By : Admin 8th August, 2024

Many photographers, graphic designers, and embroidery designers need help with image quality. The trouble is that some of these images are pixelated, blurry, and lose their crispness when resized. 

Vector conversion is the only solution. This process converts small or blurry pictures into larger, clear ones. It's a file format conversion process that removes pixelation and converts a raster image (made of tiny squares) into a vector form (made of lines and shapes). 

Unlike raster images, vector graphics can be scaled infinitely without sacrificing sharpness, making them ideal for logos, illustrations, and large-scale printing.

Now you might be wondering how you can convert raster to vector. This blog will tell you all about raster to vector conversion. So, keep reading if you want to eliminate blurry images forever.

Raster vs. Vector Images

When it comes to digitizing embroidery, your image's format plays a crucial role in achieving stunning results. Here's the detail of the two main image types and how they impact your embroidery journey:

Raster Images:

These images are composed of a grid of tiny squares called pixels. These images lose quality when enlarged, resulting in a blurry or pixelated appearance. Raster image file format is commonly used for photographs, digital scans, and everyday graphics. However, they have a critical limitation for embroidery – they lose quality when resized. The edges become blurry and jagged, compromising the detail of your embroidery. 

Common Raster File Formats:

  • JPEG (Joint Photographic Experts Group)
  • PNG (Portable Network Graphic)
  • BMP (Bitmap Image File)

Vector Images

Unlike their pixelated counterparts, vector images represent artwork using mathematical paths that define lines, shapes, and curves. They are like a drawing instruction manual for your embroidery machine

They have infinite scalability – you can resize them to any size without losing detail. This ensures clean, well-defined, and smooth stitches regardless of the design's final size on fabric.

Common Vector File Formats:

  • SVG (Scalable Vector Graphics)
  • AI (Adobe Illustrator Artwork)
  • EPS (Encapsulated PostScript)

Advantages of Raster to Vector Conversion

Here are some reasons to convert raster images to vectors:

  • Scalability: Vector graphics can be resized infinitely without losing the detail. They are perfect for logos, illustrations, and graphics used across various platforms.
  • Sharper Images: Vector graphics, with their precise lines and shapes, produce sharp and crisp visuals, for intricate designs, logos, and illustrations.
  • Compact File Sizes: Vector files are typically smaller than raster equivalents. It makes them easier to store, share, and load faster on websites.
  • Editing Flexibility: Vector files allow you to easily modify colors, adjust shapes, and refine your design even after conversion. This allows you to achieve the perfect look for your embroidered creation.
  • Versatility: Vector files can be exported to various formats like SVG, AI, PDF, and EPS. They are compatible with diverse design software and applications.
  • Crisp and Clean Stitches: Vector artwork gives a smooth, well-defined more efficient stitch pattern for your embroidery. This can lead to faster stitching.
  • Time Efficiency: While vector tracing demands precision initially, it saves time by reducing constant adjustments during resizing.
  • Professional Logo Maintenance: Vector tracing preserves vector logo conversion integrity. It can adapt to various marketing materials without quality loss.

Raster to Vector Conversion Method

Here are various raster-to-vector conversion methods to get your raster image ready for embroidery:

Manual Conversion of Raster Images to Vector 

For experienced users or those seeking the highest quality vector artwork, manual conversion in design software like Adobe Illustrator or Inkscape offers the most control. This involves tracing the outlines of your raster image with precise paths using the pen tool. While time-consuming, it delivers the highest quality vector artwork for embroidery digitizing

Here's the stepwise process of the manual conversion process:

Step 1. Open your chosen design software (e.g., Adobe Illustrator) and import your raster image.

Step 2. Create a new layer on top of your raster image for tracing. This helps maintain a clear separation between the original image and your vector artwork.

Step 3. You can reduce the opacity of your raster image to make tracing easier. This allows you to see the underlying layer while creating vector paths.

Step 4. Use the pen tool to trace the image outlines. The pen tool helps you to create smooth curves and sharp corners for accurate embroidery conversion.

Step 5. Once you've traced the outlines, ensure all paths are closed for proper stitching. You can also use editing tools to refine anchor points and smooth out any rough edges.

Step 6. If your design requires filled areas, use the fill tool to apply colors or gradients.

Step 7. Consider simplifying intricate details in your design for cleaner stitching. This might involve reducing the number of color variations or eliminating small elements.

Step 8. Once satisfied with your vector artwork, save it in a format compatible with your embroidery software, such as SVG, AI, or EPS.

Automatic Conversion Methods

Several online tools and software programs offer automated conversion with varying degrees of accuracy. 

Embroidery Software's Built-in Conversion Tools: 

Many embroidery software programs, like Brother PE-Design or BERNINA Embroidery Software, have basic automated conversion tools. These tools can handle simple images with clear outlines, such as logos or text-based designs. They are a good starting point for beginners or quick conversions. 

However, for designs with complex details, shadows, or gradients, you might need to invest some time in manual cleanup for optimal results. This cleanup can involve removing unwanted elements, smoothing out rough edges, or separating overlapping objects.

Online Raster to Vector Conversion: 

Several online conversion tools like Vectorizer.io or Vector Magic (with limitations in the free version) provide automated conversion options. These are convenient for quick conversions of simple designs. 

The quality of the output can vary depending on the complexity of the image. These converted files might require additional adjustments to achieve clean lines suitable for stitching for embroidery designs. You have minimal control over the conversion process, which can affect the final quality of the vector artwork. There's a chance of errors creeping in during the automated conversion, requiring further editing.

Factors to Consider When Choosing a Method

With various conversion options available, how do you choose the right one? Here are factors to consider:

  1. Complexity of Your Design:

Online conversion or your embroidery software's built-in tools are suitable for logos, bold text, or images with clear outlines. These methods can handle basic shapes effectively. Manual conversion in embroidery software is the way to go for designs with fine details, gradients, or complex shapes.

  1. Desired Level of Control:

Online and built-in software tools offer convenience but limit your control over the conversion process. The final output might require further adjustments for embroidery. Manual conversion in design software allows you to control every aspect of the vector artwork. You can refine lines, adjust shapes, and ensure clean paths for optimal stitching results.

  1. Time Commitment:

Built-in tools are the fastest options, ideal for simple designs or when time is a constraint. Manual conversion takes more time but delivers the highest quality vector artwork, perfect for professional embroidery projects.

  1. Software Availability and Skills:

Built-in software tools are user-friendly, even for those with limited design experience. Manual conversion requires design software like Adobe Illustrator and some familiarity with vector editing tools like the pen tool.
