Innovative date‐coding technique

Abstract

Purpose

Describes the properties and uses of a new colour‐change chemical for laser‐printing of human and machine‐readable data.

Design/methodology/approach

Presents the characteristics and modes of application of the chemical, its advantages over the current techniques of inkjet printing and laser‐marking, and a number of applications which show its distinctive features.

Findings

This chemical gives faster throughput and better print clarity than existing laser scribing processes, and opens up new anti‐counterfeiting techniques.

Originality/value

Draws attention to an invention that will make an impact on factory date‐coding procedures.
