What does diamonding mean?
Diamonding is a largely technical term describing the process by which something skews or twists out of square into a rough diamond, or rhombus, shape. Its most established use is in the printing and paper-converting industries, where it names a common defect: sheets of paper that absorb moisture unevenly or are fed misaligned can distort as they travel through a press, their corners no longer forming true right angles, resulting in poor registration and wasted stock. Press operators speak of correcting or preventing diamonding by controlling humidity, adjusting guides, and ensuring even tension. Beyond this trade context, the word can be applied loosely to any arrangement or deformation in which elements take on a diagonal, diamond-like orientation, though such uses are relatively rare. Derived from the familiar noun "diamond," which ultimately traces back through Greek and Latin roots also underlying "adamant," diamonding carries no strong emotional connotation; it is a neutral, descriptive term valued for naming a specific mechanical problem precisely. Readers encountering it will almost always be in a printing, packaging, or materials-handling setting.
A skewing distortion, particularly of paper sheets in a printing press, in which the sheet twists so that its corners form oblique rather than right angles.
"Persistent diamonding was traced back to uneven humidity in the paper warehouse."
Used almost exclusively in printing and paper-converting contexts.
The act or result of arranging or deforming something into a diamond-shaped, diagonal pattern.
"The lattice work featured a pleasing diamonding of the slats."
In print shops, 'diamonding' has nothing to do with jewels — it's what happens when a damp sheet of paper twists askew and refuses to run square through the press.

Etymology of diamonding
Diamonding derives from the English noun "diamond," which entered Middle English from Old French "diamant," itself from Late Latin "adamas, adamantem" (hardened steel, the hardest metal), borrowed from Greek "adamas" meaning unconquerable or invincible. The suffix "-ing" converts the verb formed from this noun into a verbal noun denoting a process. The specific industrial sense referring to skewed paper sheets developed within the printing trade, where the shape of the distorted sheet suggested a tilted rhombus or diamond.

How diamonding is actually used
Primarily a technical term used in the printing, paper, and converting industries; outside those trades it is uncommon and usually understood only from context. It functions chiefly as a gerund derived from the verb "to diamond."
Easily confused with diamonding
"Diamond" is the gemstone or geometric rhombus shape itself, while "diamonding" names the process by which something becomes skewed into that shape.
