Here are some common causes: Inconsistent Heat Distribution: One of the primary reasons for powder sticking on the film is inconsistent heat distribution during the curing process. If the heat press or curing unit does not evenly distribute heat across the substrate, certain areas may receive excess heat, causing the powder to melt and adhere to the film. Incorrect Curing Temperature and Time: Setting the wrong temperature and time parameters for curing can lead to powder sticking issues. Insufficient heat or inadequate curing time may result in incomplete melting of the powder, leading to poor adhesion to the substrate and subsequent sticking to the film.
Poor Quality Powder: The quality of the powder used in DTF printing plays a significant role in the final outcome. Low-quality or contaminated powder may not melt uniformly or adhere properly to the substrate, increasing the likelihood of sticking on the film. Improper Application Technique: Incorrect application techniques, such as using excessive pressure or applying the powder unevenly, can contribute to powder sticking issues. It's essential to follow manufacturer guidelines and ensure egypt email list consistent and uniform application of the powder onto the adhesive layer. Humidity and Environmental Factors: Environmental conditions, such as high humidity levels, can impact the curing process and affect the adhesion of the powder to the substrate.
Excessive moisture in the air may hinder the proper melting of the powder and increase the risk of sticking on the film. Substrate Compatibility: Certain substrates may be more prone to powder sticking issues than others. Factors such as surface texture, composition, and pre-treatment can influence the adhesion of the powder and its tendency to stick on the film during the printing process. Troubleshooting Tips: To address powder sticking issues in DTF printing,Calibrate heat press or curing unit to ensure uniform heat distribution. Verify and adjust curing temperature and time settings according to manufacturer recommendations.
