Heat transfer glossary

Accumulating drift

A position error that grows from cycle to cycle, often associated with pitch, slip, sensing or actual-travel inconsistency.

Consecutive-part release

Approval based on a defined run of consecutive products that can reveal drift and repeatability, rather than one acceptable piece.

Contact band

The narrow active zone where a roller, film and supported product meet during rolling transfer.

Contact path

The route followed by the active contact area across the intended decoration surface.

Contour-following contact

Profile-following

A coordinated motion method that keeps the contact tool aligned with a surface whose height or direction changes.

Datum

Reference

A physical reference used to repeat the position or orientation of a part, tool, web or machine motion.

Dry cycle

No-process trial

A controlled machine cycle used to check motion, return positions, clearance and material paths before final process energy is applied.

Effective contact time

Dwell at contact

The time during which the qualified contact area actually receives heat and load, not simply the full machine-cycle time.

Energy isolation

Lockout preparation

The control and verification of electrical, pneumatic, thermal and mechanical energy before inspection or maintenance.

Evidence chain

A traceable link from source material to a reviewed technical statement and its public derivative, with the limits of each source kept explicit.

First article

The first product evaluated against defined position, appearance, adhesion and deformation criteria after setup or changeover.

Fixed offset

A position error that remains similar in direction and amount across consecutive cycles, usually pointing to a datum or fixed stop relationship.

Fixture

Jig

The device that locates, supports and resists process load on the workpiece during decoration.

Flat pressing

A contact method in which a flat heated head or platen closes onto a supported flat work surface.

Heat transfer printing

Heat-transfer decoration

A decoration process that uses controlled heat and contact to transfer a prepared image layer from film to a product surface.

Heat-transfer film

Transfer film

A carrier film containing the prepared decoration layers that are transferred under the qualified process conditions.

HMI

Operator interface

The operator interface used to view and enter machine commands; a displayed field does not by itself prove that the related hardware is installed or qualified.

Hot stamping

Foil stamping

A process that transfers a foil layer to a product through a heated tool, pressure and controlled contact time.

Hot-stamping foil

Stamping foil

A layered foil whose transferable layer is released onto the product under heat, pressure and contact time.

Indexing

Controlled movement from one defined station position to the next, commonly used on turntables and repeat-position lines.

Machine recipe

A stored set of controller commands for a known setup; it does not restore physical tooling, material paths, guarding or product identity by itself.

Pad-head heat transfer

A heat-transfer method in which a compliant silicone head carries heat and presses film onto a locally curved surface; it is not ink pad printing.

Peel line

The moving boundary where used carrier film or foil separates from the decorated product after contact.

Process window

The range in which material, geometry, temperature, contact load, time and motion produce an acceptable and repeatable result together.

Profile learning

A coordinated calibration that relates the fixture datum, product pose, selected recipe and following path for a changing contour.

Registration mark

Eye mark

A printed feature intended to create one repeatable sensing event for a defined decoration repeat.

Rolling contact

Roll-on heat transfer

A moving contact method in which a heated roller progressively builds a narrow contact band across the decoration path.

Safety clearance

The verified free space required for one mechanism to move, retract or hand off a part without collision or trapping.

Segment compensation

Angle-segment compensation

A local path correction used only after relearning when a defect still repeats at the same contour segment.

Station handoff

The transfer of a workpiece and its required position state from one process station to another.

Substrate

Product material

The product material and surface that receive the transferred image or foil layer.

Take-up

Rewind

The controlled collection of used film, foil or processed web after the required separation or process step.

Unwind

The controlled release of film, foil or product web from its source roll.

Warm trial

A trial with the intended material pair and stabilised process heat, used after mechanical checks and before production release.

Web guiding

The rollers and reference surfaces that maintain the intended lateral path and orientation of a moving web.

Web tension

The controlled tensile condition that keeps a moving web stable without creating stretch, wrinkles or unwanted feedback.
