Print Prep guide
Clean your artwork
Open, drop or paste a raster image. The wand removes pixels matching a sampled background. Adjust tolerance and soft edges; Contiguous limits the operation to the connected region. Clean color fringe reduces background halos around partially transparent edges.
Use erase, feather, restore and color picker tools from the left rail. Polygon, curve and ellipse masks protect regions from erasing. Switch the preview between checker, white, black and gray to inspect edges. These backgrounds are previews and do not become part of the export. Undo and redo reverse edits. The ? button lists keyboard and mouse controls.
Export
Export transparent PNG for a single image, or three/four spot inks or CMYK for a ZIP containing black-positive transparent plates and a print-job manifest. Spot ink swatches can be edited. Choose output scale and DPI. Print-quality scaling uses alpha-aware, linear-light Lanczos 3. Color inversion preserves transparency; registration marks add matching targets outside each plate.
CMYK plates are continuous-tone separations. Your printer or RIP must apply appropriate halftones. Confirm ink colors, trapping/choke, mesh, emulsion direction and substrate profile with your printer. The tool does not apply a calibrated device ICC profile.
Privacy and saving
Images are processed locally with no account, uploads or analytics on this tool. Artwork is held in memory; there is no persistent draft or project file. Download an export before leaving. Exported PNGs retain the current artwork, but not editable masks or undo history. Opening another image replaces the current workspace. Large images and high scaling factors can exceed browser memory. A download request clears the editor’s unsaved marker; confirm your download was retained.
