Placing transparent graphic header in Table
Hello! I'm brand new to InDesign using CS6 on a mac. I have been trying all day to place a transparent header from Photoshop into InDesign and I keep getting what appears to be a SUPER low resolution image. So far, I've changed the preferences to view both the app default and specific images in high quality display performance mode. I have used .png, .tiff., .psd files—all of which look great to my eye at 300 dpi (7.2" x 1.2") in their native apps and in InDesign have actual and effective 300 ppi after being placed. The InDesign file prints how it appears after being placed. I've recreated the header image in Photoshop plus used a different program—always duplicating the same poor quality results after being placed. Does my problem have something to do with placing into a table? I watched one video online that suggested you need to convert the row for graphics, but I couldn't find the option. ANY help or tips would be super appreciated. Thank you!
