speedball fabric screen printing ink

[anardana.livejournal.com]

Hi ladies,
For those of you who have made screen prints on clothing with speedball: how do you get rid of the shininess? I printed the design, and some spots needed touch-ups- and after I did that with a paintbrush (and let it dry) those spots are shiny while the printed part is normal matte!
I've ironed it already, too. My only theory is that those touched-up parts are thicker and need to be ironed longer?

thanks for any help! I don't want my design to be splotchy!
