Explain to them you are a sign shop and you need POS samples of their materials in order to sell more of their products and educate your clients as to their many option of UNITED products. They will send you a FOAM CORE PANEL kit. It has samples of all their media in 8.5x11
They have:
Ultra Board - similiar to what people call gator board - plastic face
Ultra Mount - paper faced poly coated - semi rigid
Ultra Core - paper faced clay coated - softer - more spongy
Ultra Plus - very rigid and has a thick pvc face - heavy duty
Ultra Aluminum - foam board with aluminum face
Ultra White DP - similiar to ultra mount - but this is for DP direct print - coated for flatbed use.
We use ultramount and ultraboard. ultracore is a bit spongy and tends to bend on larger 24x36 pieces. if the job is a small 8.5x11 pieces then you could get away with ultracore and save some money if it is a large qty job with small pieces.
hope that's helpful clearing up the differences. I just had to go over it with all the sales staff here. I still get order requests from them with "mount to gatorboard" when they really mean ultraboard.
for sure get a kit, put it on the front counter and clients can choose the board they like.
