The principle behind Color Reproduction is that the original and the final image relate to each other according to the desired reproduction intent. It is also important to underline that the process includes image enhancement. This feature is included so that when the original is noisy, badly contrasted or imperfect, the resulting output can be enhanced (smoother, better contrasted, with enhanced edges and lines). In this case, the process is mainly driven by image enhancement rather than color reproduction fidelity. The following sections describe in more details each component of the HP Color Reproduction system. 3.1.1 Original The original is where the image to be reproduced resides. In relation to color and image enhancement, originals can be classified as follows: • According to the way the image was created: o Inkjet originals ƒ Thermal Inkjet ƒ Piezoelectric Inkjet ƒ Continuous Inkjet o Non Inkjet originals ƒ Press/Offset ƒ Silver Halide (traditional photography) ƒ Electro photography: - Dry ink (toner): laser printers - Liquid ink: Digital Press ƒ Others • According to the contents of the image: o Pictorial images o Maps and graphic images with solid areas o CAD and drawings with solid lines o Text Documents • According to the color content: o Color images o Monochromatic images: ƒ Black and white ƒ Sepia ƒ Blueprint Color Reproduction for the HP Large Format Color Copiers family: cc800ps, 815mfp, 5500mfp and 4200 scanner 27/27
