Dear Richard
I know a jpeg is lossy but I did say compressed to a SUITABLE size. That size will depend on requirements. Compressing once at a high quality level makes very little, if no difference, to the published result. What I was trying to clarify is that a Jpeg does not exist independently of a Tiff file. It is a Tiff file compressed.

A JPEG is a JPEG. The compression is lossy and the greater the compression the greater the loss. Just cos you change it back, it doesn't make it a TIFF again without the compression!!!

A Jpeg is a compressed Tiff. You have a Tiff and need to send it down the wire so you compress it at a suitable size. When they open it the other end they have a Tiff file. Simple. I do it all the time.
