The L25500 printers are primarily intended for producing signage for both internal and outdoor use. Inks  are latex based  and outperform water  and eco-solvent types.

• Produce outdoor signage with durability comparable to eco-solvent inks.

• Achieve high-quality results for indoor signage applications, from exhibition graphics to interior decoration.

• Print on a wide range of media, including coated media or polyester fabric and low-cost papers without treatments.

• Experience easy, unattended printing with HP Thermal Inkjet printheads and automatic maintenance. User replaceable printheads avoid the delay and expense of a service call.

• Automatically achieve high image quality and consistency with the HP Optical Media Advance Sensor (OMAS) and embedded spectrophotometer.

1) User-replaceable printheads Less intervention for changing printheads avoids delays and improves your turnaround time. HP printing systems using Original HP printheads and water-based HP Latex Inks do not require daily manual maintenance of printheads as the printer employs fully-automatic printhead testing and maintenance systems. Individual printheads are user replaceable, eliminating the down-time and expense of a service call. Together, HP printheads and HP Latex Inks enable low-maintenance, productive printing.

2) Included take-up reel Do you have more to print than you can keep up with? Busy professionals can make the most of their time and improve productivity by printing continuous, unattended runs—even overnight—and on long media rolls with the media take-up reel that comes standard on both 42-inch and 60-inch models of this printer.

3) Completely dry right out of the printer Improve your turnaround time with prints that are dry and ready immediately. HP Latex Inks are completely dried inside the printer to form a durable film on the print medium. Once they’re off the printer, they’re ready to laminate, use, finish, and prepare for shipping or display.

4) Optical Media Advance Sensor and Optical Drop Detector Automatically achieve high image quality and consistency with the HP Optical Media Advance Sensor (OMAS) and the Optical Drop Detector (ODD). OMAS controls the media as it advances through the printer, which helps minimize banding at high speeds. The drop ejection performance of every printhead nozzle is periodically and automatically tested with the ODD, providing prints free of defects or errors that can result in ink and media waste.

5) HP Double Swath technology Pairs of staggered printheads in the carriage double the print swath of the HP Designjet L25500 Printer series resulting in twice the performance of earlier Designjet models. The print swaths overlap each other and the nozzles printing in the same scan line (top and bottom printheads) are used together to eliminate swath-to-swath banding.

6) Embedded Web server Control print settings and monitor your printer’s use of ink and media via the embedded Web server—which is also accessible through your preferred RIP. This information will help you better manage print jobs and prevent unnecessary ink and media waste.

Image Formation Process Unlike other water-based inks, HP Latex Inks are cured in the printer with heat and forced air. The HP Designjet L25500 Printer includes independent Print Zone and Curing Zone heating systems to cure HP Latex Inks. The temperatures in each zone depend on the print mode and media being used. Figure 1 shows a schematic drawing (not to scale) of a liquid film of HP Latex Ink in the Print Zone on the surface of nonabsorbent media, such as uncoated vinyl. In Figure 2, radiant heaters and forced air in the Print Zone and Curing Zone evaporate the ink vehicle and cure the latex film. In Figure 3, a continuous latex film encapsulating the pigments has formed on the vinyl surface as the print leaves the Curing Zone.
