We want to print team shirts for our daughter's class. The kids have created an artwork on a tablet. I have exported to jpg, and converted to svg using Inkscape trace bitmap function - it worked fine.
Now, when I try to submit the svg to the print shop, I get an error message. The shop requires a minimum thickness of printed areas of 1.5 mm and a minimum distance between printed areas of 2 mm.
Looking at the artwork, there are hundreds of nodes. The trace bitmap function has created closed paths with black fill. The distance of many edges is smaller than 1.5 mm.
Is there any smart way to optmize the path, without manually editing all the nodes? I tried to Outset the path, but this will thicken all lines in general and it does not look good. I'm looking for a dynamic modification, like outset nodes if the distance to the closest parallel edge is less than 1.5 mm.
First I would use Path>Simplify on all the paths, to reduce the node-count. I'd simplify it until the design starts to suffer, then back off one level.
I'd put a line 1.5mm thick into the design as reference. The current design is close on most of the lines.
I'd use outset path on everything, until the majority are thick enough, then use the Tweak tool to thicken the outliers. Then fix the gaps.
