I have never done a poster before and got asked kinda last minute to put something together for a banquet. Sizing is only 12x18. Well, my wife picked up the print today and tried to describe the problem to me. She said it looked "blurry", well not blurry but "digitally". I have not seen the print so that's all I can tell ya.
What I did to create the print was simply create a background layer and pull images onto it. I obviously had to greatly manipulate the size of the images on the background to make them all fit. Did I do something wrong there or do I need to somehow resample the entire print to get it looking right? The file info shows the overall image pixel dimension to be x:3600 y:5400 and resolution at 300 for both.
I know the poster is not much to be proud of but like I mentioned, I have never done one and I had no advance notice at all so I just threw something together best I knew. Also, not all pics are mine but you gotta work with what you got. Can anyone help me on how to simply improve the print quality of the overall image or help with what might be causing what my wife described and how I fix it? I can email the .PSD or original to you if you think it would help.
Thanks very much, I have to have it done tonight so I sincerely appreciate any feedback.
Here's a large sample, as mentioned, the original is 3600x5400 and obviously too big for POTN.
