Using Dye To Make Ink


DiveDr

Recommended Posts

Sorry if I misunderstood. I was under the impression that "The dye is listed as non-toxic, all the colors, so probably a neutral aniline salt".

 

Of course, otherwise, there may be no reason to worry.

The photo flo is the surfactant in this ink (approx 60% water, 30% propylene glycol, 10% Triton X-100).

I'm interested in this equivalence. Would it be plausible to use Triton X-100 directly, rather than the Photo-Flo 200 combination? Would the above proportions give the correct amount to try as an equivalent?

 

It's interesting that propylene glycol is (among other properties) a humectant, that in larger quantities would prevent complete drying. That's probably not of concern in the tiny amounts used in ink, though.

 

Thanks!

OK, so here's my first attempt at homebrew ink to suit my particular pen/paper combination, inspired by Drive Dr.'s original post.

 

Trying for a dry permanent purple ink.

2020 01 18 10pm :

15ml glass bottle with plastic cone lid seal (I misremembered it as 20ml size)

glass eyedropper for glycerin

50ml plastic syringe to measure water

Mixed

18 ml Distilled water, grocery store grade

5 drops Glycerin, drugstore generic

1/2 tsp Blue Purple 810 MX dye powder from PRO Chemical

0 Photo-Flo (I didn't have any on hand)

Shook 20 seconds 3x

Left to sit overnight in ~50 F garage.

I don't have a pH meter.

2020 01 19 3pm :

Filter once through Starbucks sBCAB129 "Interactive Cup" filter paper from roll, in funnel, into clean 15ml glass bottle.

Call this "Composition 810 A".

Trial writing with Wanwou glass nib: super wet at first, but settles down to normal looking line.

Color is very dark and somewhat muddy, not the bright blue-purple I hoped for. Maybe too much dye. Swab looks rather pale on ColORite card.

Trial writing in Jinhao 992 (previously had BSB) writes slightly narrower line than BSB.

Trial writing in target pen Lamy 2000 with Mike Masuyama 0.7mm CI gusher -- looks decent, gives better linewidth variation than BSB 2:1 water on printer paper.

Trial writing on Tomoe River gives desomecent line variation, takes a very long time to dry, so probably still too wet / too much flow. Maybe too much glycerin.

Water restistance tests pending.

2020 01 20. 9pm :

Wrote with Composition 810 A on Tomoe River paper, using both Jinhao 992 and the target pen Lamy 2000, Mike Masuyama CI gusher.

Dry time: 5 minutes.

Tap water, 100 F.

Dipped up to line for 15 seconds, pulled straight up, placed on paper towel.

IMG_4489 shows setup; IMG_4490 shows just after removal (still wet).

Turned writing over and wiped against paper towel.

IMG4491 shows after wiping while still moist.

What I think I see:

Some ink washed away immediately. There was pale ink color in the water.

Some ink stayed in place. It was paler than before dunking but remained crisp.

Some ink redeposited, making pale halos.

For my purpose, this is not quite satisfactory. Although the writing remains, accidental smearing would be likely.

Observations? Suggestions? Thoughts?

Thank you for sharing the experiment with us.

Fountain pens are my preferred COLOR DELIVERY SYSTEM (in part because crayons melt in Las Vegas).

I found the Composition shown above still too wet-writing, so I tried diluting it.

 

Usage report:

 

I have been using "Composition 810A" diluted 1:1 with distilled water for nearly two months now at work in a Lamy 2000 (medium) cursive italic on a PfFP Tomoe River notebook.

 

Likes:

It's about as dry-writing as any nice-color ink I've tried in that pen, and better than most;

It remains legible after smearing;

The color is near what I wanted;

 

Dislikes:

It smears, especially with moisture;

It is not dry enough for the paper/pen combination;

It shades (while many find this desirable, in my work notes I do not);

The color is still just slightly grayish, especially in the pale-shaded parts;

 

Next try will be without glycerine.

 

Has anyone else tried the DiveDr simple basic recipe yet?

Another thing I'll probably try is adding some pH buffer to the mix. This risks precipitation, but if that doesn't happen it could help the color bond to the paper better and reduce smearing.

So haven't posted here and quite a while but have been diligently working on ink formulas. Also doing some chemical analysis on commercial inks. Dyes are most definitely the way to go. Commercial inks are definitely aqueous dye based with the exception of some pigment based samples that appear to be emulsified suspensions for the most part.

 

Have settled on pH balanced Proscion dye solutions with varying amounts of Photoflow and glycerine which produces excellent results. Really vibrant colors and yes, shading on good paper! Sample photos to follow and will give specific formulas if requested.

      @Texas42 Thank you. I myself have recently had the experience of cleaning out a Wing Sung 699, in which the iron-gall ink has been sitting for six months. No damage to the metal piston rod (whereas, in a Wing Sung 3013 vacuum-filler, it would have been corroded, turned green, and contaminated the ink in mere weeks), but there was a ring of colour at the far end of the barrel that wouldn't budge, and I found it impossible to unscrew the filling mechanism to clean the interior wall of the ink rese

      Dang. You are a great friend!   One comment as a relative newcomer would be within the cleaning section: issues/differences in cleaning vacuum filler, piston filler in addition to cartridge/converter. I just cleaned out my Pilot 823 and while it wasn't particularly difficult I was a little paranoid about the drops of water that I could not get out. Perhaps this is something you are already including.   Anyway, great project and very thoughtful of you. I know it's a project fo

      Ah Ruaidhri ya wee heid banger, you do indeed have an Irishman’s way wid dose words now.

      Hi Smug Dill,   Nice project.  If it were me, I'd cover stuff like: - nib types available, i.e. styles, materials (SS vs gold), flex vs nails; - filling systems (I love the "thingie" comment) and how once can use them in practice (e.g. fill cartridges with a syringe); - pen body materials and their consequences (pen not balanced of too heavy and big for the hand); - and, whilst you've made it clear that you do not like vintage pens, a discussion of these beyond "I d

      Thanks for your input! Yes, not putting wood in the list of body materials warranting a mention was an oversight. I love pens with wooden bodies, but my main concern, or chagrin, is that I have not come across a wooden-bodied pen with a wooden cap that seals well. Actually, there is one, but it isn't really wood per se: the Pilot Custom Kaede's maple body is resin impregnated. All other wooden pens I have can dry out while capped and undisturbed; that includes several Platinum #3776 models.
