Note: Images should be the correct dots-per-inch (300 to 600 dpi) BEFORE saving as an .eps, .tif or .ppt file.
Please do not upload your figure(s) embedded in the manuscript Word document
We will reluctantly allow images to appear in the manuscript file, or be submitted as Word files, upon first submission only.
After the first review, however, we must have the .eps, .tif or PowerPoint image files before the revised manuscript will be accepted into the editorial office.
If we do not receive the proper source files upon revision the manuscript will be returned to the author until we do.
The manuscript text (including tables) should be uploaded in a Word document in the Manuscript File browse window. Figures must be uploaded separately as image formatted files. The images will be converted to PDF and appended to the manuscript file.
Images to appear in print should NOT be uploaded as supplemental files. If they are uploaded as such, they will not appear in the PDF file for reviewers. In order to go through the review process properly, the images must be included in the PDF. The system will do this for you automatically if the images are uploaded as image files.
Provide a legend or caption for each figure and include all legends together, properly numbered, at the end of the manuscript text file. Make sure each figure is clearly labeled.
Make sure that any multi-panel figures (i.e., figures with parts labeled a, b, c, d, etc.) are correctly labeled (Figure 1A, Figure 1B, Figure 2A etc.)
Do not place unnecessary graphics, such as a border, in or around your figure. Pay particular attention to the quality of the lines, symbols, and patterns; fine lines may disappear and heavy lines may plug up if the figures are reduced.
Types of Image Files Clinical Chemistry Accepts
EPS
EPS stands for Encapsulated PostScript file. PostScript was originally designed for sending to a printer but PostScript's ability to scale and translate makes it possible to embed pieces of PostScript and place them where you want on the page. These pieces are usually EPS files. EPS is considered a graphic file format.
Instructions for creating an EPS in most Windows applications:
TIFF
The acronym TIFF stands for Tagged Image File Format. TIFFs are bitmap images, which mean that they are made up of tiny pixels, and the quality of the image is dependent on the image file's resolution. The TIFF format is very common in graphic design. Most every image-editing program can create and save an image file in this format.
Most any image saving software, even Paint (under your Start menu, under accessories) can save your file to a .tif. Some may save as .eps (this is generally done through your printer).
If you will be saving your files as .tif files, please choose the "LZW compression" when saving so as to reduce file size. Remove any extra layers as well, if presented with this option.
PPT
PowerPoint is a software included in most Microsoft Office packages. If there are problems with .ppt images converting, it may be because the PowerPoint files need to have the fonts embedded properly.
Please open each PowerPoint file, choose Tools, Options, then the Save tab, and click embed TrueType fonts and make sure the embed all characters button is checked. This will help your PPT file convert more easily to PDF.
Be sure and choose a resolution of 600 dpi (dots per inch) when saving your image files. If you have trouble doing this on your computer, most office supply stores or major copy places will do a tif for you from your Word file or a hard-copy scan of your image.
Types of Images
LINE ART: Image is in black and white (Bitmap) only; there is NO graytone in image. 600 dpi minimum resolution
HALFTONES: Images with blocks or portions that are gray opaque. 300 to 600 dpi minimum resolution
COMBINATIONS: Images that possess both gray and line aspects. 600 dpi minimum resolution.
COLOR: Images where color is necessary to the meaning of the image. 600 dpi minimum resolution.
Formats that are not supported
Formats that are not supported include the following: Any file utilizing OLE (Object Linking and Embedding) technology to display information or embed files, GIF (.gif), JPEG (.jpg), Bitmap (.bmp), PICT (.pict), Excel (.xls), Photoshop (.psd), Canvas (.cnv), CorelDRAW (.cdr) and locked or encrypted PDFs. Multi-page PowerPoint files (.ppt) are not supported; one image per slide and one slide per file is acceptable. Please make sure fonts are embedded.
An Excel file can be converted into a tif, eps or PowerPoint file. If necessary, you can save it as a Word document then scan it through a scanning machine and choose tif (600 dpi) as the output. Also, if you have Photoshop or similar image software, you can use it to open the image (in Word) and choose 'save as' and save it as a tif by using the format drop down list in the save window that pops up.
The proper size for images
Published figures are reduced to I column (85mm) or 2 columns (176mm) in width. If, at that width, the figure symbols or lettering or, in particular, any subscripts or superscripts, cannot be read, re-letter them in a larger type size.
Generally this translates into images that are three to five inches in size.
Labeling
Clearly label each figure (Figure 1, Figure 2a, Figure 3, etc.) within the body of the image.
The x-axis and y-axis should be clearly labeled, and the units of measurement given. This includes using decimal points instead of commas, italicizing species or gene symbols, and using U.S. English.
Color
The costs of publishing color illustrations (figures and/or tables) will be borne by the author. Costs are $1500 for the first image and $500 for each subsequent color image, or part thereof.
Please state the author agreement to pay in your cover letter.
Color versions of figures may be provided for publication in the on-line Journal at no extra charge, with the figures produced in black and white in the print journal. Please notify the Clinical Chemistry editorial office at clinchemed{at}clinchem.aacc.org if you wish to have the images appear in color online only.
Proper Fonts to Use
Our printer supports the use of the following Type 1 PostScript fonts for the creation of digital art figures:
Asian fonts, in particular, do not convert well; be sure your text (including spaces), figures, and symbols do not use Asian fonts.
Do not use a type size that is unnecessarily large or that is smaller than 8 points.
