Vector Graphics Resolution Setting: A Guarantee of Laser Engraving Clarity

The resolution of the vector image is a critical factor in the clarity of the laser engraving.The book explains in detail how to adjust vector graphics resolution and optimize design parameters to ensure that the finished laser engraving is clear with no blurring. It also provides solutions to common problems, helping users quickly master the core techniques for improving engraving quality.

Why does resolution affect the quality of the laser engraving?

You may have encountered the following situation: a carefully designed vector graphic, which, after being engraved, has blurry or even broken lines.The problem is usually in the resolution settings.Although a vector graphic can be enlarged indefinitely, if the resolution is too low when the graphic is converted into a path that a laser can recognize, the edges will look jagged.He must find the balance point to achieve both clarity and efficiency.

How can the resolution of vector images be set?

The parameters were adjusted according to the material.

Different materials have different requirements for accuracy.For example, when carving wood, a resolution of 300 DPI or higher will ensure smooth lines. For harder materials such as metal or acrylic, a resolution of 600 DPI is recommended to avoid distortion of small patterns.Before actual production, test strips can be made using scrap material, which saves a lot on trial and error.

Check the export settings in the design software.

Many design programs (such as Adobe Illustrator and CorelDRAW) export vector graphics at resolutions that may not be suitable for engraving.When exporting the file, be sure to manually select "Preserve Original Size" and "High Precision Path Conversion.If you find that the preview of the file in the engraving software is blurry, try switching the units from centimeters to millimeters.

A small trick for optimizing your route.

Too many curves will put a heavy burden on the carving machine's computer.The "simplify path" function reduces the number of nodes, which makes the file smaller and allows the engraving machine to move more smoothly.The thickness of the lines in important areas (such as text or logos) should be kept above 0.1 mm to prevent breaks due to vibration during carving.

Common problems and emergency treatment.

What to do about the lines looking blurred after carving?

First check to see if the original image has any unclosed paths, and then use the magnifying glass mode to see if the points are smooth.If the problem still persists, try increasing the resolution by 1.5 times and re-exporting, and in the software, reduce the speed by 20 %, so that the laser head has more time to dwell on each point.

How do I get rid of the frayed edges?

This is a common problem when resolution and power are not matched.Wooden material can reduce the power (about 10 %) and increase the resolution.Remember to clean the laser lens regularly, as dust can also lead to scattering problems.

Maintenance improves stability.

Don't underestimate the importance of machine calibration! At least once a month, the focus and belt tension should be checked. This is especially important when the thickness of the material being printed changes frequently.After calibration, the effect can be tested with standard test images (such as concentric circles) to ensure that the error on the X and Y axes is no more than 0.05 mm.
