Preparing graphics

Guidelines

  • If you embed figures in place in your article-text file, you will be asked to upload individual figure files if your paper is accepted for publication.
  • Number figures in the order in which they appear in text.
  • Identify all figure parts with (a), (b), etc. Avoid any large size differences of the lettering and labels used within one illustration.
  • Submit illustrations in the size and resolution you wish them to appear in print.
    • For ADV, APL Bioengineering, APL Materials, APL Photonics, BMF, JRSE, and SDY (online-only journals)
      The maximum published width of figures is 5 3/8 inches (13.65 cm). The maximum depth of figures should be 8 ¼ in. (21.1 cm). Legends or labels within figures should be a minimum of 8-point type size (2.8 mm high; 1/8 in. high). A minimum of 0.5 point width for lines.
    • For JMP (one-column journal)
      The maximum published width of figures is 6.69 inches (17 cm).
    • For APL, APR, CHA, JAP, JCP, JPCRD, Physics of Fluids, Physics of Plasmas, and RSI
      The maximum published width for a one-column figure is 3.37 inches (8.5 cm). The maximum width for a two-column figure is 6.69 inches (17 cm). Each illustration should be prepared for 100% reproduction in order to avoid problems arising from large reductions in size.
  • Ensure that lettering and lines are dark enough and thick enough to reproduce clearly, especially if reduction is necessary. Remember that fine lines tend to disappear upon reduction.
  • Color online only (RGB) is a free service; Color in Print (CMYK) may require fees (see Color Printing Charges).
  • IMPORTANT: All fonts must be embedded in your figure files.

Electronic graphic formats

  • Use these file formats only: EPS (preferred format), PS, TIFF (.tif), PDF, JPEG (.jpg). Application files (e.g., Corel Draw, Microsoft Word) are not acceptable.
  • Scalable vector formats (i.e. EPS and PS) are greatly preferred. AIP Publishing suggests the use of Adobe Illustrator (Paid, OS X, Windows) or Inkscape (Freeware, OS X, Windows, Linux) for the creation of acceptable illustrations and Adobe Photoshop (Paid, OS X, Windows) or GIMP (Freeware, OS X, Windows, Linux) for the editing of acceptable photographs.
  • Submit a single file for each figure with figure parts; label each part (a), (b), etc.
  • When submitting your manuscript, include all illustrations and line art for your paper.
  • Set the correct orientation for each graphics file.
    • Set the graphic for:
    • Line art: 600 dpi resolution and black/white bitmap, not grayscale.
    • Halftones: 264 dpi resolution and grayscale, not black/white bitmap.
    • Combinations (line art + halftone): 600 dpi and grayscale, not black/white bitmap.
    • Color: 300 dpi TIFF, PS, or EPS format. If selecting a file mode, use CMYK (cyan, magenta, yellow, black) for color figures in print or RGB (red, green, blue) for color figures online only.

Production-ready PDF graphics

For accepted manuscripts, PDF as the source file for illustrations is not preferred. However, properly prepared PDF illustration files may be used in the production process of your accepted manuscript if you follow these guidelines:

  • PDF should be used as the source file for illustrations only when the preferred formats (PS,EPS, or TIFF) cannot be generated
  • In the PDF illustration, the resolution of any shaded or photographic images must be 600 pixels per inch (PPI).
  • Within the PDF illustration, resolution of line art with no shading should be 1200 pixels per inch (PPI).
  • All fonts must be embedded in the PDF.
  • When creating a PDF through your application’s print command, select “High Quality Print.”

Color

  • Illustrations will appear in color in the online journal free of charge to authors. To take advantage of this free service, you must:
    • supply color graphics files in the appropriate format (.eps, .ps, .tif, or .pdf only),
    • submit graphics files in time for utilization during the production process,
    • submit only one version of each graphics file,
    • ensure that colors chosen will reproduce well when printed in black & white, and
    • ensure that descriptions of figures in text will be sufficiently clear for both print and online versions.
  • If you want color figures in the printed journal, you must request this at the time of submission.
  • You or your institution must pay the required fee of $325 per color figure. Note that there is no charge for color figures in JCP. For multipart figures, a single charge will apply only if all parts are submitted as a single piece of artwork.
  • For color in the printed journal, you will be required to sign an acknowledgment of color charges prior to publication of the article. Otherwise, the figures will appear in color only online and in black & white in print.
