An overview of the inks within this review series is available here. Let's start out by agreeing that for the most part, yellow inks are useless for journalling or correspondence and have almost no use in the workplace beyond highlighting. This was brought home to me when my wife peaked over my shoulder and asked "Are you writing in invisible ink?" to which I answered "Pretty much." If you follow the link to the brand overview (which you should) you will read more about the mixing of this line of inks. Let's just leave it at; yellow needs to be mixed. Full stop.
Where To Buy (No Affiliate Links)
Bleed Through: Yes the ink bleeds through on absorbent papers but the colour is so light that it has no affect on the use of the second side of the sheet.
Show Through: Absorbent papers exhibit show through but due to the colour, there is no real distraction associated with this show through.
Saturation: I'm not sure that a colour that is this light can be considered saturated.
Water Resistance: 100% waterproof. Amazing.
Drying Time: Longer than average dry time, 25 seconds using an EF nib on Rhodia.
Flow: Average flow. Average lubrication.
Colour Make Up
The only colour is the yellow pigment.
Similar Inks (Images Courtesy of Goulet Pens)
I am a bit conflicted naming similar inks because the other two inks will have none of the permanence properties of the De Atramentis Document Ink.
I can't recommend buying this bottle for writing purposes but if you are into sketching and other art endeavours I could see it having a place in your tool kit, especially if you mix it like was shown in this blog post. Will I be buying it? No, but my artistic side doesn't advance much beyond stick figures.
Other Reviews For This Ink
I reached out to Goulet Pens and asked if they would be willing to supply samples of the complete line of De Atramentis Document Inks. While they were out of stock in the Black and Brown variants, they kindly provided samples of the rest of this line to me free of charge. I do not feel that my opinions of this ink have been affected by receiving the sample for free.
