Why have all dvd+r blue dye?

[Espen]

Just wonder why almost all writeable dvds has blu dye on the write area. Why is there for exampel no dvd+r with silver dye like the original dvds movies.

are you serious man?

dvd-r's and dvd+r's, any media recordable is "burned", not "pressed".

pressed is for retail cd/dvd discs. that's why they are silver

Greetings,

I was wonreding this a little while ago, but I did not have the nerve to post it...hehe.

I noticed CDs have Gold, Silver, blue, purple and reddish dye, but the DVDs +R and +R(W) I have have only purple(Sony, RITEK,etc) and light grey dye(Memorex). It seems the type +R or +RW does not have any relation with the color because I have some RW purple and some other light grey.

In any way, I figured out by reading many posts that the color has no quality associated to it (like the CDs, where the golds were the best) but the brand is what is important.

Thank you

Well I know dvd movies are pressed and so on, but my question was, why can't they do silver dye printable dvds?

Greetings,

I said in my post I have DVDs with light grey dye. Those are Maxwell +RW 4.7GB 4x.

Thank you

Maybe the chemichals in the dye mixtures just don not produce a silver color. The reason why different brands may have different color is just that they use different types of dye.

By the way since there is no dye in a pressed original, the silver you see is the reflective layer.
