- Poor insulation: Poor insulation on your heat press can result in heat loss and inconsistent temperature, affecting the sublimation transfer process. Ensure your heat press is properly insulated and that the heat is evenly distributed.
2. The Wrong Type of Paper
Using the wrong transfer paper can significantly impact the sublimation transfer process and the quality of the final product. Here’s how using the wrong transfer paper can affect sublimation transfer:
- Poor ink absorption: If the transfer paper is not designed for the sublimation ink you’re using, it may not hold the ink effectively, leading to incomplete or faded prints. Use transfer paper compatible with your printer and sublimation ink to fix this.
- Ink smudging or blurring: If the transfer paper is not coated correctly or is too thin, it may be unable to hold the ink in place during the transfer process, leading to smudging or blurring of the image. You can fix this issue by choosing a transfer paper with a suitable coating to hold the ink properly.
- Inconsistent color transfer: If the transfer paper is not designed to release ink correctly, it may transfer ink unevenly or inconsistently, leading to color variations or inconsistent transfer in the final product. Use transfer paper designed to release the ink properly and transfer the colors evenly.
- Paper sticking to the substrate: If the transfer paper is not heat-resistant or is coated with an adhesive that is too strong, it may stick to the substrate during the transfer process, causing damage to the substrate or distorting the image. Therefore, ensures the transfer paper you’re using is designed to release easily from the substrate.
- Lower durability: If the transfer paper is not designed for use with the specific substrate, it may not bond properly, resulting in lower durability, peeling, or lack of transfer. Your transfer paper should be designed for your specific substrate and sublimation ink.
3. Faulty Printer
Another reason your sublimation is not transferring could be the printer you’re using. Moreover, a sublimation printer plays a crucial role in the sublimation transfer process, and it can significantly impact the quality of the transfer. Here are some ways in which a sublimation printer affects transfer and how to fix them:

Moreover, using ink not meant for sublimation can also cause your sublimation not to transfer. Only use sublimation ink and ensure it’s specifically designed for your printer model.
- Ink distribution: The printer head should distribute the ink evenly and accurately to create high-quality prints. If the ink is not distributed correctly, it can cause issues such as streaks, smudging, or color bleeding. To fix this, check your printer’s print head and nozzles regularly to ensure they are clean and functioning correctly. You can also adjust your printer settings to optimize ink distribution.
- Resolution and color accuracy: The printer’s resolution and color accuracy can also impact the final print’s quality and how well designs transfer. Higher resolution and better color accuracy will produce better prints and better transfers. Therefore, ensure your printer settings are optimized for the highest resolution and color accuracy your printer can manage. Also, ensure the transfer paper is compatible with your printer and ink and can handle high-resolution prints.
- Poor printer maintenance: Regular maintenance ensures optimal performance and good print-quality transfers. Neglecting maintenance tasks such as cleaning or replacing parts can lead to clogged ink nozzles, inconsistent ink distribution, or poor print quality. Follow the manufacturer’s recommended maintenance schedule and perform regular cleaning and maintenance tasks to fix this.
Design and Image Issues That could Affect Transfer
Another factor that can impact sublimation transfers is the quality of your design or image quality.

Using a low-quality or low-resolution image for sublimation transfer can result in poor print quality and a lack of detail in the final product. Here are some ways it can affect sublimation transfer and how to fix it:
- Blurry images: Low-resolution images can appear blurry or pixelated when printed, lacking detail and sharpness. Ensure you use a high-resolution image suitable for the final print size.
- Jagged edges: Low-quality images can have jagged edges, also known as aliasing, which can appear more prominent when printed. Avoid jagged edges using image editing software to smooth out the edges or use vector-based images.
- Color distortion: Low-quality images can distort colors, leading to inaccurate and inconsistent colors when transferred. Use high-quality images with accurate colors and a color calibration tool to ensure accuracy and consistency in your transfers.
- Low-resolution image: Low-quality images may not transfer well onto the substrate, leading to incomplete or distorted prints. Therefore, use high-quality images and transfer paper designed to hold the ink correctly and transfer your designs accurately.
2. Inadequate Image Sizing or Placement
Inadequate image sizing or placement can significantly impact the success of your transfer and the final product’s quality. Here are some ways it can affect sublimation transfer and how to fix the issues:
- Wrong image size: If the image is too small, too big, or not properly placed on the transfer paper or substrate, this may affect the transfer. Such sizing and alignment mistakes can cause missing or distorted parts of the transfer. Ensure the image is sized correctly and positioned properly on the transfer paper and substrate before sublimating.
- Wrong aspect ratio: If the image is improperly sized and formatted, it can become distorted or stretched during the sublimation transfer process. This can cause the image to appear pixelated or blurry. Ensure the image matches the desired final product size properly and that the aspect ratio is correct for a good transfer.
- Cropped or off-center images: If the image is not centered or properly aligned on the transfer paper, it can result in a cropped or off-center look. Properly aligning and centering your designs on the transfer paper before starting will help you achieve better transfers.
Fabric and Material Issues That Could Affect Transfer
The material you’re transferring your image onto can also affect the quality of your sublimation transfer. Here are some things to consider:
1. Non-polyester or Polyester-coated Material
Non-polyester or polyester-coated materials can significantly affect sublimation transfer. Here are some ways it can affect sublimation transfer and how to fix the issues:
- Lack of polyester: Sublimation ink is designed to bond with polyester fibers, so non-polyester materials will not absorb the ink properly. This can result in poor image quality or a complete lack of transfer. To fix this issue, choose a substrate made of polyester, is 60% infused with polyester, or has a polyester coating.
- Ink bleeding: Non-polyester materials may not hold the ink properly, leading to ink bleeding or feathering, which can cause the image to appear blurry or distorted. Ensure you use a substrate compatible with your sublimation ink to avoid this issue.
- Heat resistance: Non-polyester materials may not withstand the high heat required for sublimation transfer, resulting in fading, discoloration, or a lack of transfer. Ensure the substrate you use is suitable for sublimation transfer and can withstand the required heat.
2. A Rough or Uneven Surface
A rough or uneven surface can significantly affect sublimation transfer, as it can cause the image to appear distorted or incomplete. Here are some ways it can affect sublimation transfer and how to fix them:
- Complex substrate surface: A rough or uneven surface can cause the transfer paper not to contact the substrate fully, resulting in an incomplete transfer. This can leave blank or distorted areas on your substrate. Choose a substrate that has a smooth and even surface to make the transfer process more convenient.
- Substrate finish: A rough or uneven finish on a substrate’s surface can cause the image to appear distorted or blurry. This is partly because the transfer paper does not make full contact with the substrate, and the substrate’s surface is not smooth enough to receive the image properly. Use a substrate with a smooth finish and an even surface to allow proper ink penetration and transfer, as well as mitigate distortions.
- Ink distribution: A rough or uneven surface can cause the ink to distribute unevenly, resulting in an uneven transfer on your substrate. A smooth substrate with an even surface will receive the ink evenly for a better transfer.
3. Non-white or Light-colored Fabric
Non-white or light-colored fabric can affect sublimation transfer depending on the fabric’s color and the design you’re transferring. Here’s how and some potential fixes.
- Color distortion: If your base fabric’s colors are distorted, this will affect the appearance of the transferred image. When sublimating onto non-white or light-colored fabrics, their color can mix with the ink’s color, causing distortion. You can try to fix this by using color correction software to adjust the image’s color before printing, but ultimately, the best fix is using a more neutral base.
- Image clarity: Light-colored fabrics can make the transferred image appear less vibrant and clear, making it difficult to distinguish small details even when the transfer is successful. Use a white base layer or a white underbase to make the colors appear more vivid.
- Contrast: Darker images may not contrast well on lighter fabrics, making them appear less noticeable after the transfer. Adjust the image’s contrast before printing, or use a white underbase to make the image stand out.
4. Fabric content inconsistencies
Fabric content inconsistencies can affect sublimation transfer in several ways, which may not always be possible to fix. Here are some ways it can affect sublimation transfer.
- Material ink absorption: Fabric content inconsistencies can cause the ink to be absorbed unevenly, resulting in the uneven color transfer or blotchy areas. Choose materials with consistent content and quality fabrics, and perform a test run to ensure designs transfer evenly.
- Fabric quality: Fabric content inconsistencies and their quality can also result in poor image quality and partial transfers. The ink may not penetrate the entire fabric fully, causing the colors to appear dull or washed out. Use a high-quality fabric designed for sublimation transfer.
Dye-Sublimation Ink Issues That Could Affect Your Transfer
Dye-sublimation ink is a crucial component of the sublimation transfer process, and any issues with the ink can affect the quality of the transfer. Here are some things to consider.
1. Expired or Old Ink
Expired or old ink may not produce accurate colors, making images appear dull or distorted. This is because the dye in the ink may have degraded, causing the colors to fade or shift, resulting in grainy or pixelated transfers. Use fresh, high-quality ink for the best results.
2. Inconsistent Ink Density
Inconsistent ink density can also affect the quality of your transfer. It can cause uneven color distribution, fading, or even blotchy patches on your prints. Ensure you use high-quality ink with consistent density for the best print and transfer results.
3. Clogged Print Head
Inconsistent or expired ink can also clog your print head, causing inconsistent ink density or a complete failure of your printer. You cannot transfer an image you cannot print. Therefore, clean your print head regularly to avoid this issue.
