I go from Latex (At home) To Solvent (At work) And I hate it. I just dumped 4 liters of ink / cleaning solution out of the waste container at work. Lets say it's only 3 liters of ink... Thats about $400 down the drain. Nevermind the smell... How the heads dinged up and they want $4000 per head, so now all our prints are subpar... Tons of reasons people "Think" latex is better than solvent. I've been pushing and pushing for them to buy a Latex for a year.
There are issues. 90% Of the issues / Drawbacks are due to lack of experience, and just needing to get to know the machine. Think of when you just bought your first solvent... How many issues you needed to resolve. Latex is the same way... Its a similiar technology, but it's used in a different way - As with all new techs, there is a learning curve.
Latex does still have it's downsides, but the upsides far outweight Solvent upsides for me.
As for 10 oz banner... I print on it just fine. No headstrikes or nothing, I always print attached to the takeup reel, so maybe thats why. The only issue I have is the heat shrinks the Material... my 60" banners came out 59". Pretty big shrinkage... Of course it was the first time I was printing banner on the Latex though, so I didn't realize it can shrink, and that theres a compensation for it. An example of one of the "Drawbacks" thats a bit of a learning curve. An issue thats easily fixed, you just need to know how to fix it.
