Ahh...the big problem with the current batch of printer is they do not print white. Printers assume you are printing on white paper and use the paper color for white. So a brighter paper will give a brighter prints and brighter colors but that doesn't help us people who make decals. Only Alps printers were able, through a white thermal wax ink cartridge, to print white. Alps aren’t sold in the US anymore. Even Alps printers were not perfect; they were known to make banding in printed areas.
There are ways around that white background problem but it does take a couple of extra steps.
One way is to get white background decal paper but after printing on the white sheet you have to carefully cut around the decal so none of the white edges bleed outside the decal. Then a black marker or pencil is run around the edge to prevent the white edge from showing up. Then apply on the model.
Another way is to print two decals, cut them both out and paint one white. Then apply the white decal on the model. When the white decal is dry follow up with the unpainted decal, registering it on top of the first one. The white will show through the clear areas.
Another way is similar to the second way. Print and cut two decals and apply the first decal. When the first decal is dry you airbrush the white areas on the applied decal. Then you register the second decal on top of the first one.
Another way would be to get someone who has an Alps printer to print your decals and let him use up his supply…but that would be cheating.
I would consider buying an Alps at Ebay but I don’t know how long the ink suppliers will keep the inks in stock and I don’t know if the inks have an “expiration date.”
I’m not an expert. Anyone else have suggestions for getting white on homemade decals?
