Engineering & Manufacturing

Prepress handling for drawings and documents: merge, split, rotate and crop, N-up/imposition/booklet, grayscale to save ink, 300 DPI print preflight, and PDF/A archiving for consistent output.

Best for: Engineering, manufacturing, prepress and document control

The usual order: merge or split the drawing set, convert to grayscale or impose the sheets, then compress and linearize for distribution.

1Merge drawings and specs, then correct page orientation
2Crop, resize and lay out N-up/imposition/booklet
