Why TIJ Cartridge Prices Vary: Eight Questions Before You Order

You have two quotes. Both say “42 ml black TIJ cartridge”. One is half the price of the other, and nothing on either sheet explains the gap.

That gap is real, and it is not simply quality. One cartridge may carry a newly built printhead. The other may be a used unit filled again. One ink may be fine on corrugated board and useless on a coated pouch. One supplier can trace a batch and answer a defect claim. The other offers a price and a phone number.

If you print batch numbers, expiry dates or scan codes, a short fill or a missing stroke does not stay a supplier problem. It stops your line.

So do not argue about expensive versus cheap. Ask eight questions instead, and test the answers on the job you actually run.

First, establish what you are buying

Like-for-like pricing requires like-for-like parts.

In most TIJ systems the printhead is part of the cartridge. A new cartridge brings a new ejecting surface. A refilled cartridge keeps the head it has already fired — for however many million drops before it reached you.

Think of a refurbished laptop. A new battery may make it useful again. It does not make the other components new. “Fresh ink” tells you nothing about the remaining condition of the nozzles, the contacts, the seals or the absorbent structure. After several fills, ask how the seller tracks prior use and how cartridges are screened before sale. If they cannot tell you, treat the unknown history as a cost.

Ask these four together:

• Which exact machine and cartridge model are supported?
• Are the housing and the printhead newly manufactured?
• Is this a first fill, or a refill of a used unit?
• What batch identification and fill date come with the cartridge?

The answers belong on the quotation or an attached specification, not in a phone conversation. Two cartridges can look identical and carry different electronics or behave differently with the same ink. Our cartridge range lists the formats we supply, and the difference between a genuine and a rebuilt cartridge is worth reading before you accept a refill quote.

A distributor printing serial numbers on cartons of electronics has the same exposure as one receiving a defective unit: the wrong variant costs as much as a broken one. Even when it fits mechanically, the machine may demand a specific cartridge identification or operating parameter. Take a small trial quantity before ordering cases, and confirm the machine configuration with both parties.

Then describe the job, not a generic ink

A price without a substrate is an incomplete price.

TIJ work runs from porous cardboard to non-porous film and specialty surfaces. Water-based and solvent inks are good at different things, and some requirements need a formulated specialty ink. The difference shows up within seconds on the line: a water-based ink sinks into corrugated almost immediately, while a fast-dry solvent on PE, PP or PET is usually touch-dry in 1–5 s.

Adhesive tape is the easy comparison. Tape that grips clean cardboard may release from an oily or textured tub. Likewise, a cartridge that prints a beautiful sample on paper can smear on the finished pouch — especially if the pouch is coated, treated, or reaches a guide roller a few centimetres downstream.

Ask the next three:

• What ink formulation is inside, and which real substrate has it been tested on?
• What are the documented storage and handling conditions?
• What evidence backs any adhesion, rub-resistance or regulated-use claim for this specific ink?

If you print a QR code, define readability with the scanner or inspection method used at your plant. If the job is a short date on an outer case, do not pay for capability you will never use.

Quantity claims need a context too. “42 ml” says nothing about how many acceptable codes your artwork yields. A sparse date and a dense dark logo cover very different area; so do a small text line and a large data matrix. Ask for a print of your actual file, and for the speed, settings, material and acceptance standard behind any promised yield. Without those, prints-per-cartridge is a marketing estimate, not a commitment.

A beverage line printing a date just before the bottles hit the guide rails is the classic case. A sample left on a desk looks perfect; the label on the line smears within seconds. So test the actual label, at line speed, at the point where real handling begins. That turns cartridge selection into a process decision instead of a contest between photographs.

The eighth question decides whether you can repeat the purchase

What happens if the cartridge fails the production test you agreed?

A supplier who knows the product can answer: trial quantities, inspection criteria, batch tracing, and a sensible response to defective units. You, in turn, supply the machine, the material, the artwork, the speed, the run time and your acceptance rule. Both sides then have the conditions to separate a consumable fault from an equipment setup problem.

Run the candidates on the same machine, with matching print settings, material batch and line speed. Capture a starting sample, samples after extended running, and the first codes after a realistic pause. Record missing strokes, failed scans, wiping, cartridge changes, rejected packs and stopped minutes. Then calculate total cost divided by accepted codes. A low unit price that eats operator attention loses its advantage. A premium cartridge that fails on your surface does not deserve its premium either.

Resist one-factor explanations. A nozzle gap that opens as the pack passes, poor trigger timing, a contact problem or an unsuitable coating all produce failures that look like weak cartridges. If the fault appears in one batch of reused units under otherwise stable conditions, look at the cartridges. If it appears with every option at the same point on every pack, look at the line. Make the diagnosis reproducible before you commit to a new supplier — the diagnostic order for adhesion failures follows the same logic.

And treat absolutes as promises nobody can keep. “Never clogs” and “runs a shift without a single interruption” cannot be independent of equipment, ink, storage and environment. Read them as design aims to verify, not as permission to skip a full-shift trial. A supplier who documents batches and inspects before shipping is simply easier to hold to that standard — which is why we publish our own inspection routine.

Illustrative case: from a price request to a usable specification

A packaging contractor prints serial numbers on coated paper sleeves. The original request says only “black TIJ cartridge, 42 ml”. A seller quotes a very low price for repeatedly refilled units. Bench samples look fine. In production, some sleeves lose strokes while others smear when stacked. The contractor cannot tell whether the head, the ink, the coating or the head-to-product distance is responsible.

So it stops ordering against that description and rewrites the request: exact printer, new versus reused head, ink formulation, a coated sleeve sample, the code file, production speed, stacking interval and the inspection rule.

Two new-head candidates and one refill option with transparent history are tested in small quantities. One new-head cartridge jets well but resists smearing poorly. Another meets the sleeve requirement under the agreed trial. The buyer takes the second and keeps the record for future deliveries. These outcomes are illustrative — not customer data, and not a promise for another plant.

Compete on the same definition of success

The lesson is not “always buy the most expensive cartridge”. It is “make every seller compete on the same definition of success” — readable codes, an acceptable number of interruptions, material compatibility, and a process for resolving a bad batch. Once those terms exist, haggling gets somewhere, because you know what you are buying.

Price differences here usually trace back to printhead history, ink chemistry, application testing and support. Second-fill and repeatedly refilled units deserve the closest scrutiny, because adding ink cannot reset a used head. A newly built cartridge is the sensible baseline when production reliability matters — but it still has to pass a fair test on your line.

Send us the machine details, the finished pack, the artwork and the line speed before you compare bids. Then buy on measured cost per accepted code rather than on a product photograph. You can send us the pack and the code file to start.

Once you have two comparable quotes, ink cartridge HS codes for your invoice covers the customs side, and date and batch coding on your line shows what the first production run should look like.
