As the title says, I have only one 8x10 dimple bottom tray, which I purchased from a shop in Austria years ago. Unfortunately, they no longer carry them. I find Cesco trays better than AP / Kaiser / Paterson which are easily sourced locally. Thanks.
I sold my Paterson trays and replaced them with KD trays, now available only second-hand. They have raised ridges instead of valleys for the Paterson. And the Paterson trays had the center curving upwards, thus requiring a larger volume of liquid to ensure a minimum thickness.
Example of KD trays:
Still the best trays to my knowledge are made by Deville. Thick, rigid, and more expensive. The bottom has dimples. Maybe the same one you bought in Austria. I have a set in 24x30 format but cannot justify the cost of buying Devile for the other sizes 18x24 and 30x40.

Hi Bernard, I purchased the Cesco tray, not the Deville. The Deville I have is a large 20x24 tray, which I used a couple of times in the past for 20x24 printing (single tray processing method). I don't use it anymore as it's too cumbersome
