The conversion method between the PCO and SCO decides how data is converted in order to align the color response of the SCO to the PCO. The conversion method is the type of curves or DeviceLinks that ColorFlow generates in order to align the SCO color output to that of the PCO. You can select a different conversion method than the default recommendation, and later adjust the generated curves or DeviceLinks in order to fine-tune the conversion.The conversion curves and DeviceLinks that ColorFlow generates are available in your Prinergy Process Templates in the Prinergy workflow.

Note: Depending on the DeviceLink options you choose, the gamut of the SCO is either mapped or clipped. All colors from the PCO can only be reproduced on the SCO when the SCO's gamut entirely encompasses the PCO's gamut. You can generate an SCO verification report to see how well the SCO gamut covers the PCO gamut.

  1. Click the Color Setups tab, and then click the desired color setup from the list to show it in the viewer window.
  2. In the color setup viewer, click the Conversion icon between the PCO and an SCO.
  3. In the Output Version box, enter a name if you don't want to use the default version name.

  5. For a discontinuous flexographic SCO:
    • The color in the highlight region of the PCO is typically lighter, unless the PCO is also discontinuous. If the color in the highlight region of the PCO is darker and you want to improve color match across the entire tonal region, select the Allow Mindot Tint Out Increase check box.

  6. To use a DeviceLink profile, do the following:

    • If your ColorFlow edition is not licensed to generate DeviceLinks, from the DeviceLink Method list, select Imported and then click Import to import a DeviceLink profile.
    • To generate a DeviceLink profile, from the DeviceLink Method list, select the desired method. For more details, see Generating a DeviceLink profile.
    • You cannot generate a conversion DeviceLink for a discontinuous flexographic SCO. 

    • If the PCO is discontinuous, you can generate either a conversion calibration curve or a discontinuous SCO conversion DeviceLink, but you cannot generate both.
  7. Click OK.

NoteIf the SCO device condition has extended process inks, they are calibrated to match the Spot Color Tone Value (SCTV) response of same-named inks present in the PCO. For extended process inks not present in the PCO, linear SCTV calibration is performed.

PCO 与 SCO 之间的转换方法决定了用于使 SCO 颜色响应与 PCO 匹配的数据转换方式。转换方法就是 ColorFlow 为使 SCO 颜色输出与 PCO 颜色输出保持一致而生成的曲线或 DeviceLink 的类型。您可以选择不同于默认建议方法的转换方法,并在稍后调整生成的曲线或 DeviceLink 以便微调转换。由 ColorFlow 生成的转换曲线和 DeviceLink 在印能捷工作流程的印能捷处理模板中提供。

注意:根据选择的 DeviceLink ICC 选项,SCO 的色域将被映射或压缩。SCO 的色域完全包含 PCO 的色域,则 PCO 中的所有颜色均只能在 SCO 上重现。您可以生成 SCO 验证报告以了解 SCO 色域涵盖 PCO 色域的程度。

  1. 单击颜色选项卡,然后在列表中单击所需的颜色设置以便在查看器窗口中显示它。
  2. 颜色设置查看器中,单击 PCO 和 SCO 之间的转换图标
  3. 输出版本框中,如果您不想使用默认版本名称,请输入一个名称。

  5. 对于非连续柔性版 SCO:
    • PCO 白场区内的颜色通常更淡,除非 PCO 也为非连续。如果 PCO 白场区内的颜色更暗并且您希望提高整个色调范围内的颜色匹配,请选中允许增大 Mindot 色调输出复选框。

  6. 要使用 DeviceLink 配置文件,请执行以下操作:

    • 如果您的 ColorFlow 版本未获得生成 DeviceLink 的许可,请从 DeviceLink 方法列表中选择已导入,然后单击导入以导入 DeviceLink 配置文件。
    • 要生成 DeviceLink 配置文件,请从 DeviceLink 方法列表中选择所需的方法。有关更多详细信息,请参见Generating a DeviceLink profile
    • 您不能为非连续柔性版 PCO 生成转换 DeviceLink。 

    • 如果 PCO 为非连续,您可以生成转换校准曲线或非连续 SCO 转换 DeviceLink,但不能同时生成两者。
  7. 单击确定
