Got a call at 12:30 to come and supervise the application of the printouts of our design for the skin of the Lineadecor booth. By the time we arrived at 13:30, the workers had already applied the designs wrong and a bunch of the pieces were missing. When the errant pieces finally arrived an hour later, they were a totally different shade of blue. I was worried that I had not converted both of the files to CMYK, but it turned out that the printer had used two different machines that were not at all calibrated. We collected the rejected printouts and took them home, where we wallpapered part of our office.
