Please can you advise me ? I made posters in Inkscape, being equations on coloured backgrounds. I blurred the equations because I think it looks "artistic" :) I then saved the Inkscape .svg files to pdf files, and had a copy shop print them out. On printing, the text has acquired a rectangular background of a colour which contrasts with the rest of the page:
How can I avoid this ? On screen there was no such rectangle.
Opening the svg in internet explorer, it looks fine, i.e. there is no contrasting rectangle.
The Inkscape settings I used to save as pdf are: Restrict to PDF version 1.5. Convert text to paths: UNCHECKED PDF and Latex: Omit text in pdf, and create LaTeX file: unchecked. Rasterize Filter effects: checked. (Otherwise the text will not be blurred in the pdf file.) Resolution for rasterization: 300 dpi Output page size: Use document's page size Bleed / margin (mm) 0.0
I don't know how to work with Layers.
The svg code is here:
