![]() Using these tiny sizes does get pretty low res. This leads me to the conclusion that in Windows, my screen resolution might be contributing if it alters the Pixels Resolution which is defining rather directly, my possible pin spacings on the printout.Īlso, this in kinda the point. There are no options to decide what Kicad sends or not. Of Course I expected these to be just screen visual defects but they actually transfer to the printout. When you zoom in on the PCB everything is not only aligned but using the exact same Widths and ‘Snapped to’ each other. The only other Output Image Kicad produced in the context of what Ive been talking out is PDF with Plot. There are no special options available in Kicad. UM…Print? Kicad? Its what Ive been talking out. So it looks like KiCad gives the vectors to the printer driver, and the printer driver rasterizes it’s input if needed. My printer driver (On Linux) also has a “Print to File” option, and it can save print jobs in either. I don’t know what your “Blurring” looks like. Your printer driver may have (and very likely has) it’s own scaling settings. KiCad has this function built in, but when you click on Print it sends the data to your printer driver, and that is dependent on your OS. If inaccuracies are over 2% then it’s likely some software setting, such as a “Fit to page” function. If inaccuracies are less then 1% then it likely is your printer hardware. With: Pcbnew / File / Print you generate raster output which is send directly to the printer, and with Pcbnew / File / Plot you can generate vector output in a bunch of different formats and save them to files to be printed (or post processed, etc) with other programs.Ĭonsumer level printers are not designed for very accurate output. I’m guessing that by “artwork” you are referring to the PCB. I do have a (cheap laser) printer, but I don’t use it much. This is quite accurate for a £40 printer.ĭoes Kicad produce the print result Via the printer driver or does it handle things its own way and then pass it off? So my printer’s accuracy is ~0.04mm line thickness. There is only a slight difference when you reach 0.05mm from the values below. I tested the printer by drawing a series of 0.01mm to 0.05mm graphic lines. When I attempt to actually print the artwork the Printer itself enchances those defects. ![]() ![]() There are almost greyscale edges along tracks and pins. There are blurred blobs and random spacing between pins. ![]() So I notice that no matter how hard I try, when I come to print out some artwork, even in the preview the result is highly inaccurate with legs misaligning with pins and a complete lack of consistency. (Make a copy of printer and change the copy) Change the driver through the properties of your Printer in Devices and Printers. Print SVG in Inkscape using Microsoft PWG Raster Driver. Load your SVG file into Inkscape and increase dpi resolution at this stage as multiples of the displayed dpi. TL:DR :- Windows messes up PDF files somehow. ![]()
