We’re constantly told that procrastination is a bad habit. But in the sign industry, in some circumstances, it’s a good habit, in fact, an absolute necessity. We’re talking about laminating solvent-based ink prints.
The solvent in solvent-based inks penetrates the print media and carries the resins below the surface. The solvent then evaporates leaving the colour behind. It’s the evaporation process that requires you to wait about 24 hours before laminating. This solvent-escaping process is referred to as out-gassing.
Laminating before the out-gassing process is done will result in diminished optical clarity.
