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.
• • For xTool Heat Press Series, consult Material Settings - xTool Selected DTF Film for the best results.

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.

Operation procedure

Step 1: Set parameters

Specific heat pressing parameters vary depending on the garment material. If using a Heat Press product, please refer to this link to select the appropriate parameters: https://www.atomm.com/zh/easyset/collection/RY001A?t=heatPress&n=Smart+Press+Platform

Step 2: Pre-press the garment

This initial step removes moisture and wrinkles from the fabric, preparing it for a better transfer.

1. Lay your garment flat on the heat press mat.
2. Set your heat press to the same temperature you will use for the transfer.
3. Press the garment for approximately 5-6 seconds.
4. Stop pre-press.

Step 3: Apply the DTF transfer (Initial press)

1. Carefully place the cured PET film with your design onto the pre-pressed area of the garment.
2. Ensure the entire design is within the working area of your heat press.
3. Confirm your time and temperature settings are correct for your material.
4. Press the garment with the transfer film according to your material settings.

Step 4: Peel the film (Hot peel)

This is a critical step for a clean transfer and a smooth finish.

1. 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.
2. 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.
3. Once cooled, gently peel the PET film away from the design.

Step 5: 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:

1. Place the garment (with the design now transferred and the film removed) back onto a heat press mat.
   
2. Perform a complete secondary press cycle under the same processing parameters as the initial press.
3. Take out the garment.

Edge Corner Re-pressing:

1. Position each corner and edge area of the design in the center of the heat press working area.
2. Re-press each area using the same parameters as the initial press.

Step 6: Final cooling & storage

• Cool Down: After the final press, allow the garment to cool completely to room temperature.
• Storage: It is recommended to keep the finished work in a sealed bag with a desiccant packet to protect it from moisture.

Step 7: Washing

• Please wait at least 24–48 hours after the heat press before the first wash.
• Use a mild, bleach-free detergent to prevent the pattern from fading or being damaged.
• It is recommended to wash the garment inside out to reduce friction between the pattern and the inner wall of the washing machine.
• Avoid using washing cycles that involve vigorous stirring or rubbing; a gentle mode is preferable.
• It is recommended to wash with water at room temperature or below 40°C; excessively high water temperatures may cause the design to fade or peel.
• Avoid using hot water or high-temperature drying to prevent affecting the design's durability.
• It is recommended to air dry or use low-temperature drying; avoid direct sunlight to prevent the pattern from fading or deforming.
