Filtering inks when filling ink cartridges for printers (a mixture of solvents, pigments, dyes and resins) requires the removal of particulate above 10 micron to protect the dispersion nozzles on the printer from blocking.
A similar process is applied for inks used for writing pens as well as inks used in decorative panelling used for instance in the automotive industry. The majority of ink producers use polypropylene or glass fibre pleated cartridges at 1 micron or below to give an excellent finish.
