English HP Designjet 130/130nr Printer - Quick Reference Guide Tell Me About Color Calibration Your printer is designed to give prints of an excellent quality. To ensure that color consistency between prints is maintained, you will need to perform a color calibration at various times. Color calibration improves color consistency between prints, and from one printer to another. The printer calibrates color by printing a 'calibration strip' and then scanning the strip with a built-in optical sensor. The printer will then calculate the color correction required, which is then applied to all subsequent prints. Color calibration must be performed whenever a printhead is replaced and for each newly introduced paper type that has not previously been calibrated for the current set of printheads. After you have done the calibration, the calibration data is stored in your printer and is used the next time you print with the same type of paper loaded and the same print quality selected. You must perform the color calibration procedure... • When you install one or more new printheads. • When you use a new paper type for the first time. • Whenever environmental conditions change (for example, temperature or humidity). • Whenever you note a deterioration in the quality of prints. Depending on the amount of use made of the printer, we recommend that you recalibrate it every two weeks or so. To perform a color calibration, refer to "How Do I Perform a Color Calibration?" on page 3. Important: Different color calibrations apply for the default printer driver (RGB) and for the optional HP RIP (CMYK). If you are using a RIP, to perform a color calibration refer to the documentation for your RIP.
