Pick a mode at the top. Load a picture into it. Move the bars until it looks right. Print.
The four modes
StencilTurns a photo or drawing into a clean line stencil, the way a tattoo artist preps a design. Start here for most jobs.
TraceTurns the stencil into vector lines you can scale or cut. Good for logos, lettering, anything that will be resized.
Cut-OutSplits a picture into a few sheets you cut and paint one at a time, lightest first, for spray stencils.
Screen printSplits a picture into ink colours, each on its own film, for printing on fabric. Fewer screens is cheaper.
Stencil
DetailHow fine a line the engine looks for. Low keeps only the strong lines, high finds the hairlines too.
LiftPulls faint tone up into view. Use it when light areas of the picture are being lost.
StrengthHow black the lines print. Raise it if the stencil comes out grey.
WeightMakes the lines that are already there heavier. It never finds new lines and never removes any; leave it at 0 unless the lines are too thin to transfer.
Pencil, Rubber, ChiselDraw a missing line, rub out a stray mark, or use the chisel nib to cut cleanly into a corner. Chisel works with both the pencil and the rubber.
NibHow big the pencil and rubber are.
TrackHow closely a stroke follows your hand. 0 draws a straight ruler line, 100 follows every wobble but smooths it. At 100, draw a rough circle and hold still for two seconds and it becomes a perfect one.
Trace
Fill solidsStops the inside of a thick black shape from producing extra lines. Raise it if you see line work inside solid areas.
SmoothHow closely the curves follow the ink. Sharp corners stay sharp at every setting; only the curves change.
On edge, Inside, OutsideWhere the drawn line sits on the shape. Inside is what you want if you are cutting to the line.
Cut-Out
SheetsHow many layers to cut. Two or three is enough for most stencils. Paint the first sheet, let it dry, then the next.
WhitesAdds a last sheet for the bright highlights, painted white on top at the end.
Lasso and WandKeep or cut a part of the picture. Lasso draws a loop around it, Wand picks it by colour.
CrossesThe small marks in the corners line the sheets up on top of each other. They are switched on and off from the print page, not with the rubber.
Screen print
ScreensThe total number of screens you will burn, including the white base. Four is a sensible starting point; every extra screen costs money.
Drop backRemoves the background around the design. It works inward from the edges of the picture, so detail inside the design is never touched.
HighlightA last white screen for the brightest highlights, only on dark garments. The bar sets how far down the tones it reaches.
Composite, All filmsComposite shows all the screens printed together on the garment. All films shows each screen on its own so you can check them before burning.
Printing and saving
Print and sizeChoose paper, print size and pages. What you see on the print page is exactly what comes out. On iPad or phone the print button opens the share sheet, where you can also save a PDF.
Save PNGSaves the canvas as an image. On iPad or phone it goes to your downloads or Photos. Use this if you want to send the stencil to a print shop.
MirrorFlips the print. Use it for transfer paper or films printed emulsion side down.
