I'll have to figure out a way to fatten it up a bit, I suppose. :p
Edit: Hm… As a bit of an aside, what's the best format to export raster art for these shirts? And are layers acceptable, or should it all be merged together (with a transparent background, or a separate layer that's the same color as the shirt the design goes on)?
Additionally, I don't suppose I could just up the DPI to 600 or something in order to make my one- or two-pixel-thick lines show up when it's printed? :D
If your artwork is already rasterized, increasing the DPI won't make it magically have more pixels. It will just appear to get smaller. The way the raster programs work is they merely create a document with DPI x width(in inches) x height (in inches). So what this means is if you double the DPI, it simply makes the canvas twice the size in both directions. However as raster artwork is created as pixels, not lines/vectors, it doesn't know how to increase each pixel neatly. Your image would simply take up a quarter of the new canvas.
As for formats for export, it depends what you are exporting them for. Make sure you keep a file with all the layers, as if your design does go to print, you will need to submit the file with a layer for each ink colour. However the images submitted for the derby should not have layers and should be a .gif, .jpg or .png.
Personally, Im a big fan of .png as it tends to be less lossy compression. However you cant control the amount of compression applied to your image and as such may sometimes end up over the 500kb limit. Thats when I then turn to the .jpg format as I can choose the .jpg quality it saves as and such control the file size. (The lower the quality, the higher the compression, the smaller the file)
