PhotoREt III Photo Resolution Enhancement technology enables business inkjet printers to produce photo- quality color images. PhotoREt III’s Color Layering technology combines small ink-drop- volume ink cartridges, vibrant, fade-resistant color inks, new halftoning algorithms, and specially developed HP Premium Plus Photo paper to deliver outstanding image quality and performance. The increased capacity of HP business inkjet 2230/2280 printers place up to 20 drops of ink in a single dot that creates finer color control and produces five times the number of colors produced by PhotoREt II printers.
PhotoREt III enables faster color print speeds without sacrificing speed for print qualit UnderPrinting UnderPrinting prints a small amount of color ink (cyan or magenta) underneath the black ink. The pigment-based black ink penetrates the media at a slower rate than the dye-based color inks. UnderPrinting increases the penetration rate of the black ink. The new printhead arrangement of the HP business inkjet 2230/2280 allows color ink to be printed on the page before the black ink in both carriage directions. Since black can now be printed in both directions with UnderPrinting, faster throughput can be achieved.
UnderPrinting also provides significantly improved smudgefastness, dry time, K Optical Density, and print quality. 1-30 hp restricted tour the product
