Surprised by Parker Quink water resistance

[carlos.q]

In my ongoing search for safe, well behaved water resistant inks I decided to take a look at Parker Quink "permanent" blue and black. The permanent blue I had to import from the UK while the permanent black was easier to get. The results were surprising. Here is an "after" scan (I forgot to do the "before" scan :redface:):

As you can see, though the inks are not waterproof, they have some degree of water resistance. Quink blue leaves a legible light blue line while Quink black leaves a legible dark blue line.

The test was done on 20 pound printer paper, with a 10 minute drying time for the inks and a 1 minute blast of water from the faucet.

I'd be very interested to find out how water resistant the Parker Quink Permanent Red is... Don't suppose you've got some handy?

Sheaffer permanent inks behave the same way, although coffee and tea, as well as some other beverages will wash them out completely.

Sorry... I don't have Parker Quink Permanent Red...

I don't even have the more common Quink Blue-Black which I gave to a friend some time ago, together with a Lamy Safari.

A nice review and these inks are very underrated, aren't they? We tend to forget them.

I have two versions of Quink blue black. One washes out; the other one leaves a dark grey.

Inks behave differently to wetting when they are on the pages of a book vs. held under running water. Hard vs. soft water also makes a difference. I wrote in a composition book with about 30 of my inks and then soaked it in rain water for two weeks (until it began to smell bad). Some inks just feathered out into a big stain; others printed through a couple of pages in both directions; some feathered the color away and left grey writing; some remained unaffected. We should know these things when we want to protect our journals from floods or water damage following a fire. Problem is, ink manufacturers change their formulations at whim without telling anybody.

The old permanent blue became more permanent after a while... leave it to dry for 4-5 days and your results may be different

Parker Quink Black was my go-to ink for several decades, and it survived a number of coffee and water spills.

Problem is: there are at least 3 versions of that. One has Solv-X, one is composed of many different colors, and one is just black. They wash differently.
