A visual reference is an image showing visible product, material, package or process context. A technical specification states measurable or document-controlled requirements. Both evidence types support sourcing, but each answers a different question and requires separate approval language.

What can an image legitimately communicate?

An image is evidence of visible content and composition. On the MFE site, approved photographs are named by what they show—sample room, production line, test equipment, hank or spool—and each image is used on one relevant page.

  • Visible colour and form
  • Equipment or sample-room context
  • Website composition and presentation

What belongs only in a specification record?

A specification record is the place for controlled values and conditions. Diameter in mm, tensile strength in kg or lb, linear density in dtex or denier and test method references should remain connected to their source and revision.

  • Named parameter and unit
  • Tolerance or acceptance range
  • Method, sample and document status

How are the two evidence types linked safely?

The link is a sample or project identifier, not visual similarity. As of 2026, MFE’s 8 public series and 139 supplied rows are presented independently from image appearance so a photograph cannot inherit technical values by proximity.

  • Assign a common project ID
  • Record image and data sources separately
  • Approve each evidence type for a stated purpose

Why does single-use image allocation help?

Single-use allocation is a content-governance rule that gives each photograph one clear buyer context. Our review found 50 approved WebP assets in the final site, with 50 unique visible placements, no missing references and no exact duplicate files.

  • Less visual repetition across pages
  • Clearer alt text and page intent
  • Simpler image audit and replacement history
