Quoted from Pimp77:

It looks like the original had frosted inserts there so that might explain it!

Quoted from pintechev:

Would you swap a playfield because a few of the insert lettering were hard to read?

Quoted from pintechev:

A great question for CGC.

Quoted from IndianaPwns:

I feel a bit bad for them as they're going to have to take a hit righting the obvious QC issue here. And it is obvious people - I've asked my friends to read the inserts from standing position and got responses like "Duck of Barbie".
The solution has to be legitimate. If they offer stickers or discounts saying "It's the brightness of the LED's" - I'll go ballistic.
You don't let playfields with inserts you can hardly read leave your factory.
In not out for blood, not at all, I just want a complete product. The game freaking rocks other than this issue.

Quoted from boustrophedonic:

I don't see how they can make any sort of grandiose gesture on this issue. How does one prove if they have faded inserts or not? What does it even mean to have faded inserts? How do you measure it?
Because it's an ill-defined problem, whatever course of action they choose, they have to be prepared to do it 1000 times. I seriously doubt they're willing to send out 1000 playfields.

Quoted from boustrophedonic:

What defect? How do you measure it? Here's are 2 pictures of my machine in single lamp test mode. The insert with the light on looks faded when the flash is off. Turn the flash on, it looks ok. Do I have an issue? Or not?
