Print through software

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

Cause

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 software 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

This tool provides an 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 with these parts:

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

Deliveries

License of the software package Print Through and a reflectance calibration set, a black NCS-sheet.
Manuals describing installation, scanning and evaluation (in English).

Delivery time

Delivery of the software within 6 weeks after order

Preparations

The needed equipment is: A a standard PC equipped with Win 7 or Win 10, a professional flatbed scanner, the Print-through software, a black NCS sheet and a calibration set.

The customer needs to buy the PC and the scanner and Microsoft Excel is recommended to use to open the result files but also other spread sheet software with ability to open Tab separated ASCII-files works.
RISE will upon request recommend a scanner model.
