The truth is that almost anything you want to do can be simply done. The trick is to have results that stand out.
Transparent plastic materials are great tools for you to make business presentations and other art materials. All you need is to know how to print on plastic.
The fact is that plastic is a fantastic material due to its unique properties. Let’s have a look at how you can print on it.
What are the various methods of printing on plastic?
There are many ways you can utilize in order to create excellent crafts when printing on plastic.
1. Flexographic printing
This method involves the use of a flexible relief plate. That’s where the name flexo originates. Flexo is a modern letterpress version that can print any substrate.
This can be plastic, paper, or cellophane. Through this method, you can print both images and words on vinyl. You will need to divide the plastic into the non-image and image areas.
To help with the process you will want to wrap the flexible printing plate around a rotating cylinder. The plate is also inked and, therefore, transfers words and images to the printing area of your plastic.
2. UV Litho printing
The UV Litho printing process involves the utilization of UV drying units. These units dry out the ink on the surface of flexible substrates.
This method of printing provides multiple benefits that help you achieve high-definition images.
These images can be in a variety of colors. However, the initial setup process is time-consuming and quite costly as well.
Since these run-ons are a bit fast, it is affordable compared to production runs that take longer.
3. Pad printing
If you are looking for the most simple process to print plastic, then this is what you need.
All you need is to engrave the image you would like to print on a silicone plate. It will then be flooded with ink and then wiped. Ink is left only in the etched area.
This method of printing is incredible, especially for 2-D images printed directly on 3-D objects. Your choices are many, from bottles, rulers, and promotional golf balls, among others.
The most economical printing in this method is a single color pad printing print. It is not limited to a single color because you can print multiple colors, too.
4. Laser printing
This is an electrostatic method of digital printing. With this process, you can achieve top-notch quality graphics and texts.
What you do is pass the laser beam back and forth repeatedly on a cylinder that has been negatively charged.
A standard office laser printer is suitable to use when you want to print on plastic. Just make sure that the materials you are printing are compatible. Otherwise, you run the risk of the fuser unit in the printer getting extremely hot and melting the plastic sheets.
5. Hot stamping
The hot stamping method is a great way to print finished plastic bags. You can pass the bags on a hot stamp machine. This is done one bag at a time and you will achieve perfect results.
This method is suitable for a few plastic bags. If you don’t have ink, then a foil can be substituted to work in its place. With this method, you are limited to using only two colors to print.
Ensure that there is adequate spacing so that there will be easy movement when you are ready to print the next color.
6. Digital Ink-Jet Printing
Nowadays, you have the option to print a digital image or written text on physical media, like plastic. You can achieve this by using a printer, a printer driver, paper, or a spot of liquid ink.
Digital printing is a professional form of printing. This area allows you to print small-run jobs from digital sources using a large format. This printing method needs minimal setup.
This printing process is suitable for short production runs. That means long production runs won’t be cost-effective in the digital inkjet printing arena.
7. Screen printing
Screen printing is a traditional method of printing and is suitable for specific applications. In this method, blocked stencils are used on a soft silk mesh.
With the soft silk mesh, you squeegee ink so that you can transfer the design of the stencil to the substrate. The next step is to use UV light to dry the ink. This process gives you a durable print with bold colors.
