Some personalisations of the covers like Overprint, Custom Stamp or Laser etching need vector graphics (SVG, AI, CDR, EPS) instead of raster images (JPG, PNG, TIFF, GIF). Vector graphics are not sets of pixels with colors assigned to them but rather a description of lines, curves that can be understood by our lasers or machines that make stamps using chemicals. Pretty boring stuff (for most people).
We know that you may not know a lot about vectors and how to prepare a proper file and we have found a super good and free online converter to help you out.
GENERAL RULES OF CONVERSION:
1. Use the biggest JPG you can even for text. The tool below will "trace" all the pixels into curves. The bigger the input file, the more precise the result will be.
2. All gradients will be lost and converted to a single black color.
3. Do not use backgrounds or shadows - they will be interpreted very badly.
Watch out for thin lines. These thinner than 1mm may not adhere to the linen
LASER ETCHING specific:
Since laser actually burns the fabric, please do not use thick lines or large uniform shapes.
