I am not a graphic designer at all, but a science grad student. I need to submit figures to a journal in .eps format, they do not accept. pdf. When I try to convert my .pdf files to .esp, different components of the figure (plots, text) have different hues of grey instead of just being black. I strongly suspect it has something to do with how I made the figures, so let me outline my steps:
- Made plots etc in R, exported as pdf (these figures have a transparent background, not white)
- Used Pixelmator to combine plots, add text and make it all look fancy
- Export from Pixelmator as pdf
- Open pdf in Inkscape and save as .eps
I tried the .esp conversion with an online tool. Same issue.
When I look at the .eps and the layers in the Pixelmator file, it seems to be that the lower on the list a layer is, the greyer it looks in the .eps. So I merged everything in one layer in Pixelmator, then exported as .pdf and converted to .eps. Same issue.
I read some things about transparency issues for .esp conversion but I can't figure out if that's an issue. When I open the .pdf in Inkscape, everything shows up as one layer and the background seems to be set to white (checked with Ctrl-Shift-D -> background). Also, while the original plots from R have a transparent background, the eventual image I export from Pixelmator has a white background.
When I export my file as a .tiff or .jpeg (300 dpi) and convert to .esp everything looks fine, by the way. However, the file becomes huge (from 600 kB to 7 MB), and the journal has size limits for uploading figures.
I have limited knowledge of these file types and have exhausted googling solutions (that I understand).
Help would be so much appreciated!
EDIT/ADDITION: when I check the pdf exported from Pixelmator in Acrobat for layers, there aren't any.
