You should avoid mixing RGB colors with CMYK or spot colors, as good practice.
Spot colors
| Tip |
|---|
Allowed and/or strongly encouraged practice |
It is perfectly OK to use spot colors (or Pantone) in files prepared for Wedia. If you use spot colors, don’t forget to configure the knock-out / overprint parameters, to ensure your PDF created from the platform will be displayed correctly when it will be given to the printer (read next paragraph).

This parameter is essential to create self-sufficient documents when you are using spot colors. You have to choose the best solution to use; we recommend to contact your printer to define the right parameters to apply, depending on the ink and the paper you will use.

TipAdobe InDesign is configured by default in knock-out. |
Handle the knock-out
for the texts: in your paragraph style, in the section Character Color, you will find two check-boxes to check to command the fill and stroke overprint.
for vectorial frames: the knock-out is handled in the object style, in the sections Fill and Stroke.
Convention in naming colors or gradients
When you create a new swatch of color or of gradient, you must name it respecting the following instructions:
never use accented characters
never use special characters
never use the symbols "<" or ">"
never insert spaces (" "); replace them with underscores ("_")
never start a name with a number
make a preference for lowercase
Tint areas

Allowed and/or strongly encouraged practice |
In tint areas frames, you can use tints below 100%. But for texts paragraph and tables, you must create a specific style and proceed to validation tests before.

...
You can use them on tint area frames. But they are not supported on text frames; for the cells fill in a table: the opacity effects must be configured in the cell styles (InDesign only).

Rich Black

You will then have a swatch with a powerful ink covering. Such rich black must be reserved for tint areas only. It musn’t be applied on texts, as it could cause registration issues for the printer.
Clear unused swatches
Once you have finished your layout, we recommend you to delete all unused swatches. This cleaning comes in line with the fact you are preparing your file meticulously for the platform.
