Plotting viewport with “Rendered” visual style to PDF is putting glitches in the image

Contents

Issue:

Objects in the viewport was set to “Rendered” visual style as the goal is to render from a model directly to a PDF layout with high quality plot. However, the results in the PDF look blurry and the overall image quality is poor.

Sometimes the less color option was throwing funny shades of beige where it should be white background. A high DPI on the PDF will result in high quality and to allow user to zoom in our PDF and still be reasonably clear. A true DPI of 300 would be great to achieve, however using 300 DPI in that plotter results in something that looks much less than 50 DPI.

Solution:

  1. Plot the viewport which was set to Rendered visual style as image format such as PNG
  2. You can use PublishToWeb PNG.pc3
  3. To increase the resolution of a PNG file, creates a customized paper size or changes the printable area of a standard or nonstandard paper size. With the Custom Paper Size wizard you can create a new paper size, or select from a list of available paper sizes (from a PMP file) if the plotter is not a Windows system printer. If the plotter is a Windows system printer, use Custom Properties.

  1. Starts the Custom Paper Size wizard. When you add a paper size, you can either create a new paper size from scratch or create a new one based on the listing of available paper sizes for the selected configured plotter. The new paper size is a user-defined size, not a standard size. Example: 
    • 1 unit x 1 unit at 100 dpi is 100×100 pixels.
    • 2 unit x 2 unit at 200 dpi is 400×400 pixels.
    • 2 unit x 2 unit at 300 dpi is 600×600 pixels.
    • 10 unit x 10 unit at 600dpi is 6000×6000 pixels.

  1. Attach the PNG/image in the drawing.
  2. Plot to PDF with a custom DPI setting. See How to improve pdf quality when exported/printed from dwg in AutoCAD
