Why the laser etched picture is too light inside crystal?

When your received your order from the “photo crystal” vendor, you find sometimes that the image was too “light” or “vague” inside. What caused the problem?

The first thing I would do is to go back to your desk and check the image quality that you sent to photo crystal vendor. 90% of the times you would find out the image may not be “clear” at the first place. Meaning the resolution is too small ( less than 100dpi)

If the image looks all good, the next step is to check with vendor. It may cause either by not having enough “points” for the image during image converting process (from your normal jpg or tiff file to machine readable format), or by weak power of laser beam to blast “dots” inside glass. The picture inside crystal that you see, is actually consisted of millions of “point”, or laser blasted dot, that created by laser engraving machine. If number of the points is less than needed to represent the clear, it will be too “light”. If the laser power is not strong enough to blast enough points, it will create a “weak” image too.
