Resolution for Phone Case Printing Vending Machine
Ideal DPI
Standard for Printing
You want your design to look nice and clear. DPI means “dots per inch.” For the Kexiaozhan Phone Case Printing Vending Machine, 300 dpi is the optimal resolution. Most companies use this number too. It helps your lines look neat and your colors look bright. If you pick a lower DPI, your picture might look fuzzy or blocky.
Tip: Always look at your image resolution before you upload it. Checking first can help you avoid problems later.
Print Size
The size of your picture is important. If you print a phone case, your design should fit the real case size. For example, if your case is 6 inches tall and 3 inches wide, your picture should be 1800 x 900 pixels at 300 dpi. This stops your design from getting stretched or squished.
DPI Setting  | Recommended Use  | Result  | 
|---|---|---|
300 dpi  | Standard phone case printing  | Clear, detailed print  | 
High-end, photorealistic printing  | Ultra-sharp, premium finish  | 
Minimum Requirements
Risks of Low Resolution
If your image is under 300 dpi, the print may not look good. Here are some problems you might see:
Pictures that look fine on screens can print blurry or blocky.
Low-resolution files do not have much detail, so your design can look fuzzy.
Important prints should look great. Low resolution can make you unhappy with the result.
Blurry vs. Sharp
You want your phone case to look special. High resolution gives you:
Pictures that look like photos, with bright colors and sharp lines.
Raised designs that feel cool and add depth.
Better clarity than other ways of printing.
If you use low resolution, your design might not look as good. Thin lines and small words can be hard to see. You can easily tell the difference between blurry and sharp when you hold the finished case.
Feature  | Specification  | Benefit  | 
|---|---|---|
Resolution  | Superior image quality and clarity  | 
Kexiaozhan makes and sells phone case printing vending machines. The company uses high print resolution, so you get great results every time you use the Phone Case Printing Vending Machine.
Why Resolution Matters
Print Quality
Color and Detail
When you print your design, you want every color to pop and every detail to stand out. High resolution makes this possible. At 300 DPI, your artwork keeps its sharpness. You see smooth color transitions and crisp lines. If you use a lower resolution, like 150 DPI or less, your colors may look dull. Details can disappear. Small text or fine lines might blur together.
Tip: Always check your image’s DPI before uploading. This simple step helps you avoid surprises.
Professional Results
You want your phone case to look like it came from a professional shop. High resolution gives you that edge. Your design looks polished and vibrant. People notice the difference right away. If you use a low-resolution image, the print can look pixelated or fuzzy. This can make your case look homemade instead of high-end.
Here’s what can happen with low resolution:
Pixelation: You see tiny squares instead of smooth shapes.
Blurriness: Edges and details lose their sharpness.
Loss of detail: Fine patterns or small text become hard to read.
Final Product
Scaling Issues
When you upload your art to the Phone Case Printing Vending Machine, the system may need to resize your image. If your file is high resolution, it scales up or down without losing quality. If your image is too small, stretching it makes flaws more obvious. You might see jagged lines or blurry spots.
Let’s compare:
Image DPI  | Print Result  | 
|---|---|
300 DPI  | Sharp and clear  | 
150 DPI  | Blurry and pixelated  | 
Edge Clarity
Edges matter a lot on a phone case. You want the borders of your design to look neat. High resolution keeps edges crisp, even around curves and corners. Low resolution can make edges look rough or fuzzy. This is easy to spot, especially when you hold the case in your hand.
High resolution (300 DPI or more) keeps your design looking sharp.
Low resolution (under 150 DPI) often leads to pixelation and blurriness.
If you want your custom phone case to stand out, always choose the highest resolution you can. Your final product will look brighter, sharper, and more professional.
File Types for Phone Case Printing Vending Machine
Choosing the right file type makes a big difference when you print your design. You want your phone case to look sharp and colorful. The Kexiaozhan Phone Case Printing Vending Machine supports several popular formats. Let’s look at the best options for your artwork.
Recommended Formats
PNG
PNG files work well for designs with clear edges and bright colors. You can use PNG if your image needs a transparent background. This format keeps your lines crisp and your colors bold. PNG uses lossless compression, so your image does not lose quality when you save it. Many artists pick PNG for logos, icons, or artwork with sharp details.
JPEG
JPEG is the most common format for photos. You might use JPEG for pictures of people, pets, or scenery. JPEG files are small and easy to upload. They work fast and save space. However, JPEG uses lossy compression, which means some details can disappear. If you print a JPEG, you may notice the image looks softer or less sharp than a PNG or TIFF.
TIFF
TIFF files are the top choice for professional printing. You get the highest image quality with TIFF. This format supports both lossy and lossless compression. TIFF files can be very large, so they take longer to upload. If you want every detail to show up on your phone case, TIFF is a strong option. Many photographers and designers use TIFF for their best work.
Tip: If you want to keep transparency in your design, choose PNG. If you want the best print quality, try TIFF.
Format Pros and Cons
Compression
Compression affects how your image looks and how big the file is. PNG uses lossless compression, so your image stays sharp. JPEG uses lossy compression, which makes the file smaller but can blur details. TIFF can use either type, but most people pick lossless for printing.
Transparency
Transparency lets you create designs without a solid background. PNG supports transparency, so you can make cool effects or floating images. JPEG does not support transparency. TIFF can handle transparency, but not all printers use it.
Here’s a quick table to help you choose:
Format  | Advantages  | Disadvantages  | 
|---|---|---|
PNG  | Preserves image quality, supports transparency, and handles deep colors efficiently  | Larger file size, not preferred for commercial printing due to lack of CMYK support.  | 
JPEG  | Smaller file size, widely used for routine photos  | It can become blurry in printouts, and does not support transparency  | 
TIFF  | Extremely high image quality, supports both lossy and lossless compression  | Large file size, not suitable for everyday marketing content  | 
You want your phone case to look its best. Picking the right file type helps your colors stay true and your details stay sharp. Think about your design and choose the format that fits your needs.
Preparing Your Art Files

Getting your artwork ready for printing is easy when you know what to do. You want your design to look sharp and colorful on your phone case. Let’s walk through the steps for setting resolution and sizing your artwork in popular design programs.
Setting Resolution
Photoshop
You can set up your canvas in Photoshop with just a few clicks. Here’s how you do it:
Open Photoshop and create a new file.
Set the canvas size to 2000 pixels wide and 4000 pixels high.
Choose a resolution of 300 PPI (pixels per inch) or higher.
Pick a color profile like Display P3 for vibrant colors or sRGB for compatibility.
Save your file as PNG, JPEG, or TIFF.
Tip: Always double-check your resolution before you start designing. This helps you avoid blurry prints.
Procreate
Procreate makes it simple to set up your artwork for printing. Follow these steps:
Tap the “+” icon to create a new canvas.
Enter 2000px for width and 4000px for height.
Set the DPI to 300 or higher.
Select a color profile that matches your needs, such as sRGB.
Export your finished design in PNG or JPEG format.
You can find these settings under the “Canvas” menu when you start a new project.
Canva
Canva is great for beginners. You can prepare your art for printing by:
Clicking “Create a design” and choosing “Custom size.”
Enter 2000 x 4000 pixels for your canvas.
Download your finished design as a PNG for the best quality.
Canva sets the resolution automatically, but you should always check the export settings to make sure your file is high quality.
Setting  | Recommendation  | 
|---|---|
Resolution  | |
Color Profile  | Display P3 or sRGB  | 
Sizing Artwork
Templates
You don’t have to guess the right size for your phone case. The Phone Case Printing Vending Machine offers instant personalization with easy-to-use templates. You can pick from an image library or upload your own design. The machine’s advanced AI technology helps you adjust your artwork so it fits perfectly.
Feature/Template Type  | Description  | 
|---|---|
Instant Personalization  | Quickly customize your phone case with various designs  | 
Image Library  | Choose from a wide range of popular designs  | 
Upload Option  | Add your own images for a unique look  | 
Bleed Zones
Bleed zones are important for printing. They make sure your design covers the whole phone case, even the edges. You should extend your artwork slightly beyond the template’s borders. This prevents white lines from showing up on the sides. Most templates show you where the bleed zone is, so you can adjust your design easily.
Note: Always keep important details away from the edges. This way, nothing gets cut off during printing.
With these steps, you can prepare your art files for a professional-looking phone case. The Kexiaozhan Phone Case Printing Vending Machine makes it easy to create designs that show off your style.
Common Mistakes
When you get ready to print your custom phone case, you want your design to look amazing. But sometimes, small mistakes can lead to blurry, pixelated, or dull results. Let’s look at the most common errors and how you can avoid them.
Low-Resolution Images
Web Images
Many people grab images from the internet because it’s quick and easy. Most web images are set at 72 DPI, which works for screens but not for printing. If you use these images, your phone case might look fuzzy or blocky.
Most online images are only 72 DPI.
Images from phones or social media may be compressed and lose quality.
Tip: Always start with the largest, highest-quality image you can find. Avoid using web images for printing.
Spotting Issues
You can spot a low-resolution image before you print. Zoom in on your design. If you see jagged edges or blurry details, your image is too small. When you print a low-res image, you get pixelation—those little squares that make your picture look like a puzzle.
Pixelation happens when you print an image that is too low in resolution. The bigger you print, the more these squares show up.
Resizing Errors
Stretching
Sometimes, you want your design to fill the whole phone case. If you stretch a small image to fit, you lose sharpness. The picture might look warped or fuzzy. Always use an image that matches the size you need.
Cropping
Cropping can help you focus on the best part of your design. But if you crop too much, you might cut out important details or make your image too small for printing. Check your design after cropping to make sure it still looks sharp and complete.
Format Problems
Compression
Saving your file in the wrong format can ruin your print. JPEG files use compression to make the file smaller, but too much compression can blur your image. PNG files keep your lines crisp, but the file size is bigger. TIFF files give you the best quality, but they take up more space.
Transparency
If your design needs a clear background, use PNG or TIFF. JPEG does not support transparency. If you save a transparent design as a JPEG, you’ll get a white or colored box behind your image.
Quick Tips to Avoid Blurry or Pixelated Prints:
Save your design in the right color mode (CMYK for print).
Start with the largest image size possible.
Avoid web images for printing.
Choose the best file type for your design.
Pixelation occurs when you print a low-resolution image. You see blocks of color instead of smooth lines. Always check your image’s DPI before uploading to the Kexiaozhan Phone Case Printing Vending Machine.
