Why Colour Depth in Wide Format Printing Makes All the Difference

Colour depth is one of the biggest factors in how wide-format print is experienced. It is often the first thing people notice and the detail that gives a graphic real impact. Exhibition pieces, retail displays, vehicle graphics and premium posters all rely on strong, confident colour to carry their message. Not every printer is capable of delivering that level of depth, and the technology behind the machine plays a large part in the final result.

At GDS, we work with a wide selection of wide-format printers, each designed to offer its own strengths in colour reproduction. Understanding how these technologies behave helps customers choose the right solution for the work they produce.

How different wide-format technologies handle colour

Wide-format print covers a broad range of machines. Each uses its own method for placing ink, drying it and interacting with the material beneath it. These differences have a significant effect on colour accuracy, vibrancy and overall appearance. The following categories give a clear picture of how colour behaves across the main technologies that customers encounter.

Latex printers and their clean, versatile approach to colour

Latex printers are known for their flexibility and environmentally considerate design. They perform well across a wide range of substrates, including vinyl, fabrics, posters, and display films.

Their colour strengths include smooth tones and reliable vibrancy on coated media. Latex ink dries quickly, holds up well indoors and outdoors and delivers a clean, consistent finish. The ink sits on the surface more than it absorbs into it, which gives clarity but can sometimes reduce the depth of darker colours. Blacks may feel softer, and highly saturated tones can appear slightly less bold than in solvent or UV printing. Latex is ideal for everyday graphics and signage where consistency and versatility matter most.

Solvent and eco-solvent printers for deep, saturated colour

Solvent technology has long been valued for its strong, vivid colour output. These printers produce rich blacks, intense reds and blues and excellent density across vinyl and banner materials. Solvent ink penetrates the surface of the media, which gives colour a bold and lasting appearance.

This depth makes solvent printing a popular choice for vehicle graphics, posters, outdoor signage and any work that needs a powerful colour presence. Drying takes a little longer, and some materials are less compatible with the heat used in the process, but the payoff is impressive saturation and durability.

UV printers for crisp, vibrant colour across almost any substrate

UV print technology cures the ink instantly using ultraviolet light, which allows it to sit clearly on the surface of a wide variety of materials. This includes rigid boards such as foamex, acrylic, aluminium composite, and also wood, card, fabrics and corrugated plastics.

UV printing offers exceptional vibrancy and very sharp detail. It supports white ink and varnish layers, which adds creative options and helps colour stand out even further. The ink forms a slightly raised layer when cured, so photographic gradients and very smooth skin tones can sometimes have a more textured look. Despite this, the colour strength and versatility make UV one of the most widely used technologies in professional wide-format print.

A wider colour gamut brings another level of quality.

Many high-performance wide-format printers include additional inks beyond standard CMYK. Colours such as light cyan, light magenta, orange, green, violet, red and white expand the available colour range and improve accuracy in areas where CMYK alone can struggle.

This expanded gamut helps achieve smoother gradients, more realistic skin tones and richer detail in shadows and highlights. Bright oranges, deep purples and complex greens become more achievable. For high-end retail graphics, photography and premium displays, these added colours can transform the final result.

Media choice influences colour as much as the printer.

Even the strongest printer can produce different-looking colours depending on the substrate. Gloss vinyl increases saturation and makes colours appear more striking. Matte vinyl softens the palette for a more refined finish. Canvas absorbs more ink, which creates a natural, artistic feel. UV printing on rigid boards delivers sharp, vivid tones that hold their shape. Backlit films create intense colour depth when illuminated.

Matching the printer to the right substrate is one of the most important steps in achieving the intended outcome.

Why performance varies between suppliers

Two print providers using apparently similar equipment can still deliver very different colour quality. Printhead condition, ink chemistry, calibration, profiling, operator skill and even room temperature can influence the outcome. This is why choosing a reliable machine and maintaining a consistent workflow is essential for repeatable colour.

In summary

Wide-format colour depends on understanding which technology suits which task. Latex provides clean and flexible colour. Solvent creates deep and punchy saturation. UV delivers sharp vibrancy and material flexibility. When extended colour sets and the right substrate are added, the possibilities for achieving powerful and engaging colour become even broader.
