Fountain Pen Converter with Different Ink Color Change
Q:
If I have a fountain pen with an ink converter, can I use the same converter for different color inks? Do I have to clean the converter out when using a different color ink?A:
No, you do not need a new ink converter for each fountain pen ink color you use but you do need to clean the pen before using a new ink. Fountain pen inks are water based and over time the water will evaporate from the ink leaving only the dye or pigment and other particles behind. It is always good practice to flush a fountain pen when changing inks especially to a different color or a new brand of ink. If you do not clean the fountain pen prior to adding new ink it will mix the two inks as well as the properties and color of each fountain pen ink. Even if you were to use a separate ink converter with each ink you would still need to clean the nib, feed and the converter. If you were to remove the old ink converter from the fountain pen and store it the ink would dry inside the converter.

Fountain pens require more maintenance than ballpoint or rollerball pens but give you more freedom in ink choices as well as line variation. Fountain pens create a unique writing experience unlike any other writing instrument.
