12.7mm vs 25.4mm TIJ Cartridges: How to Choose
Choosing between a 12.7mm vs 25.4mm TIJ cartridge comes down to one question: how tall is the code you need to print in a single pass? A 12.7mm (half-inch) cartridge covers most date, batch and short barcode jobs, while a 25.4mm (one-inch) cartridge prints taller text, more lines or larger codes in one swath.
This guide explains what the two sizes mean, how they affect lines of text, which MufengTech coders use each size, and a simple step-by-step method to pick the right one for your production line.
What does 12.7mm or 25.4mm mean on a TIJ cartridge?
Print height is the maximum height of the swath that one thermal inkjet (TIJ) cartridge can print in a single pass. It is fixed by the length of the nozzle row on the cartridge, so it cannot be increased in software.
12.7mm equals 0.5 inch. It is the classic TIJ format used in most handheld coders and many online coders.
25.4mm equals 1 inch. It either comes from a single wider 25.4mm cartridge, or from two 12.7mm cartridges stitched together on a printer that supports two heads.
Within the available height, the coder can print any number of lines, so the content (dates, lot numbers, logos, QR codes) decides how much height you really need.

| MufengTech handheld coders | MFG50, MF-G100, MFG100E, MF-G300, MF-T110-H | MFT130 |
| MufengTech online coders | MFT180E, MFT110M (single 12.7mm nozzle) | MFT190 (single 25.4mm nozzle), MFT210E / MFT220E / MF-T260E (max 25.4mm), MFT220 (two 12.7mm nozzles) |
| Ink options | Water-based, solvent quick-drying, UV, invisible and food-grade cartridges | Fewer ink choices; check the 25.4mm ink cartridge page for your ink type |
| When to choose it | Small, sharp codes and the widest ink range | Tall or multi-line codes in one pass |
When a 12.7mm TIJ cartridge is the right choice
A 12.7mm cartridge is the right default when your code is small and the product is moving at normal line speed. Examples include an expiry date and batch number on a food carton, a production time on a cosmetic tube, or a short serial number on a cable.
The main advantage is choice. MufengTech offers 12.7mm cartridges in water-based ink for paper and cartons, solvent quick-drying ink for non-porous surfaces such as plastics, metal and coated films, plus UV, invisible and food-grade versions. If you are not sure which ink you need, a 12.7mm cartridge usually gives you the most options to test.
Handheld coders such as the MF-G100 handheld inkjet machine (print height 1–12.7mm, 150/300/600DPI) are built around this size, which makes it a practical choice for small workshops and warehouses.
When a 25.4mm TIJ cartridge is the right choice
Choose 25.4mm when the code simply does not fit in 12.7mm. Typical cases are four or five lines of text, a company logo next to the date, a larger barcode that must be scanned from a distance, or bold characters on a shipping carton that need to be read across a warehouse.
There are two ways to reach 25.4mm:
- One 25.4mm cartridge. For example, the MFT190 industrial inkjet printer uses a single 25.4mm nozzle, and the MFT130 handheld code machine prints up to 25.4mm.
- Two stitched 12.7mm cartridges. The MFT220 high-speed printer uses one or two 12.7mm nozzles to cover 1–25.4mm. This keeps access to the wider range of 12.7mm inks.
For codes taller than one inch, multi-head systems go further. The MF-T400E uses four heads for 50.8mm, and the MFT600 uses 1–6 nozzles for print heights from 38.1mm up to 76.2mm.
How to choose between 12.7mm and 25.4mm: 6 steps
- Write down the exact code. List every line: date, batch, time, shift, logo, barcode or QR code.
- Measure the space on the package. Check the flat or printable area where the code will sit, including any margin.
- Estimate the total height. Add character height for each line plus line spacing. If the total is clearly under 12.7mm, a 12.7mm cartridge is enough.
- Check the material and ink. Porous surfaces such as paper and cartons usually suit water-based ink; plastics, metal and glass need solvent ink. Confirm that ink is available in the size you want.
- Check line speed and resolution. TIJ trades speed for resolution: our cartridges reach up to 406m/min at 90DPI and about 60m/min at 600DPI. Higher resolution is sharper but slower.
- Test on real samples. Send us photos or samples of your product and the code layout. We can suggest a coder and cartridge and print a test where possible.
Print distance and image quality
Print distance is the gap between the cartridge nozzles and the product surface. TIJ works best close to the surface. Many 12.7mm handheld and online coders specify about 1–2mm, while several 25.4mm online models allow roughly 2–5mm. A taller head does not let you print from far away; if your products vary a lot in position or have curved surfaces with large gaps, a continuous inkjet (CIJ) printer may be a better fit.
Keep the product steady and the head square to the surface. With taller heads, a small tilt shows up more clearly as uneven density from the top to the bottom of the code.
Running cost and maintenance
Both sizes are cartridge-based, so there is no ink system to flush and no make-up fluid. When the ink runs out, you swap the cartridge and the nozzles are renewed with it. Ink use depends on the size of the code and the resolution you print at, not just on the cartridge size, so a larger code at high resolution uses more ink per print. Ask us for cartridge specifications for your selected model; MufengTech cartridges are typically 42ml.

FAQ: 12.7mm vs 25.4mm TIJ cartridges
Can a 12.7mm TIJ printer print 25.4mm high codes?
Only if the printer supports two heads that can be stitched together, such as the MFT220. A single 12.7mm cartridge can never print more than 12.7mm in one pass.
How many lines of text fit in 12.7mm?
It depends on font size. Within the 12.7mm print height the coder can print any number of lines; a typical layout is one to three readable lines of dates, batch numbers or a short code.
Is a 25.4mm cartridge sharper than a 12.7mm cartridge?
No. Sharpness depends on resolution (DPI), ink and print distance, not on the cartridge size. Both sizes can print high-resolution codes when set up correctly.
Which size should I choose for food cartons?
For expiry date and batch codes on cartons, a 12.7mm cartridge is usually enough and offers water-based, solvent and food-grade inks. Choose 25.4mm if you also need a logo, more lines or a large barcode.
