Description
本發明係為一種印刷網布製作成的印刷網版的結構及其製作方法,特別係指一種在印刷網布的開口圖案中的經緯線上形成一離型層,以讓油墨可更輕易地與開口圖案分離的印刷網版及其製作方法。The present invention is a structure of a printing screen made of a printing mesh fabric and a manufacturing method thereof, in particular, it refers to a release layer formed on the warp and weft lines in the opening pattern of the printing mesh fabric, so that the ink can easily communicate with the opening Printed screen with separated patterns and its production method.
網版是印刷網版技術中的重要工具,也可以說是印刷網版的重要基礎,其主要係由特多龍纖維、尼龍纖維或金屬材質的網材以經、緯方向交叉編織後,透過一定的張力張開復固定於網框上而形成。網版的功能除了在於形成版紋外,也可控制網版印刷時油墨所透過的墨量。因此,網版本身的結構對於印刷的精密度、油墨厚度以及油墨的滲透量都會產生非常大的影響。此外,在高精細圖案印刷的情況中,線寬越細印刷膜厚也越薄,而圖案線條越細,油墨與基板的接觸力也會減少,因此部份的油墨都會留在乳劑面或經緯線紗上,結果就會造成印刷透墨不良斷線或膜厚變薄,而過往技術大多都採用在網版上噴塗鍍膜以形成一層氟素疏水層,來減少油墨與網版開口圖案中接觸力,但此種方式的成本貴,同時鍍膜層薄,也無法耐印刷摩擦。Screen is an important tool in printing screen technology, and it can also be said to be an important basis for printing screen. It is mainly made of Tedron fiber, nylon fiber or metal mesh material that is cross-woven in the warp and weft directions. A certain tension is formed by expanding and fixing on the frame. In addition to the function of screen printing, the function of screen printing can also control the amount of ink transmitted through screen printing. Therefore, the structure of the screen body has a great influence on the precision of printing, the thickness of the ink and the amount of ink penetration. In addition, in the case of high-definition pattern printing, the thinner the line width, the thinner the printing film thickness, and the thinner the pattern lines, the contact force between the ink and the substrate will be reduced, so part of the ink will remain on the emulsion surface or warp and weft On the yarn, the result will be poor printing ink breakage or thin film thickness, and most of the past techniques used spray coating on the screen to form a layer of fluorine hydrophobic layer to reduce the contact force between the ink and the screen opening pattern However, the cost of this method is expensive, and at the same time, the coating layer is thin, and it is not resistant to printing friction.
另一方面,網版的製造原理,係利用網版的經、緯線交織後所形成之網布與感光乳劑對紫外線光的化學反應來進行感光製版,使非印紋的部分受光硬化而堵住網孔,而印紋部份則因感光乳劑並未經過化學反應,會在遇水時溶解而鏤空,進而形成印刷時所需的開口圖案。進行網版印刷時,操作者能利用刮刀施壓進而刮印油墨,使得油墨透過鏤空的網孔在被印物上印上圖案,以達到印刷的目的。On the other hand, the manufacturing principle of the screen plate is to use the chemical reaction between the mesh cloth formed by the warp and weft of the screen plate and the photosensitive emulsion to ultraviolet light to make a photosensitive plate, so that the non-printed part is blocked by light and hardened The mesh, and the printed part is because the photosensitive emulsion does not undergo a chemical reaction, it will dissolve and meet the hollow when it meets water, and then form the opening pattern required for printing. When performing screen printing, the operator can apply pressure with a squeegee to scrape the ink, so that the ink prints a pattern on the object to be printed through the hollow mesh to achieve the purpose of printing.
然而,在習知的網版製造過程中,特別係指感光乳劑與包括金屬材質網布的印刷網版的製造過程中,由於金屬材質有反射光線的特性,導致塗佈於網版印紋部分的感光乳劑會受到金屬反射的紫外線光而硬化,進而導致原本網版預計鏤空的印紋部分因為硬化的乳劑而形成截點,影響網版的透墨量以及印刷的結果,或是由於細線油墨之吸附作用力而造成塞版斷線,因此傳統感光乳劑製版方式,在高精細圖案印刷開口線徑35µm以下容易塞版斷線,造成大量生產不良及浪費成本。However, in the conventional screen manufacturing process, especially refers to the manufacturing process of photosensitive emulsions and printing screens including metal mesh cloths, the metal material has the characteristics of reflecting light, resulting in coating on the screen printing part The photosensitive emulsion will be hardened by the ultraviolet light reflected by the metal, which will cause the original printed screen to be cut out due to the hardened emulsion, which affects the ink penetration of the screen and the printing result, or due to the fine line ink Due to the absorption force, the blocking plate is broken, so the traditional photosensitive emulsion plate-making method is easy to block the plate to break when the line diameter of the high-precision pattern printing opening is less than 35µm, resulting in a large number of poor production and waste of cost.
此外,高精細圖案印刷使用感光乳劑所製作的網版,容易出現耐印度不足的狀況,使得印刷過程容易因為網版破損而中斷,其原因在於感光乳劑本身強韌度外,金屬絲網為了增加開口率而將線紗變細,造成強度變弱也是原因之一,進而造成高精細圖案印刷上的時間以及成本增加。為了達到所需之高精細圖案,目前習知技術中會使用高張力,例如大於24N/cm的金屬網版來進行印刷,以增加離版效果。然而,金屬網版在印刷時,容易因線紗變細而導致韌性不足,並在印刷時使得金屬網版與刮刀下壓時,容易出現網版破損以及溢墨等狀況。因此,習知的網版製造過程不但繁雜耗時且成效亦不佳,使得高精細圖案印刷品質不穩定,無法達到理想的產品品質。In addition, high-precision pattern printing screens made with photosensitive emulsions are prone to insufficient resistance in India, making the printing process easy to be interrupted due to broken screens. The reason is that in addition to the strength and toughness of the photosensitive emulsion itself, wire mesh It is also one of the reasons that the thread yarn becomes thinner due to the aperture ratio, resulting in weaker strength, which in turn increases the time and cost of printing high-definition patterns. In order to achieve the required high-definition patterns, the current conventional technology will use high tension, such as metal screens greater than 24N/cm for printing, to increase the effect of off-plate. However, when printing a metal screen, it is easy to make the yarn thinner, which leads to insufficient toughness. When printing, the metal screen and the blade are pressed down, and the screen is likely to be damaged and the ink overflows. Therefore, the conventional screen manufacturing process is not only complicated and time-consuming, but also has poor results, which makes the quality of high-definition pattern printing unstable and cannot achieve the desired product quality.
基於上述原因,如何提供一種全新的高精細圖案印刷網版結構及其製作方法,使油墨在通過印刷網版的開口圖案後,不會滯留在開口圖案中的經緯線上或開口圖案面上,同時可以讓被印物與網版容易離版以進一步達到高精細圖案透墨量最佳化及降低成本的目的,乃是待解決的問題。Based on the above reasons, how to provide a new high-definition pattern printing screen structure and its manufacturing method, so that after the ink passes through the opening pattern of the printing screen, it will not stay on the latitude and longitude lines in the opening pattern or the opening pattern surface, while It is a problem to be solved that the printed matter and the screen can be easily separated from each other to further achieve the purpose of optimizing the ink penetration of high-definition patterns and reducing costs.

綜上所述,本發明成功地提供了一種具有離型層的印刷網版及其製作方法,本發明是在印刷網版的開口圖案中且靠近網版貼印面的一側的金屬經線及金屬緯線上形成一離型層,離型層的存在可以讓油墨輕易的被留在被印物上,且大多數的油墨並不會留在開口圖案中高分子材料層的面上或金屬經緯線上,如此一來,可使得印製出來的高精細圖案不會斷線與膜厚不會太薄。再者,本發明可將網版的開口圖案設置成沙漏形狀,沙漏形狀的開口圖案可做為細線寬(10~25um)網版印刷以有效降低晶矽太陽能電池用正面電極印刷之油墨(銀漿)耗用成本,同時提高產品性能效率及價值。In summary, the present invention successfully provides a printing screen with a release layer and a manufacturing method thereof. The present invention is a metal warp and a side near the printing surface of the screen in the opening pattern of the printing screen and A release layer is formed on the metal weft, and the presence of the release layer allows the ink to be easily left on the printed matter, and most of the ink will not remain on the surface of the polymer material layer in the opening pattern or on the metal warp and weft In this way, the printed high-definition patterns will not be broken and the film thickness will not be too thin. Furthermore, the present invention can set the opening pattern of the screen into an hourglass shape. The opening pattern of the hourglass shape can be used as a thin line width (10~25um) screen printing to effectively reduce the ink (silver) printed on the front electrode of the crystalline silicon solar cell.
