Discover Sun Reveal Ink—the color-changing, sunlight-activated ink that makes custom tees stand out.

Sun Reveal Ink — The Shirts You Didn’t Know You Needed

You’ve done custom t-shirts before. But you’ve probably never seen one do this.

Enter Sun Reveal Ink — the specialty ink that adds a little bit of magic to your next order. Indoors? The design stays hidden in plain sight. Step into sunlight? Full-color art appears right on the shirt like it was waiting for the spotlight.

It's not just a cool trick. It’s the easiest way to take your custom church merch, camp shirts, or mission trip gear to a whole new level. Because let's be honest: your group deserves more than the same old logo on the same old shirt.

Why Sun Reveal Ink is the Coolest Thing Since Toasted Bread:

  • Color-Changing Magic
    Watch your design shift from minimal to full-color instantly when exposed to sunlight.
  • Super-Soft Feel
    Printed with our Super-Soft Water-Based Ink, on our Signature Super-Soft Tees — because wow-factor means nothing if the shirt’s uncomfy.
  • Built for Summer
    Perfect for youth camps, VBS, mission trips, and outdoor events where a little sun creates a lot of buzz.

How to Order Sun Reveal Ink Shirts:

1. Send us your design idea (or customize one of our ready-to-go templates).
2. Our team preps your design for print, optimizing it for Sun Reveal Ink magic.
3. You review and approve the final design.
4. We print & ship your shirts within 72 hours of approval.

FAQ: Sun Reveal Ink

How does Sun Reveal Ink work?
The ink is UV-reactive. Indoors, the design stays faint or invisible. In sunlight, it fully reveals your printed artwork.

Is Sun Reveal Ink only for white shirts?
Nope! It works best on lighter colors but can be applied to various colors depending on your design.

Can I combine Sun Reveal Ink with other specialty inks?
Absolutely. Many of our customers pair it with Water-Based Ink or even add dimensional flair with Puff Ink.

Is the shirt still comfortable with Sun Reveal Ink?
100%. All prints are done using our Super-Soft Water-Based Ink system, so the shirts stay breathable and soft, not heavy or stiff.

But what if none of the Sunday Cool Stock Inks match my design or logo? Nothing to fear! We can Pantone Match your ink to whatever code you’re needing to a 90% accuracy. 

There are a few requirements to qualify for a Pantone Match on your project:

  • Stick to our Super Soft Signature line of apparel.
  • The garment color you choose must discharge vibrantly, not vintage. If you need help determining which of our inventory items discharge at which rates, check out our blog post entitled Waterbased Print Results.
  • Your order must include 144 units or more. 

Additionally, we charge $25/match! This means if we need to match 2 ink colors to a specific code, it’ll be a $50 charge.

But how do I know which code to send you? Great question! Your organization might have a branding guide including all relevant codes and colors that set your group apart. OR you could send in your logo and ask us! Our talented Art Staff can color match the logo and tell you the code! We work often in the Pantone and HEX libraries!

Now Trending — Foam Trucker Hats

The Underrated MVP of Custom Merch

Everything you need to know before placing an order

Custom foam trucker hats are one of the most versatile, affordable, and memorable pieces of group apparel out there. Whether you're gearing up for summer camp, planning a conference giveaway, or refreshing your church's merch table, a well-designed hat can tie everything together — without breaking your budget.

But before you hit "Get A Quote," let’s break down what makes a great custom foam trucker hat, what to look for in a print partner, and why these foam-front classics are trending hard right now.

Why Choose Foam Trucker Hats?

Custom hats are everywhere. But foam trucker hats? They're in a league of their own — and for good reason.

  • They’re lightweight and breathable, making them ideal for hot climates, long events, and high-energy environments like summer camps or youth group retreats.
  • They have high visibility — literally and figuratively. A bold print on a foam front panel makes your design stand out in photos, on stage, or across the rec field.
  • They’re cost-effective. Compared to embroidery-heavy or premium headwear, foam truckers are easier on your budget.
  • They’re just plain fun. Custom foam trucker hats instantly add personality to your group, team, or brand.

What to Consider Before Ordering Custom Foam Trucker Hats

Before submitting your design, here are a few things to think through to make sure your order checks all the right boxes:

1. What’s the goal?

Are you ordering hats for a staff team? Volunteers? Conference giveaways? A mission trip?
Foam trucker hats work great for events where you want something eye-catching, useful, and easy to pack or distribute.

2. How many do you need?

Whether you're ordering a dozen for your youth leaders or a few hundred for an event, our 72-hour turnaround makes it easy to get what you need, fast. Foam truckers are especially great for bulk orders.

3. Do you already have a design?

Our most popular option is to print directly onto the foam front using full-color Digital Ink. That means more flexibility for your design and more vibrancy in the final product. Embroidery and custom patches are available to order as well.

Not sure what to print? Our team of world class artists can help turn your theme or logo into a high-impact hat graphic.

4. What’s your timeline and budget?

At Sunday Cool, our foam trucker hats ship out within 72 hours after artwork approval. No rush fees. No guesswork. Just a lickity-split turnaround.

How Sunday Cool Does Foam Trucker Hats Differently

Not all custom hats are created equal. Here's why Sunday Cool's foam trucker hats are trusted by hundreds of camps and churches.

  • Full-color printing with Digital Ink — your design prints crisp & vibrant.
  • Low minimums — order a few, or a few hundred*
  • Soft foam front with mesh backing — comfortable, breathable, and made to wear again
  • Printed in-house by real humans — not robots or drop shippers!!

We’ve printed thousands of these for churches, ministries, and events that wanted something a little more fun, a little more memorable, and a lot more wearable.

*orders start as low as 12 pcs

Can I see a proof before printing?
Always. We’ll send you a digital mock-up to review and approve before anything goes to print.

What if I don’t have a design?
No problem. Just give us a theme, idea, or logo and we’ll help you create something that looks great on a foam front.

Can we use our trip verse or location?
Absolutely. Every design is fully customizable—so you can add your destination, year, verse, or even your team members’ names if you want to get fancy.

Do you offer hats or other items too?
Yes. Foam trucker hats, woothoops, stickers, note jotters—you name it. If you want to take your mission trip merch to the next level, we’ll build a package that fits your needs.

What shirt colors work best?
Our most popular mission trip tees are in earth tones or heather brights (like Heather Sky or Heather Mint Julep), but you can choose from dozens of colors. We’ll help guide you based on your design and vibe.
