La Water Transfer Printing technology or hydro printing It consists of a decoration process applicable to any type of material, regardless of the complexity of its form. The films or designs range from textures in wood, carbon fiber, metals, camouflages to designs with decorative shapes and can be applied to textures such as wood, plastics, metals, glass and ceramics.
The WTP process uses a polyvinyl paper film soluble in water which contains the printed designs that will later be transferred to the piece to be decorated. Once this film is placed in the water, it is dissolved using an activator, which allows the film to be converted into ink, thus being able to position itself on the surface of the water. Previously, The piece to be decorated must have been treated with a wash, sanding, primer and base coat to improve its adherence.
Once the part has been properly treated, it will be ready to be decoratedTherefore, the piece is submerged and the design ink will wrap it, taking advantage of the water pressure. Once the dipping process is finished, the piece must be rinsed with water to clean it and also intensify the adhesion process. Once the piece is dry, it must be applied a layer of protective lacquer to preserve the design on the piece for years and give it shine.
It is one of our premises. There is a super efficient energy system, the water is reused for up to 1.000 processes and the polluting products are separated by filters to be delivered to the dumping and recycling plants as dictated by local and state regulations.
It is an artisan process that involves the use of various materialchosen and therefore it is more expensive than classical paint. However, it gives objects very special finishes, which would be very cumbersome and expensive to achieve using traditional printing methods (heat transfer, airbrushing, screenprinting, etc.) Therefore we can say that it is a relatively inexpensive process.
Mostly it depends on the complexity and size of the object. For example, a tire requires an average working time of one hour (not including waiting times) and a total time of 4 to 48 hours depending on the drying means available.
At the end of each process, staff carefully inspect the work object, especially after varnishing, the inspection of which by means of intense white light and millimeter lenses makes it possible to detect any defect in the object.
The most common defects are: orange peel and dirt or dust. In the case of detecting it, we proceed to repair or repeat the work, as the case may be.
Hydra WTP offers training and materials through which you can perform the service yourself in a very short period of time. Ideally, start with a Professional Kit and plan to purchase a professional hydro printing tank, as well as reserve a date for our training courses.
Yes, our products have a one year warranty. However, after our 7 years of experience, we have not had to solve any durability problem caused by any of our materials or processes. Negligence and inappropriate uses are excluded from it
Hydra WTP provides an instruction manual completely free of charge when placing an order in our activator and foil online store. It is important to read the manual carefully and especially the highlighted parts, as they are usually the reason for the problems that beginners have: excess activator, non-optimized angle, dive speed, etc.
In addition, we put at your disposal our group of where we have more than 300 professionals and amateurs in the hydro-printing sector and which is already the largest hydro-printing community in Spain. The members will help you solve your doubts. Access the group, introduce yourself and participate in the conversations, doubts, etc. that arise daily.
