Laser Engraving File Preparation: Vector vs Raster Artwork

Good laser engraving starts before the machine is switched on. Preparing the artwork carefully helps you avoid cropped designs, unexpected filled shapes and wasted material. The first step is knowing whether your design is vector artwork or a raster image.

Vector artwork: paths and outlines

Vector files describe shapes as paths rather than a grid of pixels. They are useful for logos, lettering, line drawings and clean geometric designs. A vector path can be used as an outline or, depending on the software and workflow, as a filled shape. Before engraving, check that text is converted to outlines if the receiving software may not have the same font installed. Also inspect overlapping paths and duplicate lines, which can cause a machine to trace the same area more than once.

Common vector formats include SVG, PDF and AI, but supported formats vary by software and machine. Confirm the accepted file types in the manual for your specific setup. Exporting a PDF does not guarantee that every effect, font or layer will behave as expected.

Raster artwork: pixels and tones

Raster files are made from pixels. Photographs, textured artwork and shaded images are commonly prepared as raster files such as PNG, JPEG or BMP. The quality depends on the image dimensions and how the engraving software converts tones into a mark. A small image enlarged significantly can look soft or jagged. Start with a clear source image, crop it to the material size and preview the result at its intended dimensions.

Set the document up for the material

Before sending a job, set the artwork canvas to match the usable work area and the dimensions of the blank. Keep important details away from the edges. Check units, orientation and scale; a design measured in millimetres can be misread if the project is set to inches. Use the software preview to confirm the placement and direction of the work.

Run a small test before the final piece

Material species, coating, finish and surface condition can all affect the result. Test the design on an offcut from the same material when possible. For a photograph or shaded design, compare a small crop first. Follow the machine maker’s instructions for material compatibility, focus, ventilation and operating settings. Do not assume a setting used on one material is safe or suitable for another.

Pre-flight checklist

• Confirm the file format is supported by your engraving software.
• Check document units, artwork size and orientation.
• Outline fonts where appropriate and inspect paths for duplicates.
• Preview raster images at the final size and crop.
• Test on a matching offcut and follow the machine’s safety guidance.

Choosing a machine is only part of a reliable workflow. Review the C1 Ultra product details and confirm the listed specifications and compatible materials suit your intended projects before ordering.
