Ink Review: Tenebris Purpuratum by Franklin-Christoph

Next up in our Franklin-Christoph series is a dusty purple ink. For a brand overview of all of the inks that will be reviewed in this series, follow this link. 

Franklin Christoph Tenebris Purpuratum is a deep dusty purple that borders on aubergine. While it is dark enough for the office, I think that it is better suited to journalling and letter writing outside of work hours.

Ink Properties

Shading: There is some shading in medium and broad nibs but it isn't why you would choose the ink.
Bleed Through: Both Rhodia and Field Notes fare well but Copy Paper suffers from bleeding in all nib sizes.
Show Through: The back side of Copy paper is unusable, Rhodia and Field Notes are ready to go.
Saturation: Average saturation.
Sheen: None.
Water Resistance: This ink has no water resistance on Rhodia and is a muddy mess on Copy paper.
Drying Time: The dry times for this ink are fairly average, 20-25 seconds on Rhodia and faster on more absorbent papers.
Flow: This ink flows well with average lubrication. 
Cleaning: Easy to clean.

Conclusions

This is a really nice purple. Diamine Damson is the closest comparison ink I have on hand and the Franklin-Christoph offering is the hands down winner on colour comparison between those two. It writes nicely, has a little shading in wider nibs and doesn't feather. Bleed through is an issue on Copy paper so I'll have to confine its use to paper worth writing on. This one is a keeper.
