Does humidity affect sublimation?

If moisture presents in either the substrate or the transfer paper it can have an adverse effect on the sublimation process. Common problems include color shifting (where colors lose accuracy), bleeding of the image, and uneven transfer of solid filled areas of a design.
The first step in minimizing the effects of humidity is to always store your transfer paper in a dry place. If dealing with poly-performance apparel you can pre-press the shirt for about five seconds if you suspect there may be moisture in the fabric. For other substrates, you can “warm” them on the heat  press without closing it.

However, an environment that is too dry isn't any good either as it can cause print head nozzle loss issues. For best results, check the recommended ranges of humidity for your equipment, then purchase a hygrometer to measure your environment. If adjustments are needed, you can purchase either a humidifier or de-humidifer.

B lotches and spots in your transfers can happen   at any time  and anywhere . T his is a problem generally caused by excess moisture in the environment or on the substrat e. Left : Perfect transfer result.  Right : Blotches and spots in a poor paper Common   sublimation materials like polyester fabric, hardboard, plastic and even metal materials like aluminum and stainless steel can  be sublimated, and w hat happens when there is moisture on a substrate? When water is heated ,  it turns into steam vapor which starts to escape upward , however, since dye-sublimation ink also turns into a gas, the steam vapor from the areas that have even the smallest amounts of moisture clash with the sublimation gas which will  prevent a full and consistent transfer . So how to resolve this blotchy results ? The quick solution is to pre-press substrates immediately before applying & heat pressing the sublimation transfer. Pre-pressing is done by placing the item in the heat press, coverin

Almost daily we receive queries such as: "In my sublimations white dots appear," "When sublimate colored spots appear", "Why leave when sublimate colored dots?". It is a fairly common problem in this post will look at the possible causes and how we can implement a solution.

The sublimation is a fantastic technique customization that allows you to create personalized gifts with maximum image quality a fantastic finish and all with a minimum investment .

Clearly you can stamp your shirts sublimation printer but have to be of polyester and white or light colored .  Sublimation takes place in two steps : First you have to print your design on   sublimation paper  using your sublimation printer equipped with dye sublimation ink  secondly you have to apply heat and pressure with a heat press machine to transfer the design from paper to sublimable shirt or object. It is in this second step wherein sublimation, that is the chemical process in which heat and pressure deposited on the printed paper, inks become gas and actually takes place penetrate the polyester fiber . Therefore, to sublimate a f
