Why Every Designer Should Use Pantone for Print-Ready Colours

At Halo Print Co, we’ve printed tens of thousands of designs in our Sydney workshop. Yet one of the biggest mistakes we still see? Designers are sending RGB files to print and wondering why the final outcome looks nothing like what they envisioned.

Here’s the truth: your computer displays colour using light (RGB = Red, Green, Blue). Printers rely on physical inks (CMYK = Cyan, Magenta, Yellow & Key/Black). Because the mediums are completely different, colours shift,  sometimes dramatically, when you go from screen to print.

That’s where the Pantone Matching System (PMS) comes in. It’s the universal “colour dictionary” the printing industry uses to ensure what you see is what you get.

1. The RGB vs CMYK problem

Why your bright teal ends up as a muddy green

• On-screen: your design glows in RGB — vibrant, back-lit, dynamic.

• In print: you’re using inks that absorb light and are impacted by fabric, ink type, print method, lighting and more.

• When you convert RGB to CMYK (or send an RGB PDF straight to the printer), you risk major colour shifts — the teal you chose could become an entirely different shade.

Without Pantone, you’re guessing how your screen colour will reproduce. Not the best strategy when you’re building a brand or designing merch that matters.

2. What Pantone / PMS means for your print job

The secret sauce for consistent and professional colour

The Pantone Matching System gives us:

• A shared code everyone understands — you pick “PMS 326 C”, we know exactly what ink mix and printed result to deliver.

• A way to bypass the RGB-CMYK conversion headache: instead of guessing the print colour, you specify the Pantone number and we do the rest.

• Reliability for reprints: once you’ve nailed your PMS code, you can reorder months later and expect the same results.

When a client hands us a Pantone number, the job becomes predictable, efficient and professional. Otherwise, we’re playing colour roulette.

3. How to use Pantone in your workflow

Step-by-step to colour accuracy

1. Choose your colour on-screen, then check the Pantone swatch book (or Pantone App).

2. Match the Pantone number to your design file.

3. Set up your document properly in CMYK and/or with Pantone spot colours.

4. Provide the PMS number when you send artwork.

5. We confirm, mix, and print using the exact formula.

If you don’t have a Pantone book yet (yes, they’re expensive — but worth it), the Pantone App is a helpful alternative. Just remember: physical swatches are always the most accurate.

4. Why this matters for brand & merchandise printing

Because every colour tells your story

• Consistency = professionalism

• Correct colour matching = stronger brand recognition

• Avoiding reprinting mistakes = saving money and stress

Whether you're printing shirts, retail merch, or promotional products, Pantone gives you control over your final output.

5. Quick FAQs

• Is Pantone only for screen printing?

  PMS is heavily used in screen printing, but it’s relevant across multiple print methods like DTG, DTF, offset, embroidery, colour matching and more.

• Can I just send RGB and let you convert it?

  We can convert it, but it’s not exact. If you want control, give us your Pantone number.

Final thoughts

Don’t leave your colour outcomes to chance. If you want your printed garments, merchandise and apparel to come out looking EXACTLY how you envisioned, work in the Pantone universe.

Before your next order, grab a Pantone book (or the app), pick your PMS number, send it to us, and we’ll make sure your colours stay true.
