In Océ Express WebTools you can select a setting to flatten transparency information in a PDF document before printing. The setting is used for PDF documents containing transparency information only.
You can choose between the following values:
[Quality]
Select this value if print quality is an important factor. The processing speed slows down and more memory is required.
[Speed]
Select this value if PDF processing performance is more important than print quality. Large and complex PDF files are processed faster and use less memory.
You can only change the transparency flattening, when the [PDF render engine] setting is set to [Adobe PostScript interpreter]. You can find this setting under [Preferences] - [Print job defaults] - [PDF - General].
