Plotting drawings containing JPG's

[Shizzjr]

I am trying to plot DWG's that have JPG's attached to it. Some of the JPG's have a white background. On those particular images, when they plot the white background is plotted as a series of dots. It almost looks like it is giving it a grayscale effect. Is there a way I can turn that off? Is it a setting somewhere? I just want the image to plot without any background effect. We are using OCE 9600 plotters.

Thanks

The problem sounds as if you scanned in an image and then inserted it into your drawings. It may look good from a normal distance, but if you zoomed in you would find that it's really not a white background, but a slightly different color (off-white).

There is no way to shut this off as it's truly part of the image. The only solution I know of is to clean up your image using an image editing program to make your background actually white and perhaps scan at a slightly higher resolution for sharpness (actually, scanning at a lower resolution may work better, the lower the resolution the less "dust" the scan will pick up). Another solution is that some scanning software will actually attempt to filter this "off white" color for you. Either way it will require a rescan of your image or some adjustments in a graphics program. (Hand drawn details are a great example where this "clean-up" needs to be done but are not always easy to fix perfectly.)
