Troubleshoot photo engraving previews

The Image controls are disabled

Select exactly one bitmap and check that the image and its layer are visible and unlocked. For traced outlines use vector Fill settings.

The picture looks washed out or too dark

Open Original / processed and compare the light and dark detail. Check whether Invert is enabled. Adjust one tone control at a time. If fine edges develop halos, reduce Sharpening and compare again.

The preview reports too many raster samples

The offline generator caps raster output at 250,000 samples per image. A larger image or closer spacing needs more samples. Increase Pixel / line spacing or reduce the image’s physical dimensions, then regenerate Preview.

The dots look different in Compare 12 modes

The comparison uses a small sample of the cropped image. Open Preview job to inspect the generated path at the chosen physical size and spacing. See Raster modes and dot patterns.
