Low-Temperature HTV Settings Chart
Start here when the blank has a lower heat tolerance, then confirm that the exact film is approved for that substrate.

How to use the Low-Temperature HTV Settings Chart
- Identify the exact material or garment.
- Read the complete row and its bracketed source key.
- Open the source and confirm the current manufacturer instruction.
- Run and record one test before repeating the setup.
Real-world examples
First sample
Inputs
- Exact product
- One sourced row
Result
A single test setup
Production check
Do not generalize the row to an unnamed substitute.
Units and parameters
Keep units consistent from design setup through pressing notes. When the tool provides a preset, use it as a planning value and replace it with the actual garment or blank measurement when possible.
| Input or rule | What it changes |
|---|---|
| Material | Read the material value in the same row; do not mix columns from different products. |
| Temperature | Read the temperature value in the same row; do not mix columns from different products. |
| Time | Read the time value in the same row; do not mix columns from different products. |
| Pressure | Read the pressure value in the same row; do not mix columns from different products. |
| Peel / source | Read the peel / source value in the same row; do not mix columns from different products. |
Rule and assumptions
Use the row for the exact named material or garment. Bracketed source keys identify the manufacturer or supplier table behind that row.
- Values apply to the named product or blank, not every material in the same category.
- Measure the actual garment or blank and test one item before a production batch.
- Press calibration, platen contact, seams, moisture, and finish can change a result.
Use this tool for
- Preparing a repeatable bench reference
- Comparing product-specific values before a test
- Recording the source used for an order
Worked example
Inputs
- One exact table row
- The linked source revision
- The actual blank or garment
Result
A sourced starting value and a written test note
When to use this
Before cutting or pressing a new product combination.
What to check before pressing
Confirm product name, substrate, source revision, press calibration, and platen contact.

Common mistakes
- Using a similarly named product instead of the exact row.
- Skipping the linked source when a manufacturer revises instructions.
- Repeating a batch before checking one sample and platen contact.

FAQ
Are the numbers in this low-temperature htv settings chart universal?
No. Each row is tied to the named material or garment and its bracketed source. Recheck the source and test the actual item.
Why do I need a test when the row has a source?
A source establishes the intended starting value. Press calibration, substrate variation, seams, moisture, and finish still affect the physical result.
How should I record a changed setting?
Keep the source value and the successful test value together with the product name, date, press, pressure method, and blank lot.
