is there a substance you can add to extend the volume of ink?

back when I did silk screening in undergrad, we were able to extend the volume of the ink by adding a clear ink (it looked like letterpress transparent white). Is there something for letterpress? I didnt’ think transparent white will do since you use transparent white to mix lighter color (at least according to the pantone book.

I prefer to mix my own ink based on my own mixes and sometimes I end up not making enough and would like to know how I can extend the volume without having to mix a batch again.

thanks

Maybe conditioner is what you need.

sorry to sound dumb, but what’s a conditioner and where can i get one?

It’s sold where most printing suplies are sold. Its purpose it’s to make the ink more “runny”, that is, less thick. But not supposed to dilute your color.
