Why?
The Esko Bitmap Viewer is a specialized, high-resolution quality control tool designed for verifying RIPped (LEN or TIFF) data in packaging and printing, reducing material waste by identifying errors pre-production. It provides advanced technical checks for dot gain, screen ruling, and file comparison, with recent versions supporting both Windows and macOS, often bundled with the Esko Imaging Engine.

A customer complains that a thin serif font dropped out in the last run. The prepress operator opens the 2400 dpi 1-bit TIFF in Esko Bitmap Viewer 10, zooms to 800%, and immediately sees that the RIP choked on the serif, rendering it as a single pixel. They adjust the RIP’s minimum dot size and re-RIP.
