My thoughts . . .
I wouldn’t try to create a halftone to reproduce it. It’s a beatiful engraving, so I think better to treat it as though it were line art, so that when printed it isn’t converted to a screened image at all.
I found this helpful blog post which describes the basic technique: Line Art – the One and Only True Bitmap format. As it stands, it doesn’t really work well with your example image because it’s not really high enough resolution, but I think you could tweak it a bit to get a decent enough result.
-
Convert to greyscale
-
Rescale the image by doubling its pixel dimensions. If the scan was 300ppi, this will effectively bring it up to 600ppi which should help keep pixelization to a minimum, or larger if you’d prefer. Alternatively if possible, rescanning it at a higher resolution would be the best.
-
Convert to a Smart Object
-
Apply Unsharp Mask to help retain the detail
-
Apply a levels adjustment layer
- Apply a threshold adjustment layer
Tweak 4, 5 and 6 if necessary to try to keep maximum detail in shadows and highlights.
Before final output, convert to bitmap mode, and export as BMP. For peace of mind, request a proof before going to print.
Here’s the example, showing the unsharp mask settings. Note that I put the adjustment layers in a group so I could easily toggle them on/off to check with the original.
