Dark Garments vs. Light Garments: Why Is My Quote Different?

You might notice that printing on a black t-shirt costs more than printing on a white one. Is it a "cool tax"? No. It’s entirely about the labor and ink required to make the design visible.

Printing on Light Fabrics (The Easy Path)

When we print black ink on a white shirt, the process is simple:

1. Screen goes down.

2. Squeegee pushes ink.

3. Done. The white fabric acts as the brightness source. The ink soaks into the fibers slightly, leaving a very soft feel ("soft hand").

Printing on Dark Fabrics (The Challenge)

Try coloring on black construction paper with a yellow marker. It vanishes, right? You need white paint first. Screen printing is the same. To print yellow on a black shirt, we must:

1. Print a White Underbase: A layer of white ink shaped like your design.

2. Flash Dry: Partially cure that white layer so we can print on top of it.

3. Print the Yellow: The yellow sits on top of the white, making it pop.

The Consequences

1. Cost: You are essentially paying for an extra color (the white underbase) and an extra step (the flash). This adds time to production.

2. Feel: The print will be thicker. You have two layers of ink instead of one.

3. Discharge Printing (The Alternative): For a softer feel on darks, we can use Discharge Ink. This bleaches the dye out of the shirt and replaces it with pigment.

   • Pros: Zero feel (soft hand).

   • Cons: Only works on 100% cotton; results can vary unpredictably on certain shirt colors (like royal blue or kelly green). Costs More

Summary: If you want the softest, cheapest print, go with dark ink on light fabric. If you want the "rock & roll" look, go with bright plastisol on black fabric—just expect a heavier print
