Description
本申请要求于2019年01月29日提交中国专利局、优先权号为201920168823.3、发明名称为“反射片”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本申请涉及反射片领域，具体而言，涉及一种反射片。
现有的发射片大部分采用单色印刷，也即，反射率较高的区域和反射率较低的区域都是一次印刷同一种颜色的油墨，光线不容易控制，会造成亮暗过渡不均匀现象，造成整机品味无法完全达到客户需求，降低了产品的竞争力。另外，亮暗对应的边缘位置，都是印刷单色(黑色)油墨，因材料颜色的原因，无法完全避免亮暗过渡不均匀的现象。
针对上述的问题，目前尚未提出有效的解决方案。
发明内容
本申请实施例提供了一种反射片，以至少解决相关技术中单色印刷的方式会造成反射片亮暗过渡不均匀的技术问题。
根据本申请实施例的一个方面，提供了一种反射片，所述反射片包括第一印刷区和第二印刷区，其中，所述第一印刷区为反射率超过第一阈值的区域，所述第二印刷区为反射率低于第二阈值的区域，所述第一印刷区印刷第一颜色的油墨，所述第二印刷区印刷第二颜色的油墨。

可选的，所述第一印刷区和所述第二印刷区均为多个。
可选的，所述反射片还包括：过渡印刷区，所述过渡印刷区为反射率位于第一阈值与第二阈值之间的区域。
可选的，所述过渡印刷区的数量为多个。
可选的，所述过渡印刷区包括多种过渡分印刷区，多种所述过渡分印刷区分别对应的反射率均不相同。
可选的，每种所述过渡分印刷区均为多个。

可选的，所述第一阈值与所述第二阈值相等。
在本申请实施例中，采用对反射片的反射率不同的区域印刷不同的颜色的方式，通过印刷不同颜色使反射率不同的区域的反射率的差距减小，达到了使反射率不同的区域的反射率的变化更平缓的目的，从而实现了使反射片的亮暗均匀过渡的技术效果，进而解决了相关技术中单色印刷的方式会造成反射片亮暗过渡不均匀的技术问题。
此处所说明的附图用来提供对本申请实施例的进一步理解，构成本申请实施例的一部分，本申请的示意性实施例及其说明用于解释本申请，并不构成对本申请实施例的不当限定。在附图中：
图1是根据本申请实施例的一种反射片的示意图；
图2是根据本申请实施例的另一种反射片的示意图；
图3是根据本申请实施例的另一种反射片的示意图。
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
需要说明的是，本申请实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任 何变形，意图在于覆盖不排他的包含，例如，包含了一系列单元的系统、产品或设备不必限于清楚地列出的那些单元，而是可包括没有清楚地列出的或对于这些产品或设备固有的其它单元。
本申请实施例提供了一种反射片的实施例。
图1是根据本申请实施例的一种反射片的示意图，如图1所示，该反射片包括：
第一印刷区12和第二印刷区14，其中，第一印刷区12为反射率超过第一阈值的区域，第二印刷区14为反射率低于第二阈值的区域，第一印刷区12印刷第一颜色的油墨，第二印刷区14印刷第二颜色的油墨。
通过上述反射片，采用对反射片的反射率不同的区域印刷不同的颜色的方式，通过印刷不同颜色使反射率不同的区域的反射率的差距减小，达到了使反射率不同的区域的反射率的变化更平缓的目的，从而实现了使反射片的亮暗均匀过渡的技术效果，进而解决了相关技术中单色印刷的方式会造成反射片亮暗过渡不均匀的技术问题。
上述第一印刷区为反射率超过第一阈值的亮区域，在反射片上表现为反射率较高，亮度较亮，上述第二印刷区为反射率低于第二阈值的暗区域，在反射片上表现为反射率较低，亮度较暗。上述第二阈值不大于第一阈值，从而保证第一印刷区的反射率的范围与第二印刷区的反射率的范围不发生重叠，有效避免第一印刷区和第二印刷区的发射亮度相同的情况，印刷不同颜色的油墨会导致，上述第一印刷区和第二印刷区的反射率的差别更大。
上述第一印刷区的反射率为第一印刷区的平均反射率，由于第一印刷区的反射率可能不均匀，不规则。为了计算方便，本实施例中采用取第一印刷区的平均反射率作为第一印刷区的反射率。上述第二印刷区的反射率与第一印刷区的反射率可以以同样的方式确定。
在上述第二阈值小于上述第一阈值时，第一印刷区的反射率范围与第二印刷区的反射率范围距离较大，第一印刷区的明暗程度远亮于第二印刷区的明暗程度。在上述第二阈值等于上述第一阈值时，第一印刷区的反射率范围与第二印刷区的反射率范围距离较小，第一印刷区的明暗程度亮于第二印刷区的明暗程度，且第一印刷区和第二印刷区的明暗程度相近，但是还是有明显差别。
在上述第一印刷区印刷第一颜色的油墨，在第二印刷区印刷第二颜色的油墨。在上述第一印刷区和第二印刷区印刷不同颜色的油墨，第一印刷区本身的反射率和第二印刷区本身的反射率不同，利用不同颜色的油墨的反射率不同，对第一印刷区的反射率和第二印刷区的反射率进行补偿。在反射率较高的区域印刷反射率较低的油墨，在 反射率较低的区域印刷反射率较高的油墨，使反射率相差较大的第一印刷区和第二印刷区的反射率的差距缩小，或者相同。从而使第一印刷区和第二印刷区的明暗程度变化的更均匀平缓，有效改善第一印刷区和第二印刷区原有的明暗亮度差距过大，明暗过渡不均匀的情况。
本申请实施例还提供了另一种反射片，图2是根据本申请实施例的另一种反射片的示意图；如图2所示，需要说明的是，本实施例是在上述图1所示实施例的基础上具体细化，反射片的第一印刷区12与第二印刷区14相邻。
在第一印刷区的反射率与第二印刷区的反射率相差不变的情况下，上述第一印刷区与第二印刷区相邻，会使上述第一印刷区与第二印刷区的明暗差别更加明显。因此，更需要通过印刷不同颜色的油墨使第一印刷区与第二印刷区的明暗差别减弱。在第一印刷区与第二印刷区相邻的情况下，采用印刷不同颜色的油墨改善第一印刷区与第二印刷区的明暗程度变化的效果会更好。
可选的，第一颜色的反射率和第一印刷区的反射率之和，与第二颜色的反射率和第二印刷区的反射率之和相等。
在反射率较高的区域印刷反射率较低的油墨，在反射率较低的区域印刷反射率较高的油墨，使反射率相差较大的第一印刷区和第二印刷区的反射率的差距缩小，或者相同。在本实施例中，采用使反射率相差较大的第一印刷区和第二印刷区的反射率相同，让上述第一印刷区的反射率和第二印刷区的反射率相同，可以使第一印刷区和第二印刷区的亮度相同，以解决第一印刷区和第二印刷区的明暗程度变化明显的问题。
可选的，第一印刷区和第二印刷区均为多个。
在同一片反射片中，反射率大于第一阈值的第一印刷区可能不止一个，而且可能不连续。同理，第二印刷区也同样的可能不止一个，而且不连续。在第一印刷区和第二印刷区均为多个的情况下，对同为第一印刷区的区域印刷同一种颜色的油墨，对同为第二印刷区的区域印刷同一种颜色的油墨。
本申请实施例还提供了另一种反射片，图3是根据本申请实施例的另一种反射片的示意图；如图3所示，需要说明的是，本实施例是在上述图1所示实施例的基础上具体细化，可选的，反射片还包括：过渡印刷区32，过渡印刷区为反射率位于第一阈值与第二阈值之间的区域。
上述第一阈值大于所述第二阈值，如果第一阈值与第二阈值之间的差距过大，会导致第一印刷区与第二印刷区之间的过渡区域也存在差别较大的反射率，进而导致明暗程度变化较大的情况，因此，设置过渡印刷区，过渡印刷区为反射率位于第一阈值 与第二阈值之间的区域，在第一印刷区域第二印刷区之间作为缓冲。
可选的，过渡印刷区的数量为多个。
与上述第一印刷区和第二印刷区为多个的情况类似，上述过渡印刷区的数量为多个。对同为过渡印刷区的区域印刷同一种颜色的油墨。
可选的，过渡印刷区包括多种过渡分印刷区，多种过渡分印刷区分别对应的反射率均不相同。
在上述过渡印刷区的反射率跨度较大的情况下，可以将上述过渡印刷区划分为多个反射率不同的过渡分印刷区，划分的多种过渡分印刷区的反射率范围的总和为过渡印刷区的反射率范围，可以保证将过渡印刷区划分完毕，按照多个过渡分区域进行处理，从而防止过渡印刷区的发射率范围跨度较大，导致印刷效果差，对第一印刷区和第二印刷区的缓冲效果减弱的问题。
可选的，每种过渡分印刷区均为多个。
与上述第一印刷区、第二印刷区和过渡印刷区均为多个的情况类似，上述每种反射率范围相同的过渡分印刷区均可以为多个，对反射率范围相同的过渡分印刷区印刷同一种颜色的油墨。
可选的，每种过渡分印刷区印刷的颜色的反射率，与所述过渡分印刷区的反射率之和均相等。
与上述第一颜色的反射率和第一印刷区的反射率之和，与第二颜色的反射率和第二印刷区的反射率之和相等的情况类似，每种过渡分印刷区印刷的颜色的反射率，与所述过渡分印刷区的反射率之和均相等。
可选的，第一阈值与第二阈值相等。
在第一印刷区域第二印刷区的明暗程度差别较小时，存在上述第一阈值与第二阈值相等的情况。
上述本申请实施例序号仅仅为了描述，不代表实施例的优劣。
在本申请的上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上所述仅是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请实施例的保护范围。
