Description

一种印刷网版
本发明要求2014年9月24日递交的发明名称为“一种印刷网版”的申请号201410495111.4的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及印刷技术领域，尤其涉及一种印刷网版。
背景技术
网版印刷是一种多用途的印刷技术，在各种行业中均有使用，目前在平板显示行业也广泛使用。所谓网版印刷是将浆料涂覆在印刷网版上，然后把印刷网版上带有图案的浆料转印在承载物上的过程。其中，印刷网版主要是由网框及网布所组成。但是，目前的网布的结构单一，严重限制了网版印刷的适用条件，从而无法满足网版印刷的需求。
发明内容
本发明所要解决的技术问题在于提供一种印刷网版，以扩大网版印刷的使用条件来满足网版印刷的各种需求。
为了实现上述目的，本发明实施方式提供如下技术方案：
本发明供了一种印刷网版，包括多条经线及多条纬线，所述经线及所述纬线以上下交错的方式进行编织，以形成多个开口，所述经线和/或所述纬线的表面凸凹不平。
其中，所述经线和/或所述纬线的表面成锯齿状。
其中，所述经线和/或所述纬线的表面成不规则波浪状。
其中，所述经线和所述纬线的材质为不锈钢材质。
其中，所述经线与所述纬线的每一个交错处被固定且分别形成一个网结。
其中，所述多个经线的线径相同，且为第一线径，所述多条纬线的线径相同，且为第二线径，所述网结具有第三线径，其中，所述第三线径大于所述第 一线径以及所述第二线径。
其中，所述经线及所述纬线以上下交错的方式进行编织形成网布，所述网布包括预设区域及非预设区域，所述预设区域内的经线、纬线及网结的线径分别为第四线径、第五线径及第六线径，所述非预设区域内的经线、纬线及网结的线径分别为第七线径、第八线径及第九线径，其中，所述第六线径大于所述第四线径及所述第五线径，第九线径大于所述第七线径及第八线径，所述第四线径大于所述第七线径，所述第五线径大于所述第八线径，所述第六线径大于所述第九线径。
其中，所述第四线径及第五线径相等，所述第七线径及第八线径相等。
其中，所述开口为正方形。
其中，所述印刷网版还包括网框，所述以上下交错方式编织的经线及纬线固定在所述网框上。
本发明一种印刷网版，包括多条经线及多条纬线，所述经线及所述纬线以上下交错的方式进行编织，以形成多个开口，所述经线和/或所述纬线的表面凸凹不平。在利用所述印刷网版进行网版印刷，当通过所述开口灌入浆料时，所述浆料与所述开口周围的经线与纬线的接触面积增加。根据浆料的粘附力的特性：浆料接触的表面的面积越大，所述浆料与接触表面之间的粘附力越大。则，所述浆料与所述开口周围的经线与纬线的接触表面的粘附力越大，可使粘度较低的浆料粘附于所述网孔内，从而扩大了网版印刷的适用条件，实现了网版印刷对粘度较低的浆料的需求。
附图说明
为了更清楚地说明本发明的技术方案，下面将对实施方式中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施方式，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以如这些附图获得其他的附图。
图1是本发明第一实施方式提供的印刷网版的俯视图；
图2是本发明第一实施方式提供的印刷网版的部分截面图；
图3是本发明第二实施方式提供的印刷网版的俯视图；
图4是本发明第三实施方式提供的印刷网版的俯视图。
具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。
请参阅图1及图2，本发明较佳实施方式提供一种印刷网版100。所述印刷网版包括多条经线10及多条纬线20。所述经线10及所述纬线20以上下交错的方式进行编织，以形成多个开口30。所述经线10和/或所述纬线20的表面凸凹不平。
在本实施方式中，由于所述经线10和/或纬线20的表面凸凹不平，则在利用所述印刷网版100进行网版印刷，当通过所述开口30灌入浆料时，所述浆料与所述开口30周围的经线10与纬线20的接触面积增加。根据浆料的粘附力的特性：浆料接触的表面的面积越大，所述浆料与接触表面之间的粘附力越大。因此，本实施方式增大了所述浆料与所述开口30周围的经线与纬线20接触的表面积，所述浆料与所述开口30周围的经线与纬线20的接触表面的粘附力越大，可使粘度较低的浆料粘附于所述网孔30内，从而扩大了网版印刷的适用条件，实现了网版印刷对粘度较低的浆料的需求。
具体地，所述经线10和/或所述纬线20的表面呈凸凹不平。可选地，所述经线10和/或纬线20的表面呈锯齿状，也可以呈波浪状。该锯齿状及波浪状可以为不规则锯齿状及波浪状，即非周期性变化。对于所述经线10和/或所述纬线20的表面所呈现的凸凹不平的形状均在申请的保护范围内。在此不再进行一一列举。
在本实施方式中，所述经线10和所述纬线20的材质可以为不锈钢。所述开口30为正方形。在其他的实施方式中，所述经线10和所述纬线20的材质可以根据实际需要进行调整。
请参阅图2，本发明第二实施方式提供一种印刷网版200。所述第二实施方式提供的印刷网版200与所述第一实施方式提供的印刷网版100不同，两者的区别在于：在第二实施方式中，所述经线10与所述纬线20的每一个交错处被固定且分别形成一个网结40。
需要说明的是，目前的印刷网版中，由于其经线及纬线的交错部位并未固定，在精密印刷时容易因为刮刀施加的压力而产生位移的情形，进而影响到印刷的质量。因此，本实施方式中，所述进一步地，所述经线10与所述纬线20的每一个交错处被固定处理，使得进行精密印刷时因为所述经线10及所述纬线20的交错处未固定而导致的网版位移的情况得以获得改善。
进一步地，所述多个经线10的线径相同，且为第一线径b。所述多条纬线20的线径相同，且为第二线径c。所述网结40具有大于所述第一线径b以及所述第二线径c的第三线径d。
需要说明的是，所述印刷网版还包括网框。当所述经线10及所述纬线20以上下交错的方式进行编织形成网布后，将形成的网布固定于所述网框内(即所述以上下交错方式编织的经线10及纬线20固定在所述网框上)。将所述经线20与所述纬线30交错的部位分别进行固定以形成网结40。最后，在利用物理和化学沉积的方式，使得所述网结40的部分以及所述第一及第二线径b及c的宽度加宽。
其中，现有的印刷网版在印刷时也无法降低局部区域的透墨量，使得油墨、浆料等材料使用量增加，有无法突显预减少透墨量的区域，因此造成营运成本在无形中增加，且无法到达渐层印刷效果的情形。因此，本实施方式中，由于所述网结40经由物理或化学沉积的处理后其第一线径b、第二线径c及第三线径d均比未处理的经线及纬线的线径粗，使得所述开口30(亦即印刷网版的透墨口)的面积变小，印刷网版的透墨量变低，进而在印刷时达到改变印刷效果、降低油墨等材料的使用量，以及节省营运成本等效果。
请继续参阅图3，本发明第三实施方式提供一种印刷网版300。所述第三实施方式提供的印刷网版300与所述第二实施方式提供的印刷网版200相似，两者的区别在于：在第三实施方式中，所述经线10及所述纬线20以上下交错的方式进行编织形成网布，所述网布包括预设区域310及非预设区域。所述预设区域310内的印刷网版进行了沉积处理。即所述预设区域310内的经线311、纬线312及网结313的线径分别为第四线径、第五线径及第六线径。所述非预设区域内的经线10、纬线20及网结40的线径分别为第七线径、第八线径及第九线径。其中，所述第六线径大于所述第四线径及所述第五线径，第九线径 大于所述第七线径及第八线径，所述第四线径大于所述第七线径，所述第五线径大于所述第八线径，所述第六线径大于所述第九线径。因此，根据所述第三实施方式提供的印刷网版300，除了具有上述根据第一及第二实施方式印刷网版100及200的优点及特征外，还可在印刷时达到渐层印刷的效果。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
