6. If you see horizontal banding, check the substrate advance pattern in the test sample (the fine horizontal lines on the right-hand side). Handle the substrate ● If the pattern shows regular banding, adjust the substrate advance factor later while printing. ● If the pattern shows irregular banding, proceed to the next step. 7. If you see irregular horizontal banding, try these adjustments in this order: a. Decrease the Vacuum setting in steps of 5 mmH20, unless you have already increased it in a previous step. b. Adjust substrate tension according to the following recommendations: ● The input tension should be the output tension + 15 N/m. ● First increase tensions by 20 N/m. If results are unsatisfactory, decrease tensions in steps of 10 N/m. c. Increase the number of passes. 8. If colors are misaligned, try realigning the printheads manually. See the Maintenance and troubleshooting guide. When you have adjusted the settings for one print mode, you can proceed to other print modes. However, it's not necessary to deal with them all at once: you can edit the substrate preset at any time by selecting Substrate > Modify in the HP Internal Print Server. TIP: Note the settings that you used with the first print mode. You can probably use the same settings for other modes. Adjust the printing workflow for optimum color performance 1. Check your substrate's color calibration status and calibrate it if recommended, by selecting Substrate > Color calibration in the HP Internal Print Server. See the 'Printer calibration' chapter in the Maintenance and troubleshooting guide for more information. 2. Create ICC profiles for your substrate; see your RIP documentation for instructions. Normally, the procedure includes setting the total ink limit as well as creating the profiles. When setting the total ink limit in the RIP, bear in mind the basic problems to be avoided: ink bleeding and coalescence, and damp prints caused by incomplete curing. Export your new preset and profiles Your substrate has been fully characterized from both the printer and the RIP points of view: a substrate preset is present in the printer, and one or more ICC profiles are present in the computer hosting your RIP. To export the ICC profiles, see your RIP documentation. To export your substrate preset, go to the HP Internal Print Server and follow these steps: 1. Select Substrate preset management. 2. Select the Export tab. A file with the extension oms will be saved, which can be imported by another printer.

Export your new preset and profiles
Your substrate has been fully characterized from both the printer and the RIP points of view: a substrate
preset is present in the printer, and one or more ICC profiles are present in the computer hosting your
RIP. To export the ICC profiles, see your RIP documentation. To export your substrate preset, go to the
HP Internal Print Server and follow these steps:
1.
Select
Substrate preset management
.
2.
Select the
Export
tab. A file with the extension
oms
will be saved, which can be imported by another
printer.
