DPI Scaling AutoCAD

Anonymous — Wed, 13 Jul 2016 08:26:26 GMT

any valoue of dpi in jpeg,pdf,png printing, the result is always so 96 dpi for printing files always get a low resolution. I'm going crazy

Hi,

welcome @Anonymous.autodesk.com!

>> the result is always so 96 dpi for printing

The setting is nothing AutoCAD can choose, what you can define is the number of pixel in x and y direction. That is where you can select a better quality.

I'm sorry but my problem is not the size but the quality off the initial , in the sense that the line comes out grainy and blurry

Hi,

If you mean "comes out" that you then print the image, then plot to PDF, that would make the settings easier to understand.

Please understand that dpi does nothing tell you about quality.

If I send you an image with the setting "1200dpi" (which sounds really high) and the number of pixel = 600x600 and you try to plot that to 42"x30" you get thick, very thick pixels, if you plot the same file to 1"x1" then the lines and pixels are really fine.

So the setting "dpi" tells you nothing as long as you don't specify the size of the final output.

Looks like you need better line weight settings so everything is not so faint and thin: did you watch the video I posted? You can control line weights with that method most easily. "dpi" has nothing to do with the problem in your posted image.

If you're new to AutoCAD say so: line weights is a hot topic that must be mastered for best output performance.
