Is it possible to plot an image in negative?

I use Autocad 2009

No.

You have to adjust it with another program before the upload.

With photoshop for example you should use the command invert.

If you don't have photoshop there are a lot of free apps for smartphone and tablets you could use.

You could use even MSPaint to invert the colors of the image.

You can also do this within Adobe Reader.

 

1. Print to pdf from Autocad and then open the pdf with your Reader.

2. Go to the Edit menu and select "Preferences"

3. Under Categories choose "Accessibility"

4. Enable "Replace Document Colors"

5. Set Page Background to Black and Document Text to White

6. Uncheck the option "Only change the color of black text or line art"

7. Check the option "Change the color of line art as well as text.

8. Click Ok to see the result

Be prepared with a couple of spare black ink cartridges.

Here is a way to do it with STB because I use STB, I am sure you could do the same with CTB's.

 

Plot for blueprint look using named plot styles (STB)

 

Cover PS in solid hatch, color 156

set to named plot style "Color 75%", set screening to 75%

 

Use HATCHTOBACK command.

 

Set up a plot style where all styles are set to plot 0% screening except "Color 75%" set to plot color.

 

Plotter pc3 set for lines over write.

 

Plot dialog, uncheck plot PS last.

A really nice free graphics package called GIMP is much more powerful than MSPaint.

Sort of related, if you just wanted a black printed background.

I suppose you could create a layer state where the colors are the opposite and use this if it's something you may need to go back and do a few more times.

The question is if you want to plot an image (like you wrote) or autocad entities.

For the image you have to invert it with another program which manages raster graphics.

For autocad entities it's enough using a ctb where all objects are printed with colour 255.

For the black/blue background you could use a solid hatch in true colour.

Maybe it could be useful to put this hatch in paperspace (remember to uncheck 'plot paperspace last' on plot window).

All of these various solutions offered, but no response from the OP. Oh well. Maybe this thread will help someone else in the future.
