If you have access to a magnifying glass or a gem dealers loupe of at least 12x, check the cloudy spots to see what they "look like".....if the areas look like a ga-zillion, small water droplets or even microscopic air bubbles, it could very well be the result of an area of the decal that was not properly "activated" with the rolling or burnishing procedure. Since the vinyl carrier of the decal is clear, the only thing that could cause a cloudy appearance would be the adhesive layer or something that has been trapped underneath the decal during the application. If you do not use a piece of clear packaging tape as "transfer film" over the decal, any contact with the adhesive side will definitely leave marks that will look cloudy at the area touched if they are not removed prior to rolling or burnishing.
Also the printing resolution of the 270 is fine, but it is much less than the 320 and therefore has the potential to show the edges of any image to appear "not as sharp" as it should be.
The 3M product I use will have that same appearance if the adhesive layer is not properly burnished or rolled and a spot is missed - and it would have the same end result whether placed over a section of epoxied blank or not. Rolling or burnishing any decal should be done from the centers of the decal, going away from the center in each direction or you will slightly trap areas of adhesive that can't get properly flattened & activated. The adhesive layer on the 3M media is somewhat more robust than that on the Sun 270 as I have checked it on some decal samples from the sales rep that is supplying the rod builders with the Sun equipment. I also use a similar piece of label equipment at work that is made by the Sun people but under a different name. I even bought some tapes from him for work as I like to support those that are helping us promote the art of rod building.
All of this typing may be OK but until I see a well focused image of the issue, a proper diagnosis may not be possible.
