Hi gang;
Awhile ago, Frank Corker took the time to put together a Photoshop Action script which closely mimics the Photograv process- without the cost.
Finally had a chance to do some comparisons on an apples-to-apples basis.
Baseline:
Used fairly high resolution pics and did a little prepwork on the master-set size and DPI, eliminated background, brightened image, put soft focus vignette around image.
1. Took master image and applied Frank's Gold method Action as instructed-lasered result on raw cherry board at P=100, S=70 on my 60 watt LaserPro Mercury.
2. Took master image, changed to Greyscale, input to Photograv with cherry parameter, autoprocess, and saved the engrave image. Lasered the image on raw cherry at same settings.
Results of two different pics are shown below. Not a lot of difference except Gold method result tends to be darker which can be corrected by brightening the master more or raising lasersped/lower power.
All in all, a pretty acceptable result for a push-one- button process.
Thanks Frank and Rodne
Best regards;
George
