White ink and Certified Process for Color Confirmation - User Guide

You can use the Certified Process for Color Confirmation for proofs printed with white flood by the Epson Stylus Pro WT7900 printer and in white ink.
Note: This topic provides a high-level overview of tasks. For details, see the applicable user guide topics.

Additional processing requirement

For proofs with white flood (that is, white ink printed under colors) to pass the Certified Process for Color Confirmation, the same recipe for white flood must be printed under the color bar and under the proof.

This requirement is in addition to the other requirements for Certified Process for Color Confirmation.

Connectivity requirement

Only Kodak Proofing Software with the Open Connectivity Kit can be used to process input files with white content for the Certified Process for Color Confirmation and to print white content with white ink and the Epson Stylus Pro WT7900 printer.

Direct connectivity cannot currently process input files with white content and print the content with white ink and the Epson Stylus Pro WT7900 printer.

Color bar artwork setup

You can add white flood to both user-defined and default color bars.

For user-defined color bars, you use Adobe Illustrator or other software to create the artwork and add or exclude a patch for white flood.
When the artwork excludes white flood, you configure an Open Connectivity Kit hot folder to add white flood to the color bar when you set up the color bar for the Certified Process for Color Confirmation.
For default color bars, you can export only a CMYK PDF file of the artwork.
Because the artwork lacks white flood, you configure an Open Connectivity Kit hot folder to add white flood to the color bar when you set up the color bar for the Certified Process for Color Confirmation.

Color bar processing setup

How you set up the color bar for the Certified Process for Color Confirmation depends on whether the artwork includes or lacks white flood.

When the artwork includes white flood, configure an Open Connectivity Kit hot folder to specify which recipe from a color library to use for white flood.
When the artwork lacks white flood, configure an Open Connectivity Kit hot folder to add white flood.

White recipe setup for color bars and proofs

The following table outlines how to use the Open Connectivity Kit to add proofer or press white flood to color bars.
Note: Regardless of how you add white flood to a color bar, you must note the recipe that you used for white flood because you need to use the same recipe for the white flood in input files.

Add white flood to color bar artwork

Note the recipe for white flood

Use the same white flood recipe for proofs

Perform one of the following actions:

On the hot folder White Settings tab, select Use proofer white flood, and specify a white level.
On the White Settings tab, select Use press white flood, and select a recipe for white flood.

The software adds white flood to the artwork when you color manage the color bar for the first time.

For proofer white flood, the selected white level produces the following recipe:

Cyan 0, Magenta 0, Yellow 0, Black 0, White <value from the > White Level (%) <box>

For press white flood, the selected recipe appears on the White Settings tab.

For input files that lack content for white flood, click the White Settings tab to add proofer white flood or press white flood.

For input files that include content for white flood, click the Spot Colors tab to select a library that includes a recipe for the object in the input file that defines white flood.

In both cases, ensure that the recipe for white flood is the same recipe that was used to color manage the color bar with white flood.

Color-management setup for color bars

When artwork for a color bar includes a patch for white flood, you use a different process to identify the white flood recipe when you set up the color bar for the Certified Process for Color Confirmation.

First, in Proofer Administrator, identify which recipe you want to use for the artwork patch that defines white flood for the color bar.
Next, when you set up the hot folder to color manage the color bar for the first time, select the color library that contains the recipe you want to use, and turn off white flood.

The following table outlines how to set up color bar artwork that includes white flood.

Resulting recipe for white flood

Use the same white flood recipe for proofs

In Proofer Administrator, edit the color bar and select the recipe that you want to use for white flood. The name of the recipe must exactly match the name of the artwork patch that defines white flood.

On the hot folder Spot Colors tab, select the library that contains the recipe for white flood in the artwork.

On the White Settings tab, select Do not use white flood.

The software uses the recipe to print white flood for the color bar artwork when you color manage the color bar for the first time.

After you color manage the color bar the first time, the recipe appears in Proofer Administrator for the color bar.
