Mottled coaster printing

[justme]

Hi,

Wondering if anyone can help...

When I print my coasters, especially dark colours...they have a tendancy to come out mottled (see attached picture). I am using a cheap swing press from BMS and am printing at 190 for 60 seconds.

Would really appreciate any guidance as to what needs adjusting!

All black is hard to do on coaster, try taking out the moisture by pressing it for 10 secs

Thank you so much, that - and adjusting temp to 200 seem to have done the trick

might be worth remembering to "mirror" the print as well, so it prints out the right way :rolleyes:

I think I have...made me log on to check the pic though!!

OK, so I got bolder after your help (thank you!) and thought I'd try a placemat. I have done pre-pressed this and I have pressed at 200 for 75 seconds. The edges are great but the middle is faded. What do you think I need to adjust for this? Would be grateful for any help!

Pressure is not even on the press, so you have a bit of a soft spot in the middle, by the looks of it

You need to turn the pressure up so it is nice and firm.
