Hey, the image quality is so bad, that I can't think of a solution to make them print quality...
Ive increased the resolution to 240ppi and converted filr format into TIF-I dont know if this will surfice???
Ive increased the resolution to 240ppi
No, sorry, increasing the resolution of photo will never make it better. Reshoot the photos or find others in Adobe Stock or other stock service.
Do you have the budget to replace these with a stock photo? Or the time to reshoot with better equipment/settings?
You could also use these images a trace layer to sketch over in Adobe Fresco or Photoshop if an illustrated look will work.
Hi thanks for your recomendations so far Ive increased the resolution to 240ppi and converted file format into TIF-I dont know if this will surfice???
Increasing resolution and resampling and converting the format does nothing to put in pixel information that is not present in the original image, it just spreads the existing information over more pixels (and potentially adds more artifacts in the process) . If you need sharp detail then you have to start with an image that contains that detail.
Suppose someone brings you chicken soup. You wanted a chicken sandwich. Well, you can change a chicken sandwich to chicken soup, but there is no way to change chicken soup to a chicken sandwich.
These photos, great for use on screen, are the equivalent of chicken soup. Printers need a chicken sandwich; you just can't do it. No use messing with Photoshop, look for replacement images or don't do it at all.
