Hi John, The eBook would be designed correctly for the Web & iPad and would have an RGB profile or equivalent.
As Daniel already asked … have you tried other PDFs on the iPad. I would suggest it is only this particular PDF that you are having this issue with. I have never had a problem viewing colour PDFs on the iPad. Ones I create myself, or any other PDFs , eBooks etc. Cheers, Ronni On 17/04/2011, at 12:06 PM, John Hatch wrote: > Roni, > > Thanks.
