New to DPS. First impressions are very good.
However, when adding an Indesign page to Folio Builder as an article with the format set to PDF(to enble pinch and expand on iPad), the tiff images that are included in the Indesign page are displayed in very poor quality??
When I change the format to PNG or JPEG, in the article, the same images are displayed on the iPad with excellent quality - however, I dont have the pinch and expand functionality, which is what I require!!
I would really appreciate any solutions or suggestions on how this issue can be resolved.
Indesign CS5.5, MAC OSX 10.7, iMac
Yes but imagine high quality pictures even if you zoom. This means that you want the resolution to be two times to three times higher than the one native of the screen. This means also that the size of the embedded images would be from 4 to 12 times heavier !
With the artical format set to PDF the image quality is poor BEFORE I pinch and expand ie at the native resolution of the screen.
Is there a way to tell Folio Builder so create Hi Res PDF's??
Which iPad are you viewing your test articles on? Remember that the resolution for iPad 1 & 2 is 1024px x 768 px, while the iPad 3 resolution is 2048px x 1536px. Your images need to be formatted accordingly. Also check your image scale parameters. Anything above 100% scale of the original image will reduce the image quality. You can check this in InDesign before you ever test your article on the device. Simply press Command+1 to view actual pixel size and set your Display Performance to High Quality and you should be seeing something very close to what the final result will be. Also check that your images are RGB as well. Hope this helps.
I've actually converted my .tiff images to .png(and applying transparency) and it works a treat. Quite a lot of work but the results are good. The image scaling is fine.
PNG images have a tendancy to increase the folio size quite a bit. I've found by converting my tiff files to photoshop pdf with zero compression it has reduced my folio size whilst retaining good image quality across all i-pads.
