Text is pixelated

Hi Emily, and congratulations on your big day.

Just to add, if the text is pixelated, something is set wrong.  If you load the file with the pixelated trext back into Photoshop, what is its size in pixels?  If things are right then the size should what Brad told you, as below.

Best practice is to leave the document fully layered, and not flattened.  This is especially important with the Text Layers.

Then save out to PDF using the High Quality Print preset.

Is the file coloured or B&W?  If coloured then you have colour space to think about.  I always asked the printer, but sRGB is safe.  Our @D Fosse is the man to tell you about that stuff.

Incidentally, if you save out to PDF with the preset I mentioned, you should be able to open it, and zoom in as far as you like without the text becoming even slightly pixelated.  

Good luck on you big day.

Type Layers can be output as Type content in pdf (if no faux style is applied). 

Could you please include the Layers Panel in the requested screenshot? 

Could you please post a screenshot showing how it appears in Photoshop at the 100% view level? It’s crucial to evaluate it at a 100% zoom level, which can be achieved using Ctrl/Cmd + 1.

The other thing to consider: if you are working with live-type in Photoshop, it imay look sharper than your intended export the more you zoom in. However, it will be rendered out in pixel form when exported at your final 300 ppi resolution, so especially on smaller type, you will see this when you zoom in on it.

The file is definitely not too large. at 24 x 36, your pixel dimensions are only 7200 x 10800, far below the limit.

If any of your formats still looks good (lile the TIFF) when viewed in Photsoshop, then something else is at play.

When you say uploading, where are you uploading to? To an online service? Perhaps they have a limit.

Where are you seeing it pixelated? In a supplied proof?
