When preparing artwork for laser engraving, it’s important to understand the two main types of images: raster vs vector. The type of image you use directly impacts engraving quality, affecting sharpness, detail, and how well the design translates onto different materials. Each format has its strengths and limitations, especially when it comes to scaling and precision.

What Are Raster Images?
A raster image is composed of tiny colored squares called pixels. Common examples include photographs taken with your phone or camera. These images work well at their original size, but when enlarged, they can become blurry and pixelated.
Imagine taking a small photo and enlarging it to the size of a wall mural—you’d start seeing individual square pixels, making the image appear grainy. In laser engraving, this effect can cause fine details to blur, reducing the clarity of the final engraved design, especially on intricate or high-detail projects. A high-resolution raster image can produce great detail, but if the resolution is too low, edges may look jagged or unclear.
Raster Images in Laser Engraving
Laser engravers interpret raster images by turning individual pixels into engraved or non-engraved areas. This means:
- Small, detailed raster images can sometimes lose clarity when engraved.
- Large raster images may reveal pixelation when engraved on bigger surfaces.
- Low-resolution images will not engrave cleanly when stretched beyond their original size.
What Can Be Done?
If your logo or image is low resolution but needs to be engraved at a larger size, we have two options:
- Image Enhancement – We can attempt to sharpen and refine details.
- Vectorization – Converting the image into a vector format for optimal engraving quality.
What Are Vector Images?
Unlike raster images, vector images are created using mathematical paths, allowing them to be resized infinitely without losing quality. Logos, text, and line-based designs are typically created as vector files so they can be scaled up or down without distortion.
Most major brands provide their logos in vector format to ensure they remain sharp on everything from business cards to billboards. For example, companies like Nike, Apple, and Coca-Cola use vector-based logos to maintain clarity and consistency across all marketing materials, whether on a tiny product label or a massive outdoor advertisement. When engraving, a vector file ensures clean, precise lines and no loss of detail—whether the design is being engraved onto a pen or a large metal sign.
Why Vector Images Are Ideal for Engraving
- Sharp, clean lines with no pixelation.
- Scalability – Can be resized to any scale without losing detail.
- Precision engraving, especially for fine details.
If your image is already a vector file (such as an SVG, AI, or EPS format), we can engrave it exactly as designed. If you’re unsure whether your file is a vector, try zooming in—if the edges stay sharp, it’s likely a vector. You can also check the file extension or open it in a design program like Adobe Illustrator or Inkscape. If needed, we can help convert your logo or artwork into a vector format.
Raster vs Vector Engraving – Which One Do You Need?
Not all images can be converted to vector format. Photographs of people, pets, or landscapes will always be raster-based, but they can still be engraved with adjustments.
- Raster images work best for engraving on smooth, non-textured materials like metal, painted surfaces, or acrylic.
- Vector images are ideal for logos, text, and line drawings that need to stay sharp at any size.
