Ipl (Ink Per Line)

[Consulting_Detective]

Something that I noticed that I ought to share with the fellow members of the FPN!

 

During my normal day, I carry my Lamy and Monteverde, both with Fine nibs, and both get adequate writing... but I noticed that my monteverde uses up more ink that my Lamy...

 

I write the same way, on the same paper, with the same pressure and ink... so I'm wondering does certain pens use more ink than others even if they have the same type of nib, and I even looked at the feeds of the pens and they both have the same width...

 

I'm just really curious if the Miles Per Gallon idea can be applied to pens, but be renamed to "Ink Per Line"?

 

Essentially, a rating system on how the efficient the pen is with different types of inks, hand writing pressure, paper and etc.

 

I already know the width, nib, and function of the pen will ultimately rule... but, as I said before, what if...

It would be ink per page.

 

The the nib and feed that controls the ink flow.

 

The ink it self will control how much goes down.

 

The Feed - C/C hole controls how much does go down.

Ah yes, ink per page is better name for it, but still, I have two monteverde's .. both with fine nibs, both using Parker Quink Black.. on same grade paper... used almost all the time, every day... and yet.. my jewelria gobbles up ink faster than my Invincia..

I have seen this general idea discussed here before, I'm pretty sure, but it seems that it's hard to get reliable data. Or perhaps I should say that it would be boring and laborious to acquire reliable data. I can observe that some of my pens last noticeably longer with a given amount of ink than others, but I haven't really quantified it. Once or twice I did note the approximate number of journal pages that I filled with a particular pen from full to empty.

 

This sort of thing is probably much easier to measure with ballpoint refills, where I have seen figures for the supposed distance of a continuous line written with one from full to empty. I don't know how accurate these are, they may be used as much for advertising as anything, but at least it's plausible that you can get a good measurement. With fountain pens, with their variety of nibs, feeds, and the factor of the absorbency of different papers, it would be a lot more complex. With experience, you get an idea how long you can go between refills on the pens that you use, and perhaps you learn to bring at least one backup.

2 nibs could write a similar width line, but one puts down more ink (is wetter) than the other.

So, the wetter pen will use up more ink than the dryer pen.
