Dear All,
From my sourcing, I know that 1pt = 0.002 gram. However according to my job (as an offset printer supplier), it doesn't make any sense to me, because it is too lightly for a pc of paperboard. They asked me for 18pt which means only 0,036gram/pc with size 109cm x 79cm (too thin I think) and I cannot ask my suppliers for this material.
Any Comment or info would be helpful for me. Thank you in advance.
