Why is My Black Sublimation Turning Brown? Explained!

Understanding the Sublimation Process

Before we delve into the reasons behind black sublimation turning brown, let’s first understand what sublimation is. Sublimation is a printing technique where heat and pressure are used to transfer dye onto various materials. This process involves turning the dye into a gas, which then binds with the fibers of the material, resulting in vibrant and long-lasting prints.

Possible Causes of Black Sublimation Turning Brown

Incompatible Sublimation Inks

One common reason for black sublimation turning brown is the use of incompatible sublimation inks. Different ink brands or types have varying chemical compositions. Using an ink that is not specifically designed for sublimation or is not compatible with your printer and paper can lead to color changes, including the black color fading into brown.

Incorrect Temperature and Pressure Settings

The sublimation process requires precise temperature and pressure settings for optimal results. If the temperature is too high or the pressure is too low, it can cause the black dye to oxidize, resulting in a brownish color. Additionally, incorrect timing or insufficient heat can also contribute to color distortion.

Inadequate Dye Sublimation Transfer Time

Another factor that can cause black sublimation to turn brown is an inadequate transfer time during the sublimation process. If the dye is not given enough time to sublimate properly onto the material, it may not fully bond with the fibers, leading to a faded or brownish appearance.

Poor Quality Sublimation Blanks or Transfer Paper

The quality of sublimation blanks, such as garments or other printable items, as well as the transfer paper used, can also impact the color result. Low-quality blanks or transfer paper may not be able to handle the heat and pressure required for sublimation, which can cause color deviations and a shift from black to brown.

Environmental Factors

Environmental factors, such as excessive humidity or exposure to sunlight, can also affect the outcome of sublimation prints. High humidity levels can interfere with the sublimation process, resulting in color changes. Likewise, prolonged sun exposure may cause fading or discoloration over time, causing the black dye to appear brownish.
