Image Editing

When preflight is skipped, the Image Editing task is not automatically assigned to anyone and you can go ahead and take the task. When an article is preflighted, however, the Image Editing task is automatically assigned to the preflight editors. 

1. Take the Image Editing task. If preflight had been skipped, download the files in the Author Supplied category by going to the "Build zip file" link at the bottom of the page. If the article had been preflighted and the editors have uploaded the final files for us to use, files under the Accepted category will be downloaded by clicking the Download link within the Image Editing task.

2. Run ImageTwin; see instructions below.

3. Figures, with the exception of headshots, must be tif files. Convert if necessary and open in Photoshop. Videos must be mp4. Add JEM logo to front matter figures. Details for how to convert files, what to check and fix in Photoshop, etc. are given below.

4. Create an article thumbnail. Crop an image and make it an 80 x 80-pixel square at 72 dpi. Save as a gif file.

5. Create a single PDF named JXX202XXXXX_combfig.pdf that contains all figures (main and supplemental); this will be used by the TNQ copy editor.

6. Rename files to remove the _AU (see Workflow manual for proper file names) and upload all files (Word, figures, supplemental tables - everything production needs) using the "Upload Production Files" link. Click "Complete Task."

A video recoding of ImageTwin training can be found on Dropbox.

The merged article PDF can be used (delete the pages with text), but there is a 30-MB file limit for a PDF. You can also download individual figure files to use (20-MB limit per figure). PowerPoint and ai files cannot be used; covert to tif (make sure to flatten the image and save with LZW compression) or use the existing PDF files. jpg, jpeg, and png files can also be used.

Drag and drop files. Upload all images so that the entire ms can be scanned at once. This is needed so the tool can check for duplicates across all figures. (However, there is a limit of 25 images.) Click Scan.

Analyze the findings. If you see blots in the figures and the article skipped preflight, ask the scientific editor if the article was supposed to go to preflight before proceeding further. Clicking “Area” pulls up a direct comparison of the duplicate areas the tool is flagging. Identification of duplicate images in a zoom should be ignored. 

If an image is flagged as being in another publication and it's the article's preprint, that's ok. If the title and/or author list of the preprint do not match the article you're working on though, it should be flagged for the scientific editor.

When you identify something as a false positive, click the eye next to the finding to mark it as seen.

If there are findings you cannot clear, generate an ImageTwin report. Email it the scientific editor. If the editor ok’s the findings, proceed with Image Editing. If the editor wants anything investigated further, email the preflight editors, attaching the ImageTwin report, and ask them to open a preflight task. Release the Image Editing task (it could take days or weeks for preflight editors to clear the paper).

Convert

Illustrator: Keep embedded color profile. If you get font errors, compare against an EJP file to make sure nothing changed; find and replace the font with an appropriate font in the system. Make sure there are no empty boxes. Alternatively, open the file in Photoshop; the text usually does not drop out, but double check. Export to TIF: RGB or grayscale color model; minimum resolution is 300 dpi, but there's no reason to export that low unless there's concern about file size (ideally at least 600 dpi for color and grayscale and 1,000 dpi for black and white); LZW compression; IBM PC byte order; “Art Optimized supersampling”  anti-aliasing.

PowerPoint: Save the ppt file as a PDF, and then open that PDF in Photoshop.

PDF: Open in Photoshop. Pick the appropriate dpi, make sure the color mode is appropriate, and save as a TIF file. Check the color settings and convert to the correct working space. RGB or grayscale color model; minimum resolution is 300 dpi, but there's no reason to export that low unless there's concern about file size (ideally at least 600 dpi for color and grayscale and 1,000 dpi for black and white); LZW compression; IBM PC byte order; “Art Optimized supersampling”  anti-aliasing.

Photoshop

Upon opening, keep embedded color profile (change it later).

Clean up

Panel letters should align with each other

Graphs should generally be aligned on their left/bottom axis

Trim excess white from edges using Image/Trim or the Crop tool

Flatten image: Layer/Flatten Image

Settings

Choose the correct color profile (Edit/Convert to Profile): color = Adobe RGB (1998); grayscale (GS) = Dot gain 20%; line (blank and white) figures = Dot Gain but with Bitmap mode (convert using 50% Threshold). Black Point compensation = on; Dither = on.

Check Window/Channels: only Red, Green, and Blue channels should be listed. Delete "Alpha" if it exists.

Image/Mode: Indexed color should not be checked (the exception is thumbnails). 8 bits/channel is the correct bits choice.

Resolution: 300 dpi minimum; ideally at least 600 dpi for grayscale and 1,000 dpi for line (black and white).

Save as LZW tiff compression. 

JEM logo

The JEM logo needs to be added to all non-headshot images in JEM front matter and reviews: Insights, Viewpoints, People & Ideas, Found in Translation, Reviews, and Perspectives. The logo file can be found here on Dropbox: Rockefeller University Press/Production/JEM_files_production/Logo for Front Matter Article Images

1. Depending on the figure, you might have to increase the canvas size so there’s enough white space at the bottom. Go to Image/Canvas Size and add a few picas to the bottom. You can trim as needed later. 

2. Open the jem-oneline-rbg LEFT.png file. The overall width should be 11 picas wide, although the width of the actual logo is ~10.4 picas. Adjust the resolution (resample) to match the resolution of the figure. 

3. Paste the logo into the figure in the bottom left corner. Flatten, trim white space, and save as usual.
