I have a habit of marking as I read.

But I want a colour that does NOT appear when I photocopy the article which has been highlighted.

Do the 2 yellows (Noodlers) fall into this category?

Other than yellow, what other colour doesn't appear in photocopies? There will definitely be some scribbling as well.

Do highlighter inks 'damage' FPs? As in clogging them up fast? I intend to use it in my VP <F> nib.
Anything I should watch out for ?

TIA

May seem like a stupid comment, but wouldn't you want to use a B or stub nib for highlighting?

I'm not sure about the yellow, but I have used the Noodlers Lightning Blue in my Pilot aeromatic demonstrator with no problems at all. I was still a little worried though, so I made sure to flush out the pen after 2 fillings. I don't know if it shows up on xeroxed pages.

Hmm I have to admit some ignorance here. I've never tried to use a FP ink which won't be seen when I photocopy something....
... but in the old days when I used to work at the university and copied a lot, I always used a green highlighter. Light blue was a slight substitute but black of course and red too were always visible. Green was best, never to be seen (as I remember).
So why not try out a light green, less so a blue-green.

PS. I don't have any green inks, otherwise I'd have done an experiment first.

Early photocopies could not "see" blue and so blue lines on pages did not show on the copy but today's machines, especially colour copiers, can pick up blue along with almost everything else.

I understand that you would not want to see dark grey shading on the copies where you had highlit some text on the original so the more intense blue and green highlighters are out. I do have the "firefly" from Noodlers and tend to use it in a medium nib pen to underline or circle some text rthat than cover it completely as a broad marker pen might. But, I don't recal noticing whether this showed up on photocopies.

Sorry, I'm actually not much help!

I use PR Buttercup (yellow) for highlighting. The color does show up on photocopies, however.

Both black and white photocopiers these days will pick up the entire photo spectrum, the only difference is what print method they use and whether its colored or not. The only thing I can think of is getting whiteness of the whale and diluting an ink untill its extremely light and than hope the photocopier isnt sensitive enough to pick it up. All in all though, I'd say photocopy the document and write all over the copy you've made so you have a fresh one to send out to other people.

Highlight with Blue Ghost. It definitely will not show up on photocopies. Review your notes using an Ultraviolet penlight. You will still be able to see the highlights even with the room lights on (probably not in bright sunlight, though -- I haven't tried that).

Oh , my fault, wrong choice of words.
A yellow felt highlighter would suffice for highlighting. It won't appear after photocopy.

I meant that I had to underline and write notes along the margins. In the end, the printed page will look messy and untidy. I was looking for such an ink that won't show up even after photocopy in such a situation, thereby producing a 'clean' photocopy of the notes before scribbles.

I have Noodler's Year of the Golden Pig and the green highlighting ink (can't remember the name right now). Both show up as gray in B&W photocopies.

When you use ink to highlight, do you mark over the original text like a felt highlighter or just underline the text you want to highlght
