"Color marks assignment" subtab

Depending on the upstream prepress system, it may be feasible for print jobs containing spot colors to map the color marks defined in the prepress system to HEIDELBERG Dipco color marks in order to assign spot colors to the ink control strip and the print units.

"Method" list box

You can choose between the following options:

​•​Spot colors allowed only as of X,Z,U,V

If multiple process colors (B, C, M, Y, X, Z, U, V, ...) are imported, the first four colors are taken as standard process colors and all other colors are taken as spot colors.

​•​Color Code Assignment in PPF Order

With this option enabled, all colors present in the PPF files are treated as spot colors, and the color order is taken from the PPF information.

​•​Allow spot colors for BCMY

When importing PPF jobs with 4 colors that are not defined as process colors in Prinect Production, these are assigned to the Prinect process colors B, C, M, Y. The color order is defined in the "Color Order" list box.

No difference is made between process colors and spot colors and lower case for marks assignment. If this option is enabled, the color order is assigned to the color order CMYKXZUVS1.... regardless of the order in the PPF file. assigned.

"Color Order" list box:

The prepress system in question controls the order of process colors in the PPF files. You can choose the order you want, depending on the color order provided by the prepress system:

​•​BCMY

The order of process colors is defined as B, C, M,Y and processed in this way in Prinect Production, i.e. the black separation comes first, followed by the other colors.

​•​CMYB

The order of process colors is defined as C, M, Y, B and processed in this way in Prinect Production, i.e. the black separation comes last, preceded by the other colors.

Some prepress systems use the color order "BCMY" instead of "CMYB" for packaging printing. Usually, these colors are not recognized as process colors and therefore treated as spot colors. You can enable this option if you are operating such a prepress system (e. g. ESKO ArtPro+^TM). The colors B, C, M, Y will then be recognized as process colors and error messages due to the incorrect color order are prevented during PPF import.

New jobs are created with the "Allow Spot Colors on BCMY" setting.

​•​Case 1: Prinect Inpress Control controls the measurement processes using "Black" (color code "B"). A color must therefore always be assigned to the color code "B".

​•​Case 2: A 4-color color control strip (defined in the prepress system) can now be used instead of a 6-color color control strip.

​•​Case 3: In ArtPro+^TM, only spot colors are defined for flexo printing and there is also the "Yellow" spot color that is not to be used as process color Y but as a spot color. For example, the following colors are to be used as spot colors:

​•​PLM 1234,

​•​Yellow,

​•​PLM 5678,

​•​PLM 9876.

Then select the "Color code assignment" option in the "Method" list box. "BMCY" is selected as the color order.

"Print order" list box:

Here, you select the print order in the PPF jobs to be submitted to Press Center. The following options are available:

​•​Take print order from PPF

The print order is taken from the PPF information and submitted to Press Center without changes.

​•​Take print order from marks colors (BCMYXZ..)

When you select this option and "Allow spot colors for BCMY" is selected, the color code is assigned first and then the print order on the press is defined based on this assignment.

Example: A sheet is made up of process colors cyan, magenta, yellow and spot color PANTONE 2727 C. If "Allow spot colors for BCMY" is selected, PANTONE 2727 C is now assigned to the color code of a process color. In "Color Order" you can define the color code to which spot color PANTONE 2727 C will be assigned. In this example, the color order "BCMY" was specified. This means that the spot color PANTONE 2727 C is assigned to color code B.
