I OWN A 42″ WIDE DESIGNJET PRINTER 

My Black does not fade, the rest of my inks fade in about 6 months.  I print on Mylar and spray it with lacquer for your out door needs.  It needs to be on a white board. I print on draft paper – Photos on draft paper and then I have Photo Matte paper for photo quality large format printing. 

I have a $30 Minimum. Prices for printing are for files that are already sized right. I charge a $40/HR layout fee for text with photos.

I use a 40″ x 60″ Vacuum press, and I charge a mounting fee at .20 per united inch so a 16 x 20 mount will cost $14.40 if you supply the board. 

The Mylar works great for backlight signs and must be painted white on the back,  I make custom solar backlight signs and charge a 40/hr fabrication fee plus materials.
