Why choose the OKI Pro9541 and Pro9542 for your print business


The OKI Pro9541 and Pro9542 have revolutionised the professional print sector by bringing five-colour, digital LED printing within reach of commercial printers and in-house design studios. Unlike conventional CMYK printers, these models offer you the ability to print full colour plus extra spot colours—including brilliant white and clear gloss—in a single pass. This opens up entirely new revenue streams, allowing you to produce premium packaging, concept proofs, window graphics, and luxury stationery on demand.

OKI Pro9541: CMYK + White or Clear Gloss


The [OKI Pro9541](/product/oki-pro-9541-a3-colour-printer-46291801/) provides the ultimate flexibility for creative studios. It is the world's first digital LED professional printer to offer CMYK plus an additional fifth spot colour in either white or clear gloss. The clear gloss acts as a spot UV-style finish, adding stunning impact to marketing collateral and business cards, while the white toner ensures bright, solid text and graphics over coloured media.

OKI Pro9542: CMYK + High-Density White under-printing


For businesses focused on printing on dark, coloured, or transparent media, the [OKI Pro9542](/product/oki-pro9542dn-a3-colour-led-laser-printer-45530622/) is the preferred choice. It lays down a high-density, solid white background underneath the CMYK artwork in a single pass. This ensures that colours remain vivid and accurate, even when printing on black card or clear vinyl, making it perfect for bespoke packaging, labels, and creative signage.

Unparalleled Media Flexibility


Both the OKI Pro9541 and Pro9542 boast incredible media handling capabilities. You can print on an extensive range of substrates, including heavyweight card up to 360gsm, magnetic media, transparent films, and gloss paper. They also support varied formats from standard A3 to SRA3 and banners up to 1.3 metres in length, ensuring you can say yes to almost any short-run print request.
