Spot swatch color is not saved correctly when changing the color of an existing swatch
Details of your operating system: Microsoft Windows 10 Pro (10.0.19045 Build 19045)
The version of Adobe Illustrator (desktop): 30.0
The steps you were taking when you experienced the issues:
Create a new document, add a spot swatch and set the color to 100% cyan (or any color). Apply this spot swatch to an object, like a rectangle for example. Save the document as an .ai file. Then, change the color of the spot swatch to a different color (for example 100% yellow, or any color). Save the document again as an .ai file. Open the document in Acrobat.Your expected result and the actual result:
Expected result is that the rectangle in the file when opened in Acrobat should be 100% yellow, following the example above, or whatever the spot swatch color was changed to. Actual result is that the rectangle remains the original color when the document was first saved. If the spot swatch is changed, then copied into a new document then it displays correctly when saved.Upload your Illustrator file or a video (screen recording or gif, this helps us most to reproduce the issue and resolve it)
Open the file in Illustrator and the rectangle is yellow. Open the file in Acrobat and the rectangle is cyan.
Why does this matter? Many production printing RIPs use the embedded PDF data in the .ai file. If the spot swatch color data is not being updated correctly on a subsequent file save this causes issues in production workflows.
Reproducible at the team’s side, will be fixed
