Bill,
The decals are NOT made on a dot matrix printer. I use an Alps printer which uses a dye sublimation process to transfer the wax-like ink from the cartridge to the decal paper. The printer uses Cyan (blue), Magenta (Red), Yellow and black ribbons to create the colors on the sheet by applying different densities of the ink to make different colors. One color the printer has problems with is green. Most printers mix yellow and blue inks together to make green. However, the alps puts down a layer of blue and yellow dots in a supposedly random pattern. The pattern isn't random and gives the "dot matrix" effect. Unfortunately, there are very few ways to crrect this without massive amounts of effort, so I'm willing to live with this.
The "faint" white is due to the fact that multiple layers of white flake off very easily when color layers are applied, so for everyone's sanity, I only print one layer. Personally, I find that the thinner layer looks better and isn't as stark against the model. Just a couple of things to clear up any confusion.
Regards,
Georg
