Spot conversion to Process may produce slightly different colors
In Evo 9.0 we improved color accuracy when converting Lab-defined Spot colors to CMYK. This may yield slightly different CMYK builds when compared to conversions by previous Evo versions. Because of this we recommend you re-proof after upgrading to 9.0. This only affects Spot colors with a Lab Alternate Color Space and recipe, extracted from either the file or the Color Database.

Since Prinergy Evo 10.0, this feature is no longer supported due to the following reasons. We recommend that customers use the Hot Folder workflow.
As of Prinergy Evo 8.1, CEPS file formats (for example, CT/LW) are no longer supported either as input to Prinergy Evo Workflow or as output generated from Prinergy Evo Workflow.
The following ColorConvert problems have been identified:
Color matching certain files with transparent objects can result in significant changes in appearance. The problem is file specific and is dependent on the transparency blending modes applied, the object's color and the DeviceLink or ICC profile used to colorconvert the objects. The problem occurs because each graphic and image object used in the transparency group is color-converted separately. Blending of the objects in the destination color space changes the appearance.
Recommendation: Flatten the PDF files. If your PDF files contain RGB data, it is highly recommended to Color-Convert this data prior to flattening. Please refer to Partner Place Answer ID 72326 for best practices and setting up a 2-Step refine.
Note: Contone proofing cannot be used to predict this issue when colormatching is performed on final output.
ColorMatch vector overprint handling of certain files with transparency groups that also use overprint management can generate unexpected results. The new objects generated by the ColorMatcher vector overprint handling process end up ruining the appearance. Contone proofing with raster overprint handling cannot be used to predict the problem with vector overprint handling used on final output. See the Prinergy help for detailed descriptions about the processing differences between raster and vector overprint handling.
Recommendation: Flatten the PDF files. If your PDF files contain RGB data, it is highly recommended to Color-Convert this data prior to flattening. Refer to Answer ID 72326 for best practices and setting up a 2-Step refine.
RGB Transparency Blend Color Space is not supported. Blend spaces should only be defined as DeviceCMYK.
Recommendation: Change the blend space in the input file or set up a Preflight+ profile to detect and/or fix the condition.
