Q2344A – HP 1918 Dye-Based Black Print Cartridge

HP designed the Q2344A, 1918 Dye-based Black print cartridge specifically to support intermittent industrial printing on a wide variety of substrates: coated and uncoated papers, labels, and specialty media.
This dye-based ink optimally penetrates the surface of the substrate, producing sharp, crisp output without smearing or transfer—ideal for the packaging industry and other markets that need consistently robust results. On coated substrates, such as photo papers, this dye-based ink enhances the glossiness of the medium.
Higher decap times reduce nozzle dropouts in production environments with intermittent printing requirements.
Unlike some pigmented inks, the dye-based ink in this print cartridge is water-based, not solvent-based, so production facilities do not need additional ventilation, special chemical cleaners, or qualified service technicians who can handle solvents.
Benefits
The Q2344A, 1918 Dye-based Black print cartridge is:

• Reliable. Higher decap times minimize servicing requirements between print jobs and ensure consistent high-quality output.
• Versatile. Prints on a wide variety of substrates, so customers have a greater range of media choices.
• Effective. 1918 Dye-based Black ink can be used on top of several types of offset inks, in knockout areas on porous packaging materials, and on ink-receptive coatings.
• Efficient. Drop-on-demand technology makes maximum use of ink supplied in the print cartridge.

What are the key advantages of this print cartridge?

• Continuity of printing. Higher decap times ensure an immediate startup every time—virtually eliminating the need to service the printhead between print jobs.
• Excellent print quality. 1918 Dye-based Black ink produces sharp, crisp, durable output without smearing or transfer.
