Ink for HP T790: what matters most in everyday printing

When you choose ink cartridges for HP T790, you’re investing not only in color, but also in sharp lines, predictable drying time and stable coverage on a variety of media. In technical environments, even minor color shifts or broken lines can cause costly misunderstandings—this is why the right ink for HP DesignJet T790 Series should deliver consistent results from the first to the last print.

Inks and printheads dedicated to the T790 support common applications such as:

• CAD drawings and construction documentation (thin lines, legibility of small text),
• maps and GIS visualizations (repeatable color and smooth fills),
• posters and presentations (deep blacks and clean gradients),
• office and project documentation printed on large-format media.

Equally important are printheads—because even the best cartridge won’t help if the nozzles are worn or clogged. That’s why our offer includes not only ink for CR649A but also dedicated HP 72 printheads.

How to choose the right ink for HP DesignJet T790 - CR649A

When selecting ink for HP DesignJet T790 - CR649A, we recommend checking three things:

• Compatibility code – look for HP 72 cartridges and dedicated printheads; product symbols like C9403A, C9371A or C9383A help confirm the exact variant,
• Color and purpose – Matte Black is often chosen for technical documents, while Photo Black is useful for presentations and images,
• Capacity – XL versions are a great choice when you print a lot and want fewer replacements.

Many users of the HP Designjet T790 Series ask us about typical issues such as uneven lines, missing color, banding, or sudden quality drops. In most cases, the cause is one of the following:

• an ink level running too low in a frequently used color,
• a clogged or worn printhead (replacement can immediately restore precision),
• printing irregularly—long breaks can dry ink in nozzles, so periodic test prints help.

If you’re not sure whether you need a cartridge or a printhead, tell us what you see on the print (e.g., which color is missing, whether the issue repeats in the same place). We’ll help you choose the fastest and most cost-effective fix.

Original OEM vs compatible: what to expect

In this subpage we focus on Original OEM products designed for HP T790 and CR649A. Original cartridges and printheads are built to meet strict factory specifications, which is important in environments where repeatability is critical.

At the same time, many customers also consider compatible solutions for everyday printing. If you’re comparing options, keep one thing in mind: compatible cartridges available at DrTusz.pl are selected to be just as good in practice—offering strong print quality and dependable performance—while helping optimize printing costs. If you’d like, we can advise when OEM is the best choice and when a high-quality compatible alternative is the smarter option.
