FIGURES / TABLES
Figures/Illustrations (if any):
All authors must strictly follow the guidelines below for preparing illustrations for publication in The Open Chemical Engineering Journal. If the figures are found to be sub-standard, then the manuscripts will be rejected.
The authors are expected to submit good quality figure(s) in PDF, PPT, MS Word, TIFF or JPEG versions, which, if required, should be improved yourself or by professional graphic designers of your organization/ country. You may even consider approaching our contracted service providers Eureka Science for Graphics Enhancement Services.
The Graphics Designing team at Eureka Science can assist in improving the quality of your images at affordable rates. Eureka Science has contracted special rates with us of US $135 for the improvement of up to five figures, with any additional figures being charged at US $21 each.
The quality of Graphic Enhancement Services offered by Eureka Science can be viewed at http://www.eureka-science.com/images/Binder1.pdf, along with valuable feedback on their services at http://www.eureka-science.com/testimonials.php. You may contact Eureka Science at firstname.lastname@example.org
Note: Availing Graphics Enhancement Services do not guarantee acceptance of the manuscript for publication. The final acceptance/decision on the manuscript is taken by the EiC.
Guideline for Figures/Illustrations
Illustrations must be provided according to the following guideline:
- Illustrations should be embedded in the text file, and must be numbered consecutively in the order of their appearance. Each figure should include only a single illustration which should be cropped to minimize the amount of space occupied by the illustration.
- If a figure is in separate parts, all parts of the figure must be provided in a single composite illustration file.
- Photographs should be provided with a scale bar if appropriate, as well as high-resolution component files.
- All the numbers, symbols and letters in figures should be consistent and clear throughout and large enough to remain readable when the size is reduced for publication.
- It must be ensured to cite each figure in the text in sequence.
Line Art image type is normally an image based on lines and text. It does not contain tonal or shaded areas. The preferred file format should be TIFF or EPS, with the color mode being Monochrome 1-bit or RGB, in a resolution of 900-1200 dpi.
Halftone image type is a continuous tone photograph containing no text. It should have the preferred file format TIFF, with color mode being RGB or Grayscale, in a resolution of 300 dpi.
Combination image type is an image containing halftone , text or line art elements. It should have the preferred file format TIFF, with color mode being RGB or Grayscale, in a resolution of 500-900 dpi.
Illustrations may be submitted in the following file formats:
- EPS (preferred format for diagrams)
- PDF (also especially suitable for diagrams)
- PNG (preferred format for photos or images)
- Microsoft Word (version 5 and above; figures must be a single page)
- PowerPoint (figures must be a single page)
- JPEG (conversion should be done using the original file)
- CDX (ChemDraw)
- TGF (ISISDraw)
Bentham OPEN does not process figures submitted in GIF format.
For TIFF or EPS figures with considerably large file size restricting the file size in online submissions is advisable. Authors may therefore convert to JPEG format before submission as this results in significantly reduced file size and upload time, while retaining acceptable quality. JPEG is a lossy format. However, in order to maintain acceptable image quality, it is recommended that JPEG files are saved at High or Maximum quality.
Zipit or Stuffit tools should not be used to compress files prior to submission as the resulting compression through these tools is always negligible.
Please refrain from supplying:
- Graphics embedded in word processor (spreadsheet, presentation) document.
- Optimized files optimized for screen use (like GIF, BMP, PICT, WPG) because of the low resolution.
- Files with too low a resolution.
- Graphics that are disproportionately large for the content.
Technical requirements for graphic/ figure submissions.
Image Conversion Tools
There are many software packages, many of them freeware or shareware, capable of converting to and from different graphics formats, including PNG.
General tools for image conversion include Graphic Converter on the Macintosh, Paint Shop Pro, for Windows, and ImageMagick, available on Macintosh, Windows and UNIX platforms.
Bitmap images (e.g. screenshots) should not be converted to EPS as they result in a much larger file size than the equivalent JPEG, TIFF, PNG or BMP, and poor quality. EPS should only be used for images produced by vector-drawing applications such as Adobe Illustrator or CorelDraw. Most vector-drawing applications can be saved in, or exported as, EPS format. If the images were originally prepared in an Office application, such as Word or PowerPoint, original Office files should be directly uploaded to the site, instead of being converted to JPEG or another format of low quality.
Chemical structures MUST be prepared in ChemDraw/CDX and provided as separate file.

- Data Tables should be submitted in Microsoft Word table format.
- Each table should include a title/caption being explanatory in itself with respect to the details discussed in the table. Detailed legends may then follow.
- Table number in bold font i.e. Table 1, should follow a title. The title should be in small case with the first letter in caps. A full stop should be placed at the end of the title.
- Tables should be embedded in the text exactly according to their appropriate placement in the submitted manuscript.
- Columns and rows of data should be made visibly distinct by ensuring that the borders of each cell are displayed as black lines.
- Tables should be numbered in Arabic numerals sequentially in order of their citation in the body of the text.
- If a reference is cited in both the table and text, please insert a lettered footnote in the table to refer to the numbered reference in the text.
- Tabular data provided as additional files can be submitted as an Excel spreadsheet.
- It is adequate to present data in Tables to avoid unnecessary repetition and reduce the length of the text.
- The citation of each table in the text must be ensured.
- Symbols and nonstandard abbreviations should be explained in the end of the text.
- All references should be numbered sequentially [in square brackets] in the table and listed in the same numerical order in the reference section.
