Photoshop for print
 

Hi

I have a problem with scanning images from magazines for print.The problem is after scanning when i view the images in photoshop it shows the 'dots' at 100%.I would like to know if these images can still be edited and sent for print (I am working on a brochure.) Or will these dots us give poor image quality.I am using an hp2400 scanner and work on a PC.
Will appreciate if anyone has an answer.

Thanks
