How to Design Your Custom Phone Cases

Did you know that printing provides customized mobile phone cases? This means you can add the latest Apple phones and Samsung phones to your store (or print a disposable box for yourself!).

This blog post explains why you should consider adding a mobile phone case to your store, and explains how to design your own custom mobile phone case. It also covers the details of the boxes themselves and how they are printed.

Popular smartphone accessories

As the sales of smartphones grow and new innovative products are launched, the sales of mobile phone cases will also increase. According to a survey conducted by Statista in 2017, 79% of smartphone users have their own mobile phones.

A similar NPD survey found that there are 5 major groups buying mobile phone cases

1. Long-lasting protection-these people are looking for a sturdy, high-quality casing to protect their phones

2·Fashion and style-this group of people takes the beauty of the case very seriously

3.Practical fashion-this group also cares about the beauty of the boxes, but they are more sensitive to cost

4.Basic protection-this group has the lowest selectivity; they want a practical case to protect their phones, but they are not particularly picky

5.Technology enthusiasts-these people are smart and passionate about all technological things

For many smartphone users, mobile phone cases are a popular necessity. The motivation for buying suitcases is quite different-some people emphasize practicality and protection, while others are more interested in suitcases that represent their personal style.

More high-end fashion brands such as Louis Vuitton (Louis Vuitton) are delving into the design of mobile phone cases, positioning the mobile phone case as not only a practical technological accessory, but also a fashion statement. With the case, your phone can be easily customized to express your personality.

By printing, you can enter the mobile phone cover market and make mobile phone covers with your own designs. The next part of this article will detail the mobile phone case and printing process for printing, and include tips for creating graphics.

Whether to add more models will depend on the popularity of the phone and customer demand.

The printing provides thin and light boxes made of a mixture of thermoplastic polyurethane (TPU) and polycarbonate (personal computer) plastic. We also offer stylish liquid flash phone cases made of 100% TPU and filled with quicksand heart glitter gold powder or silver.

Printful offers cases that are thin, light, and made of a hybrid Thermoplastic Polyurethane (TPU) and Polycarbonate (PC) plastic. We also offer snazzy Liquid Glitter Phone Cases that are made of 100% TPU and filled with quicksand heart glitter filling in gold, pink, or silver.

They don’t cover the screen, but they’ll protect the back of the phone from scratches. They’re one-piece, solid plastic construction, and the holes and buttons are aligned with the phone’s features.

These cases aren’t shock-proof. So while they may protect your phone from some minor wear and tear, don’t count on them to be indestructible or to prevent serious damage. They are meant mostly for aesthetic purposes.

How are cases printed?

The first step for every phone case order is approving the graphics—if the graphics match our guidelines, the order is sent to print.

Before printing, a trained operator makes sure the printer doesn’t have any lint or dust. A white underbase and colored top coat are then printed simultaneously using UV printing technology. Once the cases are complete, they’re packaged in poly bubble padded mailers and shipped out.

UV printing essentially dries ink through a photochemical reaction. High-intensity ultraviolet lights are used to cure inks, turning them from liquid to solid. UV printing is commonly used to print on materials such as plastic, wood, and metal.

Make use of transparent colors

Contrary to some of Printful’s other products, we can print semi-transparent colors on phone cases. However, there are some extra considerations to keep in mind if you opt for transparent colors.

1. Avoid printing elements that have both opaque and transparent elements

This is because the contrast of solid colors (which are printed with a white underbase) and transparent colors (without a white underbase) is stark. In some cases the end result may look like there are gaps in your design and that colors didn’t print properly. This is especially noticeable with white and lighter tones, so use extra caution with those colors. The best thing to do is to order samples to test how your graphics turn out.

2. Remember that transparent colors are not opaque

When editing transparent colors in Photoshop, it will refer to “opacity.” Transparency and opacity are the inverse of each other—100% transparent is 0% opaque and vice versa. If you have a graphic and you want 25% transparency, on Photoshop it’ll show up as 75% opacity.

3. If you’re not sure—order samples

As always, we recommend ordering samples to make sure the cases come out the way you envisioned. You always want to see a sample of your product before putting it on the market.

Transparent background and sides

You don’t have to fill up the entire space with your design. Blank space in your print file will be clear and you’ll be able to see the phone through the case.

If you’d like to create a graphic where parts of the case are clear, then keep the phone logo, color, and text placement in mind. You’ll be able to see it, so it may affect the way your design looks.

Graphics don’t wrap around the entire case, so the sides will also be see-through. This is great because it gives you a little bit of both worlds—you get to feature your awesome designs, but you don’t completely cover up the design of the phone, either.

Follow print file guidelines

Be sure to follow the guidelines when creating your print files. A print file that doesn’t match our guidelines might not turn out the way you want. These are our must-follow phone case guidelines:

1. Submit PNG or JPEG files with at least 300 DPI

We recommend submitting your files in PNG or JPEG format. To ensure that the design has a transparent background, submit your design in PNG.  Remember, your artwork should measure 2.93”x6.1” with 300 DPI.

2. Set files to sRGB color profile

Make sure your print file is set to the sRGB color profile, sRGB IEC61966-2.1 to be exact. Don’t worry, most editing software have sRGB color profile set as their default.

3. Mind the safe print area

Keep all important graphic elements or text within the safe print area. This means that the most important elements of your graphic should be within the dotted line of a given template; anything outside the safety zone may be cut off.

4. Remember the camera and logo placement

Keep the placement of the case’s camera hole in mind with your design. And if you’re designing a case that’s transparent or doesn’t have a background color, consider where the phone’s logo or text will appear.

5. Remove template guidelines

When using our templates, be sure to delete the guideline layers before exporting your files. If you don’t delete them, they will show up on the print.

If you want to give your customers a better idea of what they’re buying, we advise you to create product mockups using Printful’s product designer tool (mockup generator). All you need to do is drop your design on the selected product, download generated images and upload them to your store.
