I wouldnt say their proof was correct. If thats a dark blue, it might as well just be black. What you sent has a navy, not black or close to it. To be fair to stahls, or anyone else printing digitally, hitting PMS is basically impossible. In our shop we have 3 different roland vinyl printers, a dye sub printer, 2 DTG's, assorted inkjets and lasers, etc and they all print the same art differently, sometimes extremely differently.That said, you aren't happy, what the print is obviously in need of tweaks, and it's less than $100 (it probably cost them next to nothing honestly). Hell, even our tiny shop would fix an error like this on a job this small without batting an eye.edit: In the future, you can get an "okay" idea of how a file will print by using photo paper on an inkjet and converting the file to cmyk before printing. It will mute the tones a bit and youll see color shifts that happen due to that color profile. Would probably have shown you the file you sent needed that blue to be lightened a bit to print properly. Again, not PMS accurate, but better.
I think their proof looks closer to the finished product than to your supplied art honestly.
the bull crap they laid down over a lowsey (lousy) $86.00 retail amount order.
