Permanent Inks Or, Anti-Check Washing Inks?

[sidpost]

What are the better inks to use writing checks that are difficult to "wash"? I assume no waterbased inks are appropriate. What are some common easy to source brand names to consider? I'm not overly picky on color but have a preference for blues that are hard to photocopy accurately. I'm trying to move away from Industrial Sharpies.

 

TIA,

Sid

I'd suggest looking at the Noodler's "bulletproof" inks, although Noodler's is one of my least favorite brands. Goulet Pens has a chart that lists the properties of the Noodler's line. I use Heart of Darkness for check writing, but I don't recall if it's totally bulletproof or not.

Several brands offer bullet-proof inks.

All water based.

Back in the day they used an Iron Gall ink or Registrars ink. Those are still available but also Noodlers makes several bulletproof inks that can't be washed by water or chlorine.

Nano-carbon inks like Sailor Sei-boku, Sailor Kiwaguro, and Platinum Pigment blue are waterproof. Iron gall inks like Diamine Registrar's ink and Rohrer & Klingner Salix are also waterproof. With some of the iron-gall inks that are not blue-blacks such as KWZ IG Turquoise the non-iron gall componenet will run, but the iron gall part will remain, so even with those it would be clear that the writing had been tampered with.

Montblanc Permanent Blue is ISO 14145-2 rated document-proof ink.

 

It also shades very nicely!

Noodler's (bulletproof) Black seemed to have started it. Noodler's now has a range of bulletproof and forge-resistant (they change colour when fiddled with) inks. These are all dye-based inks that chemically react with the cellulose in the paper.

 

Pelikan, Sailor, Dr Ph. Martin, Blackstone and Platinum all have inks based on carbon pigments. As a technology, these are the oldest inks (used by the ancients in Egypt, Middle East greater India and the Chinese Empire) but their modern incarnations are all very good, and very FP safe inks.

 

There are also Blue, Blue-Black and Red pigmented inks made by Sailor, Dr. Ph. Martin and Platinum.

 

Mont Blanc, Koh-i-noor and De Atramentis (and there may be others) make FP ink that are, as carlos.q said, are Document Certified to be resistant to common forms of removal.

 

The iron-gall inks are permanent in that they deposit particles of black iron oxide in the paper, similar to the carbon particles deposited by the carbon inks. However chlorine bleach fades those particles to a light beige (almost invisible) colour.

 

Easiest and simplest in the US would be Noodler's Black.

Cheapest is Koh-i-noor Document Black and Document Blue.

That is a nice one! I'm glad you brought it to my attention.

Thank you! I'm going to give both these a test run. They appear to be a good everyday alternative for me and as noted, seem to be a good value oriented choice.
