@etuomaala For the record, if you posted multiple images, they're not visible to me on Mastodon. When I've done the opposite, posting to Lemmy with a Mastodon account, multiple photos aren't visible to the lemmy users either.

etuomaala,

Oh, neat, Mastodon! I didn’t know for sure whether this was reaching Mastodon. I only posted the one image. I didn’t know I could post multiple images. Now, I know not to try, for compatibility reasons.

filled with a mix of water, Platinum carbon black, and inkjet printer ink

why do you choose 👆 solution over a commercial ink?

etuomaala,

I like changing colours a lot.

merde,

i need more information :) you can change colours with inks too

etuomaala, (edited )

Yeah, I was looking for a good CMYK fountain pen ink set. Nobody seems to make such a set. I could get a lot of half-solutions that would kind of work, but nothing beats the colour space coverage of a complement of CMY inks that were specifically designed to cover the whole colour space. They’re also about 10 times cheaper than fountain pen ink.

(And I got my printer ink for free on top of that from a print shop that just discontinued sales of their manual printer ink refills. The shop was Prink in Oulu, Finland. They probably still have these free refills.)

About six drops of ink and water the rest of the way gives you an entire cartridge of ink. This stuff is super concentrated.

I would use printer ink for the K too, but that’s too much of a crapshoot. Too often, the K is pigment-based, and that is likely to ruin a fountain pen. And it’s easy enough to find a good neutral black fountain pen ink. That is what the Platinum carbon black is for. It’s actually even more concentrated. Just one drop of it divided between two refills makes about a 50:50 grey that I can further modify with the printer ink. For less grey I have to go all the way down to one drop every four refills.

merde,

are you using distilled water or tap?

etuomaala,

Oh fuck, should I use distilled water? lol hm… Well, I’ve used tap water and so far, so good… You think I need to use distilled water, @merde ?

There’s minerals and other things in tap water. These things will cause issues and damage.

Though, the Lamy Safari is a cheap enough pen to not worry about buying a new one after causing damage.

However, there are other considerations for not using printer ink. Printer ink is designed to be used on specific paper, while fountain pen ink is designed to be more versatile.

The colors for fountain pen ink are also more than the base color. There’s the shading which can be a different color from the base The sheen, which can make the ink shine a different color in different lighting. It’s designed to flow properly through the feed with an appropriate level of viscosity. There are a lot of factors and testing that goes into fountain pen ink. You can read more about it here: www.jetpens.com/blog/…/968

etuomaala,

Hm. Thanks for the link. This could help me with my ink mixes. Oh, one thing that annoys me: I wish I had pure CMY dyes without surfactant in them, so that I could change the surfactant level and not make the ink so god damned bloody. But I have no fucking clue where I could find CMY dyes without the surfactant.

merde,

not a “should”, but it would help the nib, i assume, considering the state of the kettles and washing machines &c

it depends on where you live and the quality of the tap water 🤷

This is just pure chaos. Why would you use printer ink in a fountain pen? I cannot fathom any valid reason besides just wanting to do something batshit insane.

Printer ink is useful because each of the C, M, and Y inks is a perfect filter of exactly one colour. C filters red, M filters green, and Y filters blue. Commercial fountain pen inks almost never have this kind of absorptive specificity. They’re usually a mix of two or more dyes—a mix that you don’t control. Once a dye is in the mix, you can’t just take it out. The best you could do is dim all of the other colours, but then you lose saturation.

Here’s a specific example. Suppose you have a commercial ink of 5C:1M and you want pure C. You’re stuck with that 1M. The best you can do is add 1Y to make 5C:1M:1Y = 4C:1K. You’ve got a balanced C, but that extra 1K is going to make everything look a little grey. Ew. And that is assuming you can even get pure Y in the first place. No ink manufacturer in their right mind would try to sell a pure Y on purpose. It is very difficult to read. (Except under a pure blue light. It’s super awesome actually. This has been an underhanded privacy-invading tactic of the government for some time now. Yellow microdots are printed on all commercial inkjet printouts.)

These inks have also been designed to be mutually equally absorptive of their respective light wavelengths, so an equal ratio of 1C:1Y makes a perfectly balanced green. These inks has also been designed to stay in solution even when mixed. There are no chemical reactions that could cause precipitate to form, thus totally fucking the pen. Achieving this with commercial fountain pen inks would be difficult, and potentially dangerous.

However.

That’s actually not the reason why I started using printer ink. I was in Oulu, I had just run out of fountain pen ink, and all I could find was a print shop. Here is the whole story of my Oulu trip.I did a little research online before actually doing it. Other people have done it before. You just have to make sure to use dye-based ink and not pigment-based ink. I was able to confirm from Timi that it was dye-based. And prepare for the possibility of having accidentally turned your pen into an ink firehose because printer ink bleeds like three motherfuckers. It needs at least three parts water to calm it down.

EDIT: whoops, wrong blog post.

I get the theory of wanting to use CMY inks. I just think it’s weird and a lot of extra work for such a narrow goal. There’s not really any wrong way to use your pens however you want, provided you’re aware of the risks and know that you may be spending more time than it’s really worth.

Computer scientist here. I also write with a fountain pen.

Me too, is this a thing?

@vext01@lemmy.sdf.org avatar

Maybe, maybe not. Of the people I work with, only a handful even have a notebook. One other uses a Kaweco Sport FP. So for my sample, it’s a mixed bag.

Dhar, w A slightly eccentric physicist's EDC

That pen isn’t inked, you can see right through the ink window

etuomaala,

Yeah, I know. Like I told the other guy, it’s a stock image. An image of the real pen wouldn’t add anything except ink in the window, and I can’t take a better picture than whoever did the stock image. The ink in the window looks entirely unremarkable.

/me looks at ink in the window for five minutes with a bright light backlighting the window.

Yeah, the ink in there is entirely unremarkable. It’s just grey air bubbles and black water. IDK, you want a picture of the ink window anyway?

curiousaur, w A slightly eccentric physicist's EDC

I’ve used the same Lamy Vista, the clear acrylic version of this pen so you can see the ink color, for maybe 18 years. Absolute workhorse.

etuomaala,

OHHHH, I want that pen. I noticed it the week after I got my Safari, and was like, “NOOOOOOOOOOO!

curiousaur,

Especially with the converter with the red twist cap, it looks awesome.

thantik, w A slightly eccentric physicist's EDC

Nice, I’ve got the OG PinePhone. It had some circuit board issues, but I loved helping at the ground floor. Is the PPPro good enough to daily drive yet?

I also keep a USB, but with my Keepass database so that it’s an offline carry. I keep 2 copies additional to that, 1 in my fire safe, and 1 in my mothers fire safe.

etuomaala,

If you don’t mind living without a camera, yes. I think I might be able to get the camera working, but it hasn’t been a priority, because I never used my phone’s camera that much even before I switched to the PPPro.

thantik,

Nice - I never really use my camera anyways, so that’s great to hear.

etuomaala,

Now, though, people want a picture of the rock, and I’m like …shit.

fujiwood, w A slightly eccentric physicist's EDC

I only see a pen and part of a spiral notebook.

etuomaala,

That’s a stock image. Better than I could have taken, and the pen is identical.

Alkaseltzer028, w A slightly eccentric physicist's EDC

Okay, can you show us a writing sample? And what kind of ratio do you use when making that ink-mix?

etuomaala,

30 water : 1 platinum carbon black : 5 yellow : 5 magenta is the mix for octarine.

But seriously, 30 water : 1 platinum carbon black : 10 printer ink is a good starting point for mixing. That is about how sensitive the mix is to each type of ink. Pure printer ink won’t ruin the pen, but it bleeds like a motherfucker. If you don’t care about the next five pieces of paper, though, you can do some pretty cool stuff with it.

Vaginal_blood_fart, w A slightly eccentric physicist's EDC

You carry all this shit on rounds? I carry a pen.

transientpunk,
@transientpunk@sh.itjust.works avatar

Why would a physicist go on rounds?

Vaginal_blood_fart,

Because I’m a moron and misread this. Hahah

Empricorn,

To square things up.

Ashelyn, w februrary IT guy pocket dump

Is that a Warby Parker glasses cloth?

hamtron5000,

lol, yes it is! I got my glasses from there ages ago before I knew there were cheaper options. I like my glasses and need lens cleaning cloths all the time, so it works.

Ashelyn,

I thought I recognized the lettering through the backside of the cloth! When I got my prescription updated I decided to buy a “nice” pair of Warby Parkers and a couple swapout/“fun” frames from Zenni. Maybe it’s a bit consumerist but I like having a couple options to accessorize with depending on the overall look I’m going for.

intensely_human, w februrary IT guy pocket dump

Dude men’s pocket’s are huge!

survivalmachine, w februrary IT guy pocket dump

You can tell you’re either an IT guy or a professional skateboarder if you have pockets big enough to hold both a nalgene bottle and a coffee tumbler.

CodingCarpenter,

This also goes for any dads over 30

baltakatei,

If you have room for the state of New Jersey, you have room for a Nalgene.

grabyourmotherskeys, w februrary IT guy pocket dump

Handkerchief users represent.

hamtron5000,

it’s so handy. 99% of the time I use it to clean my glasses, but if I’m with someone who’s crying, if I need to clean off a screen, if something’s dusty or gross but I need to pick it up, if I get sweaty and need to wipe my brow, if something gets spilled and there are no napkins handy, etc I can use it. when my dad passed I got all his; he was a high school principal most of his career and carried one every day.

its_the_new_style, w februrary IT guy pocket dump

What kind of Subaru?

hamtron5000,

Ascent for business, Outback for pleasure, lol. the Ascent is the car I drive for work, the Outback is my personal car.

scytale, w februrary IT guy pocket dump

Hey fellow subaru owner!

hamtron5000,

good eye! my own car is an Outback (2018) and my work car is an Ascent (2022).
