The Hairline Correction feature thickens stroke lines within a
document that may be too thin for printing purposes.
The Remove color trapping layers option allows you to eliminate
color trap layers from the PDF. Color trap layers are originally
intended to provide fill between two objects that abut in a
document but end up printing with white space along the abutting
borders. Color trap layers solve the issue by printing an
overlapping border between the abutting objects.
