I am uploading this review yet again to show the addition of a TWSBI Diamond 580's broad nib into the mix. It is a wet writer, and the shading with this ink is beautiful.
This review was scanned at 600dpi on an HP Deskjet F4280.
Because these scans are done with a light emitting printer, actual
colors will, more likely than not, be slightly darker than they may
appear, here. The
colors shown, here, are probably a bit more reminiscent of what the ink
would be like under a bright light or if it were held up and viewed
with a light behind it.
