Manuscripts for review should be always submitted through our electronic submission system. The text part should be preferably in an editable form (not PDF); please switch on text line numbering to make the work easier for our reviewers. The final text accepted for publication must be supplied in an editable electronic form (preferably accompanied by a PDF file with all fonts embedded to ensure that uncommon characters are typeset correctly). Rich Text Format (.RTF) or MS Word (.DOC or .DOCX) files are suitable editable formats. Format the text as simply as possible and do not try to match the journal’s appearance, we will completely reformat all accepted papers and remove all formatting options except for italics and small capitals.

If possible, final graphics for publication should be provided in an electronic form in some common bitmap graphic format, such as Tagged Image File Format (.TIF). Non-bitmap graphic files are generally not accepted (if you really need to submit some graphics in vector form, please negotiate the format in advance with the editorial office). Never submit graphics imported into a word processor or presentation format (e.g., as .DOC or .PPT files). Required modes and minimum resolutions for bitmap graphic files: Colour in 24-bit RGB mode, 300–400 dpi at print size; halftones in 8-bit grayscale mode, 300–400 dpi at print size; line art in 1-bit black-and-white mode, preferably 1,200 dpi (and not less than 600 dpi for schemes, graphs, etc.) at print size. “Print size” refers to the journal’s page size which is 170x247 mm, column width 82.5 mm.
