Difference lightscribe 1.2 on CD-R and DVD+R (Verbatims)?



Hi I purchased Verbatim CD-R’s Lightscribe 1.2 and Verbatims DVD+R 16x Lightscribe 1.2 colour (5 different coloured lightscribe discs in slimline jewel cases wrapped in shrink wrap) and the strange thing is that it looks like the same test image I burned on the CD-R and on the DVD+R (the colour resembling the plain gold CD-R the most) looks much fuzzier on the DVD+R.

Is this normal and why is this ?

I used the exact same software and picture and settings.
