Description

防伪元件及防伪产品 技术领域
本发明涉及防伪领域，具体地，涉及一种防伪元件及防伪产品。
背景技术
绝大部分有价文件包含磁性材料的防伪元件，比如磁性图标、磁性防伪线或防伪条。磁性材料可连续地或在一些区域施加到防伪元件，例如以磁性图标或磁性编码的形式。
为了提高防伪元件的防伪水平，专利申请CN102971748A提出了使用两种或两种以上的矫顽力材料形成磁性代码区的方法，其中两种材料形成的磁性单元虽然对磁性编码具有一定的隐蔽性并且具有较高的防伪性能，但是两种材料的印刷套印的生产难度很高，并且该防伪元件需要专用的检测设备才能进行识别。
发明内容
本发明的目的是提供一种防伪元件及防伪产品，其中防伪元件对磁性编码具有较好的隐蔽性而且防伪性能高。印刷制作不需要高精度套印，制作更简单，而且通用检测设备就可以识别。
为了实现上述目的，本发明提供一种防伪元件，包括：基材；以及位于所述基材上的一个或多个磁性单元，所述一个或多个磁性单元中至少第一磁性单元所产生的磁码测量宽度小于该第一磁性单元的视觉宽度。
可选地，所述一个或多个磁性单元由一种磁性材料制成。

相应地，本发明还提供一种防伪产品，包括上述的防伪元件。
通过上述技术方案，在防伪元件中至少有一个磁性单元所产生的磁码测量宽度小于该磁性单元的视觉宽度，通过该特征可以很容易检测出防伪元件的真伪，提高了防伪元件的防伪性能并且对磁性编码具有很好的隐蔽性，同时易于批量化生产，采用例如市场通用的验钞机就可以识别。
本发明的其它特征和优点将在随后的具体实施方式部分予以详细说明。

具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。并且，本领域技术人员应当理解，所有附图中的灰度以及尺寸比例仅为示意性的，不代表实际的颜色和尺寸比例。
在本发明的实施例中所提到的“第一”及“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。
本发明实施例提供一种防伪元件，该防伪元件可以包括：基材；以及位于该基材上的一个或多个磁性单元，所述一个或多个磁性单元中至少第一磁性单元所产生的磁码测量宽度小于该第一磁性单元的视觉宽度。在对防伪元件进行机读时可以得到对应于磁性单元的脉冲信号，这里，机读是指利用磁性传感器等装置对防伪元件进行检测。脉冲信号对应于磁性单元中能够产生脉冲信号的区域的边缘的波峰与波谷之间的距离定义为磁码测量宽度，本发明实施例提供的防伪元件中至少存在一个磁性单元，该磁性单元所对应的磁码测量宽度小于该磁性单元的视觉宽度，进而使得脉冲信 号不会依赖于防伪元件的外观特征而被再现，进而提高了防伪元件的防伪性能，并且该防伪元件的防伪性能易于检测例如采用市场通用的验钞机就可以识别防伪元件的真伪，同时该防伪元件的生产难度低，易于批量化生产。
可选地，所述一个或多个磁性单元可以由一种材料制成，该材料例如可以是导电油墨。磁性单元由一种材料制成，因而可以通过一次印刷完成，制作工艺简单，很大程度上减少了防伪元件的生产难度及制作成本。
可选地，可以通过控制磁性单元不同区域的含墨量来实现磁码测量宽度小于磁性单元的视觉宽度。在对防伪元件进行机读时，机读可识别区域的宽度仅与含磁量大的部分的区域的宽度相同，因此，可以通过设置磁性单元中至少有一区域的含磁量大于其余区域的含磁量来实现磁码测量宽度小于磁性单元的视觉宽度。
磁性单元可以是以下中的一者或多者：字母、数字、文字和/或图案等。可选地，磁性单元可以周期或非周期地排列于基材上。
图1示出了以字母“B”示例的磁性单元的示意图。如图1所示，字母“B”的左侧部分的含磁量大于右侧部分的含测量，但是在视觉效果上字母“B”整体均匀不透光。在以箭头方向对字母“B”进行机读时，所产生的磁码测量宽度c1小于字母“B”的视觉宽度a1。应当理解，这里字母“B”仅用于示例，并不用于限制本发明。
图2(a)分别示出了现有技术和本发明实施例的由字母和数字组成的磁性单元的示意图。如图2(a)所示，字母201和数字202是两个由现有技术制作的磁性单元，字母203和数字204是本发明实施例提供的磁性单元，从图2(a)中可以看出字母201和字母203具有相同的视觉效果，字数字202和数字204具有相同的视觉效果。
图2(b)示出了图2(a)所示的磁性单元沿虚线及箭头方向的剖面图。剖面图211和212表明，使用现有技术制作的字母201和数字202的各区 域的含磁量相同，其在制作过程采用了同一种磁墨并具有相同的制版参数。而剖面图213和214中的深色区域和浅色区域采用了不同的制版设计，在深色区域中具有较大的磁墨填充量，浅色区域具有较少的磁墨填充量，仅在外观上与深色区域保持一致。在对磁性单元进行机读时，仅深色区域能够产生机读脉冲信号。
图2(c)示出了图2(a)所示的磁性单元的机读信号示意图。沿图中箭头方向对磁性单元进行机读时，使用现有技术制作的字母201和数字202产生脉冲信号221和222，脉冲信号221的磁码测量宽度a2与字母201宽度相同，脉冲信号222的磁码测量宽度b2与数字202宽度相同。本发明实施例提供的磁性单元的字母203和数字204产生脉冲信号223和224，脉冲信号223的磁码测量宽度c2小于字母203的宽度而与剖面图213中深色区域的宽度相同，脉冲信号224的磁码测量宽度d2小于数字204的宽度而与剖面图214中深色区域的宽度相同。本发明实施例提供的磁性单元所产生的脉冲信号更适宜机读。
图3(a)分别示出了现有技术和本发明实施例的由心形图案组成的磁性单元的示意图。图3(a)中心形图案31、32、33、34大小形状相同，心形图案31和32是采用公知技术制作的磁性单元，心形图案33、34是本发明实施例提供的磁性单元。
图3(c)示出了图3(a)的磁性单元的机读信号示意图，如图3(c)所示，沿图中箭头方向对磁性单元进行机读时，心形图案31和32产生的脉冲信号的磁码测量宽度等于心形图案31和32的宽度e，心形图案31和32产生的脉冲信号的磁码测量宽度分别是f和g，小于心形图案31和32的宽度e。本发明实施例提供的心形图案33、34所产生的磁码测量宽度f和g可以根据心形图案中含磁量大的部分的区域宽度的变化而变化。
图3(b)示出了采用现有技术制作的条块状磁码的示意图，图3(c)示出了图3(b)的条状磁码的机读信号示意图。图3(b)的各条块状磁码 所产生的机读信号与图3(a)中各心形图案所产生的机读信号对应相同。但是在实际应用中，例如应用于制作细长安全线时，图3(a)能够同时提供视觉防伪特征和机读防伪特征，而图3(b)的外观观赏性较差，更适宜仅提供机读防伪特征。针对该图3(b)的一个示例应用可以是通过金属层或通过不透明墨层将图3(b)所示的条块状磁码隐藏在安全文件中，例如在欧元和英镑的安全线中的应用方式。
图4(a)示出了面积较大的磁性单元的示意图。图4(b)示出对采用现有技术制作的图4(a)所示的磁性单元沿箭头所示方向进行机读时所产生的脉冲信号，从图中可看出，脉冲信号中杂峰较多，不利于定量机读。图4(c)示出对如图4(a)所示的本发明实施例的磁性单元沿箭头所示方向进行机读时所产生的脉冲信号，脉冲信号由含磁量较大的区域形成，从图中可看出，脉冲信号的峰值间隔清晰，适用于定量机读。
图5示出了本发明实施例提供的防伪元件应用于磁图标的示意图。如图5所示，本发明实施例提供的防伪元件应用于磁图标时可以同时提供视觉防伪特征和机读防伪特征。
图6示出了本发明实施例提供的防伪元件应用于安全线的示意图。如图6所示，磁性单元可周期性地排列于基材之上，图中字母和数字类型的磁性单元仅用于示例，并不用于限制本发明。所述安全线可以是细长形状的安全线，安全线作为防伪元件植入纸张。所述安全线也可以直接印刷在安全文件的基材上。从图中可知本发明实施例提供的防伪元件应用于安全线时也可以同时提供视觉防伪特征和机读防伪特征。
图7示出了本发明实施例提供的防伪元件以隐藏方式应用于安全线的结构示意图。如图7所示，在该安全线的结构示意图中，在防伪元件的磁性单元层之上覆盖有第一遮盖层，在防伪元件的磁性单元层下方覆盖有第二遮盖层，并通过第一粘结胶和第二粘结胶粘附在各种物品上，如钞票等。在图7的示例中第二遮盖层覆盖于基材的上方，但是应当理解，根据具体 应用的不同或者根据实际应用的需求，该第二遮盖层也可以覆盖于基材的下方。这里，所述第二遮盖层例如可以为金属镀层或者遮盖墨，但是本发明并限制于此。
本发明提供的防伪元件可以用于制作安全线、宽条、标签、标识等，也可以直接印刷在安全文件上或通过各种粘结机理粘附在各种物品上，例如印刷在塑料钞或转移到钞票、信用卡等高安全产品和高附加值产品上。
本发明另一方面提供了一种包括有上述防伪元件的防伪产品，可选地，防伪元件可以全埋或开窗方式设置于所述防伪产品中。所述防伪产品包括但不限于以下中的一种：钞票、银行票据、门票、证件、文件或信用卡等。
本发明实施例提供的防伪元件制作工艺简单、防伪性能高，并且可以更好地集成在有价文件的设计中，作为有价文件图形设计的一部分。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，这些简单变型均属于本发明的保护范围。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合，为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。
此外，本发明的各种不同的实施方式之间也可以进行任意组合，只要其不违背本发明的思想，其同样应当视为本发明所公开的内容。
