Hydrographic Printing

General Information

Hydrographic printing is a technique that allows objects to be decorated with logos, images, or graphics by transferring the design from a film to the product through water immersion. The process begins with the preparation of the item, which is cleaned to ensure proper adhesion of the decoration. A PVA (polyvinyl alcohol) hydrographic film is then used, onto which the design is printed. This film is designed to dissolve in water, leaving the artwork floating on the surface. A temperature-controlled water tank is prepared to accommodate the product. The film is placed on the water surface so it can float, and a chemical activator is sprayed over it. Its purpose is to dissolve the film support, leaving only the ink on the water. At this point, the item is immersed at a precise angle, allowing the design to adhere to the object. This method makes it possible to achieve decorations on irregular surfaces. After immersion, the product is removed and rinsed to eliminate film residues. Finally, a protective coating is applied to seal the design and ensure long-lasting durability. Hydrographic printing is used to decorate metal, plastic, and wooden items. It is appreciated for its ability to create detailed and long-lasting decorations.

Main Features

✅ Advantages

High graphic quality with accurate details and faithful colors
Unlimited number of colors, including gradients
Excellent results on irregular shapes
Glossy finish and professional appearance
The protective coating increases durability and resistance
Compatible with various materials: plastic, metal, wood, ceramic, and glass

❌ Disadvantages

Longer production times compared to other techniques

Customization and Production Times

Hydrographic printing is a versatile technique suitable for different materials and products with irregular shapes. It allows decoration on plastic, metal, wood, glass, and ceramic. This printing method supports full-color production, gradients, and complex details, ensuring a uniform and visually impactful result. Due to the large number of steps involved, production times are longer compared to other technologies.

Colors and Materials

Hydrographic printing is applied to rigid materials and products with irregular shapes. This technology allows decoration on plastic, metal, wood, glass, and ceramic. It is therefore ideal for bottles, cups, mugs, flasks, thermoses, keychains, and many other uniquely shaped items. Graphics can be produced in full color, with gradients and complex details, ensuring a visually striking result.

Maximum Number of Colors

It is a full-color printing technique with no limits in graphic rendering. Gradients, small details, and complex designs are reproduced with precision, ensuring a sharp and uniform result.

Equipment and Support Materials

The materials and process involved in hydrographic printing are complex. This technique guarantees precise results but requires longer processing times compared to standard solutions. The procedure involves the use of tanks, water-soluble films, drying phases, and supports for positioning the graphics. It is therefore a less accessible option from an economic standpoint.

Printing Cost and Customization

Hydrographic printing is more expensive than standard printing techniques. Although less accessible economically, it offers superior resistance and very high photographic quality. Production speed is slow, with extended times required for both the process setup and drying phases.

Products Suitable for Hydrographic Printing

This high-quality and versatile printing technique is ideal for a wide range of products. Among the most popular are bottles, mugs, cups, flasks, thermoses, rigid keychains, and many other gadgets.

Warnings

Although hydrographic printing is versatile, resistant, and high-quality, some warnings apply. Not all materials are compatible with this technology. It requires controlled conditions, specific materials, and proper handling of supports. Warnings mainly concern alignment and long production times.
