SIMPALAB

Dirt analysis Software

SIMPALAB — Dirt analysis Software

SIMPALAB is the Dirt analysis Software from Techpap for the accurate measurement of ink, shives, stickies, and other impurities.

Functions and Workflow

SIMPALAB is a single software for the accurate measurement of impurities, following a clear workflow:

  • Scanner command
  • Image aquisition
  • Image Processing
  • Statistical calculation
  • Interpretation of results
  • Management of obtained data and results export

Key Features & Highlights

The software is described as remarkable and acknowledged user friendly and offers complete and thorough image treatment, developed as a CTP (Computer-to-Plate) software.

  • User-Friendly Interface:
    • View window for impurities (e.g., black dots, tinted fibers) marked by coloured squares.
    • Table showing all detected impurities, with possible sorting per type, size, and contrast.
    • Every impurity can be visualised with a single click.
  • Conformity with Norms:
    • ISO 53501, ISO 53503, ISO 21993 (norm in progress).
    • INGEDE Meth. 2, INGEDE Meth. 4.
    • TAPPI T 563.
  • Image Treatment:
    • Unwanted contrasts, shadows, and ripples can be corrected with mathematical treatment (« adaptative threshold by Gaussian approximation histogram »).
    • This provides a homogeneous measuring process, reliability, and repeatability.
  • Processing Speed: Less than 10 minutes to proceed with 10 measurements (A4 sheet with 600 ppi resolution).
  • Family Designation / Thresholding:
    • Dedicated particular window for desired family parameter (specific to a scanner, type of measurement, and/or type of paper).
    • Thresholding can be done according to size for each dimensional class separately; large spots with low contrast can contribute, as small spots will be rejected unless highly contrasted.
    • The « equivalent black area » mode («EBA») can be chosen according to ISO 53504 and Tappi T 563 and activates with a single click.
    • For ISO 53501 and INGEDE4, families are ready-made.
