Angled/Curved lines appear grey in PDF format

I've recently had to export DWG files to PDF and the lines print in black whether they are angled/curved or straight.  The problem I'm experiencing is that a number of objects that have been rotated at an angle or lines that are curved appear dark grey on the screen in PDF format.  I'm using the DWG to PDF. pc3 with monochrome setting selected.  I've checked the Plot Style Table Editor and all colours have been selected to print 'black'; greyscale is 'off' and screening is at 100%.  Is this a 'bug' or is there a fix for this problem?

 

Thanks

Anita

I use FOXIT Reader: I understand from others the current Adobe Reader does not have this problem, but I don't know that for a fact.

Just so that i understand correctly,

You print using the built in PDF printer, All lines etc are set to black, your plot style table is monochrome, and only some of the lines (not all) are printing in dark grey, while others print in black?

Which PDF reader are you using? Adobe Acrobat's current versions (9 and up) are notorious for screen-tricks to speed up their bloated software: actually check these "gray" objects by zooming in on them in the PDF reader you are using, bet they look the same as the straight lines next to them.

For many, plotting to an Adobe purchased PDF driver fixes the problem in Adobe Acrobat reader's display for some reason, not sure why or how. Using a different PDF reader seems to fix it for those of use not willing to pay Adobe any more money.

Yep, the printer selection is DWG to PDF.pc3 and monochrome has been selected in Plot Table Style.  I've deduced that only lines that are curved or angled (not using ortho mode) appear grey in PDF format.  I've created a test drawing to show this.

Pendean,

 

I'm using Adobe Reader 9.  I've heard that this is a common issue with Adobe - if you're suggesting using a different PDF reader which one should I use?

 

Thanks

Pendean is correct in his assessment of the fault. At first glance the pdf created seems to have grey lines on items that have been rotaed however if you zoom in a bit you will see that the lines become black. I suspect that if you print the draing from pdf to paper all will be well.

Yea, I'm sensing that the problem is the PDF Reader and yep when you zoom into the PDF the lines do become black but if you send this drawing to a client - for professional standards it would be nice if they could look at the entire drawing with consistent black lines without having to zoom in!  It just looks a little off when some lines are black and some aren't!!

 

Thanks for your reply.

Hi,

 

>> I'm sensing that the problem is the PDF Reader

And what PDF-reader do you use? For me it does not any line looks grey (opening with Acrobat Reader X).

 

Another question (again, as this was also asked by Nik-D): does it look grey if you print it? If no ==> that would be the same question I would ask your client.
