Highly professional work that require greater colour accuracy might include other discrete spot colours, which requires the printers to have those colours available (usually identified by a unique code). For the most these spot colours are CMYK (your desktop printer might have a separate cartridge for each of these colours). My understand is that in the print industry, printing works with spot colours. Having said that, I'm keen to dig more information from you about this problem. So your professor would be right raise his/her nose at it. And Inkscape is an SVG editor and SVG, in it's current form, is a web standard not a print standard. I'm positive your professor knows more than I do about print (I'm not a professor and I don't own a print business ).

I don't know if this will yield the results you are looking for, but try giving it a shot Hit OK and a coloured vector image will show up. To trace with a few levels of colours, select 'Colors' in the Trace Bitmap window, and set the amount of scans to 5 (We use 4 because Inkscape recognizes Black & White as colours, so by having 5 scans, you will get a vector image of 3 colours + black/white). in this case, I guess it would be 256 scans (although I think this would make the file really large and I would suggest using a smaller number like 10, but feel free to experiment)Ī new grayscale vector drawing should appear on the canvas now (might take a little time to render, the bottom of the window should display the tracing progress) You can select the 'Grays' option and then modify the amount of scans (I think its 8 by default). You might want to select the 'Remove background' and 'Stack Scans' options (I would suggest have the 'Smooth' option unselected)

In the new window, look at the lower section where it says 'Multiple scans'. Go to Path -> Trace Bitmap (Shift + Alt + B) Select the imported image (import image by going to file -> import and then location the image)Ģ. Well, Inkscape does have options to trace in grays and colours:ġ.
