Angled/Curved Lines Appear Grey in PDF Export

502 Views, 6 Replies

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

Hi,

 

if you can recreate the issue in a new drawing, then create such a drawing and upload it, parallel to a PDF you created from this drawing so we  can try to get that reproduced (or not :smileywink: ).

 

My only idea I have at the moment is that either you have the option "transparency" on in the plot-dialog or you have activated visual styles other then 2D-wireframe to any of your viewports.

anita.brown76,

just another idea,
the objects or the layers have true color,
if so, change the color to an Color Index.

Alfred,

 

Thanks for your reply.  Here is a test drawing that I've created (these are supposed to represent chairs in a room).  So, you can see that if I have straight lines (the second chair has been rotated using ortho mode) the PDF document shows the lines as black but if I rotate the chair without using ortho mode the lines appear grey.  This also happens (i.e. black lines in AutoCAD appearing grey in PDF format) when curved lines have been applied.  Again, the printer selection is DWG to PDF. pc3 and monochrome has been selected in Plot Table Settings with all colours being selected as 'black'.  Any assistance to address this would be appreciated!!

 

Thanks

Anita

Henrique,

 

Thanks for your reply.  How do I change the colour settings to 'colour index'?

 

Thanks

Anita

Anita,
your colors are already AIC, AutoCAD Color Index, colors from 1 to 255,
in your pdf it appears that the inclined lines and the arc, are gray,
but if you do a zoom too close to the lines you will see that they are black ...

Hi,

 

>> but if I rotate the chair without using ortho mode the lines appear grey.

As hmsilva already mentioned, he get the lines visualised as black with a higher zoom-factor, I get the lines from your pdf (also the non-ortho ones) visualised in black.

What viewer for pdf do you use?

When you print that file, do you also see that lines grey on your printout?
