over the past few days I worked myself into LibreCAD 2.1.3 to created a technical drawings for a hand rail. The drawing turned out quite nicely. Now it was time to get it printed.
Since I do not own a A3 printer I wanted to export the file to PDF to have it printed elsewhere.
While the image in LibreCAD looks like this:
The PDF export turned out a little different. I was a bit disappointed about it.
The exported lines were rather coarse.
The biggest problem is that the geometry for the 5mm holes are lacking detail, because half of the dots for the dotted lines are missing and are way to thick. Those are the smallest dots in LibreCAD (tiny dots). So I ran out of ideas on how to get a more detailed export.
I tried to "Export as image" and chose SVG. But the result was even worse than the above image. Now the numbers where all mangled.
Exporting as JPG creates a half way decent image, but the line widths seem to be off. Everything is super thin and the lines have compression artifacts.
Exporting to TIFF creates an image without artifacts but at a size of 200MB per export, where the line widths still look too thin.
The image resolution for both images is 10080x7128px (~430DPI) which should definitely be high enough to create a smooth and close to perfect image. A 0.35mm line should be 6 pixels wide, but the thickest line 3 pixels which look like this:
When exporting the image I had to choose at least a resolution of 3 to get a half way decent image. Anything bigger than 3 creates an empty image.
Any help on how to export a nice quality image are greatly appreciated.
Thank you a lot in advance...
