Extraordinary results that transcend expectations.

Now you can demonstrate your creativity or broaden your printed offerings by producing materials on an incredible range of media in 4-color plus solid White or Clear gloss toners. These processes—which used to require expensive printing equipment and outside resources—are available in-house and on demand with the C941e, a unique 5-station multimedia production platform device from OKI®.

The C941e gives users the ability to create extraordinary mock-ups, stationery, invitations, brochures, packaging prototypes, point-of-sale material, watermarks, window graphics, labels, etc., in breathtaking HD Color that now includes White or Clear spot color!

Apply White toner first or last

Use white text and graphics on dark-colored media. Make 4-color images on dark media stand out by laying down White toner first and printing CMYK on top—the same technique used for producing vibrant 4-color images on translucent media or transparency film.

Two minutes from White to Clear.

That’s all it takes to switch the 5th station of the C941e from White toner to Clear Gloss toner—and back again. Each color kit comes with all you need to get spectacular effects on opaque, translucent or transparent media with no fuss. And the front-accessible compartment makes exchanging or replacing consumables even easier.
