Moiré is the nemesis of rosette patterns. It occurs when screen angles interact incorrectly (e.g., Cyan at 15° and Black at 75° clash). While a soft proof on a monitor might look fine, the Bitmap Viewer reveals the ugly, weave-like interference pattern before it wastes ink and substrate. Bitmap Viewer Esko
Traditional PDF viewers often fail to show the complex interactions of screens, angles, and dots. The Bitmap Viewer fills this gap by providing: View individual halftone dots. : Users can preview job-critical data including screen
Esko is famous for its automated trapping solutions (trapping being the slight overlap of colors to avoid white gaps due to press misregistration). However, automated trapping is not infallible. Sometimes, the logic applies traps where they aren't needed, or misses them where they are critical. While a soft proof on a monitor might
When trapping (spreading one color into an adjacent color), the Bitmap Viewer reveals the true result. It shows whether the trap created a dark "peek" or a light halo. Furthermore, for reverse text (e.g., white text knocked out of a 4-color black background), the viewer exposes the "dirty" edges where adjacent color dots intrude into the text area. Operators can verify that the text remains legible at the actual print resolution (2400 dpi) rather than the screen resolution (72 dpi).
