Sheetcraft is for small-batch label designers preparing short-run print sheets. The recurring job sounds simple until physical tolerances start collecting bodies: place one finished label across a stock sheet, preserve margins and gutters, extend artwork through bleed, add cut guides, and hand the result to Inkscape without inventing dimensions along the way.
The usual workaround is manual duplication in Illustrator plus calculator arithmetic for rows and columns. Change the stock, label size, bleed, or printer margin and the sheet gets rebuilt. Clipping and cut-line mistakes hide in that repetition.
Sheetcraft calculates the maximum valid imposition, rotates the label when useful, reports fit and waste, and constructs separate artwork, bleed, and cut-guide layers. Bleed, gutter, and stock-margin controls each alter the canonical Harbor Tonic sheet independently. The exported document uses physical millimetre dimensions and round-trips into the editor.

The preview and export come from the same authored transformation. The release verifier runs the canonical workflow against the live app, writes fresh SVG bytes, and reruns the committed validator. A pretty grid with fake geometry does not pass.
