Sheaffer introduced the new Imperial pen line to its sales force in December, , along with the Compact Cartridge pen and the “Reminder” clip ballpoint. All of these new products followed the new angular Sheaffer profile, a design style established in by the introduction of the Sheaffer Pen For Men or PFM. Some of the Imperial pen models are close enough in design and features that they actually look like slender PFMs and thus are often confused with their bigger siblings. Sheaffer simplified the manufacture of the new Imperial by dropping the complex Snorkel filling system in favor of the simpler Touchdown system, a move that reduced the cost of the pen, though Sheaffer positioned the new pen in the premium price category, just below the PFM.

Writing ink sequencing — Examining intersections areas where two or more pen lines cross to determine the order of writing it may prove that a particular entry was added at a later time. Sequencing of indented impressions and writings — Examining intersections areas where the visible ink lines cross the indentations may determine the order of writing and thus prove that a particular entry was added at a later time.
Paper folds — It is often possible to determine whether an ink line that intersects a paper fold was written before or after the paper was folded. Offset marks — When two pieces of paper are pressed together, marks such as writing and printing may be transferred from one to another.

Such transfers will occur only when inks are freshly applied.
