How to make black cartridge ink more darker ? -

How to make black cartridge ink more darker ? I refill it at home. Can I add something to ink ?

Absolutely do not add anything to the ink. The best thing you can do is make sure you are printing on quality ink-jet paper; its designed to handle wet inks.

Whatever you do ... don t add anything to the ink. You could damage the print heads. Play around with the print quality. That is your best bet beyond buying better (more expensive) ink. Good luck!

Get higher quality ink refills. Or get whiter paper so it looks darker ^_^

when u want to print a page in your printer window select preferences and chose the best quality.
