Platinum Carbon Ink Notes The following is copied directly from Platinum and contains important information about using this ink. Carbon Ink uses pigmented ink in order to improve the water-resisting property, light stability and heat-resisting properties while normal Black/Blue Black ink is water-based with dyes. That is why the carbon ink is suitable for important documents such as official documents which need to be stored for a long time. Some people use the carbon ink to draw a rough design for a picture painted in watercolors or colored inks because carbon ink is run-proof. You should be careful, however, to deal with carbon ink in your fountain pen. Ultrafine particle carbon powder was included in the ink. Comparing to the ink water-based with dyes, it tends to be stopped up because particles are coarse. If you use your fountain pen with the carbon ink everyday, there may not come problems but in case you have long period to use the fountain pen, it will be clogged. It causes serious problem because it is not easy to clean the pen clogged with the ink and dried up. Here are some tips about using carbon ink in your fountain pen. (1) Please pull out the ink cartridge/converter you are using and clean the nib completely before you use the carbon ink.
