I am in the look for some information about a banding problem that I have got with my laser. I own a 2005 VyTek 65W MLT4469 coming with a 1.5 inch lens a long with the latest Corel Draw, PhotoShop and PhotoGrav.
The laser is only used for granite and marble engraving. Well, my problem here is that the laser is banding all through the whole image on the Y-axis. At first, I tried rotating the image at an angle of 90 degrees. However, the banding remained on the Y-axis. I kept trying using different laser settings but there was positive change.
Eventually I decided a file supplied by VyTek with the laser in order to see whether I was doing something wrong. With the VyTek, I got a perfect image, with no banding; an image as clear as crisp. When I tried my own image once more, banding would appear all over again... Currently, I run marble and have realized that banding surely shows up more on marble as compared to the granite.
Some banding is noticeable in granite also. My question therefore is, “why do the VyTek supplied image come out clearly while mine does not”? Am I doing something wrong in PhotoShop and PhotoGrav? And lastly, does a cheapo scanner cause issues to do with Banding?
You advice or suggestions will be of great help. Thanks in advance
