WORKFLOW & QUALITY CONTROL
Sample Approval and Change Control
Quick Answer
Record the approved file, size, position, colors, materials and finished appearance. Check later changes against that record. Test and approve changes that can affect the result before continuing the order.
Build the approval sample record
Record the approved file, dimensions, placement, colors, materials and setup. Keep the accepted sample with the order reference.
Inspect placement, dimensions, color alignment, edges, coverage, distortion, thread condition and the reverse. Keep failed and approved samples when comparing changes. One controlled sample does not guarantee sustained output, other materials or an untested machine revision.
- Record the full test conditions
- Inspect preparation and the finished result
- State what the evidence does not prove
Define acceptance criteria
Agree on the checks used to accept the work, including appearance and dimensions. Describe unacceptable results clearly enough to guide production.

- Record the full test conditions
- Inspect preparation and the finished result
- State what the evidence does not prove
Lock file and material revisions
Keep the approved file and material specification identifiable. Check revisions before loading a file or substituting materials.
Define what is checked, when it is checked and which approved file and sample are used. State what stops the batch. Record file, material, thread, needle, backing or setup changes, and require new approval when they can affect placement, appearance or repeatability.
- Record the controller and software revision
- Keep the approved source file and exported production file
- Verify the screen result before releasing the job
Manage customer and production changes
Record who requested each change and what it affects. Check customer approval and production requirements before using the changed setup.
Define what is checked, when it is checked and which approved file and sample are used. State what stops the batch. Record file, material, thread, needle, backing or setup changes, and require new approval when they can affect placement, appearance or repeatability.
- Describe the recurring work
- Confirm the relevant model and configuration
- Record the condition that still needs verification
Re approval triggers
Review changes to size, placement, file, thread, needle, backing or material. Require another sample when the change may alter the accepted result.
Define what is checked, when it is checked and which approved file and sample are used. State what stops the batch. Record file, material, thread, needle, backing or setup changes, and require new approval when they can affect placement, appearance or repeatability.
- Keep an approved file and sample
- Place checks at high risk handoffs
- Stop, correct and reapprove before restarting affected work
Rework review
Record where defects began, how much work was affected and the corrective action. Use the findings to improve the relevant step without hiding rejected output.
Define what is checked, when it is checked and which approved file and sample are used. State what stops the batch. Record file, material, thread, needle, backing or setup changes, and require new approval when they can affect placement, appearance or repeatability.
- Compare the same delivered configuration
- Separate included items, options and buyer supplied work
- Keep return assumptions owned by the buyer
Frequently asked questions
When should I confirm details for the exact model?
Confirm model specific field, frame, controller and safe settings when they affect approval. General quality checks do not confirm machine compatibility or permit changes outside the model instructions.
What should I record for sample approval and later changes?
Label the approved sample with the file version, size, placement, colors, materials and setup. Record later changes and approval before the changed file or material enters production.
