Thickening ink
« on: December 15, 2013, 10:12:04 PM »
Got some really thin/runny plastisol. Aside from corn starch and flour, what are you guys using to thicken your inks that are too thin to make it more like a maxopake ink?

I have found Union Black to be more runny than I like so I mix it 50/50 with QCM Black which I find too thick on its own.  Result is a medium body Black.  Can you do something like that or is color matching an issue?

Short answer, most ink manufacturers sell a thickener..
For instance

Rutland Paste Thickener M 00333

Union Paste Thickener PLUS-9114

Cool. Thanks frog. Can't dc the job and the lines throughout the print are wayyyy to thin to do an under base of white for it to look good, so pfp of the same ink it must be. But I need it to have more body. Thanks.

Cabosil otherwise known as "fumed silica".  There are other amendments in ink that make it thick such as with an HO plastisol but adding some cabosil will help if it's just too runny.

Yes cabosil or aerosil powder. But it makes ink on matt side.
