Z9+ example chart 2. The chart is allowed to dry for a period of time that depends on the paper type, so that the colors have time to stabilize. 3. The chart is scanned and measured. 4. From the measurements, the printer calculates the necessary correction factors to apply for consistent color printing on that paper type. It also calculates the maximum amount of each ink that can be applied to the paper. Color profiling Color calibration provides consistent colors, but consistent colors are not necessarily accurate. For instance, if your printer prints all colors as black, its colors may be consistent but they are not accurate. In order to print accurate colors, it is necessary to convert the color values in your files to the color values that will produce the correct colors from your printer, your inks, and your paper. An ICC color profile is a description of a printer, ink, and paper combination that contains all the information needed for these color conversions. Create your own profile (Z9+ only) You can create a color profile easily using the HP Utility. The process takes about 15-20 minutes and consists of the following steps: 1. Load paper into the printer: see Load a roll into the printer on page 29 or Load a single sheet on page 32. You will find the paper name in the paper or custom paper category in the front panel and the HP Utility. If you cannot find the paper name, you can create your own paper preset: see To create your own paper preset on page 36. IMPORTANT: When loading the paper, make sure to select the correct paper type. Loading the paper with an incorrect paper type specified could cause errors in the profile. NOTE: The paper must be calibrated before profiling. 2. Go to the HP Utility. ● Under Windows: Click Profile paper. ● Under macOS: click Paper management, then at the bottom of the window, then Profile paper. 3. The printer asks you about the process to be used. Print target and ICC profile is the standard option and suitable for most cases. If you would like to use a longer drying time, you can ask the HP Utility to create the chart without going on to create a profile (Windows: Print target only. Create ICC profile later; macOS: Print ICC profiling chart). Then, later, when the chart is completely dry, you can use the HP Utility's Color Center to create a profile using the chart you have already created (Windows: Create ICC profile from a target that has already been 90 Chapter 8 Color management ENWW
