To calibrate the white channel for printing on black or transparent media, you must set up layered printing at the VUTEk print station before printing the charts.

1. Right-click each RTL file and create a multi-layer job.
2. For all charts except the one with "Ink Limit and Linearization_W" in its name, do the following:
   1. For the top layer, clear White.
   2. For the bottom layer, select White Flood.

      You can improve the ink coverage, by selecting three layers on the Multilayer panel and adding a second white layer. Select White Flood for the middle and bottom layers.

3. For the white calibration chart (Ink Limit and Linearization_W), do the following:
   1. For the bottom layer, select White From Image.
   2. For the top layer, clear White.

      You can improve the ink coverage, by selecting three layers on the Multilayer panel. Then, for the middle layer, click Select Image, and browse to the RTL file that was used to create the multi-layer job. When the file has been loaded, clear all the colors for the middle layer, except White.
