I use Adobe Illustrator for my work and I am in the process of designing an infographic which needs to be printed and also put on the web.
I understand that I would be needing a 300ppi and 72ppi resolution respectively. For printing, the size should be A4.
Would it be wise if i create a 595px by 842px artboard and save it in 72ppi and 300ppi. Or, should i create a 2480px by 3508px artboard and save it in 72ppi and 300ppi.
