Screen printing on plastic is a great way to bring your designs to life on any plastic material. You can customise your plastic projects with vibrant colours and unique designs. The process is simple and straightforward and can be completed with a few basic supplies. The amazing designs made with screen printing on plastic can make your projects stand out and give them a professional touch.
Let’s take a look at the steps needed to screen print on plastic:
Prepare the Plastic Material
Before printing, make sure your plastic material is clean and free of any foreign objects. This will ensure that your design will be properly printed.
Prepare the Screen
Once your plastic material is ready, it’s time to prepare your screen. Start by using a high-quality emulsion. This is a liquid that remains on the surface of the screen and helps to transfer the design to the material. After applying the emulsion, let it dry and cure completely, this will take several hours depending on the recommended curing time.
Apply the Design
Once the screen is prepared, it’s time to apply your design. Start by printing the design onto a transparency sheet. Then, place the transparency sheet onto the screen and place the screen onto the plastic material. Secure the materials together and make sure there are no wrinkles or bubbles.
Expose the Design
Now it’s time to expose your design. Place the screen assembly under a light source, such as a lightbox or a bright light. Expose the screen for the recommended time, this will vary depending on the type of emulsion used.
Rinse and Dry
Once the design has been exposed, it’s time to wash off the unexposed emulsion. Gently rinse the screen using water and a garden hose or a pressure washer. Then, use a squeegee and a light-duty soap or detergent to wash off the remaining emulsion. Finally, let the screen dry completely before moving on to the next step.
Now it’s time to print the design onto the plastic. Place the screen back onto the plastic and secure it in place. Make sure the strategy is aligned correctly before beginning the printing process. Once everything is in place, use the squeegee to press the ink through the screen and onto the plastic. Move the squeegee back and forth in a single, even stroke.
After printing, removing any excess ink from the screen is important. Use a rubber spatula or scraper to remove the excess ink. Then, gently wipe down the screen with a lint-free cloth.
Cure the Design
The last step is to cure the design. Place the printed plastic material in a dry and well-ventilated area. Then, cure the design according to the recommended time and temperature settings. After the design is cured, your printed design should be permanent and ready to use.
Finally, you have just completed your very own screen printing on plastic. Screen printing is a great way to add designs to plastic materials and with a few simple steps, you can create beautiful, vibrant designs. Now, you will be able to successfully start your next project.
One particular kind of container for storing and dispensing grease is a grease cartridge. The basic design entails a cylindrical tube composed of metal or plastic with a nozzle attached at one end and a threaded cap at the other. In industrial, agricultural, and automotive settings, grease cartridges are frequently used to apply lubricant to machinery and equipment in a clean, simple manner. In order to be conveniently replaced when empty, the cartridges are loaded with a particular kind of grease that is suitable for the purpose.
