I'm printing out some color pictures I took and edited them in Photoshop at 1200 DPI. I'm printing them with my HP 600 max DPI inkjet and they come out very poor. In PS I did not enlarge the pictures or change the resolution so there is no quality loss there. It's for a school final project so I need the images looking as good a possible. When I print with my inkjet there are clear printing lines where the inkjet started a new line and the quality is poor looking at the pictures up close. Also the colors were kind of oversaturated. I was thinking of taking them to a printing store or kinkos where they have 1200 DPI laser printers. Would I notice a big difference between the 600 dpi inkjet print and the 1200 dpi laser print? Also would the oversaturation problem be fixed? Thanks a lot!
