I have been a secret follower for awhile now and learning all I can about c/p framing. I have a small frame shop in my home I started about 18 months ago and have been very busy ever since. I try to maintain all the standards in c/p framing ( uv glass "acid free" papers and foamcore...yes I remember the topic on "acid free") . I have a customer with 2 signed hockey jerseys (Mario Lemeiux's Team Canada jersey and an Ottawa Senator Jersey signed by all the players). He chose to shadow box the jerseys identically using Bainbridge 4179 as the base and 4165 for the vertical supports. The plan is to make a foamcore insert to put in the jersey, then stitch everything to the fabric mat 4179. My question is, Is there any chance that the strong red color could "bleed"? My thanks to anyone who can help me. This is a great site and I use the archive all the time. I feel assured I am giving my customers the best up to date info I can.
