Laser Prep: Laser Engraving

Laser Prep turns a photo into a file for laser engraving — a vector pattern (SVG) or a raster (PNG) at the exact size in millimetres. Prepare the image on your phone, then open the file in your engraver's software. FIVE STEPS FROM PHOTO TO FILE Photo → shape and size → tone → pattern → export. Each step shows a live preview, so you see the result before the laser touches the material. PATTERNS • Lines — line thickness carries the tone, the classic engraving look • Dots — halftone dots on a hex grid • Diamonds — a crisp grid that reaches full black • Stars — a decorative pattern for light photos Pitch, angle and strength are set with sliders. Shapes never overlap, so LightBurn and other programs fill them correctly. SHAPE AND SIZE IN MM Circle, oval, rectangle or rounded rectangle. Type the size in millimetres or pick a template: coaster Ø100, medallion Ø40, portrait 120×160, keychain 30×50, A5 board. Move and zoom the photo under the mask with your fingers. An optional cut line goes around the item with the offset you choose. The app warns you when the photo resolution is too low for fine detail. TONE BEFORE BURNING Brightness, contrast and gamma, plus invert for dark materials such as slate and anodized metal. White stays untouched, black is burned at full power. EXPORT • SVG — vector, size in mm stored in the file. Black layer — fill engraving, red layer — cut. Opens in LightBurn, xTool Creative Space, Inkscape and other editors. • PNG — raster at 254, 318 or 508 DPI, grayscale or dithered (Floyd–Steinberg, Jarvis). The resolution is stored in the file, so the size on the bed is exact. • .lprep project file — settings and the original photo in one file, to move a project to another phone or keep a backup. Save to any folder on the phone or send the file to your computer. PRIVATE BY DESIGN No account needed. Photos and projects stay on your phone — the app does not send them anywhere. 8 LANGUAGES English, Ukrainian, Polish, Russian, Spanish, German, French and Portuguese. KNOWN LIMITATIONS • The app does not control the engraver yet: send the file to your engraver's software. • Laser power and speed are set in the engraver's software. • Stars render tones up to about 50% — for dark photos choose dots or diamonds.
