When getting an InDesign file ready for print I knwo that images should be: 1. CMYK 2. at least 300 dpi 3.preferably .tiffs
But if the files are less than 300dpi but due to the size of the images on the page the 'effective dpi' is more than 300. Is that ok to send to print? Or do I still have to convert to 300 pdi which would make the effective dpi much greater?
