With any stencil or silk screen the lighter colours go down first.. so in your case - black will be last. You might want to allow some overlap on the black ( or underlap on the orange).. the registration on the stencils was made to eliminate human error.. what you see as the final product is not always what was put down - the cabinets were done quickly and without too much input to align.
If you want me to make you stencils i will - just email me square on pics of cabinet, front and header front and sides - also dimensions to make sure im making to correct size ( i always double check) and ill vectorise your machine and supply stencils to you.
PM me for more details
