I did look at some staedtler red and some edding 3000 red through a cheap
microscope.
it did actually focus at x1000 and it was still no particles or such to be
seen.
i have no idea if i could actually see particles at this magnification in
a pigmented ink.
have no pen here that clearly says pigmented and so i have no comparision.
How large would those particles be?
(and would i see that at x1000? i know nothing about microscopes....)
well, a hair fills the whole viewing area at x1000
and it is about 50micrometer thick, right?
if make that x1000 it is 5mm... well, that could be about right..
( i guess this is the size of the image inside the microscope tube)
that means i could maybe distinguish particles of 5 microns, or less...
(maybe 1 micron).
lights wavelength is at 500nm that means 1 micron is a bit unlikely to be
seen in a plastic
microscope.... i dunno, never was good at optics...

The maximum particle size in the pigments is
about 0.19 microns and the Epson™ print head
nozzles are 25 microns plus or minus 5 microns
(it varies a little from one model to another).
The ink is filtered to 0.45 microns and does not
cause clogging. It stays in suspension. It is rare
for an Epson™ print head to clog, 99% of the so
called clogs are air/foam related problems, or a
lack of proper print head cleaning during and
after extended use.
so the heads are 25micron, which would fill half the viewing area in my
plastic microscope.
i should well be able to see if there are any particles in the ink which
do not fit through.
i could not see ANY particles, it was completely uniform (and it was
focused, i could see dust
enameled in the ink).
This tells me the staedtler red and the edding 3000red should fit through
a epson head
without problems.
Are there any ideas how to filter ink?
maybe if we have a pigmented ink we can just filter out anything above 0.5
microns too?
