OKI Pro 9542 CMYK + White A3 Colour Printer
The OKI Pro 9542 is a professional A3 colour printer with CMYK plus white toner, designed for creative, packaging and specialist print applications. By combining high quality colour with opaque white, it allows you to produce vibrant prints on coloured, dark and transparent media that are not possible with standard CMYK printers.
Built for short run production, the OKI Pro 9542 is ideal for businesses that want greater control over their print output without relying on external suppliers. It is widely used for packaging mock ups, labels, envelopes, signage and promotional materials, delivering consistent commercial grade results with minimal setup time.
The inclusion of white toner opens up new creative possibilities. White can be printed as an underlay to increase colour vibrancy, as a spot colour for premium effects, or as an overlay for added definition. This makes the Pro 9542 particularly suited to branding, packaging and design environments where impact and flexibility matter.
Using OKI’s ProQ LED technology, the printer delivers smooth gradients, sharp detail and accurate colour reproduction. Its A3 print capability supports larger formats and complex layouts, while its ability to handle a wide range of media makes it suitable for specialist stocks, labels, synthetics and envelopes.
