What is a good dpi for laser engraving?

Depending on the amount of detail that your graphic file has, we recommend increasing the image resolution to 600 dpi to allow for the very fine details to be optimally engraved.

How do you focus a laser for engraving?

You can adjust focus spot distance from the front of the engraving laser by rotating the lens clockwise or counterclockwise. Note: it is necessary to ensure that the mounted lens is sufficiently deep inside the laser head, so the lens does not move before powering on the unit.

What is DPI in engraving?

DPI is dots per inch. It tells how many pixels or dots are within every inch of an image, which tells us the resolution of the image. Scan gap is the spacing between lines when scanning to engrave an image. A scan gap of . 1 mm would correspond to a DPI of 254.

What is laser engraving format?

For laser engraving acceptable file formats include the following: TIFF, BMP, JPG or other Raster images that are 1-Bit black and white camera ready artwork.

What is PPI in laser engraving?

PPI and Hz parameters The PPI parameter (=pulses per inch) determines how many laser pulses per inch are used for the engraving. To achieve a good result, this should be the same or a multiple of the dpi selected in the print setting.

How do you increase engraving speed?

4 Ways to Increase Laser Engraving Resolution

  1. Start with a High-Quality Image.
  2. Set Your Laser’s DPI According to the Project.
  3. Choose Speed and Power Settings to Support Resolution.
  4. Test Your Engraving to Check Settings.

How do you adjust the focus on a laser?

If you want to make the focus be at the work piece then just adjust the Z axis down by the thickness of the material you were using. Then, just measure whatever you want to engrave and adjust back up by this thickness to be sure you are at the top of the material before processing.

What is the best file format for engraving?

BMP – a bitmap file is used for engraving only (such as scanned pictures, photographs etc. DXF – this popular vector file can be used for cutting and engraving. AI – this vector file format can be used for cutting and engraving.

What is laser frequency setting?

It specifies the number of laser pulses per second. For a CO2 laser, the value can be set within a range of 1,000 to 60,000 Hz. For example, if you want to achieve a smooth edge when cutting acrylic, you need higher temperatures and thus this value is set to at least 5,000 to 20,000 Hz.

How does frequency affect a laser?

Changing the pulse frequency affects the number of laser pulses striking the part at any location and the amount of laser energy in each of those pulses. Lower pulse frequencies tend to vaporize material because of the higher energy content of each pulse.
