Water Transfer Printing Equipment Essentials


Have you ever wondered how those intricate designs and patterns are applied to objects like car dashboards, motorcycle helmets, or even phone cases? The answer lies in a fascinating technique called Water Transfer Printing (WTP). This process allows you to transfer intricate designs onto three-dimensional objects, creating stunning visual effects. To achieve such remarkable results, you need the right equipment and tools. In this article, we will explore the essential equipment needed for Water Transfer Printing.

Understanding Water Transfer Printing

Water Transfer Printing, also known as hydrographics or hydro dipping, is a method of transferring intricate designs from a specialized film onto various objects. The process involves water, a transfer film, and a clear coat to protect and seal the transferred design. It is widely used in various industries, including automotive, sporting goods, electronics, and more.

To achieve successful Water Transfer Printing, it is crucial to have the right equipment. Let's dive into the essential tools and machinery needed for this remarkable process.

The Water Tank

The water tank plays a vital role in the Water Transfer Printing process. It is a large container filled with clean water, usually made from stainless steel. The tank's size will depend on the dimensions of the objects you plan to dip.

The tank needs to be equipped with a heating element to maintain the water temperature at a specific level. This is important as different films require different water temperatures for optimal image transfer. The heating system ensures that the water remains consistent throughout the entire process.

Additionally, the water tank should have agitators or circulating pumps. These devices help to keep the film in motion, preventing it from sticking to the object being dipped. The continuous movement of the film ensures an even and smooth transfer of the design onto the object's surface.

Spray Guns and Activators

Spray guns are essential in the Water Transfer Printing process. There are different types of spray guns available, such as HVLP (High Volume Low Pressure) guns and airbrushes. HVLP guns are commonly used due to their ability to atomize the paint and deliver a controlled spray pattern.

Activators are crucial for activating the transfer film's ink, allowing it to dissolve in the water and cling to the object's surface. They come in various formulations, each suitable for different types of films and designs. Selecting the right activator is important to achieve a successful transfer and vibrant colors.

It is recommended to have a selection of spray guns and activators to accommodate different film types and object sizes. This allows for greater versatility and ensures optimal results across various projects.

Preparation and Primer

Before the Water Transfer Printing process, adequate preparation is necessary. This includes cleaning and priming the object's surface to ensure maximum adhesion and durability of the transferred design.

A thorough cleaning is crucial to remove any dust, dirt, or grease from the object. This can be done using a variety of cleaning solutions and tools, such as degreasers, lint-free cloths, and brushes. Once the surface is clean, applying a primer is recommended. Primers create a smooth and uniform base for the transfer film, promoting better adhesion and enhancing the final results.

The choice of primer will depend on the material of the object. There are specific primers available for plastics, metals, and other materials commonly used in Water Transfer Printing. Make sure to select the appropriate primer for optimal results.

Transfer Films

Transfer films are the heart of the Water Transfer Printing process. These films come in a wide variety of designs, patterns, and finishes, allowing you to achieve virtually any look you desire. From carbon fiber and wood grain to camouflage and abstract designs, the options are endless.

When selecting transfer films, consider the size and shape of the objects you plan to dip. Some films may be suitable for smaller items like phone cases, while others are better suited for larger objects such as car parts. It is essential to choose films that are compatible with your equipment and can accommodate the desired object size.

Film quality is also crucial in achieving excellent results. Look for films that are stretchable, tear-resistant, and provide vibrant colors. High-quality films will ensure the transferred design is sharp, durable, and visually appealing.

Clear Coat and Finishing

The final essential component of Water Transfer Printing is the clear coat. After the transfer film has been applied and dried, a clear coat is necessary to protect and seal the design. The clear coat adds a layer of durability, making the transferred design resistant to scratches, UV rays, and other environmental factors.

Depending on the desired finish, there are different types of clear coats available. Glossy clear coats provide a shiny and reflective finish, while matte clear coats offer a more subtle and non-reflective appearance. Some clear coats also provide additional features, such as high resistance to chemicals or abrasion.

It is crucial to select a clear coat that is compatible with the type of ink used in the transfer film. Improper compatibility may lead to color bleeding or other undesirable effects. Testing clear coats before actual application is recommended to ensure desired outcomes.


Water Transfer Printing is a captivating process that allows you to transform ordinary objects into extraordinary works of art. To achieve stunning results, having the right equipment is essential. The water tank, spray guns, activators, preparation tools, transfer films, and clear coats are all vital components of a successful Water Transfer Printing setup.

Remember to choose equipment that suits your specific needs, taking into consideration the size and type of objects you plan to dip. By investing in quality equipment and mastering the techniques involved, you can unlock endless creative possibilities and create truly remarkable pieces through Water Transfer Printing. So, dive into this mesmerizing world of hydrographics, and let your creativity flourish!
