Hi,I'm working on AutoCAD 2007 and LT and I just got some old drawings made by someone else.The drawind is in coulor on a black background.Some of the lines are in yellow, blue, pink... and when I print the drawing in pdf, I have either :- color print : figures printed in yellow are unreadable- b&w print : i have shades of grey that are not easily readable either..How coul I go to tell AutoCAD that evey line in yellow, pink... should be printed in black??Thanks !

Hi Cyril,
you have several options:- on printing dialog box, choose monochrome plot style from plot style table list- edit plot plot style in editor (the button next to plot style list)regardsKarol

Hi,thanks for your help, works perfectly.Just another problem though...Before I had some of the lines and text that were quite thick when printing (but very thin on the model).To get thin lines when printing I used to uncheck the box "plot objects lineweights" (in page setup manager).But now, to be able to print in monochrome, I have to check the "plot with plot styles" which automatically check the other obx :(So i get nice monochrome drawings but with thick lines.I can explode the model, then change manually the line thickness to 0 but it's long (I have loads of drawings to print), I have to modify the drawing (which I don't want to) and it doesn't work the for text.Any idea on how to solve this ? (and how to save it somewhere so that I don't have to set monochrome/thin lines everytime I open a file ?)Thanks !!CyrilP.S : didn't find "edit plot style editor" as you said above (2nd option).. :(

no problem,right, here you'll need to choose the second option - printing with color dependant plot style:When at plot dialog box, go to the plot style list, at the end there is "New.." option. This let's you to create new ctb plot style. In the wizard choose "start from scratch", give it a name, choose plot style table editor and here you can choose properties dependent on color of lines.I hope it helped.

ok, found it this time ;-)So I guess now I have to select all the plot styles and set up a lineweight of 0.0000  mm and select grayscale "Off" (or should I change the color from "use object color to black?)?Do you know what is the dither option for?What should I do to correct the text being too thick (or bold) ?Thanks very much for your help !

it depends what you want. If you want black lines, you have to change it to black. 
Here is a small video tutorial I found some time ago and I used it once to teach some colleague of mine:http://www.andrew.cmu.edu/course/48-568/2DVideos/Chapter9_Plotting/9.5.0_AddPlotStyle.html

P.S : Just tried to select all plot styles at once and change the lineweight to 0.0000 mm, select save and close.....but when i open the editor again I still have the "use object lineweight" value instead of 0.000 mm :(cyri_l132010-04-12 17:16:17

ok, i will check the video later, I cannot watch it from work :(but yes, what I want is to print the lines in black (but still keep them in yellow, pink... on my draqing (black lines on a black background would be a mess ;)Edit : just tried to put all lines in black and greyscale off but I still get a grey scale..... :( :(

oh, finally seems to be working....the printer was still in black an white so probably interfered with the monochrome "order" of the ACAD plotter...anyway, I have thin, black lines and readable text now !!thanks very much for your help and time !Cyril
