Hello all I have been given an image, it's a CGI of a building, that I need to resize to fit a hoarding at a train station. The JPEG I have been given has a size of 3527mm (w) and 2260mm (h), with a resolution of 72dpi. The hoarding has a width of 6135mm and a height of 1025mm. It has to be cropped a fair degree. Now the person I work with just inserts the image as it is into indesign and then just increases the size of the JPEG. The artwork in design would be set up at 50% size. Looking at the links panel in Indesign, the actual dpi is naturally at 72dpi but the effective dpi is 83. That person says the printer is happy with that set up. But should I not resample that image in Photoshop? I would got into the image size panel and increase the resolution to 144, with the resample box checked. Then when I bring it into Indesign, the actual dpi is 144 and the effective dpi is 166. Will this provide a better print quality but is my action in increasing the resolution irrelevant?? Sorry I am a be confused. I did post earlier on this subject and struggling to get my head around this issue. Thanks for your time.
