Another vote for 3M. SCPM-3 since 'bout 1995 and thought I never use another brand until another shop in Toronto printed a large job for me and ran out of the 3M I requested. They use GXP900 (MainTape) and it's the same as 3M's but maybe a li'l better (thicker). I'm impressed so to speak. I just received a 54" and a 30" rolls for my big prints and can't wait to use it. I'm wearing glasses and once, with cheap paper I used in my first years in business, the paper just... well, you got the picture. It cost me near $350 to have my prescription replaced (new frame by the same occasion) so after that episode, I was shopping for PREMIUM THICK application tape. 3M SCPM-3 was the obsvious choice so I always bought that brand. Thicker stuff also means less chances to mess at installation step.
