The type of ink that stays on plastic, based on the provided information, is #1250 All-Purpose Air-Dry Ink for Non-Porous Surfaces.
Effective Ink for Plastic Surfaces
Marking plastic and other non-porous materials can be challenging, as standard inks often smudge, rub off, or wash away easily. Specialized inks are designed to adhere effectively and create durable marks on these tricky surfaces.
One such ink identified for its performance on plastic is:
#1250 All-Purpose Air-Dry Ink
According to the reference, #1250 All-Purpose Air-Dry Ink for Non-Porous Surfaces is specifically formulated to create imprints that are:
- Rub-resistant: The ink doesn't easily wear off with friction.
- Waterproof: The marks remain intact even when exposed to water.
This ink is suitable for a variety of hard-to-mark surfaces beyond plastic, including:
- Glass
- Metal
- Polypropylene
- Rubber
- Other non-porous materials
Its air-dry nature means it cures upon exposure to air, forming a resilient bond with the surface without requiring heat or special equipment. This makes it a practical solution for applications requiring durable marking on materials like plastic containers, parts, or packaging.
