Description
本發明係為一種印刷網版的結構及其製作方法,特別係指一種改變用於包覆網布的材料層結構,使材料層結構可以導引油墨並進一步增加印刷網布的透墨量。The present invention relates to a structure of a printing screen and a manufacturing method thereof, in particular to a change in the structure of the material layer used for covering the mesh, so that the structure of the material layer can guide ink and further increase the ink permeability of the printing mesh.
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。Screen is an important tool in printing screen technology, and it can also be said to be an important foundation of printing screen. It is mainly made of tetoron fiber, nylon fiber or metal mesh material which is cross-woven in the warp and weft directions. A certain tension is formed by opening and fixing on the screen frame. The function of the screen is not only to form the pattern, but also to control the amount of ink that the ink penetrates during screen printing. Therefore, the structure of the screen version has a very large impact on the accuracy of printing, ink thickness, and ink penetration.
另一方面,在習知的網版結構中,網版的厚度取決於紗厚及材料層膜厚的加總,而當印刷線路越細時,材料層的膜厚會變薄,且當線徑變細、紗厚變薄時,整張網版的強度會減弱。基於上述原因,在習知技術中,印刷網版的刮刀面會再補強一層乳劑層以增加印刷網版的耐印度,但由於乳劑層是底片人工對位並進行曝光顯影,因此乳劑層上的開口圖案與網布上的開口圖案,兩者開口圖案之間的距離大小會偏離而不一致,進而容易造成印刷斷線。On the other hand, in the conventional screen structure, the thickness of the screen depends on the sum of the yarn thickness and the film thickness of the material layer. When the printed circuit is thinner, the film thickness of the material layer becomes thinner. When the diameter becomes thinner and the yarn thickness becomes thinner, the strength of the entire screen will be weakened. Based on the above reasons, in the prior art, the squeegee surface of the printing screen will be reinforced with an emulsion layer to increase the India resistance of the printing screen. However, because the emulsion layer is manually aligned with the negative film and exposed and developed, the The distance between the opening pattern and the opening pattern on the mesh cloth will deviate and be inconsistent, which will easily cause the printing to break.
[發明所欲解決的課題] 由上述的先前技術可知,目前在網布上藉由曝光顯影的方式在乳劑層上增加開口圖案雖然會有增加膜厚及提高網版耐印次數的效果,但反而會使透墨量減少而產生印刷斷線,以及會有生產時不容易對位的問題。 [The problem to be solved by the invention] It can be seen from the above-mentioned prior art that, at present, adding an opening pattern on the emulsion layer by exposure and development on the mesh has the effect of increasing the film thickness and increasing the number of times the screen is printed, but it will reduce the amount of ink penetration. There will be print breaks, and there will be problems that are not easy to align during production.

值得一提的是,刮刀面圖案開口寬度W1會大於貼印面圖案開口寬度W2,且第一刮刀面開口圖案邊緣3011及第二刮刀面開口圖案邊緣3013的邊緣線條為非直線線條,第一貼印面開口圖案邊緣3031及第二貼印面開口圖案邊緣3033的邊緣線條形狀為直線線條。此外,在本發明一實施例中,刮刀面圖案開口寬度W1可為50-600µm的範圍中任一數值。It is worth mentioning that the opening width W1 of the pattern on the squeegee surface will be greater than the width W2 of the pattern opening on the printing surface, and the edge lines of the first squeegee surface

另一方面,本案如此設置的優點是,當油墨從方向D1刮入刮刀面開口圖案301時,部分的油墨會直接落入貼印面開口圖案303,而另一部分的油墨會移動至三角形線條的角落C1及/或角落C2,之後油墨會再順著三角形線條的方向D2及/或方向D3移動並落入貼印面開口圖案303。因此,在本發明的結構中,是直接改變刮刀面上材料層30的結構,使第一刮刀面開口圖案邊緣3011及第二刮刀面開口圖案邊緣3013的邊緣線條設置為非直線線條,如此一來可以藉由非直線線條來導引油墨進一步落入貼印面開口圖案303,以增加印刷網版的透墨量,且如此的設置方式會增加印刷網版的耐印度。因此即使本案的刮刀面具有二次結構,但也不會使透墨量減少。On the other hand, the advantage of this case is that when the ink is scraped into the

此外,當材料層30是由第一子材料層305及第二子材料層307構成且第一子材料層305為感光乳劑層時,可藉由光蝕刻方式蝕刻刮刀面開口圖案301,使第一刮刀面開口圖案邊緣3011及第二刮刀面開口圖案邊緣3013的邊緣線條為非直線線條。因此,於上文中提到的另一種蝕刻方式即為光蝕刻,換言之,在本發明其他實施例中,可先藉由雷射蝕刻來蝕刻出開口圖案,再藉由光蝕刻方式蝕刻出非直線線條的開口邊緣,如此在製作開口圖案時就不會有對位不準的問題產生。In addition, when the
值得一提的是,在本發明的製作方法中,是使用雷射蝕刻方式來進行開口圖案及開口圖案邊緣線條形狀的製作,使用雷射時刻的優點為,可以精準地進行對位,並準確的切割出開口圖案邊緣線條所需要的形狀。再者,不使用曝光顯影的方式也可避免刮刀面開口左右距離對位不容易的問題產生。It is worth mentioning that in the manufacturing method of the present invention, the laser etching method is used to manufacture the opening pattern and the edge line shape of the opening pattern. The advantage of using the laser moment is that the alignment can be performed accurately and accurately. Cut out the required shape of the edge lines of the opening pattern.
