Hey Alicia, for large print A1-A0 size I always go to Archprint,
it's 24 hours.. and originally only in Cyberjaya now they've another branch in Sunway geo..
so far so good, color is accurate af and plenty of materials to pick from.

You can try PrintExpert in Shah Alam as well, their printing shop is like a clinic and it's huge (hq),
used to go there for my large prints when ArchPrint doesn't exist yet. Tedious travel but worth it (I went to many shops around PJ and they are not as good) just my personal opinion!

You can search those keywords on google and their websites n contacts will pop out! Good luck!
