Geoff,
Admittedly before attempting to try, I don’t actually envisage a problem in converting my jpeg pages to a pdf format, whether via Page Plus, or, if necessary, I do happen to have an Old Abby Fine Reader program that am sure would do the job if necessary.
As to the number of potential books of any project or number of pages? I think that is something like the ‘chicken and egg question, what came first.’ At the moment I cannot envisage wanting more than 1 or 2 copies, and as to number of pages, that for me I think, would be determined by cost and how easily I could split a Project.
These will be all A4 page books. Although I think everything I have done has been within the blue Page Plus Guide Lines, what I was more hoping for was to have an idea of what the finished book would look like before deciding to go ahead.
Hence my ideal of transferring page(s) to a template and then getting a green tick, or, a red cross as to whether it was suitable for that printed book design. Maybe this is just wishful thinking or I await a future Ai.
George
