For TIJ packaging coding, water-based ink is commonly considered for absorbent paper and uncoated cartons. Solvent-based ink is commonly considered for selected non-absorbent surfaces. These are starting points: the actual coating, ink formulation and printer compatibility determine suitability.

Water-based or solvent-based: where to start?

• Water-based ink: Often used on porous and some semi-porous materials such as uncoated paper, corrugated carton and untreated wood. Absorption and evaporation contribute to drying. Coated or treated versions of these materials may behave differently.
• Solvent-based ink: Often considered for selected plastics, glass, metal and foil. Drying relies largely on solvent evaporation. A dry print can still have poor adhesion, so drying and resistance to rubbing must be checked separately.

Why coated packaging needs a sample test

A carton may have a laminated, varnished, waxed or other coated print area. Plastic may carry mould-release residue, oil or a surface treatment. Neither the base material name nor the word solvent guarantees adhesion. Some surfaces may require a different ink, print zone or marking method.

Inspect the exact print area for coating, moisture, dust and oil. Test the finished packaging, including its actual colour and texture. Do not assume that an ink suitable for one plastic pouch will behave the same way on another.

How fast will the ink dry?

There is no single drying time for every water-based or solvent-based TIJ ink. It depends on the formulation, amount of ink deposited, substrate, temperature, humidity and airflow. Test the time available before the next roller, packing step or handling contact. Dry-to-touch performance does not establish waterproof, chemical-resistant or permanent marking.

Can the printer accept both types?

Some BENTSAI models support specified water-based and solvent-based cartridges; others have more limited compatibility. Confirm the exact model, cartridge size, chip and firmware with PTS before ordering. Matching physical dimensions alone is not proof of compatibility. Malaysia-supplied cartridge names or chips may differ from overseas listings.

Care during work and idle periods

Follow the instructions for the selected cartridge, including capping, storage and approved nozzle cleaning. Both ink types require care. The permitted uncapped time depends on the formulation and working conditions. Avoid refilling or mixing inks unless expressly supported for that cartridge.

A practical acceptance test

1. Provide the actual packaging sample and intended print location.
2. Confirm the printer, compatible cartridge and code layout.
3. Print several samples using the intended settings and workflow.
4. Measure drying before the next handling step and inspect for smudging.
5. Check adhesion and the handling conditions that matter to your application; scan any barcode or QR code using the intended reader.
6. Record the accepted sample and settings before production.

Frequently asked questions

Does every glossy carton require solvent ink?

The coating must be evaluated. Solvent ink may be a candidate, but it is not guaranteed to adhere to every glossy surface.

Does primary packaging always need solvent ink?

No. Ink selection follows the actual print surface and cartridge compatibility, rather than the primary or secondary packaging label alone.

What information should I send to PTS?

Send the printer model, material or sample, coating details if known, print content, production speed and handling conditions. PTS can discuss available options and provide supporting product documents held for the proposed ink. Final suitability must be verified on your application.
