Artwork file preparation checklist
To guarantee a flawless print finish and prevent production delays, please ensure your uploaded files or single graphics adhere strictly to these trade specifications:
Resolution & Pixel Clarity
- 300 DPI Minimum: All raster graphics and PNG images must be exported at 300 DPI at the final print size. Lower resolutions (72 DPI or 150 DPI) will result in pixelated or blurry print edges.
- CMYK Color Mode: Design and save your artwork using the CMYK color space. Files submitted in RGB will be converted automatically, which can cause shifts in color vibrancy and shade accuracy.
Color Profiles & Matching
CMYK Color Mode: Design and save your artwork using the CMYK color space. Files submitted in RGB will be converted automatically, which can cause shifts in color vibrancy and shade accuracy.
Background Transparency & Linework
- Transparent Backgrounds: Ensure your files contain no background fills, bounding boxes, or hidden white square layers unless they are meant to be printed.
- Minimum Line Weight: Hairlines and text strokes must be at least 1.5 points (0.5mm) thick to allow the white ink backing and adhesive powder to bond correctly to the film.
Wholesale Pricing & Scalable Volume Discounts
Our transparent trade structure scales down automatically as your workflow volume increases, allowing you to secure larger profits on bulk apparel runs. We feature an automatic mix-and-match system—your bulk tier discount is calculated based on the total cumulative metres across your entire cart.

Professional Heat Press Application Settings
Our custom barrier ink and film formula is engineered to be exceptionally Fast and Easy to Apply, resulting in a durable final print that will typically outlive the garment itself.
Follow these standard benchmarks for low-temperature application on heat-sensitive polyesters:
Step 1: The Initial Press Cycle
- Temperature: 133°C to 135°C (Low temperature protects polyester from heat bruising/scorching)
- Time: 5 to 7 Seconds
- Pressure: Medium
Step 2: The Peel Profile
- Peel Profile: Warm to Cool peel
- Pro-Tip: For the cleanest, most consistent results, leave the garment sitting flat on the lower platen of the heat press bed while executing your smooth peel.
Step 3: Crucial Heat Press Calibration
- The 48-Hour Rule: Please be aware that dye migration can take up to 48 hours to show on highly volatile or heavily dyed polyester garments.
- Test First: Because all commercial, manual, and pneumatic heat presses differ in their calibrations, always conduct a test press first. If you are unsure about a specific garment fabric or dye base, we strongly advise completing a sample press and waiting a full 48 hours to check for any slow color bleed before starting your main production line run.
