HP 45 (51645A) Ink Cartridge: Denser, water-resistant black for professional prints

Rich black that resists fading and water for reliable documents.

Product Overview:

You just want prints that look right the first time. This cartridge answers that with pigment-based black ink tuned for denser, water-resistant output. It drops into older HP Deskjet, Officejet, Designjet and Color Copier models so you don't have to replace equipment. If you run a small office, home studio or classroom, you'll value prints that resist smudges and fading. Use it for invoices, handouts or proofs that need to last. It behaves nicely on HP specialty papers, transparencies and plain paper alike. Picture a stack of documents that still reads clearly after a coffee spill or a summer on the shelf.

Key Features:

• Pigment-based Ink: Built with pigment-based ink, it gives rich blacks and resists water and fading so your text stays legible.
• Print Yield: Approximately nine hundred thirty pages from a single cartridge reduces interruptions and keeps everyday printing economical.
• Compatibility: Fits a long list of legacy HP Deskjet, Officejet, Designjet and Color Copier models so you don't replace printers.
• Paper Handling: Works cleanly on plain paper, transparencies and HP specialty stocks for dependable results across jobs.
• Lightfastness: Lightfastness keeps documents readable over time, which matters for archival notes and client proofs you want to keep.
