PackDot vs Electronic Circuits Calc Pro
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
PackDot
This utility app helps create an inventory for flexographic plates and presses by measuring screen dots, dot diameter, and ink percentage from photos. It offers overlay functions to compare plates with anilox or printed materials, and can read angles and spot colors.
- Flexographic plate inventory
- Screen dot measurement (LPC/LPI)
- Dot diameter and area/ink percentage calculation
- Overlay function for comparison
- Reading angle and spot colors
- PDF report generation

IMPORTANT: Necessary a coaxial light microscope and a WIFI radial light microscope. To take photos is necessary a LOGIN, visit our web site. We sell a complete tools kit to work with this app, visit our web site: www.flexostore.co.uk This APP create a complete inventory for Flexographic Plates and flexo, offset ou gravure press. The PDF reports, are shared by social networks or email. Measure the dots screen (LPC/LPI), the dot diameter and the area/ink percentual, just taking a photo coupling a metallurgical microscope or using a WIFI microscope. Now with overlay function, to see plate over anilox or plate over printed. Now reading angle and spot colours.
