure of the vertical pattern of FIG. 1A described above, printing is extremely poor even when the intaglio pattern (print pattern) 21 formed on the surface of the pattern roll 20 becomes larger than a predetermined area (Fig. Along with this, there is a problem with 'b' in 1c). In particular, when the area of the above-described intaglio pattern is 120 * 120 µm or more, printing defects occur not only in the vertical pattern but also in the horizontal pattern as shown.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a subpattern in an intaglio pattern of a pattern roll used for gravure offset printing, thereby improving printability occurring in a predetermined area or more. In particular, the present invention provides a pattern roll and a pattern forming apparatus including the same, which can improve printability of a pattern formed in a printing direction and a horizontal direction.

The present invention has been made to solve the above-described problems, the configuration of the present invention is a pattern roll for forming a metal wiring pattern by gravure offset printing, the pattern roll has a negative pattern corresponding to the printing pattern, The intaglio pattern may provide a pattern roll, which comprises at least one subpattern.

In particular, the intaglio pattern having the above-described subpattern may be formed in a pattern having a unit area of 120 μm * 120 μm or more, in which case the subpattern is (60-120) μm * (60-120) μm At least one having a unit area of can be formed.

In addition, the depth of the subpattern in the present invention described above may be formed to 1 ~ 100㎛, the spacing interval between the subpattern may be formed to 1 ~ 30㎛.

In particular, the subpattern according to the present invention may be formed in a vertical pattern formed in the longitudinal direction of the pattern roll.

The present invention can be configured by using a pattern roll for gravure offset printing according to the present invention described above, which can be formed in the following configuration.

Specifically, a pattern forming apparatus using a gravure offset printing method, comprising: a pattern roll including an intaglio pattern corresponding to a printed pattern; And a doctor knife contacting the pattern roll to fill a printing material in the pattern; A transfer roll which receives the pattern of the pattern roll and transfers the pattern onto a substrate; It can be implemented to include more.

The printing material used in the pattern forming apparatus described above may use a viscosity of 2000 to 20000 cps, and through this, a metal pattern electrode may be formed on a touch window or the like.

According to the present invention, by providing a sub-pattern in the intaglio pattern of the pattern roll used for gravure offset printing, it is possible to improve the printability occurring in a predetermined area or more, in particular of the pattern formed in the printing direction and the horizontal direction There is an effect that can improve the printability.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation according to the present invention. In the description with reference to the accompanying drawings, the same components are given the same reference numerals regardless of the reference numerals, and duplicate description thereof will be omitted. The terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another.

Referring to FIG. 2A, this is a drawing and image showing a structure in which an intaglio pattern formed on a conventional pattern roll and a subpattern according to the present invention are implemented.

As shown in (a), the intaglio pattern 121 may be embodied on the surface of the conventional pattern roll 120. As described above, when the area of the pattern is larger than a predetermined amount, printing becomes extremely poor. .

As shown in (b), in the present invention, when the area of the pattern becomes more than a certain level, at least one or more subpatterns 130 may be formed to improve print quality. Particularly, in the present invention, when the area of the intaglio pattern formed on the pattern roll becomes 120 μm * 120 μm or more, the printing becomes remarkably poor, and the intaglio pattern formed on this area is (60 to 120) μm. It is preferable to form at least one or more subpatterns having a unit area of * (60 to 120) mu m so as to improve print quality. Of course, in consideration of the unit area, the present embodiment considers the intaglio pattern and the subpattern having a square or rectangular cross section, but the present invention is not limited thereto, and the subpattern is applied to a predetermined area or more of the above-described standard. Inclusion in the gist of the will be self-evident.

In particular, the depth T 2 of the subpattern applied in the present invention may be formed in a range of 1 to 100 μm, and the interval T 1 between each subpattern may be formed in a range of 1 to 30 μm. This is because printing becomes extremely poor even when the subpattern is formed in the above range.

Figure 2b is a table comparing the results of the print quality in the implementation of the sub-pattern according to the preferred embodiment according to the present invention described above.

In this experiment, the print quality was compared according to the subpatterns in the intaglio pattern having a certain area in consideration of the number of lines per inch (LPI). (This comparison experiment is based on changing only the number of subpatterns when the area of the intaglio pattern is 500 * 500㎛.)

When the subpattern is not formed (LPI = 0), the intaglio pattern 121 is formed on the surface of the pattern roll 120 and then printed by the gravure offset method. It can be seen that only the surface of the unprinted substrate 140 appears.

When the LPI forms a large number of auxiliary patterns 130 with "100", referring to the printing result, although the fine unprinted area 151 appears, the printed area 150 is clearly printed, and in the ultra-fine area Such an unprinted area is negligible, and corresponds to an error that can be used as a product.

Even when the LPI is "200", "300", or "400", the unprinted areas 161, 162, 171, and 181 appear, but the clear print areas 160, 170, and 180 can be confirmed. It corresponds to the error that there is no problem in use as a product at all.

That is, when the sub-pattern is formed in the intaglio pattern of a certain large area, the conventional problem in which printing does not occur at all can be solved, and a markedly improved print quality can be realized.

2C illustrates another example of implementing a subpattern according to the present invention.

As shown, in the case where the subpattern 220 of 60 * 60 μm is formed in the intaglio pattern 210 having the pattern width of 120 μm, the printing result shows that the printing is markedly defective in the absence of the sub pattern. In the case of the present invention having a subpattern, the boundary between the vivid print area 230 and the area 213 without the intaglio pattern is clearly distinguished, and thus the print quality is remarkably improved.

In addition, in the case of the intaglio pattern 240 having a pattern width of 720 μm, when a plurality of 60 * 60 μm subpatterns 250 are disposed, no printing is performed at all when there are no subpatterns (260; only the substrate to be printed is shown). In the present invention, the printed area 270 appears to be clearly printed, and it can be seen that the boundary of the distinction from the other areas 271 without a pattern is clearly distinguished.

Figure 3 shows an image showing an actual implementation of the pattern forming apparatus according to the present invention and a pattern image printed through it.

As shown, the doctor knife is in contact with the pattern roll 100 is formed including a knife 220 and the jig portion 210 for supporting the knife, the pattern roll surface as shown in the various vertical and horizontal patterns A pattern of a negative electrode is formed, and then transferred to a substrate. In this case, in the case where the above-described vertical pattern or the horizontal pattern is provided with the subpattern according to the present invention, the printing of the portion b printed by the conventional vertical pattern is remarkably excellent when compared with FIG. 1A. It can be confirmed. The printing material used in the pattern forming apparatus according to the present invention is preferably used having a viscosity of 2000 ~ 20000cps.

In the foregoing detailed description of the present invention, specific examples have been described. However, various modifications are possible within the scope of the present invention. The technical idea of the present invention should not be limited to the embodiments of the present invention but should be determined by the equivalents of the claims and the claims.
