The print version won’t have them due to printing restrictions. Due you think they would benefit from being slightly subdued or are they doomed altogether? I personally think they make the text pop!
The other option was to have a version without the vignettes anyway for easier printing.
I think that they need at the very least to be subdued a lot, but I personally would prefer that they were gone completely. I think the text pops more without it, by letting it breathe a little with the added white space. If you could have provide two versions, that would be great!
