Why does a half-tone image appear so light on a silver lacquer disc?
This is due to the lack of contrast. The disc is about 20% darker then a white sheet of paper, therefore the picture appears flat. The increased reflectivity of the disc can also affect the appearance of half-tone printing. If this is a concern to you, but you still wish to use a silver lacquer disc, consider a white flood or a clear coat matte flood prior to printing your job.
