I get a kick out of taking simple spider web clipart and making it behave like pro-level print art. First thing I do is check whether the file is vector or raster. If it's vector (SVG, EPS, AI), bliss — I open it in 'Illustrator' or a free tool like Inkscape, clean up stray nodes with the node tool, simplify paths so there aren’t hundreds of unnecessary points, and make sure strokes are converted to outlines (Object > Expand or Stroke to Path). That step prevents hairline strokes from disappearing or printing inconsistently. I also union overlapping pieces with Pathfinder so the printer sees a single shape, which is especially helpful for foil, emboss, or die cuts.
Next I set color and output: convert artwork to CMYK, avoid tiny single-color strokes (keep at least 0.25–0.5 pt hairline equivalent depending on printer), and add 3mm bleed around the art. If the design will be screen printed or spot-varnished, I separate spot colors or make a separate black-only stencil. Raster effects (glows, textures) should be at
300 ppi at final size; if you scale up later you’ll lose detail. Finally I export as PDF/X-1a or high-quality PDF with fonts outlined, or save a print-ready SVG/EPS if the shop accepts it. I love seeing the crisp lines
come out perfect on paper — it feels like magic when vector work prints cleanly.
