I am trying to place some instructions for the operation of controls onto the silkscreen of an unused area of the PCB. The drawing tools in PCB are too simplistic, so I am preparing the design in Inkscape (which uses SVG natively). No matter what format I prepare and import -- I've tried the original SVG, PNG at 300 and 2400dpi, 1-bit BMP at 2400dpi -- it always seems to be autotraced crudely at a low resolution. Screen capture of design (ignore Inkscape's blue grid background; ovals are 170mil / 4.3mm tall):  Screen capture of imported 2400dpi BMP:  Trying to place the actual SVG is, a bit surprisingly, the worst result... almost completely unrecognizable. From this experience, I have two questions: 1) Could someone help me understand how the placed image is being processed, and 2) How can I prepare an image for the most accurate reproduction? Thank you
