How to Print on Metal: Inkjet Printing and Laser Transfers

Printing on metal can be a challenging but rewarding endeavor, whether you're personalizing gifts or creating artistic pieces. This article will guide you through two popular methods: using an inkjet printer and performing a laser transfer. Follow these steps to create memorable and durable prints on various metal surfaces.

Inkjet Printer Method

One effective way to print on metal is by using an inkjet printer. This method involves several steps, including selecting the right metal sheet, preparing the surface, and printing. Let's dive deeper into each step:

Step 1: Choose the Right Metal Sheet

The first step is to select a thin sheet metal, such as aluminum flashing. Opt for the thinnest metal you can find, as better results come from thinner materials. You can purchase these sheets from online retailers or your local hardware store.

Step 2: Cut the Metal Sheet to Size

Determine the size you want your print to be and use measuring tape and a straightedge to mark the cuts. Utilize tin snips to carefully cut the metal along the marked lines.

Step 3: Sand the Surface

Sanding the surface is crucial as it removes the protective top coat that prevents ink from adhering. Use 600-grit sandpaper, a sander, or a sanding block to smooth the metal. This step may take several passes to ensure a smooth finish.

Step 4: Clean the Metal Sheet

Thoroughly clean the metal sheet to remove any grease or stains. Opt for a commercial cleaner such as Mr. Clean Magic Eraser or a mixture of dish detergent and water. This step ensures the metal will receive a clean, ink-friendly surface.

Step 5: Apply Inkjet Precoat

To help the ink adhere to the metal, apply an inkjet precoat. Apply the precoat in a line across the top edge of the metal sheet and use a straightedge to spread it evenly. This precoat will enhance the ink's adhesion during printing.

Step 6: Attach the Metal Sheet to Paper

Attach the metal sheet to a piece of paper that fits within the printer feed. Use masking tape to secure the edges, ensuring the side you want to print on is facing up.

Step 7: Prepare the Print Job

Prepare your print job on a computer, positioning the image correctly within the document. If the metal sheet is smaller than your printer's feed, adjust the image accordingly.

Step 8: Print Using the Inkjet Printer

Load the attached metal sheet into the printer and print your chosen image. Ensure the metal's coated side is the side that will receive ink. Allow the ink to dry after printing.

Laser Transfer Method

Another method for printing on metal is the laser transfer technique. This method primarily involves laser printing and transferring the image to the metal sheet. Here’s how to do it:

Step 1: Prepare the Metal Sheet

Cut the metal sheet to the desired size using tin snips. Ensure the size matches your intended print dimensions.

Step 2: Print the Design with a Laser Printer

Print your desired image on the metal sheet using a toner-based laser printer. Choose either color or black and white, ensuring the image fits within the metal sheet's dimensions.

Step 3: Sand the Metal Sheet

Remove the protective coating by sanding the metal sheet with 600-grit sandpaper. Use a sander to avoid leaving scratches. Sand multiple times for optimal results.

Step 4: Remove Excess Paper

Carefully cut out the design so there is no paper hanging over the metal edges. If necessary, trim the excess with scissors.

Step 5: Apply Acrylic Polyurethane

Apply a thin layer of acrylic polyurethane over the metal sheet. Use a small paintbrush to apply the coat evenly, ensuring the ink adheres properly.

Step 6: Transfer the Image

Place the design, face down, onto the acrylic polyurethane-covered metal sheet. Slowly lay it out to avoid air bubbles. You can use a rolling pin to apply pressure evenly. Allow the design to stick for one hour.

Step 7: Remove the Paper

Rub the back of the design with a water-soaked paper towel. This step helps remove the paper backing, revealing the printed design on the metal sheet.

Conclusion

Printing on metal requires a bit of effort and attention to detail, but the results are well worth it. Whether you choose the inkjet printer method or the laser transfer technique, these steps will help you achieve professional-looking prints on metal sheets. Happy printing!
