4 Colour Sticker Printing how CMYK builds every colour

CMYK printing guide

Getting the most from four-colour printing

CMYK is remarkably capable, but it has limits. Knowing both helps you design stickers that look right the first time.

Why choose 4 colour sticker printing?

Four-colour process printing places tiny dots of cyan, magenta, yellow and black side by side and on top of each other. From a normal viewing distance your eye blends them into a continuous range of colours.

Because every colour is built from the same four inks, a single design can contain photographs, gradients, shadows and dozens of colours without adding a separate ink for every colour. That makes CMYK ideal for illustrations, photo stickers and colourful logos.

It also gives consistency across materials and reorders, since the same colour recipe is used every time the file is printed.

What CMYK reproduces well

Four-colour printing excels at:

• Photographs – people, pets, products and landscapes.
• Gradients and blends – smooth transitions between colours.
• Detailed illustrations – artwork with many colours and textures.
• Multi-colour logos – brand marks with several flat colours.
• Earthy and natural tones – skin tones, woods, foods and foliage.

Materials and how they affect CMYK colour

CMYK inks are translucent, so the material underneath matters. White vinyl reflects light back through the ink and shows colours most accurately. Paper softens colours slightly as ink sinks into its surface.

On clear film, colours look lighter because there is no white base behind them, and the surface the sticker sits on shows through. On metallic film, the metal gleams through the ink and tints every colour with a sheen.

A gloss finish deepens colours and increases contrast, while matte finishes mute them a little in exchange for less glare.

Preparing artwork for four-colour print

Screens display colour in RGB, which can show brighter greens, blues and oranges than CMYK inks can print. Convert your artwork to CMYK before sending, and review how colours change, rather than leaving the conversion to chance.

Neon, fluorescent and metallic colours sit outside the CMYK range altogether. If your brand relies on a spot colour reference, send it and we will aim for the nearest CMYK match, or discuss a fluorescent or metallic material instead.

Set small text in pure black rather than a four-colour black, so it stays crisp. Large black areas benefit from a rich black build that looks deeper. Supply images at 300 DPI at print size.

How CMYK printing helps your brand

Four-colour printing means your stickers can show exactly what your brand looks like, including photography and complex artwork, rather than being simplified to a couple of flat colours.

Once your colours are set up correctly in CMYK, every sticker, label and reorder draws from the same values, keeping your brand consistent across everything you print.
