Easy mistake to make and you're not the first.
One thing to remember is that after you've dressed the timber nice and square, don't lie it down on the bench, or it will cup again. Stand it on edge so that the air circulates around it. That way you'll minimise the chances of it cupping. Also, try to plan your work so that there isn't a long time between dressing the timber and gluing up.

That though had crossed my mind, but like many I "assumed" that the boards were flat. As they say "assume = ass out of U & me." We all learn from "others mistakes."
As I said before the good operators find their mistakes before anyone else does. So if you find it first it isn't a mistake???Mobyturns

Great advice on material handling. Also a good idea to keep away from direct sunlight and strong sources of UV light.
Board movement is also an issue I face regularly when laminating up boards / stock to cut components for inlay banding! The boards are a sandwich of veneers & thin boards and may not be a symmetrical glue up. Anyone who veneers a board will also face the same issues. It is important to let the board steadily reach or re-stabilize to equilibrium moisture content - EMC.
I want my glue-ups to stay flat before, while and after I cut the parts. Otherwise I face the same issues as the OP's problem. After the initial clamp up between cauls and the glue set I remove the plastic (or grease proof paper) etc and place the laminated board between MDF cauls under reduced clamp pressure while the glue fully cures. I then inspect the boards and return them between the cauls with only sufficient clamp pressure to prevent warping / cupping as the laminated board reaches near EMC over a week or so. Prevents a lot of hassles.Mobyturns

Don't worry too much. I and many other are learning what not to do and how to test things in order to avoid a similar post later on.
you are making me much smarter so thanks.

Agree Elan. I have a quality crosscut blade in my mitre saw & it produced terrible cuts, off the line & wonky. Specialty Saws in Croydon weaved their magic & the blade is now spot on!
