Applying the Print to the Metal
Once the design has been prepared and the metal surface has been properly prepared, it’s time to apply the print to the metal. This can be done using a variety of methods, including screen printing, sublimation printing, and laser engraving. Here is a brief overview of each method:
Screen Printing
Screen printing is a type of printing that uses a stencil to create an image on the metal surface. The stencil is created by blocking out the areas of the design that should not be printed, and then the ink is applied through the stencil using a squeegee. Screen printing is a relatively simple and inexpensive process, and it can be used to create high-quality prints with vibrant colors. However, it is not suitable for printing complex designs or photographs.
Sublimation Printing
Sublimation printing is a type of printing that uses heat to transfer an image from paper to metal. The image is first printed onto a special paper using a sublimation printer, and then the paper is placed on the metal surface and heated. The heat causes the ink to turn into a gas and bond with the metal surface. Sublimation printing is a great way to create full-color prints with high detail, and it is also suitable for printing complex designs and photographs. However, it can be more expensive than other printing methods.
Laser Engraving
Laser engraving is a type of printing that uses a laser to engrave an image into the metal surface. The laser beam is computer-controlled, and it can be used to create very precise and detailed engravings. Laser engraving is a permanent process, and it can be used to create a variety of different looks, from simple text and логотипы to complex designs. However, it can be more expensive than other printing methods.
The best method for printing on metal depends on the specific requirements of the project.
