HP ColorSphere toner produces a finer range of colors for subtle transitions, realistic images[1]

HP ColorSphere toner produces a finer range of colors. To ensure extreme precision in the printing process, HP's color toner uses advanced toner formulation technology. Each toner particle that's produced conforms to an extremely consistent size and shape, allowing the particles to be placed on the page with the precision that's needed to produce a wide range of colors with even the most subtle differences of shade. With this precision, you get high-impact photo-quality business printing.

The HP printing system is tuned to HP's ColorSphere toner, ensuring brilliant color and consistency.

For consistency over the cartridge's life, HP Smart technology[2] in HP supplies and the printer relies on the unique properties of HP ColorSphere toner. As the system triggers adjustments to the electrophotographic voltages inside the toner cartridge, a precise mix of patented additives—fine-tuned for quality results under diverse environmental conditions—ensures consistency. HP supplies and the printer work together to ensure the quality of each print, saving time and providing real value.

Proprietary technology in HP Color Laser Glossy Photo Paper and HP ColorSphere toner—better together

HP optimizes the interaction between each component of the HP Color LaserJet printing system for the highest-quality, most consistent results. HP's proprietary, five-layer technology in HP Color Laser Glossy Photo Paper locks the color into the coating to achieve higher gloss. The result is brighter, more uniform color.
