I was having problems with Scribus crashing because the total size of all my images files was too large. So now I'm in the process of reducing the file sizes. [I posted something about this on another board and got given some links by user GarryP with a lot of detailed info, but I suspect the answer I'm seeking is quite simple.]
I'm working with a few dozen A4-sized drawings which I scanned in at 600DPI, so the images are currently TIFFs, each in the order of 50-100MB. I realise now that this is unnecessarily high-res (in print, the images are going to appear typically 5-10cm wide/high).
In GIMP, I can separately set the DPI of, and resize, my images. But I'm finding it hard to get clear information on the optimal settings for images within a .sla as regards the final printed output.
I've noticed Scribus gives warnings when I export to PDF if an image is below 144DPI - what's the relevance of that figure? I also read somewhere I should be using "at least 300DPI" for printing purposes. But would higher DPI lead to a better image quality? Or is 300 some kind of cut-off above which it doesn't matter?
Some simple advice on how to resize/prepare images before inserting them into my .sla (for best printed results) would be very welcome. Thanks!
