Colour in Screen Printing: 10 Questions Brands Ask Before Ordering Custom Prints
Getting colour right in screen printing isn’t just about choosing a nice shade on a screen. It’s a balance of design knowledge, print expertise, ink behaviour, and garment choice. At 1WorldPrint, we speak to brands, businesses, and creators every day who want their printed clothing to look exactly how they imagine it.
To help you get the best possible results from your next print run, we’ve answered the 10 most common colour questions we’re asked about screen printing.
Whether you’re ordering branded workwear, event merchandise, or retail-ready apparel, this guide will help you print with confidence.
1. What’s the difference between RGB and CMYK in screen printing?
RGB (Red, Green, Blue) is a colour system used for screens — phones, laptops, tablets and TVs. It works by emitting light, which is why colours often look brighter on screen.
Screen printing, however, uses physical inks, which follow a subtractive colour process like CMYK (Cyan, Magenta, Yellow and Black). Because ink absorbs light rather than emitting it, some colours simply can’t appear as vivid as they do digitally.
2. How do you get bright colours on dark garments?
Printing onto dark clothing usually involves a technique called white underbasing.
A white ink layer is printed first, creating a neutral foundation for the colours above it. This stops darker fabric tones from dulling or altering your design and ensures colours stay bold and accurate.
Think of it like painting on white paper instead of coloured card — the difference is huge.
3. Why does my printed colour look different from what I see on my screen?
This is one of the most common (and understandable) concerns.
Screens are backlit and vary wildly in brightness, contrast, and colour calibration. Two devices can display the same colour very differently. Printed ink, on the other hand, reflects light naturally — so it will never look exactly the same as a glowing screen.
To avoid surprises, 1WorldPrint uses standardised colour systems, such as Pantone, rather than screen visuals alone.
4. How can I make sure my colours are printed accurately?
The best way to achieve consistent colour results is by using Pantone (PMS) colour references
Pantone colours are internationally recognised and numbered, removing guesswork from the process. When you specify a Pantone shade, everyone — from designer to printer — knows exactly what colour is intended.
At 1WorldPrint, we regularly match Pantone colours to maintain brand consistency across garments and print runs.
5. Can gradients and shading be screen printed?
Yes — gradients and tonal effects are possible using a method called halftone printing
Halftones break images into tiny dots that vary in size and spacing. From a normal viewing distance, these dots blend together to create smooth gradients and shading.
This technique requires careful artwork preparation and experienced screen setup, so working with an established printer makes all the difference.
6. What does colour fastness mean?
Colour fastness refers to how well a printed colour resists fading, bleeding, or wearing over time. This includes exposure to washing, sunlight, friction, and everyday use.
High-quality inks, correct curing temperatures, and proper garment care all play a role in keeping prints looking fresh. Simple steps like washing inside-out and using cooler wash cycles can dramatically extend print life.
7. What is colour separation in screen printing?
Screen printing works by printing one colour at a time. Colour separation is the process of breaking a full design into individual colour layers, each printed with its own screen.
For example, a five-colour design requires five separate screens, perfectly aligned to build the final image. Clean, accurate separations are essential for sharp edges and professional results.
8. Does garment colour affect how my design looks?
Absolutely.
Ink behaves differently depending on the colour of the fabric underneath it. Light inks printed directly onto dark garments can appear muted or tinted unless properly underbased.
This is why choosing the right garment colour — and printing method — is just as important as the artwork itself. Our expert account managers are more than happy to advise and pass on their years of experience.
9. What are metallic and fluorescent inks?
These are speciality inks used to create standout finishes.
Metallic inks contain reflective particles that produce a shiny, chrome-like effect — ideal for premium branding or statement designs.
Fluorescent inks absorb UV light and emit intense brightness, making colours appear almost neon. They’re perfect for events, nightlife, and high-impact promotional clothing.
10. Can the same screen be reused for different colours?
In most cases, each colour requires its own screen. However, if you’re printing the same design in multiple colourways, screens can be reused after thorough cleaning.
That said, frequent colour changes slow production and may not always be the most cost-effective solution for larger orders.
