HP Designjet H35000, H45000 and Legacy UV Printers - Tips and Tricks for Glass and Acrylic

Once the calibration has been performed, take note of the Media Feed Number (MFN) displayed on the printer’s

control panel and the end of the calibration. This MFN can be entered again in the future when printing on the same

material, eliminating the need to reprint a calibration pattern. Note that the MFN is speciﬁ c with regard to sheet di-

mensions and to print mode. A separate calibration will need to be performed to obtain valid MFNs for each desired

print mode.

Media Preparation

On the Designjet H35000/H45000 Printer series (ColorSpan 5400UV Series) and UVR-UVX series of printers, the

media is pulled through the printer by the action of gritted rollers biting into the bottom surface of the media. This

method could leave undesirable marks on the media, so some means of protecting the bottom surface is recommend-

ed. Any release liner already present on the media should be left in place, or transfer tape can be applied to the

bottom surface for protection. If no such protection is available, be sure to load the media from the input side (back)

of the printer, to minimize any travel over the stationary grit rollers.

Cleanliness

For best results the media must be thoroughly cleaned before printing. Wiping down the media surface with alcohol

will remove any particles and also reduces any static electricity buildup on the media that could affect print quality.

Server Preparation

If using an HP print server, we recommend the Backlit color proﬁ le. This delivers an ink saturation that produces good

results for most applications involving glass, clear acrylic, or similar media.

If using a third-party print server, similar settings that use a generally higher ink limit are suggested. Some trial-and-

error and experimentation may be required to ﬁ nd the best color settings for your speciﬁ c media and application.
