- What type of graphics are affected?
- What file types are you using?
- What polygons and images are you talking about? Screen shot?
- What export settings for EPUB do you use?
Moved to InDesign EPUB forum
First of all, thanks for answer:
1) Pages of catalogs originally created for offset print
2) For images: .psd from PS CC2015 / CMYK / 300 dpi for vector icons: imported from AI CC2015 also CMYK
3) Transparency given by filter "MULTIPLY" Missed
Seppia polygon with MULTIPLY filter on main image on the left completely missing
4) Format: Automatic / Resolution: 150 PPI
Mainly the very bad thing is that all icons and logos vector generated with AI, are rasterized and therefore are grainy!
- Images should be imported in InDesign as RGB, not as CMYK, even for print. http://indesignsecrets.com/import-rgb-images-indesign-convert-cmyk-export.php This would help to improve your EPUB result too.
- You might group elements with transparency settings before exporting to EPUB, so it can be realized.
- What file type are you using from Illustrator. I hope no EPS.
- How is the polygon put in the page?
- I think at the current state vectors become rasterized upon EPUB export.
These things are wrong in your ePub because InDesign can't do better for the moment. InDesign can't export vector images. They will all become rasterized. Also some effects applied to images directly are going to be ignored on fxl export. You need to flatten them with the image before the export.
Export for fixed layout is no 1/1 export like you know this from PDF. Some things need to be adapted. You might watch some of the ePub trainings on video2brain, lynda, trainsimple, etc.
@Willi: These aren't bugs. Only missing features.
Hi, Thank you both for answer…
I was afraid that ID could not export vectors but in webinars someone should specify that document exported are not exactly the same and some work is needed. Anyway I hope Adobe will improve this features as soon as possible…
I tried to group elements before exporting but nothing changes… and also replace CMYK images with RGB is not so quick to do because I have more than 200 images in document :-|
Thank you guys
Leave them for the moment in CMYK, but remember that you should not use CMYK in the future, but if the images have the same name you can relink them in one single step by relinking to another folder. With converting images to CMYK you do to much useless work. It was done in the last millennium so, but InDesign changed this workflow.
I know that this is not a bug, but I hope these missing features get completed one day soon. At least they were on the agenda once.
