I see JEI have the Chromatic Compound receipt that using 4 Magenta Paint Ball and packing by Mechanical Press in Ver 1.2.

But in game this receipt cannot work, There's only can 1 paint ball inside the Basin at same time.


I don't want to use Mechanical Crafter to do this if can because it was too bulky, so may I know how to fix this?

we used the crafter, it's not that much more bulky than all the things you'd need for the basin + press. We did have the same basin issue you did. anyway, assuming you put the crafter above the belt you feed in the balls with, you get the whole setup in a 2x2x3 prism, including the belt. I think that's the smallest I could make a press, if the recipe worked.
