Can I use one ink across multiple product lines?

Trying to simplify ink inventory? This guide explains when one ink can be used across several packaging types—and when it can’t.

When it works

  • Products share similar materials (e.g. all PET or all cardboard)

  • Line conditions are consistent (speed, environment)

  • Ink is general-purpose (e.g. high-contrast MEK)

When it causes problems

  • Mixed materials (plastic + foil + glass)

  • Some lines need faster drying than others

  • Some surfaces repel ink (e.g. oily, coated)

Decision checklist

Factor Ideal for multi-use?
Adhesion on all substrates ✅
Meets all drying speeds ✅
Compliant with all product types ✅
Consistent climate across lines ✅
 

Recommendation

Use general-purpose MEK only if adhesion and performance are acceptable across all lines. If not, consider two inks optimised for your main substrates.
