One of my students has created a series of Illustrator documents she has File >Imported into Fireworks. The .ai documents look fine in Fireworks,
but the background gradients in the .ai documents severely band when she previews the Fireworks file in IE and Firefox. She has tried saving the .ai files as high quality jpeg and PNG files, but the banding in the Preview is severe regardless of quality she selects. I have checked her output quality in Illustrator, and it is at 300 ppi. We currently have Fireworks CS4. Is there any solution to this?
Thanks for any help.
As long as the images are displaying at the correct size in pixels, output resolution isn't a huge deal. As for the banding, make sure the graphic is being exported as PNG 24 - not PNG 8. You may need to slice the area and export it separately depending on how the design is layered. Prior to CS5, jpeg export could produce banding in certain situations.
If you can, please share the PNG with us so we can look into things in more detail.
Thanks much for your help. I will ask the student for a screen capture to send. In the meantime, she did have success exporting the file to a PDF format. The Illustrator images looked considerably better than before, and the PDF's interactivity is adequate for this project. I hadn't thought of slicing and will suggest that to her as well.
