Rattle your brain around and recall the Periodic Table of Elements from your high school Chemistry class days. The Periodic Table contains 94 different metals. Today, we’re going to explore a small portion of that when it comes to UV printing on metals. Many industries rely on parts manufactured out of metal, as well as the expanding field of drinkware relying on stainless steel vessels. The demand for printing on metal for signs, tools, machined parts, metal housing cases, and drinkware is continually rising. Luckily, Inkcups has a complete solution for UV printing on metals whether it be by UV flatbed printer or cylindrical inkjet printing machine.
Some metals, like stainless steel require pre-treatment for optimal adhesion. Stainless steel is one of the most used metals used today for drinkware and promotional products, followed by aluminum. The recommended practice for stainless steel is flame pre-treatment followed by a primer wipe.
Flame pre-treatment increases the surface energy of the substrate. Optimal adhesion is achieved when the surface of the vessel has a higher surface energy than that of the ink tension.
A wipe on primer is the most basic form of pre-treatment, with the operator manually wiping a lint-free towel loaded with primer onto a vessel. For stainless steel, we recommend loading the towel with GB primer, ensuring that your product will pass the scratch, tape and wash tests. The GB primer is a great option for stainless steel as well as various coated metals.
Pre-treatment and the correct choice of ink should be considered as a dynamic duo for superior abrasion resistance. Like pre-treatment, ink is specific to the material of substrate. After flame and primer wipe, decorate your stainless steel product with S1 UV inkjet ink for wear resistant, high resolution print results. The S1 ink line is made up of Cyan, Magenta, Yellow, Black, White and Varnish to achieve full color graphics on metal products, suitable for industrial industries and drinkware companies alike.
Metal substrates are a tricky surface to print on. However, Inkcups has an option to ease the journey each step of the way.
