W the best print size?
I hope everyone is well.
I am wondering, what is the best dpi to use when printing out images? I know that the larger the number, the higher the quality will be. However, do many printers use 600 dpi? If I send something out to be printed, will they use 600 dpi? Or 300? I ask because I use software to either create or to enhance my projects. If I am painting on my computer, should I use 300 or 600 dpi? The same question is for photo enhancements, what then?
In addition, can someone please tell me if PNG is the better format, of is TIFF?
Thank you all much,
