My second attempt at this blog, as my phones blogger app swallowed the first attempt!
If you've read back over my blog, you'll know I am a big fan of decals on my 15mm mini's. As much as painting and the various painting techniques have been something I've worked on during this project, I've also developed my technical modelling skills.
One issue I have had when using decals is one such technical issue. Some of my models have a 'shiny' area around the decal I have applied, and despite many coats of matt varnish it just will not go away.
Here's an example.
Having done a little research to try and find a cure for this, I came across the actual cause.
It seems that when applying a decal to a painted surface, the paint makes the surface of the model grainy on a microscopic level. When the decal is applied onto this, it creates microscopic air bubbles. These bubbles reflect light, causing something called 'silvering'.
It seems that the way to avoid this is to make sure you put a layer of varnish down before the decal. The varnish provides a microscopically smoother surface which prevents the air bubbles forming. There are also some decal solutions that I am going to pick up (Vallejo make some called Decal Fix and Decal Medium). The Decal Medium prevents air bubbles forming, but I think I will also be making sure I do no more highlighting after the matt varnish!
