Aster Graphics Inc 728 4-Pack Ink Cartridge Black/Cyan/Magenta/Yellow 300ml BK 130ml CMY

Four-colour high-yield set for DesignJet plotters

This 4-pack of aftermarket ink cartridges replaces HP 728 originals for the DesignJet T830 MFP and T730 large-format plotters. It supplies black, cyan, magenta and yellow in a single box so a print shop or CAD department can restock all colours at once. The cartridges are new and carry a one-year warranty with a two-year shelf life.

Capacity split gives 300 ml black

The black cartridge holds 300 ml, enough for long monochrome runs such as line drawings or text-heavy plans. Each colour cartridge holds 130 ml, which covers regular coloured markup and presentation sheets but will need replacement sooner on full-colour posters or heavy photo areas. Users printing mostly black-line work will see the colour tanks outlast the black, while graphics-heavy output reverses that balance.

Direct replacement for HP 728 series in T830 MFP

These cartridges are built to the HP 728 form factor and chip specification so they install without adaptation in the listed DesignJet models. They do not fit other DesignJet series or HP office printers that use different cartridge numbers. Buyers with mixed printer fleets must verify the exact model before ordering.
