That's great... another tip is to look into the clear tint/gel inks or clear-bases where you can add a color.... but even the clear-gel inks will create the opposite effect.... on lighter colored garments you can use a 1-screen with clear ink to get a darker-colored area of the shirt-color where the imprint is, and works on other colored garments without changing inks out.... each lighter-colored garment will have the print as a darkened "wet-looking" sort of deeper shade of the garment-color. I worked with these inks before and you can also use them to create tinted clear-black inks that help with soft shading over colors, etc. Like discharge on darks but in the opposite sort of way.
