Color calibration is based on the color measurement of printed color patches, using the embedded spectrophotometer. Some characteristics of substrates, such as surface roughness or transparency, may make reflective color measurement of some substrate types very inaccurate. Color calibration of these substrates may fail or produce unacceptable printing results. TIP: If color calibration fails at the first attempt, it is worth trying again. To delete the reference for a given substrate, so that you can create a new reference for that substrate, you must reset the color calibration. In the Internal Print Server, click Substrate > Color calibration > Reset. Color consistency between different HP Stitch printers It is possible to cross-calibrate color between two or more printers for particular substrates. After crosscalibrating a given substrate, you can expect to get very similar prints from either printer when using the same substrate. 1. Choose printer A to be the reference printer, and use it to perform color calibration on the substrate in question. See Color calibration on page 93. 2. Export the calibrated substrate preset. See Substrate presets on page 48. 3. Import the substrate preset of step 2 into printer B. See Substrate presets on page 48. 4. Color-calibrate the preset with printer B. 5. Colors printed with printer A and printer B, on that substrate, should now be very similar. 6. To add more printers (C, D, and so on), proceed as you did with printer B. Color emulation of other printer models An HP Stitch S500 64in printer can be set up to emulate colors printed by an HP Stitch S1000 126in printer. The emulation process is done by importing a source (S1000) substrate preset into the destination (S500) printer, that was created, color-calibrated, and ICC-profiled in the source printer. The original or source substrate preset contains a number of paper modes and a color-calibration reference. A new substrate preset is then added to the destination substrate library that keeps the same name as the source substrate preset. This destination preset contains the paper modes that are the closest equivalent to the source ones in terms of ink density and number of passes. Color emulation between source and destination, for the given substrate material, can then be achieved by performing color calibration of the destination substrate preset. If the source substrate preset has not been color-calibrated, it can still be imported into the destination printer. A translated set of paper modes will still be created, but color emulation of the source printer cannot be optimized. Color emulation between printers of different models is based on the same principle as color consistency between printers of the same model; that is, exporting a source color-calibrated substrate preset and then importing it and color-calibrating it in a destination printer. When the printer model is the same, most printing settings and color resources are implicitly matched, such as printing engine, mechanical settings, paper mode and associated ICC profiles. However, when emulating the colors of a different printer model, you are advised to follow these recommendations: ● Use the same substrate type in both source and destination printer (this is also recommended between printers of the same model). ● Choose a paper mode in the destination substrate preset that is as close as possible to the active paper mode in the source substrate preset. ● Use the same workflow in your RIP software to print to the source and destination printers.
