HP Color LaserJet toner
cartridge technology
Your customers are actively looking for solutions that will make in-house colour
printing commercially viable and the development of a number of new HP Color
LaserJet series is doing just that. Building on this momentum, and playing a key
role in driving customer migration from mono to colour printing, are our HP Color
LaserJet print cartridges.
Like mono HP LaserJet print cartridges, they are purpose-designed to interact with
HP printers and media to deliver high quality results with maximum reliability, and
they feature the latest HP Smart Print technologies to provide accurate supplies
monitoring and consistency of print quality.
However, the technology behind colour printing is clearly more complex: how do
four basic toner colours create millions of other colours? In the case of HP Color
LaserJet printers, a technology called ImageREt precisely places tiny dots of toner
in adjacent or overlapping positions while varying the size of nearby colour dots.
This combination of four colours – in extremely tiny patterns and sizes – represents
consistent colour images to the human eye.
Individual toner particles must be uniform in size to ensure colour accuracy is true
to the eye. The particles must also be placed very accurately on the page. And
since most printed areas are a combination of colours, the correct amount and
placement of toner is critical to accurate colour reproduction.
Ultraprecise spherical colour toners
Most toner is mechanically grown, which produces an irregular toner particle.
Our chemically grown colour toners are spherical in shape, with highly consistent
colour. The particles are very small in size, allowing for very precise placement to
create colours that are more accurate and consistent.
