I'm not going to swear it, but I'm pretty confident the following is true regarding the Black Triangle (actually, the first point is set in stone): It's not the "pressing" per se that matters when it comes to CD vs other CD issues, but whether or not the same master was used to produce the CD's in comparison to other issues. It's highly unlikely that Black Triangle would use a different master than the other CD releases from the same time. It is true though, that the old masters are "better" than the remasters, and Black Triangle are prominent.
So as long as it uses the same source material, it doesn't matter if it's Black Triangle, or say, a European release that stems from the same master. The source of confusion though, stems from the vinyl transition to CD. The quality of the vinyl reproductive format depends on a gazillion of things and how it was pressed (the quality of the material used for the vinyl, the engraving process etc etc - Nowadays, vinyls use a digital source anyway in 99 cases out of a hundred rather than tape machines as back in the day - Although you make a vinyl specific digital master, that is used as the source, so it's not simply a CD-porting to vinyl. Wanted to clarify that), thus what "pressing" is of importance.
(slightly later addition, to clarify): It's inherit to the CD format that each copy is identical to its source, so the Black Triangle is just as good as other releases that stem from the same master. Quality of the CD itself (how well made the actual disc is) is not as important as with vinyl.
