Writing on transparency film

[plateaugal]

Is there any ink that one can safely use in fountain pens, as well as any type of transparency film that will accept it? I would so much like to use my fine pens when writing via overhead projectors, and not those smelly, coarse markers.

My guess it that any transparency film with a FP-friendly surface wouldn't be transparent anymore (FPs don't work on a smooth surface). I could be wrong, though.

I think the paper needs pores in order for the ink to soak into. That makes sense to me, why it takes longer for ink to dry on slicker paper.

 

I know when I have used markers on transparency film before, the thinner markers always beaded up but the broader markers left a decent line. So MAYBE if you used a broad point and fast drying ink, it MIGHT work.

I expect transparency film made for inkjet printing would also accept ordinary ink from a fountain pen. The two inks are similar enough that inkjet inks sort of work in fountain pens; both are water based dye solutions, so a coating made to accept and hold ink jet droplets ought to take a line from a fountain pen. I doubt a fountain pen line will show as anything but black, however; it's both significantly finer and quite a lot denser (in terms of dye laid down) than the line from the markers normally used for this. I also wouldn't expect to be able to erase fountain pen completely, the way you can when writing with wet erase markers on acetate sheets; not only don't most fountain pen inks wash out completely without considerable effort, but the coating on inkjet transparency sheets will tend to hold the ink.

 

BTW, it shouldn't matter (other than to make the screen image darker) if the film has a textured or frosted surface; it'll still be dark or colored ink on a light ground.
