Hi, I have recently got a Gaggia Classic Pro. So I am quite new to espresso. After I pull my espresso shot, the grounded coffee puck has imprints of shower screen (photo attached)

Is this normal? If not, how do I solve this?

I am filling it up with 18 grams of pre ground coffee (commercial espresso fine grind) in a pressurized basked.

    It’s not supposed to touch the shower screen. Mine does sometimes, too. Try decreasing the dose. Remember that light roasts weigh more than dark roasts per volume unit, so 18g of a dark roast is higher volume than 18g of light roast.

    While not specific to your basket, it illustrates the differences.
