4 bay "Day 2" Hobby Garage in WIP: Dioramas Posted April 15, 2020 That's why I splurged on the decal printing package from MicroMark. It came with at white cartridge for the laser printer that you can swap out with the black cartridge. It's a little tedious, but you can run the paper though the first time with the images converted to all "black"... which prints white if the cartridges are swapped. Then, run the page through again and print the 4 color process. Works pretty good but the registration is a little squirlly on the really small decals.
