    A quick search should get you a million threads on this already.

    it all comes down to your needs and the tech support nearby. No point picking a printer that’s 1k cheaper if it costs an extra 2k just to get a guy out to look at it.

    there’s also UV nowadays. Again, depends what you need them for as they all have their own particular strengths and weaknesses.

    I don't think Latex is a good fit for Asia... My understanding about printing in Asia is mostly about hitting extremely oversaturated bright colors. Although the Latex is capable of this, it will be slower to achieve than the solvent machines.

    We just switched back from Latex to Epson Eco-solvent. We do graphics for emergency vehicles on 3M reflective material. The reasons we switched back was the fact that the latex ink covers up the reflectivity of the material and in order to hit vibrant reds we were having to run inks at 200% density with massive amounts of optimizer to prevent bleeding of the high density inks. This further complicated the issue of applying laminate as the laminate would not adhere well to the latex ink. HP's suggestion was to wait 24 hours after laminating before cutting which negates the whole reason we switched to latex, to have fast turnaround.

    You are battling our opinions, so why do you want to change your process, what do you think Latex will offer you?

    I am by no means a printer expert, but my understanding is that waiting before anything with latex doesn't do anything for you, since the ink cures with heat. I wonder why they would tell you to wait.

    I've had times my wonderful latex doesn't have even heat on the curing platen, and I've used a heat gun on low heat to "finish" the drying process, which worked. But I also let a print sit for weeks that wasn't fully dry off of the latex, and weeks later it was still oily.

    Odd.

    I believe the oiliness is the issue. It's front the optimizer being run so high and it just doesn't go away. The only reason we have to run so high is that our customers require a more intense red so the inks are super saturated.

    Agree, and letting the prints sit for 24 hours or 24 months I don't think will "dry" the oil/optimizer, the only thing that will is heat.

    The main advantage for latex printers is that the print is ready to use, laminate, or cut immediately after coming off the printer. There is no required drying or outgassing time.

    The disadvantage for latex printers is the print quality.

    Latex is approved for traffic signs... Which must meet certain standards of reflectivity. We print green blue and yellow all the time and have excellent reflectiveness.. much more than our solvent gave us.

    Perhaps you were laying down too much ink for reflective? We print at 6/8p and 100-120% ink and can hit a decent red. It's definately harder to dial in the correct settings to print nice colors on a latex... Especially reds, but it is doable!
