What Pantone Colours Are and Why They Matter for Custom Printing

Pantone colours are a standardised colour identification system where every colour gets a unique code number, so a printer in London and a designer in Edinburgh can talk about the exact same shade without guessing. If you’re ordering custom printed t-shirts or workwear with your brand logo on them, Pantone is how you make sure that red is your red and not some random red that looked right on someone’s laptop screen at 2am.

This guide covers how the Pantone system actually works in garment printing, when you genuinely need Pantone matching (and when you’re paying for something that won’t make a visible difference), and how each print method handles colour differently. I’ll also walk through what we do in our East London workshop when a client hands us a Pantone reference and expects it on a t-shirt by Friday.

What Actually Is the Pantone Matching System?

Back in 1963, a chemist called Lawrence Herbert bought out a small printing division in New Jersey for $50,000 and renamed it Pantone. His idea was simple: create a universal colour language for the printing industry. Before Pantone, if you told a printer you wanted “blue,” you’d get whatever blue they felt like mixing that morning. Herbert catalogued specific ink formulas so that PMS 286 C means the same blue whether you’re printing in Stratford or Stuttgart.

The system now contains over 2,161 solid colours, according to Pantone’s own specifications. Each one is identified by a code — the number tells you the colour, and the suffix tells you the paper finish. “C” means coated (glossy paper, more vibrant), “U” means uncoated (matte paper, more muted). There are 14 base pigments, and every Pantone colour is mixed from those 14 according to a published recipe. That recipe is what screen printers use when mixing inks.

One thing that trips people up: Pantone also has a completely separate colour system for textiles called Fashion, Home + Interiors (FHI), which uses TCX codes for cotton and TPG codes for paper. When we’re talking about printing onto garments, the relevant system is usually the Pantone Matching System (PMS) with Solid Coated references — that’s what screen print ink mixing systems are calibrated to. If a client sends us a TCX code, we have to cross-reference it to the nearest PMS equivalent, and the match won’t be perfect because the dye chemistry is different from ink chemistry.

Pantone vs CMYK vs RGB — When Does It Matter?

This is probably the question we get asked about most, and it ties directly into our RGB vs CMYK guide for DTF printing. Here’s the short version of how these three systems relate to each other.

RGB (Red, Green, Blue) is how screens display colour. Your monitor mixes red, green, and blue light to create roughly 16.7 million colour combinations. It’s the widest gamut of the three, which is why everything looks gorgeous on screen and then slightly disappointing when you print it.

CMYK (Cyan, Magenta, Yellow, Key/Black) is how most printers work, including our DTF printer. Four inks get laid down as tiny dots that your eye blends together. The problem is CMYK can only reproduce around 16,000 colours. Sounds like a lot until you compare it to RGB’s 16.7 million. That gap is why customers occasionally email us saying “the blue on my screen was brighter.” Yes. It was. Screens cheat.

Pantone sits in an interesting middle ground. Each colour is its own pre-mixed formula, not a blend of dots. According to CorelDRAW’s Pantone guide, the Pantone gamut is larger than CMYK but smaller than RGB. The number that matters here: roughly 30% of Pantone’s 2,161+ colours fall outside what CMYK can reproduce at all, per Wikipedia’s documentation on the system. That’s about 1,100 shades where your DTF or DTG printer physically cannot match the Pantone swatch, regardless of how well the ICC profile is built.

How Screen Printing Uses Pantone Colours

Screen printing is the only garment decoration method where you can genuinely print a true Pantone colour. The reason is mechanical: in screen printing, each colour in your design gets its own screen and its own pot of ink. That ink gets mixed from base pigments using the formula in the Pantone book, same way a Dulux paint machine mixes a tin of emulsion from a colour code. One formula, one ink, one colour. Done.

In practice, a screen printer takes the Pantone reference (say PMS 186 C, which is a specific red that Coca-Cola uses), weighs out base inks on a scale according to the formula, mixes them, and loads that ink onto the screen. The result is a flat, solid layer of that exact colour on the garment. No dots, no halftones, no CMYK approximation. Just that red.

There are some real-world wrinkles though. ScreenPrinting.com’s technical guide points out that even a perfectly mixed Pantone ink will look different depending on the garment colour underneath. Pantone books are printed on white paper. Print that same PMS 186 C on a heather grey t-shirt, and the fabric colour bleeds through, shifting the shade. On dark garments, you’d lay down a white underbase first, but that tends to lighten the ink slightly.

Screen printers who work with Pantone matching regularly keep a couple of essentials: a current Pantone Formula Guide (the Solid Coated version — the one that costs around £150 from UK stockists), an ink mixing system like FN-INK or Wilflex, a gram scale, and a 5000K daylight-balanced light source for checking colours. Pantone actually recommends replacing your guide every 12–18 months because the printed swatches yellow and fade over time.

How DTF and DTG Printing Handle Pantone Matching

DTF and DTG printers do not use Pantone inks. Both methods use CMYK (plus white) ink sets, and the printer lays down tiny dots of those four colours to simulate the appearance of your design. This is fundamentally the same as how your home inkjet works, just optimised for textile film or fabric.

So when someone asks us to match a Pantone colour on a DTF transfer, we’re always approximating. The workflow goes like this: we take the Pantone reference, find its closest CMYK or RGB equivalent (Pantone publishes these in their Color Bridge guides), plug those values into the artwork, and let the RIP software and ICC profile handle the conversion.

For about 70% of Pantone colours, the CMYK equivalent is genuinely close — most people couldn’t tell the difference without holding a Pantone swatch right next to the print under controlled lighting. The trouble starts with the other 30%. Bright oranges, vivid greens, certain purples, and neon shades are the worst offenders. Pantone 375 C (a vivid chartreuse green) is notorious in the digital printing world — forum threads on Signs101.com are full of printers pulling their hair out trying to match it with CMYK.

What we do for critical colour work on DTF is print a swatch test sheet. We’ll produce a ring of colour tiles around the target shade — maybe eight variations stepping slightly warmer, cooler, lighter, and darker — press them onto a scrap of the same fabric, and have the client pick the closest match under decent lighting. That’s more reliable than any theoretical CMYK conversion. We cover our full colour management approach for DTF here.

Embroidery and Pantone: Thread Colour Matching

Embroidery is a different animal entirely. We’re not using ink — we’re stitching with thread, and thread comes in a fixed set of colours from manufacturers like Madeira and Isacord. Madeira Polyneon offers roughly 400 colours. Isacord 40 has a similar range. Compare that to Pantone’s 2,161+ and you can see the problem.

Madeira offers an official Pantone matching service under licence from Pantone. For each thread colour where a close Pantone match exists, they publish the reference. But as Madeira themselves note, there are plenty of Pantone colours where no close thread match exists. In those cases, you’re looking at the nearest available shade and having an honest conversation with your client about the gap.

In our embroidery work, we use Madeira Polyneon polyester thread and keep a physical colour card in the workshop. When a client sends a Pantone reference for their logo, we pull out the card, find the nearest thread, and stitch a test on a spare piece of fabric. Sometimes we’ll show the client two or three close options and let them pick. The good news is that embroidered logos are small — typically under 12cm wide — and the texture of stitching hides minor colour differences better than flat ink does. A thread that’s half a shade off usually looks fine once it’s stitched at 0.4mm stitch length into cotton piqué.

When You Actually Need Pantone Matching (and When You Don’t)

Here’s where I’ll be honest with you, because I think a lot of print shops oversell Pantone matching to customers who don’t need it.

The situations where Pantone genuinely earns its keep are pretty specific. If you’re running a chain — say 40 coffee shops ordering polos from one supplier and aprons from another — Pantone is the shared reference that stops your north London branches wearing a different green to your south London ones. Corporate clients ordering thousands of pieces across multiple suppliers need that consistency, and a Pantone number delivers it.

Same goes for retail-ready merchandise where the brand owner has strict guidelines. When Adidas sends you a brand pack with PMS references, they mean it. They’ll reject stock that’s visibly off-colour. And for screen printing one or two-colour designs where the colour IS the brand identity (a football club’s red, a university’s navy), Pantone matching is worth every penny of the extra cost.

But here’s the thing — most of our customers don’t fall into those categories. If you’re a small business ordering 50 printed t-shirts for a team building day, a hex code from your website gives us plenty to work with. We’re printing DTF anyway, so we’re in CMYK territory. Paying for formal Pantone matching gets you a reference number on paper, but the DTF print itself is still a CMYK approximation.

Same if your design is a full-colour photograph or anything with gradients and loads of colours. That’s process-printed (CMYK) by nature. Pantone is for solid, specific shades — it has nothing to do with photographic imagery.

And if you haven’t actually nailed down brand guidelines yet — if your logo colours are “whatever looked right in Canva that one evening” — save the Pantone conversation for later. Get the hex codes from your design file, tell us those, and revisit Pantone when you’re scaling up and working with multiple print suppliers.

How to Find Your Brand’s Pantone Colour

If you do want to pin down your brand’s Pantone reference, the best place to start is your existing brand guidelines. If a professional designer created your logo and identity, the Pantone codes should already be in there alongside the CMYK, RGB, and hex values. Dig out that PDF before you do anything else.

If that doesn’t exist (or the designer didn’t include Pantone), the next best option is a physical Pantone Color Bridge Guide. This book (around £200+ for the set) shows every Pantone colour next to its closest CMYK, HTML, and RGB equivalents. You find the page that matches your brand colour, read off the PMS number, and you’re done. Physical guides are always more accurate than any screen-based tool because your monitor isn’t colour-calibrated.

Pantone also has an online colour finder at pantone.com/uk/en/colour-finder where you can search by hex code or browse by colour family. It’s free and reasonably useful, but remember it’s showing you colours on your uncalibrated screen, so treat it as an approximation.

The free alternative that honestly works fine for most of our customers: just give us your hex code with a note saying “match as closely as possible.” For DTF and DTG printing, we’ll run that through our colour workflow and you’ll get a good result. For screen printing, we can use the hex as a starting point and tweak from there. No Pantone book required.

From Our Workshop: The Colour Matching Jobs That Caught Us Out

The Football Club That Changed Supplier Mid-Season

A local Saturday league club came to us halfway through their season needing replacement shirts. They’d had their first batch done by another printer and wanted us to match the red. They didn’t have a Pantone reference — just a worn, faded, sweat-stained shirt from six months of Sunday morning kickabouts. We pressed a few DTF test swatches against the shirt, found the closest match to what the colour probably was when new (not what it was now), and ran the order. They were happy, but it was a reminder that colour changes over time, through washing, UV exposure, and general wear. If they’d had a PMS number from day one, we could have matched the original specification rather than guessing from a knackered shirt.

The Corporate Rebrand With Twelve Different Blues

A marketing agency sent us brand guidelines for a client’s workwear order. The guidelines listed a Pantone reference (PMS 2945 C), a CMYK breakdown, an RGB value, AND a hex code. All four were supposed to represent the same blue. They didn’t. The Pantone was a deep, slightly greenish blue. The CMYK breakdown produced something warmer. The RGB was brighter (because screens). The hex code was different again — possibly from a web developer who eyeballed it.

We printed DTF test swatches of all four values, photographed them side by side under 5000K lighting, and sent the photos to the agency. Their creative director picked the one closest to the physical Pantone swatch, and we ran with those CMYK values. The lesson: when your brand guidelines have contradictions between colour systems, the Pantone reference is usually the master. Everything else should derive from it.

The Neon Nightmare

A streetwear brand wanted hoodies printed with a logo in Pantone 802 C — a fluorescent green that practically glows. They’d seen it on a screen-printed skateboard deck and wanted it on custom hoodies. The problem: they wanted DTF, and fluorescent colours are literally outside the CMYK gamut. CMYK inks can’t produce fluorescents. We showed them a test press of the closest CMYK approximation (which came out as a fairly bright lime green, but nothing like the eye-searing neon they wanted), and explained the options. They ended up going with screen printing for the logo colour, which let us use actual fluorescent ink. It cost more per unit and limited their print positions, but they got the actual colour they wanted. Sometimes the right answer is changing the print method, not fighting the colour science.

Frequently Asked Questions

Pantone matters when you need consistent colour across multiple print runs, suppliers, or methods. But for most of the jobs that come through our workshop — a batch of DTF transfers for a small brand, embroidered polos for an office, printed tees for a charity run — a hex code and a five-minute chat about what you’re expecting is plenty. We’d rather have that honest conversation upfront than charge you for Pantone matching you’ll never notice the benefit of.

If you’re at the stage where proper Pantone matching makes sense, we can absolutely work with your PMS references on screen print orders. And if you’re not sure yet, just tell us about your project and we’ll give you a straight answer about what’s worth paying for.
