I am making something that is supposed to function like a miniature projection slide. So I want to print some black figures (mostly lines and circular dots) with very small dimensions (0.3 mm and smaller) on transparent A4 sheets. I will then inspect the figures using a microscope. In the past, for similar things other people have used a 5080dpi laser printer.
Now my question is: How can I use software and printer technology to get the smallest possible resolution for my printouts?
The printshop I go to says their best printer is the Ricoh pro c7100sx, which I checked has a printing resolution of Max. 1200 x 4800 dpi VCSEL. I am designing my figures in inkscape. However any other software and printer suggestions are welcome too.
More specific questions: When I save my design to pdf, inkscape lets me rasterize the document. Should I do that? And if so, how many dpi should I use for the rasterization? Or is it better to leave the rasterization up to the printer software?
