Hi, this is my first post about printing issues.
Right now I’m using the next formula to calculate the resolution for "small" format prints (i.e 21cm x 29.7cm):
Final res = lpi x 2 x ampliation/reduction factor (in %) This way I’m getting reasonable values like 600dpi.
QUESTION is:
If I use same above formula for Big Formats like billboards, photo-calls etc I’d obtain incredibly huge file sizes (and my PC would get knocked down). So: How can I calculate/Know the final Res of my art knowing beforehand the final size of the art work (billboards and so on) ??
Any rule/formula/tutorial-link ??
Thank you very much in advance
