I try to help my brother with images for his science article. First he just inserted images to .docx document(MS Office Word) but the publisher rejected it because:
"None of the figures can be edited. We need
to be able to edit lines, arrowheads, and fonts to match the journal’s
style. Each figure should be a separate ps, eps, fig, ai, Visio, wmf,
emf, Word, Excel, PowerPoint, opj, cdr, or PDF file which can be edited.
Please note that jpg, bmp, png, and tif files cannot be edited by
default."
So i made .psd files and 2 of 3 was accepted and 1 rejected. Here is one of them(unable to insert .psd here, so its screenshot only) which was rejected. The publisher says: "
Figure 1 still cannot be edited. The figures need to be in their original formats so that we can edit them and proceed with the publication process.". What do they mean? What's wrong with this .psd file?
