Hi thre, have been wondering if thre is a way I could print a full color image using different inks (not using plastols inks)

What ink do you wish to use? You might use water based.

But this is a more complex piece of art and would likely be done as simulated process or perhaps even an index separation. If you do not have experience with this type of artwork it would be best to send it out possibly. This involves halftones which will require RIP software to accomplish.

Thanks Jonathan
Am not used to print such artworks, but I was also thinking if could use water based inks! And thanks for your help in this, I will try to play around with it until I come up with a complete work.

I know that probably wasn't much help but you're welcome

Artwork takes time to learn and it's good to start simple and build yourself up. But many dive right in more complex stuff and do okay with it too.
