We have two Komori SP's and have recently been trying to print book covers on a Linen stock. I beleive it's called Linen Set. The paper thickness is .20mm but in order to make it look decent at all we have to squeeze it down to as low as .04mm. My questions are; Is this normal? Where we have impression cylinder jackets are we taking a risk of damaging them? Do you have any advice on this issue? Any advice or comments would be greatly appreciated. Thank you.
