CREO Prinergy (Harmony curves) When printing the first P2P target, using the pre-set *** NONE *** setting in both Current or Target should produce an un-calibrated plate. However on rare occasions *** NONE *** has been seen to trigger hidden calibration values which are not retained when *** NONE *** is replaced by a userconstructed curve, which then causes the G7 process to fail. Symptoms of this failure include unexpected dot values on plate and/or incorrect gray balance or NPDC curves after G7 calibration. If in doubt, print the first P2P target using your own ‘Custom Linear’ calibration curve constructed from Current and Wanted curves, as follows: Constructing a Custom Linear Current curve in Harmony • Click File – New Curve – Current … • In Current Curve Properties make sure Curve Set is ‘CMYK Curves’ • Enter the other required property values • Click File – Save Curve As … with a suitable name, e.g. ‘Custom Linear Current’ Constructing a Custom Linear Target curve in Harmony • Click File – New Curve – Target … • In Target Curve Properties make sure Curve Set is ‘CMYK Curves’ • Enter the other required property values • Click File – Save Curve As … with a suitable name, e.g. ‘Custom Linear Target’ Constructing a Custom Linear Calibration curve in Harmony • Click File – New Curve – Calibration … Exporting G7 Curves for Harmony • In Create Curves, select Single channel file set and click Export • Save the resulting folder with a suitable name, where it can be accessed from within Harmony Loading G7 Curves into Harmony • In the Harmony Target Curve window, select the Black channel • Click Edit – Import Curve Profile... and load the black curve from the Single channel file set folder • Repeat for the Cyan, Magenta and Yellow curves • Save the Harmony Target curve and proceed as normal 当打印第一个P2P目标时,Harmony curves的当前值和目标值应该为无,也就是不加载曲线出一张直线版。 |

当打印第一个P2P目标时,在当前值或目标值中都使用预先设置的*无*设置产生未校准的板。(理解为出直线版) 但在极少数的情况下,可能会看不到隐藏的校准值,当*无*被用户替换时,这些值不会在曲线上保留,从而导致G7过程失败。这种故障包括G7校准后,板材上出现意外的点值和灰平衡或NPDC曲线不正确。 如果有疑问,使用你自己的“自定义线性”校准曲线打印第一个 p2p 目标,这些曲线是由当前和想要的曲线创建的,如下所示: 在harmoy中新建自定义当前值曲线 •单击文件–新建曲线–当前值 •在当前曲线属性中,确保曲线集是“CMYK曲线” •输入其他需要的属性值 •点击文件-保存曲线…并使用适当的名称,例如“自定义当前值曲线” 在harmoy中新建自定义目标值曲线 •单击文件-新建曲线–目标值 •在目标曲线属性中,确保曲线集是“CMYK曲线” •输入其他需要的属性值 •点击文件-保存曲线…并使用适当的名称,例如“自定义目标值曲线” 在harmoy中新建自定义校准曲线 •单击文件-新建曲线–校准值 为harmoy导出G7的曲线 •在创建曲线中,选择单个通道文件集并单击导出 •使用合适的名称保存结果文件夹,以便在Harmony中访问 加载G7曲线到harmoy中 •在harmoy目标曲线窗口中,选择黑色通道 •点击编辑-导入曲线…从单通道文件集文件夹加载黑色曲线 •对青色、品红和黄色曲线重复上述操作 •保存harmoy目标曲线并正常使用 |
