: While historically a Windows-only tool, newer versions (since November 2021) are available for Mac. Alternatively, use the Automation Engine Viewer for a similar web-based experience.
The most powerful feature of the Esko Bitmap Viewer is its suite of , a collection of five specialized utilities designed to simulate real-world press conditions and expose potential production failures. These tools provide a level of insight that goes far beyond simple visual inspection.
You can overlay two different RIP results (e.g., a new version vs. an old one) to highlight even the smallest pixel differences. This is vital for "no-change" re-runs. 2. Ink & Channel Analysis bitmap viewer esko
The viewer allows users to toggle individual color channels (Cyan, Magenta, Yellow, Black) on and off. This separation is vital for checking:
To avoid highlight clipping or severe dot gain, operators must know the exact dot percentages in critical areas like gradients and vignettes. Bitmap Viewer features a densitometer tool that calculates the precise dot percentage of a selected area based on the pixel density, ensuring that 1% or 2% highlight dots will hold on the flexo plate. 5. Compare Tool (Difference Viewer) : While historically a Windows-only tool, newer versions
: Primarily runs on Windows , though specialized versions or licenses (like DotSpy) may allow for Mac usage.
Once verified, the files are safely released to CDI (Cyrel Digital Imager) flexo plate-setters or offset plate-makers. Conclusion These tools provide a level of insight that
: Toggle specific separations on and off to ensure traps are correctly built. 3. Technical Verification
By adding a bitmap check into your quality control workflow, you can catch critical errors that only manifest during the rasterization process:
