具体实施方式
为使本领域技术人员更好的理解本发明实施例的技术方案，下面结合附图和具体实施方式对本发明作详细说明。
请参考图1及图4，本发明实施例提供了一种标识制作方法，其包括如下步骤：在基体1上形成预定形状的基底图案3；在基底图案3上形成色彩层；其中，色彩层包括多个子色彩层，每个子色彩层的自身的颜色相同且至少两个子色彩层的颜色不相同，多个子色彩层拼接成色彩层，色彩层形成与基底图案3相同的图案，且色彩层形成的图案覆盖基底图案3。需要说明的是，本文中所指出的色彩层、子色彩层、叠加层及PU层(或UV层)的结构并非为限定在一个完整的平面结构，而是指具有一定的形状轮廓的以形成图案的“层”，即单独形成图案基层3中的部分图案或图案基层3的整个图案。
具体的，如图1及图4所示，在本发明的标识制作方法的第一实施例中，色彩层仅包括第一子色彩层40和第二子色彩层41，即在基底图案3上只形成有第一子色彩层40和第二子色彩层41，其中，由于在基底图案3上无法单次形成非单一颜色的图案，因此，形成色彩层的具体步骤包括：在基底图案3上形成第一子色彩层40，在基底图案3上形成第二子色彩层41；需要说明的是，形成第一子色彩层40和形成第二子色彩层41并没有特定的顺序，可根据实际制作情况对两者的形成顺序做相应调整。另外，为了更好的表达出第一子色彩层40及第二子色彩层41的真实色彩，基底图案3的颜色为白色，其至少能够防止基体1的颜色对第一子色彩层40及第二子色彩层41造成不良影响；另外，形成基底图案3的材质应具备良好的耐久性及化学稳定性等，从而能够保证色彩层稳固的(间接)形成在基体1上。
进一步的，如图2所示，本发明的标识制作方法的第二实施例，该方法具体包括：在基体1上形成背景层2，其中，可以将背景层2覆设基体1的一部分表面或整个表面，然后在背景层2上形成基底图案3，在形成的基底图案3上形成第一子色彩层40、第二子色彩层41，然后在第二子色彩层41上形成叠加层42以形成色彩层，最后在形成的色彩层上形成PU(本实施例中以PU层为例对本申请技术方案进行具体说明)(polyurethane)层5。具体的，背景层2的形成一方面可以提升基体1的整体外观颜色，还能对基体1形成保护作用，防止基体1被氧化等，另一方面还能够与形成的色彩层的颜色相呼应，提升基体1整体色彩感受；另外，为了进一步的提升色彩层的色彩表现能力，本实施例中，在形成第二子色彩层41后又在其表面形成有叠 加层42，其中，第二子色彩层41与叠加层42的颜色相同，从而增加了第二子色彩层41(叠加层42)的色彩表现能力，进一步降低了基底图案3和/或背景层2对其色彩表现所产生的影响。进一步的，聚氨基甲酸酯为一种新兴的有机高分子材料，其具有重量轻、弹性好、耐磨损、耐腐蚀等特点，因此，在本实施例中，在形成的色彩层上形成有水性聚氨酯涂料层，从而能够防止色彩层受到外界的磨损，另外，形成的PU层5表面光滑且具有较高的透光性，因此还能实现高亮的视觉效果，从而能够提高色彩层的表现效果。
请参阅图3至图8，以下以该基体1为电子设备的壳体、该色彩层形成logo为例进行具体说明：
首先在壳体外表面喷涂外观漆层，其中，壳体的材质可以为合金、碳纤维等，外观漆层可以为弹性漆以提供良好的手感，本实施例中，壳体采用碳纤维材质，且外观漆层为深黑色皮革漆(丙烯酸酯树脂)，因此，能够提升用户的触觉体验。当然在其他实施例中，壳体还可以采用镁合金、铝合金等材质，在进行喷漆(形成外观漆)处理之前，其表面可以进行喷砂、拉丝等处理工艺；另外，外观漆层的颜色可根据不同设计需求做多样性调整，本实施例在此不做具体限定。
进一步的，为了提升将要形成的色彩层的表现力，形成外观漆层后，形成基底图案3；本实施例中，采用钢板印刷工艺将基底图案3印制在外观漆层上，且考虑到第一子色彩层40及第二子色彩层41的颜色特点，形成的基底图案3优选为白色，当然在其他实施例中，为了根据实际情况更好的衬托第一子色彩层40及第二子色彩层的颜色表现，基底图案的颜色还可以为灰白色、浅灰色、黄色、银色等浅色系的颜色，本实施例在此不做具体限定；接着采用钢板印刷工艺在基底图案3上印制第一子色彩层40，如图6所示，本实施例中的logo的造型为X1，因此，基底图案3也为X1的造型；其中，第一子色彩层40包括logo中的X的右半部分及1，且第一子色彩层40的颜色为黑色，由于第一子色彩层40形成在外表较为光滑的基底图案3上，因此，第一子色彩层40的色彩表现为亮黑色，与壳体的哑光黑色高度融合的同时又有所不同；进一步的，为了实现logo的多色效果，在形成第一子色彩层40之后或之前(当然，如果工艺条件允许，第一子色彩层40与第二子色彩层41的形成也可以同时进行)，采用钢板印刷工艺在基底图案3上印制第二子色彩层41，如图7所示，本第二子色彩层41包括logo中的X的左半部分， 且第二子色彩层41的颜色为红色；进一步的，如图8所示，在本发明提供的实施例中，为了凸显logo的红色部分，在形成第二子色彩层41之后，在第二子色彩层41上采用钢板印刷工艺印制有叠加层42，其中，叠加层42与第二子色彩层41的色彩相同，最后在形成的色彩层上形成有PU层5，其中，PU层5可以与色彩层的形状及大小相同，且PU层5形成有两层，从而使得logo部分形成高亮的表面，以提升logo的视觉效果及辨识度，另外，在其他实施例中，所形成的PU层5的面积可以大于logo的面积，其形状也可根据实际情况做相应调整。需要说明的是，本实施例中仅仅示出了，色彩层包括第一子色彩层40、第二子色彩层41及叠加层42的情况，且第一子色彩层40与第二子色彩层41、叠加层42相邻，所形成的第一子色彩层40的厚度与第二子色彩层41、叠加层42叠加的厚度几乎相同，当然在其他实施例中，第一子色彩层40与第二子色彩层41之间也可以保持一定的距离，另外，色彩层中所包含的子色彩层的数量可以为多个，且多个子色彩层的位置排布及形状、大小可根据不同情况做相应调整，本实施例在此不做具体限定。
另外，本发明实施例还提供了一种壳体，其包括基体1，基体1的预定区域设有基底图案3，基底图案3上设有色彩层，色彩层包括多个子色彩层，每个子色彩层的自身的颜色相同且至少两个子色彩层的颜色不相同，多个子色彩层拼接成色彩层。
进一步的，色彩层上设有PU层5。其中，壳体可以为笔记本电脑的外壳也可以为智能手机等电子设备的外壳；具体的，如图4所示，在本发明提供的壳体中包含基体1、位于基体1上的基底图案3、位于基底图案3上的色彩层及位于色彩层上的PU层5，其中，色彩层包括第一子色彩层40、第二子色彩层41及叠加层42；如图6至图8所示，其中，第一子色彩层40与第二子色彩层41相邻设置，叠加层42与第二子色彩层41的形状及颜色相同，且位于第二子色彩层41上(第一子色彩层40、第二子色彩层41及叠加层42的具体参数可参照上述标识制作方法中的描述，在此不做赘述)，本实施例中，PU层5设置有两层，且依次设置在色彩层上，以对色彩层形成保护、提升视觉效果等作用，其中第一子色彩层40与第二子色彩层41之间也可以保持一定的距离，另外，色彩层中所包含的子色彩层的数量可以为多个，且多个子色彩层的位置排布及形状、大小可根据不同情况做相应调整，本实施例在此不做具体限定。
以上实施例仅为本发明的示例性实施例，不用于限制本发明，本发明的保护范围由权利要求书限定。本领域技术人员可以在本发明的实质和保护范围内，对本发明做出各种修改或等同替换，这种修改或等同替换也应视为落在本发明的保护范围内。
