I've been lurking for a while now. Read all of the posts and have been very impressed with the knowledge and responses to questions. Excellent forum.
Now for my question. I have a LaserPro Mercury 25 watt laser. When I print (send something to the laser for engraving) there are several setting that must be input, i.e power, speed, miror, invert, mode (black& white,manual color fill, 3-D or stamp) and DPI and PPI. By default my DPI and PPI settings are 500 and Auto respectively. I can leave the PPI set on Auto or manually set it to 30 or 50 to 1500 PPI in 50 PPI increments and the DPI to 200,250.300,500,600 and 1000. Does anyone know what the actual PPI will be for a given DPI setting when set to Auto. My machine's manual is totally useless. The manufacturers site didn't shed any light on the subject to me. Have Googled quite a bit on the subject but found nothing specific. Tech support, DUH?
Logic tells me that a 300 DPI graphic should be lasered at 300 DPI and 300 PPI otherwise the machine would be required to do a lot of interpolation. I have tried different combinations of DPI and PPI settings with mixed results.
Is there a rule of thumb for these settings? Any comments or links on this subject will be greatly appreciated.
Thanks
