Flattening is the process of converting all overlapping transparent areas to discrete, opaque areas to represent the look of the original transparency. Flattening retains the vector integrity of the objects as much as possible. However, flattening may rasterize some objects depending upon file complexity.
The following file formats (by their nature) do not contain native transparency.
- PostScript
- EPS
- DCS
- PDF 1.3 or earlier
- PDF/X-1a
Because these formats do not include native transparency, they do not gain any further benefits by using the transparency feature in Prinergy Workflow Packaging Automation Expansion Pack.
