HP 776 Gray Ink 1XB05A 1 L DesignJet Ink Cartridge

Name: HP 776 1-liter Gray Ink Cartridge (1XB05A)
SKU: 1XB05A
Availability: InStock

HP 776 gray ink 1XB05A is a genuine HP ink cartridge built for consistent, professional results on compatible HP DesignJet production printers. Gray ink plays an important role in smooth tonal transitions, neutral grayscale output, and detail control in shadows and midtones. If grayscale areas begin to look grainy, banded, or slightly color shifted, replacing your HP 776 gray cartridge can help restore clean, predictable output for demanding photo and graphics work.

This cartridge is used with the HP DesignJet Z9+ Pro 64-in series and the 1 L capacity is designed for higher volume environments that want fewer cartridge changes during production. For print teams running posters, display graphics, and photo output, fewer interruptions can mean smoother workflows and less downtime. Genuine HP ink supports controlled ink delivery and consistent coverage, helping reduce reprints caused by uneven tone, banding, or drift between runs.

Gray ink helps stabilize neutral areas and supports smoother blends where color transitions need to remain natural. This is especially useful for black and white prints, image heavy posters, and graphics that include subtle shading. When paired with consistent media and stable print settings, HP 776 gray helps keep your results predictable for repeat jobs, reprints, and multi copy orders where appearance and consistency matter.
