Going to try to get my recent piece printed at the professional printing service we have at work. I’m pretty sure I’m allowed to use them for personal stuff too…?
Approx. $8.00 for a 24x36 inch poster seems pretty dang good. The printer supports a max of 40 inch wide with unlimited length.
Now comes the fun part of converting to a CMYK profile as an afterthought. Krita only supports some useless CMYK profile that nobody uses, so I need to nag the printer guys to send me the .icc stuff for their printer.
