Foldfactory.com offers digital white ink printing on a variety of substrates. One of the greatest benefits of using white ink is the ability to show an intense pop of white on a colored sheet. We can print white ink on its own, or as an additional spot color combined with CMYK. We can also apply the white ink as a foundation and print full color on top of it—which would give you the ability to print a brightly-colored photograph onto a black sheet of paper, for example.

To set up your file for white ink printing using Adobe InDesign, please follow these steps.

1. Create a new layer on which you will create the white ink portions of your design. Name this layer “White.” Please make sure the W is capitalized, as the software we use to print is case sensitive.
2. Once this layer is in place, create a new color swatch. Open your color palette by clicking “Window,” then “Color,” then “Swatches.” The Swatch Palette will appear.
3. Click in the upper right corner of the Swatch Palette and select “New Color Swatch.” The new color will default to black, but we recommend making it a light blue color so you can see what will be white more clearly; 20% Cyan is a good option. 
4. Click on the Color Type drop-down menu and select “Spot.” Change the Swatch Name to “White” (case sensitive). Click “OK.”
5. On the White layer and using the White spot color, create the design elements that you wish to have printed with white ink. For white ink to be printed behind a design element with CMYK four color printing, trace the desired shape.
6. When you’ve created your white ink elements, click “Window,” then “Output,” then “Attributes.” Check the box next to Overprint Fill and Overprint Stroke (if applicable).
7. When you save your file, the “White” layer should be the top layer.

Your Adobe InDesign print file including white ink printing should now be ready for submission to Foldfactory.
