What is the standard setting for low, med and high print resolution when exporting (under Compression menu) a PDF file from InDesign at an in-house studio?
Any resolution would be highly dependent upon the capabilities of the print device(s).
For most end use Inkjet printers 150dpi is as high as is necessary.
Some higher-end inkjets, with a RIP, are capable of supporting 300dpi. As are laser or wax printers.
These are typically the only two numbers you need for printing resolution. Anything lower than 150dpi would be of lower quality. The lower the resolution, the lower the quality.
