General Print Quality (GPQ) on random market copy

Objective

Maintaining consistent and high-quality printing is an essential objective for newspaper houses. It ensures the satisfaction of advertisers and readers while strengthening the publication’s reputation.

WAN-IFRA offers neutral and unbiased print quality assessment on random market copies that helps publications benchmark the quality scores, enabling publications to evaluate quality against competitors in the market. This approach helps newspapers identify areas for improvement and maintain excellence in print quality.

Quality assessment methodology:

  • GPQ Benchmarking: Quality evaluation on random market copies (self & competitor), collected random by WAN-IFRA.
  • Criteria: 16–20 color pages evaluated based on common pages. Two copies per test day/month evaluated. Can be customise to suit the company requirement. Final score benchmarked against % defects.
  • Confidentiality: Strict confidentiality maintained; reports not for publicity or litigation.
