One of the biggest problems in this industry, in my opinion, is manufacturers selling people printers and telling them that it's turnkey out of the box. That sells printers but it's not as simple as they say. If you want to maximize your color gamut and print good blacks and reds, making a custom color profile and linearizing occasionally is the way you do it. They don't tell you that because it costs a lot of money for the equipment and training to be able to do it properly and, when every other manufacturer is marketing their printers as turnkey, it's a competitive disadvantage to do so.
