HP 67 Black Ink: Pigment or Dye, Compatibility, and Whether You Should Switch Ink Types

Question

I'm looking at an ink refill kit and I'm not sure if the black ink included is pigment-based or dye-based. For HP 67 cartridges, does the black use pigment ink while the color inks are dye-based? If this kit uses dye black ink, will it still be compatible with my printer and cartridges? Also, should I be using pigment ink or dye ink in my printer-I'm worried about choosing the wrong type.

Answer

Is the black ink in this kit pigment or dye?

The black ink supplied with this kit is dye-based.

Does HP 67 use pigment black and dye colors?

In many HP cartridge families, it's common for black ink to be pigment and color inks to be dye, but the exact formulation can vary by region, cartridge version, and printer model. That said, the practical question is compatibility-and the good news is:

Will dye black ink be compatible with HP 67 cartridges?

Yes-this dye ink is compatible, even in printers/cartridges that are originally designed around pigment black.

Here's why: most modern consumer inkjet systems can physically run either dye or pigment ink through the same plumbing, but the difference shows up in maintenance behavior (how often the printer cleans) and in clogging risk over time, not usually in immediate "will it print at all" compatibility.

Should you use pigment ink or dye ink in your printer?

Most of the time, you can't truly "make a wrong choice" because many printers will operate with either ink type. The bigger issue is how your printer's firmware handles cleaning:

• Pigment-based printers are typically programmed to clean more frequently because pigment particles are more prone to settling and clogging.

• Dye-based printers often clean less frequently, because dye stays dissolved and tends to flow more easily.

The safest combination (to reduce clogs)

• Using dye ink in a pigment-designed printer is usually safe-and in some ways even safer-because the printer will "over-clean," which lowers the chance of clogging.

• Using pigment ink in a dye-designed printer is riskier, because the printer may not clean often enough to keep pigment particles moving. If you do it anyway, you usually need to do manual cleanings periodically to compensate.

A real-world example: the Epson Artisan 1430 is a dye printer, yet many print shops run pigment ink for T-shirt work-but they also accept the added maintenance.

What's the difference between pigment and dye ink (in plain terms)?

Dye ink (most common for everyday printing)

• Colorant is fully dissolved in the liquid.

• Flows easily and is generally easier to unclog.

• Typically cheaper.

• Produces very smooth gradients and vibrant photos.

Pigment ink (often used when durability matters)

• Colorant is tiny solid particles suspended in liquid.

• Often has better resistance to water smears and UV fade (varies by paper and coating).

• More prone to permanent clogging if it dries out.

Which do I recommend for most users?

In general, I recommend dye ink because:

1. Dye inks are usually more affordable, and

2. Dye clogs are far more recoverable. If pigment clogs hard, it can become permanent.

People often worry: "Dye ink isn't waterproof or UV resistant." For typical home or office use, that concern is usually overblown. Most prints aren't left in direct sun for long periods, and most spills (like coffee) don't instantly ruin dye prints unless they remain wet for a long time or the paper is extremely absorbent. Unless you're producing outdoor signage or prints that will be exposed to rain, dye is usually the best all-around choice.

Is it safe to switch ink types? Can you mix pigment and dye ink?

This is where people get into trouble, so here's the practical truth:

Switching dye → dye

No issue.

Switching pigment → pigment / pigment ↔ dye

This is where caution matters. Dye and pigment inks typically use different base solutions. Pigment needs a chemical "matrix" to keep particles suspended. If that balance is disrupted, pigment particles can clump together over time and create clogs.

Best practice when switching types:

1. Use up as much of the old ink as possible.

2. After switching, print enough pages to flush out the old ink from the lines and printhead.

Can small mixing happen without disaster?

Sometimes, yes-small amounts of mixing aren't always lethal. For example, some OEM formulations and certain third-party inks use blended approaches. It's all about ratios and base chemistry.

However, here's the bigger warning:
Switching between third-party inks is always a gamble. Even if you stay dye-to-dye, different manufacturers may use different bases. Once you find an ink that behaves well in your printer, the safest move is to stick with it.

How to reduce switching risk even further

If you understand the clogging mechanism (base incompatibility), you can reduce risk by using a compatible "base" solution to dilute and flush before the switch. We carry:

• Clear dye base: (https://bchtechnologies.com/universal-dye-ink-bas...)

• Clear pigment base: (https://bchtechnologies.com/universal-pigment-ink...)

For many users, this is overkill-most people won't need it-but it's an option if you're doing frequent changes or rescuing a finicky system.

Practical rule-of-thumb summary

• You can use dye ink in a pigment printer (often safer because the printer cleans more).

• Using pigment ink in a dye printer is not ideal unless you do manual cleanings regularly.

• Pigment ink compatibility can be more model-sensitive because pigment bases vary more between brands.

• When switching ink types, use up old ink first, then flush by printing after switching.

• As a general guideline, many users can mix up to about 20% during a transition without immediate clogging risk-but the safest approach is always to flush as thoroughly as possible and avoid long-term mixed use.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems, so we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We do offer an in-person evaluation and repair service through our local diagnostic facility: BCH Printer Repair Service (https://bchtechnologies.com/printer-repair-service). Because demand is high, we run on a first-come, first-served basis, and it can take a few weeks before we're able to accept a printer for drop-off. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed. We also recognize our rates aren't the most economical, so we strongly recommend self-help through online research first. You can start by checking YouTube or visiting our channel homepage: BCH Technologies YouTube Channel (https://youtube.com/@bchtechnologies). To find relevant videos quickly, use the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of questions every day asking if there's a video for a specific topic, and after making videos for over nine years, it's tough to remember every single one-YouTube's search is the fastest way, and it may also recommend useful videos from other channels that can help too.

Thanks again for reaching out and for supporting BCH Technologies. I appreciate the opportunity to help you make the right ink choice with confidence.
