Problem: PDF print generates strange lines over hatch objects (ACAD 2012 LT)

I have created a logo which is included in all our drawings. The text part of the logo has been created by exploding a text object and hattched the remaining polylines. In in the model view all looks fine but when I print the drawing to PDF some gray lines appear over the text. If I plot the PDF to paper everything looks good, it is only the electronic versions that suffers from this problem. I need the electronic versions to hand out to our costumers so paper is not an option here and the print must look professional.

 

I have tried the following pdf generators, all with the same result:

Adobe

Autodesks built in DWG to PDF

Bullzip

Cute

 

I have viewer the result in both Adobe Acrobat 10 and Foxit reader. Both show similar problems. I can not find any solution to this problem. Can anybody help me out here?

 

I have attached two screenshots. One from the printed PDF and one from autocad model space.

PDFs will always suffer this problem. They may print out good, but they are images which do not have as much information in as needed ie 120 dpi instead of 600 dpi. If you want the lines to disappear in the electronic version, you need to set the dpi for the acrobat printer HIGHER

I have tried to set the dpi to max (4800 dpi) but the result remains the same.

 

Does anyone know if there is an other way around this problem then, I have seen many logos that is perfect in both DWG and PDF. Can I build my logo in any other way to make the PDF look better?

Just a s test WBLOCK the Logo into a new file.

At first I thought you were talking about extra lines that show up in plots from time to time but what you posted is not this. I've seen this some years ago and can't remember why.

 

Another thought would be to move the Polyline entities to 0,0 and then Hatch.

Set the HP ORIGIN to 0,0 as well before you Hatch.

AutoCAD draws solid hatches in triangles.

PDFs show everything.

 

No fix for the PDF display.

 

If you are concerned or need the display to be perfect, find a TTF font that does what you want instead of relying on AutoCAD's fills in outlines. But you will still have this issue in most AutoCAD solid fill/hatches anywhere else in your file.

I have this problem as well, searched for a solution other than the one I currently use.  Couldn't really find anything, and since I didn't see it mentioned on here, what I do is change my hatch style from solid to a cross-hatch style, and make the hatch very small.  It prints it as solid in PDF form.

Try using a different PDF reader, you may find that the problem dissapears. This seems to be a recurring problem with Adobe PDF Reader

If Acrobat reader OR Acrobat do the following

These are all good ways to solve the problem, how-ever since the PDF's I create usually go to other people who use Adobe Reader to open them, it is important to have them open and print properly on their end as well.  Short of sending along complicated instructions on how to open, display and print the PDF's I send, I will guess I will continue changing the solid hatches to a fine cross-hatch.
