For larger prepress houses, the standalone Bitmap Viewer is a luxury; the integrated one within is a necessity.
: Use the viewer to verify RIPped data (LEN or TIFF files) for content accuracy before output. bitmap viewer esko
Whether you are using a CDI plate setter or a digital press, the bitmap is the final "truth." The viewer helps identify: Tiny, unintended dots that cause dirty printing. Breakout points: Where a gradient drops to zero. For larger prepress houses, the standalone Bitmap Viewer
Esko Bitmap Viewer reads the specific screening information (LPI, angles, dot shapes) used in flexography and offset printing. It allows the operator to see exactly how the RIP has interpreted vector curves. A smooth curve in a vector file becomes a jagged stair-step in a bitmap; the viewer ensures these steps are within acceptable tolerance for the printing resolution. Breakout points: Where a gradient drops to zero

It is typically bundled with Esko Imaging Engine and can be accessed through Esko Automation Engine.
: Automatically highlights differences between two versions of a job, making it easy to track changes or verify corrections.
