You might reduce your panel size, cut it in half and rotate to better utilize your edge clamping/board supports. Tape off your current stencil and see if it improves the print. A new stencil and a little extra handling may be cheaper than tooling.

For laser marking you don�t require as powerful lasers then for cutting. A 20 Watt laser diode does already a good job. Because of the safety requirements the laser operates in an enclosure, which means more $$$ if you want to use the laser in line

Without seeing a picture, my first instinct would be first and foremost some fixturing that provides full support for your print process. After that, since you are citing bow and twist, consider that the fixturing might as well travel through the ov

Here's an idea; buy a pcb conveyor and design a simple label applicator to mount to it. Maybe replace the logic with your own or replace the PLC in the conveyor with your own solution. Shouldn't be much more than a few sensors and and a stepper motor

Manufacturers who have to mark barcodes onto PCB's without secondary application of pressure sensitive labels can etch it on, screen it on, inkjet it on, use laser marking, or a combination of those. Using a laser marker to write a code into a label
