Why Printing Light Inks on Dark Shirts Costs a Little Extra
When you’re organizing spirit wear for the school or coordinating field day shirts, budget is everything. We get it!
One question we hear a lot from PTA parents is: "Why does it cost more to print a white or light yellow design on a black shirt than printing on a light colored shirt?"
It isn’t a hidden fee or a penalty for choosing cool shirt colors. It actually comes down to a screen printing secret called the underbase. Here is the simple, behind-the-scenes reason why it happens, plus some easy ways your school can save money on your next order.
The Secret: Dark Shirts Need "Primer"
Think of screen printing ink like painting a wall in your house. If you try to paint a bright white or sunny yellow directly onto a dark navy blue wall, the dark background is going to bleed right through. Your white paint will look gray, and your yellow will look like a muddy green.
To prevent your school logo from looking dull, we have to print a primer layer first.
- The First Print: We print a solid white foundation layer (the underbase).
- The "Flash" Dry: We use a high-heat heater to quickly bake and dry that white ink so it hardens.
- The Second Print: We print your actual design colors perfectly on top of that white foundation.
Because of this, a simple "one-color" design on a dark shirt actually takes twice the setup time, an extra custom screen, and double the printing effort to make sure it looks bright, beautiful, and holds up in the family wash machine for years to come.
Pro-Tips for PTA/PTO: How to Save Your Budget
If you want to keep your costs down while still getting awesome gear for the kids and teachers, try these clever ordering hacks:
- Flip the Colors: Choose a lighter shirt fabric (like ash gray, athletic heather, or ANY lighter colored garment) and print a dark ink (like navy, black, or dark green) on top. No underbase needed, which saves you money instantly!
- Stick to One Ink Color: If you must have dark shirts, keep your artwork strictly to one single ink color (like all white). It still requires the underbase process, but it keeps you from paying for third or fourth colors.
- Consolidate Your Order: Screen printing gets significantly cheaper per shirt the more items you order. Combine the student shirts, teacher shirts, and volunteer hoodies into one single bulk order instead of splitting them up.
- Embrace the "Vintage" Look: Ask us if we can do a single-pass print without an underbase. The dark shirt will peak through the light ink a little bit, creating a trendy, distressed, vintage look that a lot of middle and high school students love.
