Description

多光彩光变印刷装置及其印刷方法、可读存储介质
本申请要求于2022年04月22日提交到中国国家知识产权局、申请号为“202210429178.2”、申请名称为“多光彩光变印刷装置及其印刷方法、可读存储介质”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。
技术领域
本申请涉及防伪印刷技术领域，具体而言，涉及一种多光彩光变印刷装置及其印刷方法、可读存储介质。
背景技术
光彩光变技术是指光变磁性油墨经丝网印刷及磁定向工艺后而产生动感光变现象的技术。目前，针对同一个丝网印刷图案，世界范围内的印刷设备只能实现单一效果的光彩光变技术，即实现单一磁场作用下的滚动效果，或实现复合磁场作用下的变化效果，尚无同时实现两种或两种以上效果的多光彩光变技术。
发明内容
本申请旨在至少解决现有技术或相关技术中存在的技术问题之一。
有鉴于此，本申请的第一目的在于提供一种多光彩光变印刷装置。
本申请的第二目的在于提供一种多光彩光变印刷方法。
本申请的第三目的在于提供一种多光彩光变印刷装置。
本申请的第四目的在于提供一种可读存储介质。
为了实现上述目的，本申请第一方面的技术方案提供了一种多光彩光变印刷装置，包括：输送单元，用于输送承印物；丝网印刷单元，用于在承印物上印刷含有磁性物质的油墨或清漆；以及多个光彩光变图案形成单元，多个光彩光变图案形成单元分别用于在承印物的不同区域形成光彩光变图案，每个光彩光变图案形成单元包括：磁化滚筒，磁化滚筒上设置有磁定向构件，磁 定向构件用于对承印物进行磁定向；以及预干燥固化器，预干燥固化器用于对承印物进行预干燥固化；其中，输送单元、丝网印刷单元以及多个光彩光变图案形成单元在承印物的输送方向上依次设置；其中，至少两个光彩光变图案形成单元的磁定向构件具有彼此不同的磁化效果，预干燥固化器在磁定向构件外侧相对设置，在磁定向构件对承印物进行磁定向的过程中，预干燥固化器同时对承印物进行预干燥固化；并且其中，预干燥固化器包括光学掩膜固化装置，光学掩膜固化装置固定设置，用于投射出动态可刷新的可变光场图文，可变光场图文与承印物同步运动预定距离。
根据本申请提供的多光彩光变印刷装置，包括输送单元、丝网印刷单元和多个光彩光变图案形成单元。输送单元用于输送承印物，丝网印刷单元位于输送单元的下一道工序，用于将由输送单元输送过来的承印物上压印含有磁性物质的油墨或清漆，形成半成品。多个光彩光变图案形成单元位于丝网印刷单元的下一道工序，用于在半成品上形成光彩光变图案。光彩光变图案形成单元包括磁化滚筒和预干燥固化器，磁化滚筒上设置有磁定向构件，磁定向构件用于对承印物进行磁定向，预干燥固化器用于对承印物进行预干燥固化。其中，至少两个光彩光变图案形成单元的磁定向构件具有彼此不同的磁化效果，预干燥固化器在磁定向构件外侧相对设置，在磁定向构件对承印物进行磁定向的过程中，预干燥固化器同时对承印物进行预干燥固化。预干燥固化器包括光学掩膜固化装置，光学掩膜固化装置用于投射出动态可刷新的可变光场图文，可变光场形成的图文照射到磁化滚筒上的承印物上，与承印物同步运动，承印物上的油墨或清漆完成预干燥，从而能够完成固定式和可变式的多光彩光变图文的全向拼接，即任意方向拼接。光学掩膜固化装置固定设置。需要说明的是，“固定设置”是指在产品确定后的连续生产过程中光学掩膜固化装置固定，当产品规格变化时可以沿磁化滚筒的轴向方向移动光学掩膜固化装置，以适用不同产品的规格。通过设置不同磁场效果的磁定向构件和能够实现精准固化的光学掩膜固化装置作为预干燥固化器，从而实现针对同一个丝网印刷图案的多个区域，分别实现多种光彩光变效果，实现多种固定效果图文的全向拼接，也能实现可变效果图文与固定效果图文的全向拼接。多种效果可以是多种单一磁场作用下的滚动效果，也可以是多种复合磁场 作用下的运动效果，还可以是单一磁场作用下的滚动效果和复合磁场作用下的运动效果。
其中，在承印物随着磁化滚筒同步运动的同时，即承印物被持续磁化的过程中，光学掩膜固化装置能够投射出高刷新率的运动图文，控制系统通过传感器，如旋转编码器、光栅尺等，采集承印物或输送装置或磁化滚筒的位置和速度，控制光学掩膜固化装置投射的图文与承印物同步运动，光学掩膜固化装置机械本体是不动的。
可以理解，由于油墨中的OVMP颜料片与承印物之间形成一定的夹角的原理，光变磁性油墨中的OVMP颜料片预固化或固化或自然渗透干燥之前，对OVMP颜料片的磁定向作用始终有效，所以在此期间可以进行两次或多次磁定向，从而可以实现在同一个丝网印刷图案，实现两种以上效果的多光彩光变技术。

在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图9描述根据本申请的一些实施例。
如图1所示，根据本申请提出的一个实施例的多光彩光变印刷装置10，包括：输送单元100，用于输送承印物500；丝网印刷单元110，用于在承印物500上印刷含有磁性物质的油墨或清漆；以及多个光彩光变图案形成单元，多个光彩光变图案形成单元分别用于在承印物500的不同区域形成光彩光变图案，每个光彩光变图案形成单元包括：磁化滚筒130，磁化滚筒130上设置 有磁定向构件132，磁定向构件132用于对承印物500进行磁定向；以及预干燥固化器160，预干燥固化器160用于对承印物500进行预干燥固化；其中，输送单元100、丝网印刷单元110以及多个光彩光变图案形成单元在承印物500的输送方向上依次设置；其中，至少两个光彩光变图案形成单元的磁定向构件132具有彼此不同的磁化效果，预干燥固化器160在磁定向构件132外侧相对设置，在磁定向构件132对承印物500进行磁定向的过程中，预干燥固化器160同时对承印物500进行预干燥固化；并且其中，预干燥固化器160包括光学掩膜固化装置230，光学掩膜固化装置230固定设置，用于投射出动态可刷新的可变光场图文，可变光场图文与承印物500同步运动预定距离。
根据本申请提供的多光彩光变印刷装置10，包括输送单元100、丝网印刷单元110和多个光彩光变图案形成单元。输送单元100用于输送承印物500，丝网印刷单元110位于输送单元100的下一道工序，用于将由输送单元100输送过来的承印物500上压印含有磁性物质的油墨或清漆，形成半成品。多个光彩光变图案形成单元位于丝网印刷单元110的下一道工序，用于在半成品上形成光彩光变图案。光彩光变图案形成单元包括磁化滚筒130和预干燥固化器160，磁化滚筒130上设置有磁定向构件132，磁定向构件132用于对承印物500进行磁定向，预干燥固化器160用于对承印物500进行预干燥固化。其中，至少两个光彩光变图案形成单元的磁定向构件132具有彼此不同的磁化效果，预干燥固化器160在磁定向构件132外侧相对设置，在磁定向构件132对承印物500进行磁定向的过程中，预干燥固化器160同时对承印物500进行预干燥固化。预干燥固化器160包括光学掩膜固化装置230，光学掩膜固化装置230用于投射出动态可刷新的可变光场图文，可变光场形成的图文照射到磁化滚筒130上的承印物500上，与承印物500同步运动，承印物500上的油墨或清漆完成预干燥，从而能够完成固定式和可变式的多光彩光变图文的全向拼接，即任意方向拼接。光学掩膜固化装置230固定设置，即在产品确定后连续生产过程中光学掩膜固化装置230固定。需要说明的是，“固定设置”是指在产品确定后的连续生产过程中光学掩膜固化装置230固定，当产品规格变化时可以沿磁化滚筒130的轴向方向移动光学掩膜固化装置230，以适用不同产品的规格。通过设置不同磁场效果的磁定向构件132和能够实现 精准固化的光学掩膜固化装置230作为预干燥固化器160，从而实现针对同一个丝网印刷图案的多个区域，分别实现多种光彩光变效果，实现多种固定效果图文的全向拼接，也能实现可变效果图文与固定效果图文的全向拼接。多种效果可以是多种单一磁场作用下的滚动效果，也可以是多种复合磁场作用下的运动效果，还可以是单一磁场作用下的滚动效果和复合磁场作用下的运动效果。其中，墨或清漆可以是光彩光变油墨、固化光油或其他类型的UV固化油墨。承印物500可以是纸张、塑料片或金属片。
具体地，在承印物500随着磁化滚筒130同步运动的同时，即承印物500被持续磁化的过程中，光学掩膜固化装置230能够投射出高刷新率的运动图文，控制系统通过传感器，如旋转编码器、光栅尺等，采集承印物500或输送装置或磁化滚筒130的位置和速度，控制光学掩膜固化装置230投射的图文与承印物500同步运动，光学掩膜固化装置230机械本体是不动的。
可以理解，由于油墨中的OVMP颜料片与承印物500之间形成一定的夹角的原理，光变磁性油墨中的OVMP颜料片预固化或固化或自然渗透干燥之前，对OVMP颜料片的磁定向作用始终有效，所以在此期间可以进行两次或多次磁定向，从而可以实现在同一个丝网印刷图案，实现两种以上效果的多光彩光变技术。
如图5和图6所示，进一步地，多光彩光变印刷装置10包括传感器，传感器用于采集承印物500的位置信息和速度信息。光学掩膜固化装置230包括光源232、控制器234、透镜236和空间光调制器238。控制器234用于接收传感器的位置信息和速度信息，还用于接收、存储、处理投射用图文数据，并且基于位置信息和速度信息及投射用图文数据产生控制信号。空间光调制器238用于接收光源232发射的光以及控制信号，以通过透镜236投射出可变光场图文。空间光调制器238可以是数字微反镜DMD、液晶空间光调制器(SLM)或声光调制器(AOM)和GLV调制器。其中，DMD是Digital Micromirror Device的简称，SLM是Spatial Light Modulator的简称，AOM是Acousto Optical Modulator的简称，GLV是Grating Light Valve的简称。具体地，承印物500被持续磁化的过程中，光学掩膜固化装置230 能够投射出高刷新率的运动图文，控制系统通过传感器采集承印物500的位置信息和速度信息，控制光学掩膜固化装置230投射的图文与承印物500同步运动。光学掩膜固化装置230的同步投射控制方法解决了承印物500连续生产的问题，即承印物500在连续高速运动中完成图案的磁化定向及精准固化，可以使投射图文与承印物500已有印刷图案精确套准。
进一步地，光学掩膜固化装置230还包括散热组件240。散热组件240用于对空间光调制器238进行散热或对光源232进行散热。
具体地，光学掩膜固化装置230的数量可以为多个，多个光学掩膜固化装置230在磁化滚筒130的轴向方向上间隔设置，按照承印物500幅面大小，光学掩膜固化装置230可以组合使用。
在上述实施例中，可变图文可以是图形、文字、数字、冠字号码、条形码、二维码等任意图文。
如图2和图3所示，在上述实施例中，预干燥固化器160还包括固化装置调整机构，固化装置调整机构包括固定横梁210、电机220和导轨，固定横梁210沿磁化滚筒130的轴向方向延伸，光学掩膜固化装置230设于固定横梁210上，电机220驱动光学掩膜固化装置230沿固定横梁210移动，从而调整光学掩膜固化装置230的间隔距离。固定横梁210包括横板和竖板，横板和竖板相连，电机220设于横板上。导轨包括直线导轨250和固化装置导轨，直线导轨250设于横板上，固化装置导轨设于竖板上，多个光学掩膜固化装置230分别与直线导轨250相连，从而能够在固定横梁210上移动。
在上述实施例中，多光彩光变印刷装置10还包括传递系统380，传递系统380包括多个传送滚筒，用于将承印物500在输送单元100、丝网印刷单元110、多个光彩光变图案形成单元、以及下文将描述的可选的干燥固化单元370上依次传送。
如图4所示，在一些实施例中，多光彩光变印刷装置10还包括第一重排磁化装置280和第二重排磁化装置290。第一重排磁化装置280设于丝网印刷单元110与光彩光变图案形成单元之间，第二重排磁化装置290设于多个光彩光变图案形成单元之间。可以理解，承印物500从丝网印刷单元110行 进到第一重排磁化装置280后，才进入第一个光彩光变图案形成单元，然后从第一个光彩光变图案形成单元经过第二重排磁化装置290才进入第二个光彩光变图案形成单元。在承印物500上印刷油墨或清漆时，里面的磁性颜料片呈杂乱无规则排列，当这样的承印物500输送至第一重排磁化装置280和第二重排磁化装置290时，磁性颜料片被按照一定的规律重新排列，如平行于承印物500排列，由此能提高磁性颜料片经磁化滚筒130时，磁化定向的一致性，从而使得光彩光变效果更加明亮。
在上述实施例中，多光彩光变印刷装置10还包括干燥固化单元370，干燥固化单元370设置在多个光彩光变图案形成单元下游，用于对承印物500进行干燥固化。
如图8所示，本申请第二方面的实施例提供了一种多光彩光变印刷方法，包括：
步骤S102：通过丝网印刷单元在承印物上印刷含有磁性物质的油墨或清漆，形成半成品；
步骤S104：将半成品依次输送至多个光彩光变图案形成单元，通过光彩光变图案形成单元的磁定向构件和预干燥固化器对半成品进行磁定向的同时进行预干燥固化，以在承印物的不同区域形成光彩光变图案，从而形成多次光变产品；
其中，至少两个光彩光变图案形成单元的磁定向构件具有彼此不同的磁化效果，预干燥固化器包括光学掩膜固化装置，光学掩膜固化装置固定设置，用于投射出动态可刷新的可变光场图文，可变光场图文与承印物同步运动预定距离。
在该实施例中，首先在承印物上印刷含有磁性物质的油墨或清漆，形成半成品，然后依次通过多个光彩光变图案形成单元，通过磁定向构件和预干燥固化器对半成品进行磁定向的同时进行预干燥固化，以在承印物的不同区域形成光彩光变图案，从而形成多次光变产品。其中，至少两个光彩光变图案形成单元的磁定向构件具有彼此不同的磁化效果，预干燥固化器包括光学掩膜固化装置，光学掩膜固化装置用于投射出动态可刷新的可变光场图文，可变光场图文与承印物同步运动，从而实现针对同一丝印图文的两次或多次 磁化定位和预固化干燥，完成固定式和可变式的多光彩光变图文的全向拼接，即任意方向拼接。
如图9所示，根据上述实施例提供的多光彩光变印刷方法，还包括以下步骤：
步骤S202：在将半成品依次输送至多个光彩光变图案形成单元之后将多次光变产品输送至干燥固化单元进行干燥固化。
在该实施例中，在将半成品依次输送至多个光彩光变图案形成单元之后，将多次光变产品输送至干燥固化单元进行干燥固化，从而得到最终产品。
在上述实施例中，光学掩膜固化装置包括光源、控制器、透镜和空间光调制器。控制器用于接收传感器的位置信息和速度信息，控制器还用于接收、存储、处理投射用图文数据，并且基于位置信息和速度信息及所投射用图文数据产生控制信号。空间光调制器用于接收光源发射的光以及控制信号，以通过透镜投射出可变光场图文。空间光调制器可以是数字微反镜DMD、液晶空间光调制器(SLM)、声光调制器(AOM)和GLV调制器。具体地，承印物被持续磁化的过程中，光学掩膜固化装置能够投射出高刷新率的运动图文，控制系统通过传感器采集承印物的位置信息和速度信息，控制光学掩膜固化装置投射的图文与承印物同步运动。光学掩膜固化装置的同步投射控制方法解决了承印物连续生产的问题，即承印物在连续高速运动中完成图案的磁化定向及精准固化，可以使投射图文与承印物已有印刷图案精确套准。
如图7所示，本申请第三方面的实施例提供了一种多光彩光变印刷装置10，包括：存储器300和处理器400，其中，存储器300上存储有可在处理器400上运行的程序或指令，处理器400执行程序或指令时实现第二方面的实施例中任一项的多光彩光变印刷方法的步骤，故而具有上述第二方面任一实施例的技术效果，在此不再赘述。
本申请第四方面的实施例提供了一种可读存储介质，其上存储有程序或指令，程序或指令被处理器执行时实现第二方面的实施例中任一项的多光彩光变印刷方法的步骤，故而具有上述第二方面任一实施例的技术效果，在此 不再赘述。
如图1至图9所示，根据本申请提出的一个具体实施例的多光彩光变印刷装置10，包括输送单元100、丝网印刷单元110、磁化滚筒130、磁定向构件132、预干燥固化器160和光学掩膜固化装置230。其中，片状基材通过输送单元100被输送至丝网印刷单元110，通过丝网印刷将片状基材上压印油墨或清漆载体以形成承印物500。承印物通过传送滚筒输送至磁化滚筒130，承印物500上的油墨或清漆载体被磁化定位的同时，通过与磁化滚筒130相对设置的预干燥固化器160的光学掩膜固化装置230发出的可变光场形成的图案可对磁化后的部分油墨或清漆载体进行精确可变的预干燥固化。为了增加预干燥固化时间，可变光场的图文要跟随承印物500同步运动。由于预干燥固化器160是固定的，就需要图案可以投射面积内移动。由于投射面积的限制，可变光场的图文随旋转方向一开始可以是部分的，然后是完整图形，然后是部分图形。在承印物经两次或多次磁化并预干燥固化后，通过传送滚筒被输送至干燥固化单元370进行干燥固化，以形成印刷物。

2、精准可变预干燥技术，特殊设计的带有光学掩膜固化装置的预干燥固化器，可以发出可变光场，可变光场形成的图文照射到磁化滚筒上的承印物上，承印物上的油墨或清漆完成预干燥；
3、双光彩光变图文拼接技术，设计两种合适的磁场发生装置，完成固定式和可变式的双光彩光变图文的全向拼接；
4、固定图文可以是，环状，矩形，斜线；可变图文可以是数字、冠字号码、条形码、二维码等其他任意图文。
5、预干燥固化装置发出的可变光场是高动态刷新的，可变光场的刷新速率可与磁化滚筒速度匹配，照射到承印物上的图文可与承印物同步运动，以增加固化时间；
6、光学掩膜固化装置，光源可以使用LED光源和激光光源。
