Waterproof printing Pixma i6800


Hey, I have windows 10 and just bought a Pixma i6800. I need to print black line on watercolor paper to watercolor paint over. Problem is, the ink is smearing and it doesn't matter if I print the black lines normal or on greyscale. 


Is the PGBK ink waterproof and if so, is there a way to specify it? 


If not, is there a black ink for this printer that is waterproof? 


Really need help on this because I bought this for my business to finally be printing myself and now I'm back at square one.. 😞

Hi Lhiggin,


The inks for your PIXMA iP6820 are not waterproof.  What most users do is coat the paper after printing is complete with a spray.  An example of such a spray coat is called frog juice.
