DPI is a unit of measurement in dot matrix digital image, indicating the number of image pixels per inch. The setting range is [1, 1270]. When converted into linear density (lines per cm), 100 linear density equals 254 DPI. A higher DPI theoretically yields a finer engraving image effect.

DPI function is only available for Bitmap Engrave with xTool F1 and F1 Ultra.

When fine engraving is required, such as engraving photographs or complex designs, the higher DPI ensures that the details of the image are fully realized.

When creating company logos, trademarks, and other images that require high resolution, adjusting the DPI can ensure the clarity and professionalism of the logo.

When creating artwork, artists can adjust the DPI to control the detail and texture of the work.

You can select DPI values in two ways:

1. Move the progress bar.

2. Click on the DPI value and change it directly to your desired data.

The original pixel distribution of the bitmap image should be considered when selecting the DPI. When the DPI surpasses the bitmap's pixel distribution, overly dense dots can have a counterproductive effect, causing darker materials to appear whiter (shows in the image below ).

When setting a high DPI, be sure to consider power matching to avoid overheating or poor engraving.

Different materials respond differently to the laser and may require different DPI settings to achieve optimal results.

When engraving dark-colored materials, too high a DPI can cause the material to overheat, resulting in White spot lesions and increased processing time.

When engraving larger images, the DPI can be appropriately reduced to minimize processing time while maintaining image clarity.
