Product Overview

Summary: This Colour Matching Standard Operating Procedure provides a clear, repeatable method for achieving consistent colour results across paints, coatings, inks, textiles and finishes. It standardises how colours are specified, mixed, checked and approved, helping Australian businesses reduce costly rework, complaints and brand inconsistency.

Colour accuracy is critical wherever products are painted, coated, printed, dyed or branded. Small variations in batch, substrate, lighting or operator judgment can result in visible colour shifts that damage brand reputation, trigger client complaints and lead to expensive rework or scrapped product. This Colour Matching Standard Operating Procedure establishes a disciplined, documented process for how colours are requested, formulated, mixed, measured, adjusted and signed off within your operation.

Designed for Australian manufacturing, printing, coatings and textile environments, this SOP defines the tools, tolerances and communication protocols needed to manage colour reliably from job to job and site to site. It covers practical elements such as standard light sources, use of spectrophotometers and colour charts, batch labelling, sample retention and handling customer-supplied standards. By embedding this procedure, businesses can reduce subjectivity in colour decisions, improve right-first-time performance and demonstrate robust quality control to customers and auditors alike.
