Output transparent geometry is pale compared to preview

Hi all,

I’m having this issue where the preview for my transparent geometry is pale upon exporting to pdf.
Seen in this image, which is a screengrab from the Print Setup window, this is what I expect my pdf to look like,

However, upon exporting to pdf, this is my output

I’m not sure why the red is so pale. I’ve looked everywhere in the document properties and there is nothing that can boost the saturation of my output, or something that can fix this. Both the Rhino viewport and the Print Setup window were displaying the first image.

For context, I generated the geometry using Grasshopper. When I got the issue, I replicated the grasshopper output by changing the display mode to “Ghosted”, and still got the pale geometry, which makes me believe this is not a Grasshopper problem, but rather a Rhino problem.

Is there a way I can fix the pdf output from being so pale? Or is this a bug? Any help would be greatly appreciated!

Hi -
Trying that here with similar geometry and the Ghosted display mode gives me this PDF output:

Please upload your 3dm file and the result of the Rhino SystemInfo command.

Hi Wim!

Thanks for the reply. Attached is the .3dm file with the base for the geometry, and the .gh file with the geometry. I prefer to have the grasshopper output displayed when exporting to pdf. But if I must bake it and set it to Ghosted, then I’ll take it instead.

Here is the SystemInfo output:

Hi -

Those files were not attached.
Apart from that, the system looks fine. I don’t have the Enscape plug-in installed but that probably doesn’t get in the way here.

Sorry Wim! I could’ve sworn I have them attached.
