Hi ive been reading all comments on slate its something I want to do i have good success with coaster size 480 sec 190oc med pressure then i go a size up with same settings and I have a small issue when you look at the slate it looks good but when you tilt the slate under the light you can see small spots bits that seem dull like the gloss finish dull it's like the print did not transfer .
as i use bigger sizes do i need to increase the time? ie added the slate below although you cant see the issue on the photo,the sun rays are on the photo
