Anisotropic Thermal Strain Mapping across Large Format Heated Platen Brass Die Chases
Pre-scaling brass die vector artwork based on directional thermal strain maps eliminates press registration drift across large format heated platens.
Compensating Substrate Moisture Contraction in Multi Pass Hot Foil Stamping
Substrate desiccation during heated stamping alters sheet dimensions, requiring differential die scaling and controlled humidity recovery between passes.
Predicting Dynamic Thermal Expansion and Matrix Creep in High Speed Foil Stamping Tooling
Predict dynamic thermal expansion and counterforce creep using alloy scaling factors and glass-transition temperature limits to maintain stamping register.
Paperboard Anisotropic Hygrothermal Expansion Mechanics in Converting Operations
Paperboard expands five to seven times more across the grain than along it, requiring precise humidity control and pass timing to maintain converting register.
Cold Foil Register Drift as the Stack Warms across a Shift
Stack thermal buildup causes substrate shrinkage and mechanical expansion, driving cold foil register drift across continuous production shifts.
