Feel free to come by and pick up a sample printed from your desired output device. We calibrate our film recorders often to assure constant color from slide to slide, but over time the camera does tend to drift from slightly lighter to slightly darker slides. Also, keep in mind that slight changes in darkroom chemistry can produce color shifts. This is a normal occurrence in the industry, but we try to keep it to a minimum. Each printer prints colors differently.
Every monitor displays colors differently.
The goal of matching the color on your monitor to our printers is presently beyond our abilities. The current state of color matching technology either rests in the hands of the artists or with very expensive equipment. Color Management is advancing all the time.
