Protel negative

Same answer as I gave to your identical post in sci.electronics.design, i.e: "If Protel 2.8 has no built-in facility for that, copy the image to an image editor which does, such as Paint Shop Pro."

....also, JPEG does lossy compression, adding noise to the image which can be objectionable. The geaer the compression, the worse it becomes - to the point of pictorial gibberish.

Like Terry said, you need to use an image editor like Paint Shop Pro.

First you need to convert the layout to a raster image (i.e. a bitmap, such as a GIF, TIF or PNG file).

I use a freeware print capture program called PDF Creator (sourceforge.net/projects/pdfcreator), which can capture to raster files as well as to PDF. Use PFW's print feature. Capture at 600 dpi, and if you need more detail, "print" the image at 2x scale. (This will make the file larger, of course.)

Save the captured file as a GIF or PNG file (don't use JPG, it's designed for continuous-tone images not for sharp contrast diagrams). Then load the image into an image editor such as Paint Shop Pro, crop it (to save processing time), and convert it to negative.
