Common questions
Why doesn't block-letter conversion fully disguise a writer's identity?+
Disguise by switching script form mainly interrupts the connected, cursive-specific movements between letters. Habits that are not tied to connection, such as consistent spacing between words, the proportion of letter height to width, and how dots and crossbars are placed, are more deeply automatic and tend to persist even in an unfamiliar script style.
How does an examiner compare a block-letter disguised sample to known writing?+
The examiner looks past the surface script change and compares the surviving class and individual characteristics, spacing patterns, proportions, pen pressure, and habitual letter formations, against known exemplars, ideally including any block-print exemplars from the same writer if available.
