Setolam a écrit :Hello, I think that png format is better and maximun scan ppi too, but size will be increment some times, for preservation purpuses the ideal one will be at least 600 ppi and png or jpg without any compression and preserve too the raw because it is better for future new retouchs that to use a previus used files.
But in the other side I do not use 1200ppi files because I will need a big hard disk only for files and we do not know how much is nintandbox space and the worse the bandwidth for support it.
I have Actraiser in:
600 ppi and it needs 298MB for PSD file
300 ppi its only needs 80MB
Png at 300 is 32MB
and 17MB for Jpg.
for A3 box.
In the other side we have box for print that I suppose that is the most use of the boxes, then when you print it, the quality depends of other factors like paper quality, printer, etc. And 300 ppi if you do not check very near box you cannot see difference between 300 or 600 ppi quality, I am not a expert because I do not print box, but maybe you only can see difference in texts.
Anyway always is better quality, you can send bigger sizes files and the somebody can check and choose if make it small or preserve like it. You can put too in external space like archive or other places.
Regards.
