Question: Do you burn the dvd or print on it first? Or it doesn't matter?
Document: This is the first Watershield Disc I have ever used.I was pleasantly suprised at the beautiful glossyfinish! They burn perfectly as I have come to expectfrom Taio Yuden!
I'm converting all my family vcr tapes to dvd and bought these dvd's so I could print the labels on them. They were absolutely great, I've used 50 with no problems at all. I'm using the Epson R200 and the ink seems to dry quickly, doesn't run when it's wet and doesn't scratch. I would definitely recommend these.
Most anyone can print on a cd.... but these make your discs look pro. The glossy finish is so much more impressive, when compared to the matte finish. My only dislike is that they are 16X speed. Some older dvd players don't recognize DVD media that is faster then 8X. Fortunately more and more people are upgrading their dvd players and the compatibility issue is becoming less of a concern.
Taiyo Yuden has the reputation of being a premiere blank disc manufacturer, and it is well deserved. I've never had one of their discs fail to burn.But the exciting thing about this particular disc is the glossy Watershield surface. Simply put, if you start with a quality, high-resolution image and print with a high-resolution consumer printer [I use an Epson R260], you will be amazed at the image that you'll see on the disc. It looks in every way completely professional.
Everyone perfect. I create very large slide shows with lots of transitions and slide styles. My shows always run perfectly and when I print the subject matter on that WaterShield surface they look very impressive too. I love these! They are better than anything else I've used, AND, I've NEVER burned a coaster using this product.
Don't think I've ever had a coaster and the high gloss finnish makes the graphics pop on the dvd. Highly recommend
an outstanding offering, but since you basically can't find a comparable dvd+r product (last i checked) why settle for anything less than taiyo yuden/jvc? i'm not saying it's flawless product, but it is more reliable than any other product that i have used; and that's saying something!
My wife bought this product and was ripped off. Only the top half of the stack (the first 25 discs) was DVDs. The rest were all CDs. When she tried to complain, they said that they did not accept complaints beyond 90 days after purchase. This is dishonest, and I do not recommend this vendor.
These are the premier waterproof DVD's. They have never failed a burn and always look like they were printed professionally.
But when I want to impress someone or when I want to give them the very best that is available to me, I ALWAYS burn to Taiyo Yuden Watershield.
Answer: You should burn it first.  You can go the other way but you'll need to be certain that it is completely dry before you burn it.  There is a possibility the graphics could smear if you don't.  Not likely but a possibility.
