Magnetic Signs

Magnetic signs are a low cost alternative to lettering directly on a vehicle. Because a customer can easily put them on and then remove them, they are extremely popular for many small businesses. Over the past decade or so, magnetic signs have become a staple of any modern contractor business and have also become quite popular in all types of other small businesses. They offer two very important ingredients for success: low initial cost and high read rate. Simply put, magnetic signs on each side of your car (and even the back doors or tailgate), printed with your company name, website address, phone number, and a short list of services you offer, create extremely effective and inexpensive mobile advertising that you can use on and off on demand without damaging your vehicle.

Will magnetic signs hold well on my vehicle?

Our car magnets come in a range of sizes that fit almost any car, truck, SUV or work van. Magnetic signs are usually ordered in pairs, so they can be displayed on both sides of your car simply by sticking to the surfaces where you wish to place them. Speaking of surfaces, we should note here that not all metallic surfaces will work. Magnets will not stick to non ferrous metals and alloys including aluminum and stainless steel. There are surfaces that look like they should hold magnets that don’t. For instance, Chevrolet Corvette body parts are made from fiberglass. Other modern vehicles use aluminum door panels to reduce weight. Ultra high-end vehicles might use carbon fiber. You may also have trouble with doors made from plastic composites such as those found on some GM minivans. Therefore we suggest you test your vehicle with any small refrigerator magnet before placing your order with us, just to be safe.

In general, the bodies of some newer sports cars and other high-end car, truck and SUV models can be problematic when it comes to using magnetic signs - but the vast majority of vehicles out there on the road are equipped with ferrous metal doors that our magnets cling to with great reliability.

Magnets are digitally printed in high resolution full color

Primtastic produces magnet signs using a three step process. First, your image is printed onto adhesive vinyl using high-res print process for the best possible image quality. For the second step, we take the printed vinyl and apply an overlaminate to it. The laminate is a visually clear protective film with a nice luster finish. The third and final step is to use a wide format laminator to permanently apply the printed and laminated vinyl to the magnetic backing material.

This process ensures the longest possible product lifespan and provides the best possible image quality when compared to other magnetic sign making processes that use only a single step to print directly onto the magnetic material with no extra protection applied afterward. The lamination that we apply delivers an extra layer of protection from abrasions and chemicals that are found on roadways. Before shipping your vehicle magnets, we round all four corners to safeguard your vehicle against scratches and to prevent “dog earing” which helps keep the magnet mounted to your car by minimizing wind resistance on the corners.

We offer a good selection of most common and popular magnetic sign sizes. As a precise fit is critical for magnets to lay completely flat on your vehicle, with no air pockets, plastic moldings, hard curves or door hinges, etc, we strongly suggest measuring a completely flat surface that will fit your magnets well on your vehicle.

To give you a general idea and a starting point of usable sizes for different vehicle types, we group available magnetic sign sizes into Car, Truck and Van magnets:

We use 30mil thick Magnum Magnetic brand material at about 2 credit cards thick

We use the finest material from Magnum Magnetics to create custom magnetic signs. The magnetic material is the professional grade that is magnetized with 12 poles per inch for absolutely no dead spots throughout the surface area. The high quality of the media ensures that the magnets adhere properly to flat surfaces with no air pockets which causes a poor connection between the magnet and the vehicle’s surface.

The thicker the magnet, the more magnetic property it has. This is critical because the stability of a magnetic sign resides entirely in its pull strength. Pull strength is the magnet’s resistance to lifting. This is measured in pounds per square foot. Our high quality magnetic signs have a measured pull strength of 85 lbs/ft2. This level of strength, which is more than sufficient to resist peeling off of a vehicle door at highway speeds, is found only in 30 mil magnetic sheeting.

Magnetic signs are cut to the ordered size with 1/2-inch rounded corners to prevent “dog earing” which helps to keep the magnet mounted to your car by minimizing wind resistance on the corners.

We manually inspect every single file you upload before printing your magnet signs and will only proceed with your order if it can be printed at absolute 100% stunning quality with no compromises.
