Bitmap and vector are two different types of digital image files. Bitmap is an image type that consist of
numerous square pixels. Bitmap files are rich in details which are mostly suitable for photography or digital applications. However, the quality is related to the resolution so the image can get jagged or blurry when resized. JPG and PNG are two commonly used bitmap format which are both compatible with Beam Studio.
4.2.1 Engraving Resolution
Engraving resolution can be set in Beam Studio by menu > "Edit" > "Document Setting". Engraving
resolution stands for the fineness and quality of the final result. Get more detailed results when the
resolution is set to "High" , but it takes longer to engrave the same file. On the contrary, setting the
resolution to "Low" gets rough quality but takes shorter time. The quality stands for the spacing of each line scanned by the laser which correspond to 0.2mm / 125 dpi, 0.1mm / 250 dpi and 0.05mm / 500 dpi. Select the right resolution to fit the need of the quality and time.
The exposure threshold value can be set when a bitmap image file is imported to Beam Studio. Find
the "Shading" and "Threshold" option in the "Laser Config" label. When "Shading" is disabled, images will
be transformed into monochromic, which is optimized for built-in "Monochromatic Engraving" parameters.
When "Shading" is enabled, images will be transformed into grey-scale, which is optimized for built-in "Shading Engraving" parameters.
The "Threshold" value can be adjusted when “Shading” is disabled. This function is based on the RGB color model which defines colors from 1 to 255. 1 stands for black and 255 stands for white. For example, setting the threshold value to 125 will turn all colors above 125 into white.
