Measurement of print-through

Print-through is an unwanted effect when you see some of the ink from the opposite side of a paper in a magazine. It is a combination of the show-through (=effect from opacity) and the strike-through (=effect from ink penetration), both properties are closely related to the paper structure

Purpose

Print-through is an often-encountered print quality problem mainly caused by ink penetration and insufficient opacity of the paper.
Non uniformity in substrate structure relates closely to print-through. Therefore, spatial variations of print-through provide a probe to the substrate’s structure.

The print through measurement can be used to:

  • Check if the print through is acceptable and stable over time
  • Benchmark to competitors
  • Monitor how new settings in the productions affect the print through
  • Check if new products are better or not

Method

The measurement gives:

  • Assessment of the print quality and it's relationship with paper’s structure in an effective, reliable, fast and intuitive way, using an affordable standard flatbed scanner
  • Quantitative characteristics of print-through over a big area, both in average and in detail
  • Quantitative evaluations of print-through and its components:  show-through, strike-through, the relationships between the print-through phenomenon and the underlying physical properties and quantities

Deliveries

Histograms of reflectance, light absorption, light scattering, and depth of ink penetration. The calculated numbers are saved as ASCII-files for import to Excel or another spread sheet software.

Preparations

Send samples consisting of printed areas of size at least 10 x 10 mm (preferebly larger), and also unprinted areas. The printed samples should preferably be printed using black ink since this is more decisive. The sample size should be at least 100 x 100 mm. Note: Printed text can't be analysed using this method.
