I am designing a 4x6 postcard. It consists of 2 blocks of text (headline and descriptor line) on top of a photo that takes up the entire background. It will be printed by a professional digital printer.
It is currently laid out in Photoshop as a 300 dpi CMYK file. I'm wondering if I can just save as Photoshop PDF and send that to the printer. Or will I get better/different results by doing the following?
- save the photograph as a TIFF
- Place TIFF in InDesign
- Re-create the text in InDesign
- Save (or export) as PDF from InDesign
If the end result is the same for both quality-wise, should the Photoshop file be flattened and type layers rasterized before saving as PDF? or again, will that not have any effect on the final product?
And final question: would any of this be different if it were being printed on an offset press?
