Technical Alignment

Our tools support applications aligned with ASTM and ISO standards

Surface Energy & Viscosity Testing Standards (ASTM D4212 & ISO 8296)

At Kolorguide, our tools are used in industrial applications where consistency, repeatability, and process control are critical.

While we are not a certification body, our products and guidance are aligned with internationally recognized testing methods used across printing, coatings, packaging, and manufacturing industries.

What This Means for Your Process

Our focus is to support real production environments by providing tools that help:

• • Ensure consistent surface energy before printing or coating
  • Maintain viscosity control for repeatable application results
  • Reduce variability in production batches
  • Improve adhesion performance in films, foils, and coated substrates

Common Questions About Testing Standards

What is ASTM D4212?

It is a standard test method used to measure viscosity using Zahn cups in industrial applications.

What is ISO 8296?

It defines how to measure surface energy (dyne level) on plastic films and substrates.

Why is surface energy important?

It determines adhesion performance in printing, coating, and packaging processes.

Industrial Applications

Kolorguide tools are used across multiple industries, including:

• • Flexographic and gravure printing

• • Cosmetic and personal care packaging

• • Flexible packaging and labeling

• • Coatings and surface treatment processes

Technical Approach

We emphasize practical, repeatable measurements that can be integrated into daily production workflows.

This approach allows operators and quality control teams to make faster, more reliable decisions based on measurable parameters rather than assumptions.

If you have a specific application, our team can help guide you in selecting the appropriate testing method and tools.
