Re: Resolution for professional printing
[quote="mal1e":64xcp9tn]However, I remember hearing the cover shot has to be a higher resolution. Is this true?[/quote:64xcp9tn] I have never heard of this - 300dpi is normally perfectly adequate for printing. Before you do anything else, you should contact your printer and find out the facts - you could be wasting your time with all of this image resampling. The process that you have described is correct - it's really the only way to 'increase' resolution. Such a huge file size is to be expected with a large image at 600dpi, and it is almost certainly this that is causing Acrobat to crash - I would recommend sending the image to your printer separately without exporting to PDF (exporting will only reduce the quality of your image, anyway). For the purposes of sending a draft to your friend, you'd be better to make a copy of the cover image that has been down-scaled and optimised for screen viewing - your friend certainly doesn't need to preview the cover at 600dpi!
