Quality Evaluation Service & General Print Quality

QUALITY EVALUATION SERVICE:

Printing consistently that produces quality results over time should be a habit and one of the strategic objectives of an advanced newspaper house. This objective is the most critical for the satisfaction of advertisers and readers of the newspaper. To achieve this goal, process control procedures and proven quality standards must be established and practiced.

The project aims to assess technical parameters and the general print quality of newspapers. This project / service will intend to evaluate the visual quality of the Newspaper (GPQ) based on the proven INCQC GPQ methodology by a WAN-IFRA consultant. Also, the technical evaluation of the printed cuboid will be carried out

 

A printed cuboid is evaluated for below parameters and evaluated against the ISO 12647-3 standards and WAN-IFRA target standards for the deviations.

  • News shade
  • Mid-tone spread
  • Dot gain 40%
  • Dot gain 70%
