I am concerned about exporting my book pages as jpg or pdf because of the compression each format applies. Any experience here? Thanks Sandy
You should just try it with some different settings for jpeg quality and open up the jpegs or pdfs to see whether they are acceptable quality. If you cannot see problems on your screen, they are not there. Both formats use jpeg compression but the quality setting should be good enough to not give any visible issues. At least that has been my experience. You should have your quality setting for jpeg above 75 or so but higher is typically not necessary. 300ppi is usually enough for printing from the files. sRGB is usually the correct color space to use except when you know your printing service knows what it is doing with regards to color management.
