Hi ALL
I’ve been engraving peoples’ personal photographs for years; have suddenly run into a glitch!
After Photo-shopping a colorized picture ‘way I want it, I’ve typically turned it into a grey-scale bitmap. (8 bits?) - so that my PhotoGrav software would recognize it.
I read somewhere on SMC, ‘while back, the suggestion of converting photos to “black & white”, instead of grey-scale - which, then, seems to allow for 16, or 32, bits. (I believe?) In choosing ‘black & white’, photos seemed to engrave much nicer; clearer - mostly, on my Alder wood plaques.
Now, I’m engraving a photo on solid black granite. Have placed the (dog’s) photo on a black background - necessary when using my PhotoGrav “granite setting”. (BTW: I’m using CorelDraw X5.)
Appears the photo will engrave nicely, but surrounding the photo, I’m seeing horizontal lines of very tiny “dots” repeating throughout the black background! Imagine it’s something simple I’m doing wrong. What do I need to adjust, or do in order to eliminate those dotted lines? Help!
Thanks in advance! and have 'great day!
