Q: What should I do if the image shows ghosting, blurring, or unclear edges?

Common Causes

• Material shifting during transfer: During flatbed pressing or calender transfer, if the transfer paper or fabric moves or slips, ghosting will occur.
• Surface contamination: Dust, fibers, or adhesive residue on the transfer paper, fabric, or heat platen can interfere with proper adhesion.
• Excessive material stretch or rebound: Elastic materials may stretch or rebound during pressing, causing image displacement.
• Excessive pressure: Too much pressure can cause the material to “grab” or shift on the platen.
• Press closing too fast: Especially on flat heat presses, a rapid closing action may momentarily lift the transfer paper, causing secondary contact before full bonding.

Solutions

• Secure all four corners of the transfer paper with high-temperature heat tape to prevent movement.
• Check and clean the heat platen, fabric, and transfer paper surface before pressing.
• Reduce pressing pressure to avoid excessive compression.
• Perform test prints on elastic materials and fine-tune parameters before production.
• Slow down the press closing speed if possible, or insert a protective sheet between fabric and platen.

Q: Sublimation is incomplete — colors look pale, grayish, or some areas fail to transfer. Why?

Common Causes

• Insufficient temperature or time: Heat energy is not enough for full dye sublimation.
• Uneven heat distribution: Long-term use may cause temperature variation across the heat platen.
• Material incompatibility: The coating or fabric composition may not be suitable for sublimation.

Solutions

• Regularly check and calibrate heat platen temperature.
• Ensure the material has a proper sublimation coating or adequate polyester content.

Q: Colors darken, shift, or water marks appear after heat pressing. Why?

Common Causes

• Moisture interference: Transfer paper, fabric, or padding absorbs moisture, which vaporizes during heating and disrupts color transfer.
• Overused padding: Old padding absorbs moisture repeatedly, increasing the risk of water marks.
• High ambient humidity: Common in rainy seasons or high-humidity regions.

Solutions

• Pre-heat fabrics to remove moisture before transfer.
• Store printed paper and materials in a dry environment.
• In high-humidity conditions, increase pre-heating time or replace moisture-absorbing padding.

Q: Some fabrics bubble, blister, or develop raised spots after heat pressing. Why?

Common Causes

• Special coating layers on fabric: Non-breathable coatings trap moisture or gas during heating.
• Excessive temperature or pressing time: Adhesive layers become over-activated.

Solutions

• Use segmented or patterned printing instead of full-coverage pressing.
• Lower the temperature and extend pressing time instead.
• Insert protective or isolation paper between fabric layers if necessary.

Q: Colors are correct, but print quality is unstable or inconsistent. What’s wrong?

Common Causes

• Aged or deformed padding: Uneven pressure leads to inconsistent transfer.
• Poor transfer paper quality: Unstable dye release affects color consistency.
• Inconsistent equipment pressure: Long-term use without calibration causes uneven results.

Solutions

• Regularly inspect and replace press padding.
• Use stable, high-quality transfer paper.
• Re-calibrate pressure settings to ensure uniform contact.
