Guidelines for Preparation of Illustrations

2.0 - Provision of colour
3.0 - Journal covers

1.0 Preparation of illustrations

1.1 Image quality

·    Illustrations should be supplied as electronic files which conform to the guidelines given in the 'Acceptable Formats' section of the AJAM 'Author Guidelines' web pages.

·    If illustrations are unavailable in electronic format, high quality originals should be sent as hardcopy. Photocopies and printouts from inkjet printers are rarely suitable for print reproduction.                        

1.2 Image size

·    Illustrations should fit within either single column (8.3 cm) or double column (17.1 cm) width, and must be no longer than 23.3 cm.

·    Artwork should be submitted at its final size so that reduction is not required.                          

1.3 Text in illustrations

·    Lettering should be in 7 point Arial font (or Helvetica if Arial is unavailable).

·    Labelled atoms in ORTEP (or other) diagrams should have (selected) atom numbers in parentheses, e.g. Cl(1), C(12).

·    For graphs, axis labels should use SI units, separated from quantities with a solidus ( ' / ' ) not parentheses, e.g.  /nm, T/K; percent (%) and parts per million (ppm), however, should be given in parentheses.

·    Units should be in the form, e.g. g cm-3 rather than g/cm3.

·    Symbols representing physical quantities should be given in italics, e.g. E/V, t/s.

·    Curves should be labelled (A), (B), (C) etc. and parts of figures (a), (b), (c) etc., and further information given in the figure legend.                   

1.4 Line drawings

·    Lines should be black, of an adequate and even thickness (e.g. 1 pt) and curves should be smooth.

·    Broken, dotted and dash-dot lines can be used.

·    Particular care should be taken to ensure that the lines in spectra are of an adequate thickness.

·    Mark data points on graphs with simple geometric symbols: 

·    Avoid shading (tints) that simulate grey and use cross-hatching if appropriate.                   

1.5 Structural formulae

·    Structural formulae should ideally be prepared with chemistry drawing software (e.g. ChemDraw, ChemWindows, ISIS/Draw), using the settings given below.     

o   Chain bond angle = 120o

o   Fixed bond angle = 15o

o   Bond length = 0.43 cm or 12.2 pt

o   Bond width = 0.016 cm or 0.5 pt

o   Bold bond width = 0.056 cm or 1.6 pt

o   Double bond space = 20% of bond length

o   Stereo bond width = 0.056 cm or 1.6 pt

o   Hash spacing = 0.062 cm or 1.8 pt

o   Captions/atom labels = Arial/Helvetica, 7 pt              

 

·    Number structures with bold arabic numerals, e.g. 1, 2.

·    Schemes and structures should be drawn to make best use of single and double column widths.                   

1.6 Colour

·    Colour should only be used where scientifically necessary, unless otherwise stated for a specific journal.

·    Avoid shading (tints) and use solid, clearly distinct colours.                   

1.7 Photographs

·    Please provide either high quality digital images (see Acceptable formats) or original prints. Computer print-outs or photocopies will not reproduce well enough for publication.

·    Colour photographs rarely reproduce satisfactorily in black and white.                   

2.0 Provision of colour

2.1 Printed journals

Colour figure reproduction in printed journals is normally provided free of charge if there is a scientifically compelling case for the use of colour. The provision of free colour reproduction is determined by consideration of whether or not the scientific information can be understood without the use of colour. If colour is not scientifically justified, then black and white artwork should be provided, or if the author prefers colour, then the author will be charged a partial contribution to the additional production costs, as follows: 

·    1000DA  for one page or 500ODA for the whole article (+VAT; value added tax).       

Specific advice may be obtained from the Managing Editor of the journal to which the contribution is to be submitted. The Managing Editor's decision is final.

It may be possible – if black and white versions are provided – to reproduce the colour version free of charge as electronic supplementary information (ESI). (ESI is a service that allows data to be made freely available via the RSC website. In the text of the article a location will be given where the ESI that supports the paper can be found). 

2.2 Electronic-only journals 

Colour is free for electronic-only journals (e.g. CrystEngComm) and its use is encouraged.

3.0 Journal covers

Authors who wish to have their artwork featured on a journal cover should contact the Managing Editor of the journal to which the article is being submitted. A contribution to the additional production costs will be requested. Use of such artwork is at the Managing Editor’s discretion; the Managing Editor's decision is final.

Examples of previous journal covers can be viewed via the relevant journal homepages.

Authors whose artwork is featured on a journal cover receive low and high resolution JPEG files of their cover feature for their own promotional use.
