ColorLok Technology is the new standard for better print quality. Paper that’s qualified with the ColorLok logo is able to produce the best possible digital prints.
The ColorLok standard of performance is for plain-paper output with inkjet and laser printers, as well as common copy machines. As such, ColorLok papers will provide consistent and reliable printing regardless of which machine is used within an office environment.
The science behind ColorLok Technology results in more saturated colors, bolder blacks, and faster drying times.
During the paper-making process, a chemical additive is incorporated into the paper to “lock” pigments at the surface. Without this technology, paper acts more like a sponge, absorbing black and color pigments deep into the paper and away from the surface.
Watch: How ColorLok Technology works, John Stoffel, Head Chemist at HP
The ColorLok additive is incorporated into the paper during the paper-making process and produces a chemical interaction with the pigment in the ink. This helps to hold the colorant near the surface of the paper, while the water absorbs deep into the paper fibers. What results is a highly-absorptive and fast-drying product.
Pigment particles are the colorant used in many inkjet inks for home and office printers. Pigments are suspended in a colorless liquid, called the ink vehicle, which rapidly immobilizes pigments at the paper surface.
When ink touches the surface of ordinary paper, pigment particles are absorbed deep into the porous sheet, thereby reducing optical density.
With ColorLok Technology, the ink vehicle penetrates the surface of the paper without transporting the pigment particles into the paper.
ColorLok® papers are available worldwide from a growing number of paper manufacturers and across major brands. Papers that meet the ColorLok quality standard have been rigorously tested in all types of office printing equipment. Look for papers with the ColorLok logo to ensure the highest performance in print quality. Over 4 billion reams of ColorLok paper sold.
ColorLok® is a brand, a technology, a set of performance standards, and a licensing program.
Paper products that carry the ColorLok logo represent a standard for improved home and office printing for both inkjet and laser printers. When the ColorLok logo appears on paper packaging, it assures printer users that the printed output is of the highest quality.
As of March 2015, over 100 paper brands from worldwide sources—including paper mills, merchants, and products branded by office supply retailers—have passed the ColorLok performance specifications and display the ColorLok logo.
