I’ve seen on a couple of posts the Unmask Sharpen filter used. Personally I feel that is a useless filter.
Here is a very quick, easy and effective way to sharpen your pictures. It works especially well with photos taken from your phone that look great (on your phone) but when uploaded to your computer screen just aren’t as sharp as you thought.
This should work great for bringing out details for raster engraving.
Open you picture in Photoshop.
Next, make a duplicate of your photo. It should be above the original.
Then select “Filter”, “Other”, “High Pass”
You will have the High Pass filter adjustment screen open.
You do NOT need to adjust the Radius very much. Generally between 2 and 5.
Next, select Blending Options and choose “Overlay”
You should see a much sharper image with more detail.
I used a higher setting on the radius than I normally would so that the detail would be more visible.

Hope this helps fellow forgers!!
