I use Photoshop to convert images to halftone bitmaps for silkscreening, and have come across a new problem. I have separated my three grayscale layers, and converted the first layer (a scanned B+W image) as I normally do, without any problems.
That is: Image>Mode>Bitmap / Halftone, 600 dpi / 47 lpi, 45 degree angle.
I then try to do the same thing with the other two layers (objects drawn with the pen tool in Photoshop in black with no background). But the halftone doesn't work. When I try, the watch appears while Photoshop works, then there are the bodies on a white background. The black drawings continue to be solid as before only with somewhat pixelated edges. I have scoured the internet and haven't been able to find a relevant thread.
Any help would be much appreciated!
