Color Layer Items InDesign

Script for Adobe InDesign

Change the color or overprint of all elements on a selected layer.

  • Change fill or stroke color, or leave either unchanged
  • Set overprint on or off, or leave unchanged
  • Adapt open source to customize or create other scripts

For the Illustrator version of this script, see Color Layer Items

How to use the script

The interface is a single section with all options. The only option required is the choice of layer. All other choices are optional. Click the OK button, and all items on the selected layer are modified as directed.

Layer — the layer to color. All items on the layer, on all pages, are affected.

Fill swatch — the swatch to assign to the fill of any item that currently has a fill color. Any item that has no fill remains unchanged. If a swatch is not selected in the drop-down list, the fill of all items remains unchanged.

Fill overprint — enable and select On or Off to change the fill overprint of all items on the layer. Disable and the fill overprint of all items remains unchanged.

Stroke swatch — the swatch to assign to the stroke of any item that currently has a stroke. Any item that has no stroke remains unchanged. If a swatch is not selected in the drop-down list, the stroke of all items remains unchanged.

Stroke overprint — enable and select On or Off to change the stroke overprint of all items on the layer. Disable and the stroke overprint of all items remains unchanged.

Regarding overprint

When told to overprint fill or stroke, and the item color is zero percent CMYK, the script does not enable overprint, and when done, alerts the user “Items with no color (white) were not set to overprint.” This behavior is limited to changing overprint, meaning, when items already set to overprint are changed to no color (white), but overprint is not changed, there is no warning. In this case, InDesign disables the overprinting.
