This content is tailored for the operation of xTool Appreal Printer & xTool OS1 Automatic Shaker Oven Machine with xTool Heat Press Series products or equivalent third-party heat press devices.
Overview
This guide helps you achieve optimal heat-press results—whether using xTool Heat Press Series or a compatible third-party heat press device—after printing and curing large PET film graphics via xTool Apparel Printer and OS1 Shaker Oven. It addresses:
- Creased Graphics: The final pressed design appears wrinkled or creased, even when the garment itself is smooth.
- Peeling After Washing: The design peels away from the fabric, especially after being washed, indicating poor adhesion.

Safety & preparation
- DO NOT touch the heated surfaces of the heat press machine—risk of burns.
- Press settings (temperature, pressure, time) depend on the garment material.
Recommended tool
- Heat Press Mat: Using a heat press mat (often made of foam or silicone) specifically designed for heat transfer applications is highly recommended.
💡 Ensure the mat is large enough for your garment and design, as it provides a smooth, firm surface that helps ensure even heat and pressure distribution.
Heat pressing procedure
Step 1: Pre-press the garment
This initial step removes moisture and wrinkles from the fabric, preparing it for a better transfer.
- Lay your garment flat on the heat press mat.
- Set your heat press to the same temperature you will use for the transfer.
- Press the garment for approximately 5-6 seconds.
Step 2: Apply the DTF transfer (Initial press)
- Carefully place the cured PET film with your design onto the pre-pressed area of the garment.
- Ensure the entire design is within the working area of your heat press.
- Confirm your time and temperature settings are correct for your material.
- Press the garment with the transfer film according to your material settings.

Step 3: Peel the film (Hot peel)
This is a critical step for a clean transfer and a smooth finish.
- After the initial press is complete, do not immediately peel the PET film away. At this stage, the ink and adhesive are not fully set.
- It is strongly recommended to let the garment and film cool down until the temperature is below 100°C (212°F). This typically takes 10-20 seconds.
- Once cooled, gently peel the PET film away from the design.
Step 4: Re-press the edges (Crucial step)
For large patterns, the edges and corners of the design often receive less pressure than the center, which can lead to peeling after washing.
Re-pressing these specific areas ensures a strong, durable bond across the entire design.
Secondary Press Cycle:
- Place the garment (with the design now transferred and the film removed) back onto a heat press mat.
- Perform a complete secondary press cycle under the same processing parameters as the initial press.
Edge Corner Re-pressing:
- Position each corner and edge area of the design in the center of the heat press working area.
- Re-press each area using the same parameters as the initial press.

Step 5: Final cooling & care instructions
- Cool Down: After the final press, allow the garment to cool completely to room temperature.
- Washing: Do not wash the garment immediately. It is best to wait at least 24-48 hours after pressing before the first wash.
- Storage: It is recommended to keep the finished work in a sealed bag with a desiccant packet to protect it from moisture.
