Why Vector Graphics Files Are Essential For Achieving High-Quality Results

Updated: May 7

Vector Graphics vs. Raster Images



When it comes to creating artwork for large format printing, understanding the difference between vector graphics and raster images is crucial. If you do not have a vector, we can turn your raster image into a vector with just a little art time. Send your file here: info@racecals.com.


  1. Vector Graphics

    1. Vector graphics are created using mathematical formulas to define shapes, lines, and curves.

    2. They can be scaled up or down (resolution-independent) without losing quality.

    3. Common vector file formats include:

      1. .ai (Adobe Illustrator): Native format for Adobe Illustrator.

      2. .svg (Scalable Vector Graphics): A web-friendly vector format.

      3. .eps (Encapsulated PostScript): Widely used for print design.

      4. .pdf (Portable Document Format): Supports both vector and raster images.

  2. Raster Images

    1. Raster images (also known as bitmap images) are composed of pixels.

    2. They have a fixed resolution (measured in dots per inch or DPI).

    3. Enlarging a raster image can lead to pixelation and loss of quality.

    4. Common raster file formats include:

      1. .jpg (JPEG): Suitable for photographs.

      2. .png (Portable Network Graphics): Supports transparency.

      3. .tif (Tagged Image File Format): High-quality format often used in professional printing.

      4. .heic (High Efficiency Image Format): The default image format for Apple devices.

Why Vector Graphics Matter for Large Format Printing


  1. Scalability

    1. Vector graphics can be scaled infinitely without any loss of quality.

    2. When designing large banners, billboards, or wall-sized graphics, vector files ensure crisp edges and smooth curves.

  2. Editable

    1. Vector graphics can be edited. Because they are made of individual elements that make up the artwork, those elements can be adjusted in order to achieve your desired results.

  3. Resolution Independence

    1. Raster images have a fixed resolution. Usually 300 DPI for print. Web images are much less at 72 DPI.

    2. Vector graphics, on the other hand, are resolution-independent. This means they can be set to any size and will still look sharp.

    3. For large format printing, you want your artwork to look sharp even at close distances.

  4. File Size Efficiency

    1. Vector files are typically smaller in size compared to high-resolution raster images.

    2. This makes them easier to handle and transfer.

  5. Color Consistency

    1. Vector graphics maintain consistent colors across different devices and printing processes.

    2. Raster images may vary in appearance due to color profiles and rendering differences.

  6. Text and Logos

    1. Logos, text, and other elements with sharp edges should always be in vector format.

    2. Vector files ensure that text remains legible and logos stay crisp.

Best Practices for Large Format Printing


  1. Use Vector Graphics Whenever Possible:

    1. Create your artwork in vector-based software like Adobe Illustrator.

    2. Save your final design as a PDF or other vector format.

  2. Avoid Upscaling Raster Images:

    1. If you must use raster images (e.g., photographs), start with the highest resolution available.

    2. Avoid enlarging them significantly to prevent pixelation.

  3. Remember the Viewing Distance:

    1. Consider where your large format print will be displayed.

    2. If it’s viewed from a distance (e.g., a billboard), lower DPI may suffice.

  4. Check with Us:

    1. Do not hesitate to ask questions if you are unclear on any of these points.

    2. If you do not have a vector, Do Not Worry! We can turn your raster image into a vector with just a little art time. Send your file to info@racecals.com for a review.

In summary, vector graphics are your best bet for large format printing. They offer flexibility, quality, and efficiency, ensuring your designs look stunning whether they’re on a massive billboard or a trade show banner. So, next time you’re creating artwork for that grand-scale project, make sure you have a vector.
