Ink Review: Deep Dark Purple by Cult Pens (Diamine)

An overview of the inks within this review series is available here. This ink is dark enough that it could be used in the workplace without raising too many eyebrows, especially if you were to stay to the finer end of the nib spectrum. Dry times are an issue so lefties beware.

Ink Properties

Shading: Subtle shading in broad nibs, more by accident than by design.
Bleed Through: I would consider the back side of Field Notes to be unusable. Copy paper experiences minor bleed through but is still very usable.
Show Through: Absorbent papers exhibit show through. This ink is a very dark colour so the show through may be distracting to some users.
Saturation: Highly saturated.
Sheen: None.
Water Resistance: No useful water resistance.
Drying Time: Long, 35 seconds using an EF nib on Rhodia.
Flow: Wet writer. Higher than average lubrication. 
Cleaning: Average.

The trace is lead with a band of dark violet that fades to washed out indigo where the sample was applied to the wicking media.

Conclusions

This ink is the most lubricated out of the six Cult Pens inks tested. There is something enjoyable about using an ink with good lubrication, an effortlessness of moving the nib across the page. The colour is good but there is no shading or sheen to get excited over. Unfortunately Field Notes doesn't hold up under use but all of the inks in this series have bleed through and made the back side unusable. This ink will show up occasionally in my rotation, but it will be selected because I'm looking for a dark ink rather than a purple one.
