Designed to achieve the full print-quality potential of the HP T300 Color Inkjet Web PressThe HP T300 Color Inkjet Web Press is a solution designed to support the analog-to-digital transformation of commercial and industrial printing applications. Printing up to 30 inches (762 mm) wide at 400 feet (122 m) per minute, this press breaks cost and performance barriers and enables a range of printing possibilities including book publishing, direct mail, transactional printing1 and newspapers.

Papers with ColorPRO Technology support the full print-quality potential of the HP T300 Color Inkjet Web Press. Designed for HP pigment inks, these papers provide noticeably enhanced print quality compared to standard uncoated offset papers.

The ColorPRO differenceColorPRO papers perform to a strict set of specifications that define color excellence.

The performance criteria includes:• High color gamut• Line edge acuity • Limited color-to-color bleed

Specifications and methodology are detailed during the ColorPRO qualification process administered by the independent third-party test facility.

The difference is striking:• Offset-comparable black provide remarkable text and solid area fills• Better-than-SWOP color gamut2 creates radiant results• Crisp text-over-color placement enables limitless full-color options

With ColorPRO Technology, customers experience visibly enhanced print quality at maximum throughput.

ColorPRO TechnologyIn the case of papers compatible with the HP T300 Color Inkjet Web Press, ColorPRO Technology is based on a class of paper additives that visibly enhance the print quality of inkjet printing compared to standard uncoated offset papers. The additives help fix the colorants in many inkjet inks near the surface of the paper delivering professional quality and striking results.

ColorPRO Technology employs an innovative new approach in which a specific chemical interaction between the additive and the pigment in the ink helps fix the pigment at the paper surface while the rest of the ink penetrates deep into the paper (see Figure 1). This specific interaction between the ColorPRO Technology additive and the ink colorant enables a paper design for the HP T300 Color Inkjet Web Press that offers a unique combination of print quality and rapid ink absorption. The result is professional quality and striking results at maximum throughput.

How does the technology work?ColorPRO Technology additives control pigment ink absorption into the uncoated paper to achieve:

• Controlled ink penetration• Controlled dot spread• Improved print density and color gamut volume• Crisp text-over-color placement• Sharper lines, improved line quality

HP patented technology is introduced into the paper-making process, delivering visibly enhanced print quality when used with HP pigment inks.

Print quality enhancements are visible in each of the areas illustrated in Figures 2 and 3 for performance on papers compatible with the HP T300 Color Inkjet Web Press.

The additives achieve noticeable improvements, accomplished with precise control over how the ink behaves at the surface and as it penetrates into the paper. The additives essentially immobilize the pigment in the ink at the surface of the paper, keeping more colorant at the surface and achieving higher black optical density, which appears as higher contrast black and more striking colors.

Dot placement is precisely controlled, reducing black line raggedness and appearing as sharper lines. In the more challenging case of multiple inks printed as text over color, immobilizing the pigment at the paper surface reduces color-to-color bleed which appears as sharp, clean text-over-color placement.

And there are additional benefits—ColorPRO Technology is designed to provide enhanced print quality on lighter-weight papers that can, in turn, enable lower overall costs of printing, transportation, and distribution.
