Print preview plate by plate, computed from the print data

Where to find itView › Overprint Preview (⌥⇧⌘Y)

The print preview calculates plates from the same print data used for PDF output. CMYK images keep their channel values, while RGB images pass through their embedded profile. For a magazine cover, check whether a black headline overprints and a spot colour appears on the right plate. Separation preview shows individual plates, and overprint preview shows their combined appearance with opacity. Chrome and Safari can display the preview in Display P3 on suitable screens. The view itself changes no output settings.

How to do it

1. Open «View › Overprint Preview».
2. Choose a plate under «View» › «Separations preview».
3. Compare spot colour and black with the combined print.

Tips

• Use ⌥⇧⌘Y to toggle overprint preview.
