This video shows how to improve an oily finish on prints by adjusting the settings in the
Raster Image Processor, or RIP, software and from the printer's front panel.
The printer shown is the HP Latex 280 -- formerly known as the Designjet L28500.
Prints that are oily appear overly shiny. This can happen due to lack of curing. We
will demonstrate common solutions to improve your prints and reduce oily appearance using
your RIP software or making printing adjustments from the printer's front panel.
Adjusting the media profile in your RIP software can help resolve oily finish issues.
For this demonstration we will use Onyx ProductionHouse X10 software.
Setting the curing temperature too low is a common issue that causes print quality defects
like an oily finish. Navigate to the print queue in the RIP software.
Select your file. Click Edit and then click Printer Settings.
Click and drag the bar under Curing Temp to the right in increments of 5 degrees.
This will depend on the media you are using. Click OK.
Increasing the inter-pass delay allows better curing between consecutive passes and might
improve print quality. Navigate to the print queue in the RIP software.
Select your file. Click Edit and then click Printer Settings.
Click Advanced Options in the Printer Settings window.
Under Inter-pass Delay Offset, use the up arrow to increase the delay time.
Click OK. Click OK, again.
Increasing the number of passes might also help improve print quality because it allows
more time for curing. In the RIP software, navigate to the print
queue. Select the file you wish to print. Select Edit and then select Printer Settings.
In the Printer Settings menu, click the down arrow on the Passes drop-down menu. Select
the desired pass count. Click Yes to accept the change.
Click OK. In this option we will show how to adjust
printing parameters from the printer's front panel to reduce oiliness on your prints.
Printing parameters can be changed from the front panel during printing. However, if you
want to change parameters for future prints, the media profile must be changed from the
RIP. Curing temperatures that are too low might
cause print-quality defects.
First, tap adjustments on the front panel. Then tap Adjust curing temperature.
Tap the up arrow to increase the curing temperature. Tap OK.
Tap OK, again. Increasing the inter-pass delay allows better
curing on consecutive passes. First, tap Adjustments on the lower left of
the front panel. Scroll down to Adjust inter-pass delay offset.
Tap to select. Tap the up arrow to increase the inter-pass
delay. Tap OK.
Tap OK, to save the new setting.
Adjusting the media profile settings can make a noticeable improvement in print quality.
See in this side by side comparison what a marked difference the adjustments have made
to the print. For more details about troubleshooting an
