Graphic Designing or electronic artwork is the prevailing and emerging service of this new era, which aims to enhance the quality of the images and figures used in the journal articles. Specific guidelines are set related to the image resolution, color specifications, dimensions, size, and file formats. We seek to provide key information regarding the publication of electronic artworks to a journal.
The first essential being the Image Resolution guidelines lay that the:
- Size of the image matches with the image size area in the journal
- Appropriate resolution for colored photographic images as 300dpi and for grayscale as 600dpi
- 1200dpi for line art or monochrome images
- Combination images at a resolution of 600dpi
File Format Specifications
The different file formats for graphic artwork accepted by journals are:
- TIFF (Tagged Image File Format)
In this format, the image is broken down into pixels to improve the sharpness. More pixels mean a sharper image with higher resolution. This format is recommended for photographic images.
- PS (PostScript) and EPS (Encapsulated PostScript)
These resolution independent formats can also contain TIFF images. Unless and until the line weights are not defined as 'hairlines', they generally do not have limits to scaling for line art. In high resolutions, these formats are recommended for line art and combinations images.
- PDF (Portable Document Format)
Similar to EPS, this file format is non-editable. While using PDF format, embedding of fonts and the appropriateness of image size and resolution are important.
- JPEG (Joint Photographic Experts Group)
This compressed format is recommended for online publication. Being a compressed format, it often discards some color information that makes it unfit for print publication.
- GIF (Graphics Interchange Format)
Alike JPEG, GIF format is again intended for online publication as it can be used for images with a few colors.
Journals usually have different requirements for the image colors. Some recommend CMYK (Nature) while some others want RGB (Cell). Photographs, half-tones, must be reproduced in colors on approval of journal editors.
Authors can use image editing software for some required manipulations to the graphics prior to submission. Some featured modifications deal with the following:
- Contrast Altering
- Sharpening and Brightening
- Flattening and Merging
