Definitions
- the present invention relates to an offset printing cliché used to form a mesh pattern having a plurality of intersections and a product manufactured by the same. More specifically, the offset printing designed to solve a line width reduction occurring around an intersection of a mesh pattern. It relates to a cliché and a product made using the same.
- micro pattern formation method through such a printing technique is currently being applied to color filters, electromagnetic shielding filters (EMI filters), TFT wiring, micro pattern substrate formation, and the like.
- EMI filters electromagnetic shielding filters
- a printing technique capable of forming a fine pattern includes gravure printing, offset printing, screen printing, and the like. Of these, offset printing is particularly useful because a relatively fine printing pattern can be manufactured with a uniform thickness.
- Offset printing is to apply a paste such as ink to a printing cliché in which grooves are formed in a pattern to be printed to fill the paste in the grooves, and remove excess paste applied to the non-grooves with a doctor blade. It is a method of printing a pattern by transferring the paste filled in the grooves to a silicon blanket (off process) and retransferring the paste transferred to the silicate blanket into a to-be-printed object (set process).
- the offset printing cliché is formed by etching a metal substrate to form grooves or etching a special organic substrate. For example, a thin film of chromium or the like is formed on a glass substrate, and then a photosensitive resin is applied thereon, and a portion where a groove is to be formed is exposed by a laser beam or the like. Then, the photosensitive resin of the exposed portion is removed through development to expose the chromium film of the portion where the groove is to be formed, and then the chromium of the exposed portion is removed by etching, thereby exposing the glass and etching it again with a fluorine solution.
- the cliché for offset printing which has the groove part which has an appropriate width and depth can be manufactured.
- the surface of the glass substrate may be hybrid-nickel-treated or diamond-like coating (DLC). Methods for improving the surface strength of glass substrates have been developed.
- the fine pattern may be formed by a simple method of filling a paste into an offset printing cliché in which a desired pattern manufactured by the above method is engraved. In the case of such an offset printing method, the process is simpler than the conventional photolithography method and the manufacturing cost is reduced.
- the pattern to be printed has a plurality of intersections, there is a problem in that a line width reduction phenomenon appears around the intersections of the patterns when the pattern is formed by using offset printing.
- 1 is a photograph of a mesh pattern printed using a conventional offset printing cliché. As shown in FIG. 1, when a mesh pattern is formed using a conventional offset printing cliché, it may be seen that a line width reduction phenomenon occurs around an intersection portion.
- the reduction of the resistance characteristics due to the reduction of the line width of the intersection portion can be solved to some extent by increasing the line width.
- the transmittance decreases due to the increase in the line width, thereby causing a new problem that the luminance of the display device is lowered.
- the present invention has been made to solve the above problems, and an object of the present invention is to provide an offset printing cliché developed to solve a line width reduction or disconnection problem around an intersection with little effect on overall transmittance. It is done.
- the present invention in one aspect, in the offset printing cliché formed a mesh pattern having a plurality of intersections, the intersection of the mesh pattern is characterized in that the curved shape having a radius of curvature of 0.6 to 4 times the line width of the mesh An offset printing cliché is provided.
- the radius of curvature of the intersection is more preferably 1 to 4 times the mesh line width, more preferably 1 to 3 times, and most preferably 1 to 2 times.
- the line width of the mesh pattern is preferably about 10 to 100 ⁇ m
- the average pitch of the mesh pattern is preferably about 100 to 1000 ⁇ m.
- the cliché for offset printing may be a concave plate in which a mesh pattern is engraved or an iron plate in which a mesh pattern is embossed.
- the cliché for offset printing may be made of a metal plate, a glass plate, a hybrid nickel-treated glass plate or a DLC coated glass plate.
- the present invention provides an article comprising a mesh pattern that is curved in shape with intersections having a radius of curvature of 0.6-4 times the mesh line width.
- the product may be a wiring board, a circuit board, an electromagnetic shielding filter, or a color filter.
- the offset printing cliché of the present invention treats the intersection portion as a curve to increase the line width of the intersection portion, thereby preventing occurrence of line width reduction or disconnection at the intersection portion.
- 1 is a photograph showing a mesh pattern printed using a conventional offset printing cliché.
- FIG. 3 is a photograph showing a mesh pattern printed using an offset printing cliché of the present invention.
- 5 is a graph showing a change in sheet resistance according to the radius of curvature of the intersection of the patterns of the offset printing cliché.
- the offset printing cliché of the present invention is formed with a mesh pattern having a plurality of intersections, characterized in that the intersection of the mesh pattern is processed in a curved form.
- the intersection means a portion crossing the horizontal line and the vertical line of the mesh pattern.
- the intersection portion has a radius of curvature R of 0.6 to 4 times, preferably 1 to 4 times, more preferably 1 to 3 times, and most preferably 1 to 2 times the mesh line width W.
- R a radius of curvature
- the treatment in a curved form having a is a part of the circumference whose radius is 0.6 to 4 times, preferably 1 to 4 times, more preferably 1 to 3 times, and most preferably 1 to 2 times the mesh line width. It is preferable to make.
- the reason for limiting the shape of the intersection in this way is as follows. This is because when the radius of curvature of the curved portion is less than 0.6 times the line width, there is almost no effect of improving the resistance. When the radius of curvature is more than 4 times, the cross section becomes too large, the transmittance is deteriorated, and the linearity of the line is deteriorated. In addition, when the area of the intersecting portion becomes larger, the pitting phenomenon due to the deformation of the doctor blade increases, and the printing height of the intersection portion is considerably lowered, resulting in poor surface resistance characteristics.
- the mesh pattern will vary depending on the pattern to be printed and the applied product, but in general, it is preferable that the line width W is about 10 to 100 ⁇ m and the pitch P is about 100 to 1000 ⁇ m.
- the line width of the mesh pattern means the shortest length in the orthogonal direction of the lines constituting the mesh pattern
- the pitch of the mesh pattern means the minimum repetitive length between the lines constituting the pattern.
- the mesh line width is less than 10 ⁇ m, a large number of disconnection of the printed pattern will occur, and the final sheet resistance will be increased. If the mesh line width exceeds 100 ⁇ m, the transmittance decrease due to the printed pattern will occur. In addition, the pattern line is conspicuous. If the pitch is less than 100 ⁇ m, the decrease in transmittance occurs and if the thickness exceeds 1000 ⁇ m, the sheet resistance due to the pattern spacing not only increases, but the presence of the pattern is easily found.
- the cliché for offset printing of the present invention is preferably in the form of a plate rather than a printing plate in the form of a roll. This is because the flat printing plate is superior to the straightness of the line after printing than the printing plate in the roll form, and as a result, the surface resistance characteristics of the printed matter are more excellent.
- a concave plate in which a print pattern is engraved may be used, or an iron plate in which a print pattern is embossed may be used.
- the cliché for offset printing may be made of various materials used in the art, for example, a metal plate, a glass plate, a hybrid nickel plated glass plate, or a DLC coated glass plate. Among them, it is particularly preferable to use a hybrid nickel-treated glass plate or a DLC-coated glass plate having excellent surface strength.
- the offset printing cliché of the present invention made as described above may be usefully used when manufacturing a product having a mesh pattern having a plurality of intersections.
- the cliché for offset printing of the present invention can be used for the production of a product having a mesh pattern having a plurality of intersections, such as a circuit board, a wiring board, or an electromagnetic shielding filter of an electronic device.
- Products of the present invention formed by the offset printing cliché of the present invention is characterized in that the cross section comprises a mesh pattern made of a curved shape having a radius of curvature of 0.6 to 4 times the line width of the mesh.
- the line width is widened while the cross portion is formed in a curved shape, the line width reduction phenomenon around the cross portion is improved, and as a result, the sheet resistance property of the product is improved as compared with the related art.
- the line width of the intersection which is the main cause of the reduction of the surface resistance characteristic, and the line width of the remaining portion are maintained, thereby making almost no change in the aperture ratio, and consequently the surface with little change in the transmittance and reflectance. Since it improves the resistance characteristic, it can be particularly useful for devices related to displays.

- the product of the present invention can be manufactured through a conventional offset printing method using the offset printing cliché of the present invention.
- the paste is applied to the offset printing cliché of the present invention to fill the paste in the print pattern, the excess paste is removed using a doctor blade, and then the print pattern is transferred to the silicon blanket, which is then transferred to the to-be-printed object. It can be prepared in a way.
- a printed plate was engraved with a mesh pattern processed in a curved form having a pitch of 270 ⁇ m, a line width of 20 ⁇ m, a depth of 9.5 ⁇ m, and a cross section of a curvature radius of 20 ⁇ m.
- the paste prepared by the above method was applied onto the printing plate, the paste was filled in the recessed portion, and excess paste was removed using a doctor blade.
