Hello all - I'm having an issue with some images inDesign that look great in the file, but when I export to Interactive PDF they edges get these little line artifacts. The links aren't broken, I'm exporting with 300 DPI and lossless JPG. On a Mac with newest version of Indesign. Thanks!
What format are the icons in, natively? And approximately what's their size?
And if you export to a print PDF, do the artifacts appear? I'd bet this is a case where the export mode demanded by interactive is not handling flattening and resolution details correctly. Not my area of expertise but I've seen similar discussions.
PNG, 70kb, 866x866 pixels, sRGB IEC61966-2.1
Hi @Robbie5C9C , Can you share the icon images? Or, try adding some padding to their canvases in Photoshop—what you are showing can happen on a downsample when there are no pixels beyond the edges to interpolate with.
100% better - I can't believe it was something so silly - especially since Illustrator automatically narrowed it to those margins. Thank you so much! It is very much appreciated
This can occur on PNG/JPGs that have color pixels right up to the edge. The downsampling creates the artifacts on two edges.
Expand your PNG/JPG graphics to include a several pixels of white on all four sides. (really it only needs to be on the right and the bottom)
Use Average Downsampling instead of Bicubic.
Do Not Downsample. This of course may not be a good solution for other images on your page, but it will solve the issue.
