I have Photoshop CS5.5 with Suitcase Fusion 15.0.5. When I use any kind of typeface in a Photoshop file it appears jagged. When I rasterized the type, the edges are still jagged. It does display the correct font and not defaulting to a generic one. It is just that the curved edges are bad.
I am to figure out if this is a Photoshop or Suitcase issue. I have reinstalled the suitcase plugin, no change. Reset Photoshop to it's defaults. My other apps (e.g. Adobe, Apple and Microsoft), the fonts look great.
What's the ppi resolution of your files? What type of file format?
Once rasterized, text in Photoshop is no longer vector. Unless you have a very high ppi resolution, text is bound to appear jagged.
Photoshop is not the ideal application for text.
It's a PSD file at 300 ppi, 5" x 7", CMYK. I am not using body text. Just a one word headline that I was planning on adding effects to later. The type seems more jagged than normal.
You could have a bad or corrupted font or font cache.
Strange that you're working on a 5"x7" CMYK file. If you're going to be printing on in inkjet printer, as suggested by the file format, you should stay in RGB. Of course, the color space has nothing to do with your jagged type, it's just my curiosity.
