Create a layer and give it a background color of your choice and name it bg layer
Write a line of text and give it a dark(ish) color and name it txt
Copy txt layer and drag the copy below your original txt layer and name it letterpress
Give letterpress layer a color that is significantly lighter than your bg layer and push it down by 1 pixel so that it shows (you can additionally push it to the left or right by 1 pixel for a stronger letterpress effect)
Select your txt layer and go to Blending Options, check “inner Shadow” with the following settings:
Blend Mode: Multiply (color should be black)
Opacity: 75% (or something similar)
Angle: 120°
Distance: 0 px
Choke: 0 %
Size: 5 px
Of course you can play around with the settings, but that is the general way you can get the effect you’re looking for.
Create a new layer (File > New) in Photoshop, then either use the bg layer that is already there or create one on top of it and name it bg.
In FireWorks, the process is quite similar:
Create new canvas, give it a background color
Write your text and name the text layer “txt”
Duplicate “txt” layer, name it “letterpress” and drag it below your “txt” layer and give this layer a color that is lighter than your canvas/document background and move it 1px down and optionally 1px to the left or right so that it shows through
Select your original “txt” layer, then go to your properties panel and click on add filter, select Shadow & Glow > Inner Shadow
Settings for Inner Shadow:
Distance (left, right, top, bottom axis): 0;
Opacity: 75%;
Background: Black;
Blur: 2;
Angle: 120°;
That should give you the same results as with the Photoshop approach.
