具体实施方式
本发明实施例提供了一种宽色域打印流程及方法，能够打印更宽色域的颜色，提高目标图像的颜色效果和视觉质量。
为了使本领域技术人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行更为详细地描述，显然，如下所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域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，都属于本发明保护的范围。
本发明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。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，包含了一系列步骤或单元的过程、方法、系统、产品或设备，不必限于清楚地列出的哪些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
如图1所示，Lab色域是理论上人眼可以看见的所有颜色的色域，它是一种与设备无关，既不依赖光线、也不依赖颜料的基于人眼生理特征的颜色系统，也正因为此，Lab色域的颜色并不能完全被显示器或颜料所呈现。
在图1当中，虚线框所示的是RGB色域，RGB色域是工业设计中运用最广的一种颜色标准，其通过对红(Red)、绿(Green)、蓝(Blue)三个颜色通道的变化以及它们相互之间的叠加来得到各式各样的颜色的，RGB即代表光的三原色(红、绿、蓝)；粗线框所示的是CMYK色域，CMYK色域是工业生产中 常规的印刷颜色标准。在工业生产中，一件产品上的图像需要先经过在计算机的设计，然后才能生产印刷。
但是由于颜料是吸收光线，不是光线叠加，因此实际上颜料打印出来的图像的色域是要小于电子计算机通过显示器反馈的图像的色域，印刷颜色标准的CMYK色域其实是工业设计颜色标准RGB色域的子集，其范围小于RGB色域。这种通过常规印刷手段打印的图像不但与计算机中设计的图像有色域差别，更与人眼肉眼所看得见的图像存在很明显的色域空白，可以参见图1所示的CMYK色域与Lab色域之间的空白区域。
为提高现有技术中常规印刷手段CMYK方式打印形成的图像的颜色效果和视觉质量，即为了提高打印目标图像的颜色的色域。以喷墨打印为例进行说明，如图2所示，本发明实施例中一种宽色域打印流程的一个实施例包括：
S101、打印预涂层；
喷墨打印是将彩色液体油墨经喷嘴变成细小微粒喷涂到记录介质上(比如纸张)，所打印的图像质量的通常取决于此次喷墨打印的打印分辨率，也就是DPI值。DPI(Dots Per Inch，每英寸点数)是一个重要的量度单位，它指的是每英寸的范围内喷墨打印机可打印的墨点数，一般来说，DPI值越高，表明喷墨打印的打印精度越高、打印分辨率也越高。
影响图像质量的另外一个重要因素是记录介质的吸收问题，当油墨被喷射到纸张上的时候，它应当紧奏对称。如果油墨被纸张吸收，并且扩教，那么墨点的面积就会比预计的要大，结果就使得目标图像看起来更模糊。
本实施例为了克服这一点，让后续油墨更好地喷涂于记录介质上，不会出现油墨不稳定地随机散开现象，在该记录介质的表面上打印一层预涂层，以提高喷涂效果。
与传统的方式不同，传统的预涂层是通过滚筒将预涂层涂覆于记录介质上的，不但操作繁琐且厚度不好把握，而且只能在记录介质上满版涂布，浪费极大，并且对介质印刷面的平整度要求较高，还存在滚筒滚动时与记录介质粘附在一起的现象，严重影响了后续油墨的打印。
对此，本实施例采用喷涂方式在记录介质的表面打印预涂层，不存在与记录介质接触的问题，因此对记录介质的印刷面的平整度没有要求。而通过控制喷嘴的喷墨量，还可以精准的控制预涂层的打印厚度，避免浪费。
在一个优选的实施例中，该预涂层可以被精准的控制在所要打印的目标图像区域范围内，即对应所要打印的目标图像的大小和位置精准地喷涂在记录介质的表面上，以此减少不必要的浪费。
应理解的是，上述记录介质可以包括但不限于纸张、皮革、金属、玻璃、陶瓷、塑料、木质以及其他材料。还可以理解的是，该预涂层的成分可以针对不同的记录介质，一种材料的记录介质对应一种成分的预涂层，具体此处不做限定。
S102、打印基础图像；
本实施例中，可以在预涂层之上打印一层基础图像，该基础图像即由常规印刷手段CMYK方式打印，具体可以是通过三个或四个喷头分别喷涂青色、品红色、黄色和黑色。当然，也可以采用共用一个喷头的方案，在一个喷头中设置多组喷嘴分别对应青色C、品红色M、黄色Y以及黑色K，如图3所示，在CMYK的每组中可以包含有16个喷嘴，也就是在一个喷头中设有4组16个喷嘴，即64喷嘴的喷头。
采用多喷嘴的方式是因为：常规的设计是只有在打印需要时才喷射油墨，即随机式喷墨，它与连续式喷墨相比，结构简单，成本更低，可靠性也更高，因此广为采用；但是，受射流惯性的影响，导致墨滴喷射速度降低，为了弥补这一缺点，因此采用多喷嘴组合的方法来提高打印速度。
可以理解的是，该集成在一个喷头中的每组喷嘴可以不限于16个，此处以16个为例示意说明。
并且，每个喷嘴采用的喷墨方式可以是微压电式，通过控制压电元件收缩推出墨滴；也可以是热气泡式，通过将油墨在短时间内的加热、膨胀、压缩喷射出墨滴，具体此处不做限定。
S103、打印补偿图像；
上述基础打印步骤中所打印的基础图像即由CMYK油墨打印的青色、品红色、黄色、黑色或其组合颜色的图像。由于CMYK色域不但小于显示器的RGB色域，还要远小于人眼可见的Lab色域，该由CMYK油墨打印的图像实际上与人眼所见的期望颜色存在很大差别。
对此，本实施例中，在该CMYK油墨打印的基础图像之上补充增加了补偿打印步骤，即在基础图像之上打印补偿图像。
可以理解的是，所打印补偿图像的补偿颜色可以是除CMYK颜色(青色、品红色、黄色、黑色)以外的其他色域的颜色，例如可以是紫色、橙色、绿色、宝蓝色、大红色中的一种或多种颜色，具体可以根据实际打印的目标图像的需求进行选择。
本实施例中，该补偿颜色可以对应每一颜色设置一个喷头，或者可以将该补偿颜色采用与CMYK颜色所不同的喷头(即至少两个喷头)，又或者也可以采用集成为一个喷头的方案，如图4所示，在一个喷头中集成多组喷嘴，其中P1、P2、P3等即分别对应不同的补偿颜色。当然在该集成多组喷嘴的一个喷头中，其排布组合方式并不限于图4所示，该水平排布的喷嘴也可以是垂直排布，或以矩阵形式排布，具体此处不做限定。
需要说明的是，本实施例中，所打印的补偿图像可以覆盖打印在基础图像上方，也可以打印在基础图像的空白区域中。即可以将该与CMYK色域不同的补偿颜色单独打印呈现在记录介质上，或者可以将该补偿颜色打印在CMYK颜色之上，与该CMYK颜色混合调配出其他色域的颜色，以实现更宽的色域打印。
S104、打印光油层。
本实施例中，前述步骤打印的基础图像和补偿图像形成最终的目标图像，而在该目标图像之上可以打印一层光油层，该光油层可以对目标图像起到防水防潮的作用、也可以隔绝空气，避免油墨氧化变质等，而且还可以保证目标图像的光泽度，使得其视觉质量更舒适。
另外，本实施例中某些局部光油能起到突出局部的特殊效果。
本发明实施例通过在CMYK打印的基础图像之上补偿打印其他色域颜色的补偿图像，能够实现多种色域颜色的组合、叠加和混合，实现宽色域的打印，提高目标图像打印的颜色效果和视觉质量。
在本发明的一些实施例中，在步骤S101和步骤S102之间可以设有步骤S105，如图5所示，本发明实施例中一种宽色域打印流程的另一实施例包括：
S105、打印白色底层。
在打印CMYK颜色的基础图像之前，可以在该预涂层的表面通过白色底墨再打印一层白色底层。打印白色底层可以提高后续油墨打印的基础图像和补偿图像的对比度，使其色彩对比分明，以及个别特殊产品需求白底时打印白色底层。
可以理解的是，该白色底墨可以单独采用一个喷头，或者也可以与基础打印和补偿打印的喷头集成为一体，在一个喷头中集成该白色底墨的打印喷嘴，具体此处不做限定。
该白色底层也可以对应所要打印的目标图像的大小和位置精准地喷涂在记录介质的表面上。
在本发明的一些实施例中，在步骤S103和步骤S104之间还可以根据需要设置步骤S106，如图6所示，本发明实施例中一种宽色域打印流程的另一实施例包括：
S106、打印金属色图像。
在打印覆盖光油层之前，在该最终打印的目标图像之上还可以进行金属色表面处理，通过金属色油墨在该目标图像上喷涂上金属色图像(也可以称为金属色油墨层)。
该金属色油墨可以根据实际需求选取金色、银色、太空灰色、铝合金色等，在该目标图像上的特定位置或整个覆盖打印，使得所打印的目标图像更加具有特点，增强科技感。
需要说明的是，该金属色油墨也可以单独采用一个喷头，或者进一步的可以与白底打印、基础打印、补偿打印的喷头集成为一体，具体此处不做限定。
需要说明的是，打印流程还包括烘干步骤，分别对应预涂打印步骤、白底打印步骤、基础打印步骤、补偿打印步骤、金属色打印步骤以及光油打印步骤，用以分别固化预涂层和光油层，以及至少部分固化白色底层、基础图像、补偿图像和金属色图像。本发明实施例中，在步骤S101形成预涂层之后可以进行烘干加工，使预涂层稳定敷在记录介质上。并且，在步骤S102、步骤S103、步骤S105和步骤S106中每喷完一种颜色油墨之后或连续喷几种颜色油墨后可以一起进行初步烘干，使得所打印的油墨层(图像)至少部分固化，之后在步骤S104涂覆光油层之前进行完全烘干，使油墨层(图像)完全固化。然后才在步骤S104涂覆上光油层之后进行最终烘干，得到最终产品。通过将油墨层(图像)最终烘干/固化后再涂覆光油层，避免一起烘干时由于光油层的隔档导致油墨层(图像)的烘干不彻底，可以保证最终的光油层的防水防潮、隔绝的保护效果。
其具体的烘干方式可以取决于油墨的性质，如果是UV油墨则采用紫外线灯光照射的方式固化，如果是水性油墨则采用红外光、热风、过热蒸汽等方式 烘干，此处不对油墨的性质做限定。
对应的本发明实施例中，基于图2至图6所示实施例，有关于目标图像的打印可以参阅图7所示，本发明实施例的一种宽色域打印方法的一个实施例包括：
S210、获取目标图像；
本实施例中，图像可以由打印设备控制喷头(喷嘴)喷射出墨滴进行打印，在打印之前，该打印设备可以获取到所要打印的目标图像，例如通过数据接收的方式获取该目标图像。
S220、确定目标图像的补偿图像；
在该打印设备获取到目标图像之后，可以对目标图像进行分析，分析该目标图像中颜色所属的色域，以确定该目标图像中属于CMYK色域的区域以及属于该CMYK色域以外的区域。
可以理解的是，在该目标图像中，该属于CMYK色域的区域即基础图像，该属于CMYK色域以外的区域即补偿图像。
并在确定了补偿图像之后，该打印设备还可以对应确定打印该补偿图像所需的每种补偿颜色。
S230、根据补偿图像确定补偿路径；
应理解的是，从该目标图像中分析得到的补偿图像的数量通常为多个，且不均匀地分布在目标图像上。
因此，本实施例中，为了减少打印该补偿图像所花费时间，可以规划一条补偿路径用以打印该目标图像上不均匀分布的补偿图像。
可以理解的是，依据补偿图像在目标图像上的分布位置不同，可以不同于现有技术中横向或纵向的逐层打印方式规划一条连接所有补偿图像的补偿路径，因而不需要经过全部的目标图像，以减少喷头(喷嘴)在移动中花费的时间，提高打印效率。
S240、通过补偿路径打印补偿图像。
本实施例中，打印设备可以控制喷头(喷嘴)按照所确定的补偿路径移动，打印该补偿图像。
需要说明的是，打印设备在打印该补偿图像之前可以预先打印该CMYK色域的基础图像，然后在该基础图像之上使用补偿颜色打印补偿图像。
可以理解的是，打印设备打印该基础图像的方式可以是现有的横向或纵向逐层打印方式。当然，如若该打印设备在分析要打印的目标图像时，得到该基础图像的区域占比小于预设值，则可以按照步骤S230所述的方法，确定打印该基础图像的基础路径，并按照该基础路径进行打印以提高打印效率。
该打印设备中预设的区域占比的预设值具体可以由用户根据实际生产需求调整设置，例如设置为30％。当检测分析到小于30％时，也就意味着补偿图像的占比超过了70％，此时打印设备可以自行将打印补偿图像的补偿路径设置为常规的打印方式，即以横向或纵向的逐层打印方式打印该补偿图像，避免打印设备执行过多不必要的计算过程，强化生产效率。
本发明实施例中，通过分析目标图像中包含的基础图像以及对应该基础图像所要补偿的补偿图像，依据该补偿图像在目标图像上的分布位置，规划连接所有补偿图像的补偿路径，以达到减少喷头(喷嘴)移动的时间，减少喷涂补偿图像所需时间，提高打印效率的目的。
下面对本发明实施例中的步骤S230进行举例说明。请参阅图8所示，基于图7所示实施例，本发明实施例的一种宽色域打印方法的一个实施例中步骤S230包括：
S231、确定起始位置；
本实施例中，打印设备可以以目标图像左上角、右上角、左下角或右下角为初始打印的起始位置。
在一些实施例中，该起始位置也可以在目标图像的中间位置，具体此处不做限定。
S232、获取补偿图像上的补偿位置集合；
本实施例中，打印设备可以相对于该起始位置，以该起始位置为原点坐标确定每一个补偿图像的坐标得到一个坐标集合，即补偿位置集合。
S233、根据起始位置和补偿位置集合确定补偿路径。
本实施例中，以该起始位置为补偿路径的开始端，打印设备可以通过寻找在补偿位置集合中与起始位置距离最短的补偿位置，并以该补偿位置为新的起始位置寻找与它距离最短的下一补偿位置，直至寻找到该补偿位置集合中最后的一个补偿位置的方式，将该寻找路径确定为补偿路径。
具体的，该补偿路径的路径方向至少包括第一方向和第二方向，以左上角 为起始位置为例，该第一方向即从该起始位置向右的方向，该第二方向即从该起始位置向下的方向；而以右下角为起始位置为例，该第一方向即向上的方向，该第二方向即向左的方向。具体对应不同的起始位置，该第一方向和第二方向亦不同，并且在起始位置设置在目标图像的中间位置时，其关联的补偿路径还可以包括第三方向和第四方向，在此不对其做限定。
而在补偿路径的第一方向和第二方向的基础之上，可以根据第一方向和第二方向将补偿位置集合划分为第一补偿位置集合和第二补偿位置集合，该第一补偿位置集合即位于起始位置的第一方向一侧的补偿位置集合，该第二补偿位置集合即位于起始位置在第二方向一侧的补偿位置集合。
需要说明的是，本实施例中可以依据该第一补偿位置集合和第二补偿位置集合的权重来确定补偿路径向第一方向移动或向第二方向移动。该第一补偿位置集合的权重与第一补偿位置集合中每一补偿位置与起始位置在第一方向上的距离相关联，该第二补偿位置集合的权重与第二补偿位置集合中每一补偿位置与起始位置在第二方向上的距离相关联。
以图9所示为例，将目标图像量化为平面的坐标，设置该起始位置的坐标为(0，0)，则该第一(第二)补偿位置集合的权重与每一补偿位置与起始位置在第一(第二)方向上的距离关联关系可以是指每一补偿位置的坐标(X，Y)在X轴或Y轴上的值的大小，即该X轴可以对应第一方向，该第二方向可以对应Y轴。
在图9中，假设补偿位置分别为1、2、3、4、5、6、7、8、9、10、11、12，相应的坐标分别为(2，2)、(3，2)、(3，3)、(2，3)、(7，3)、(8，3)、(1，6)、(1，7)、(5，7)、(6，7)、(5，8)、(6，10)，从中可以计算得到第一方向的权重为49，第二方向的权重为61。
本实施例中，为减少移动距离，向距离最近的补偿位置移动，因此可以默认设置向权重小的一方移动，如比较于权重61的第二方向，以权重小的为49的第一方向确定为移动的补偿路径。
当然，假设补偿位置为n个，则可以通过以下求和计算式计算得到第一方向的权重或第二方向的权重，该计算式可以为：
Figure PCTCN2020089037-appb-000001
其中a可以指代X轴或Y轴，即a1可以为X1，或者Y1。
应理解的是，本实施例中以求和计算为例进行举例说明打印设备如何规划补偿路径，但不应构成对本发明的限定，在本发明的其他实施例中也可以采用除求和计算以外的方式计算得到第一方向和第二方向的权重，具体此处不做限定。
如图9所示，当打印设备确定第一方向权重小于第二方向，即在补偿路径中由起始位置0开始向第一方向移动(X轴方向)，之后向第二方向移动(Y轴方向)，将补偿路径规划至补偿位置1处。
在此之后，打印设备可以以该补偿位置1为起始位置再次寻找距离最近的下一补偿位置。而由于补偿位置1、2、3、4相互接近，因此在相互接近的补偿位置中所规划的补偿路径可以是传统的打印方式横向逐层(1234)或纵向逐层(1432)，同理该方式也可适用于图9所示的相互接近的补偿位置(5、6)、(7、8)和(9、10、11)中。
假设上述补偿路径截止至补偿位置4处，以该补偿位置4为新的起始位置寻找下一距离最短的补偿位置，具体方式可以同上述起始位置0至补偿位置1的计算方式。当然，此时的补偿路径在补偿位置4处还存在第三方向，即-X轴方向的第三补偿位置集合7和8。但其并不影响计算此时第一方向、第二方向以及第三方向的新的权重，继续以图9为例，此时补偿位置5、6、7、8、9、10、11、12的坐标分别为(7-2，3-3)、(8-2，3-3)、(1-2，6-3)、(1-2，7-3)、(5-2，7-3)、(6-2，7-3)、(5-2，8-3)、(6-2，10-3)，即新的坐标(5，0)、(6，0)、(-1，3)、(-1，4)、(3，4)、(4，4)、(3，5)、(4，7)。
以上，从中计算-X轴的第三方向的权重为|-2|，并计算得到第一方向的权重为25，第二方向的权重为27。取他们的绝对值，可知第三方向的权重最小为2。因此，在所规划的补偿路径中可以先向-X轴方向移动(第三方向)，然后向Y轴方向移动(第二方向)，规划补偿路径之补偿位置7处。在此之后以补偿位置7为新的起始位置继续寻找距离最短的下一补偿位置直至所述补偿路径衔接所有的补偿位置。当然其中可能出现的第四方向的权重可以参照第三方向计算得出，具体此处不再穷举。
在一个优选的实施例中，以图10所示为例，在该打印设备处理分析目标图像的时候，可以将一定范围内的补偿位置一并纳入为一个补偿位置单元，例如 图10中虚线所示，在确定补偿位置1为最接近的位置时，可以采用横向逐层(123456)或纵向逐层(561423或234165)的方式规划打印该补偿位置1所在的补偿位置单元，相应的可以减少打印设备在规划补偿路径时的计算工作量。
可以理解的是，该补偿位置单元的范围具体可以由用户根据实际打印需求设置，例如可以如图10所示的将与该相互接近的补偿位置(1234)距离间隔小于2的补偿位置(56)合并为一个补偿位置单元。应理解，在该目标图像中，补偿位置单元可以包括多个，即补偿位置集合中可以包括多个补偿位置单元。
本发明实施例中，设置起始位置点，计算以该起始位置为开始点的补偿路径，通过判断在当前起始位置的第一方向和第二方向的权重，确定由该起始位置向距离最短的补偿位置移动的方向，规划出一条相对现有技术中横向或纵向逐层打印方式路程较少的补偿路径，并以此补偿路径控制喷头(喷嘴)的移动，从而达到减少喷涂补偿图像所需时间，提高打印效率的目的。
