Generally, for brands like Ibanez which make a wide range of guitars at a wide range of price levels, they'll state if it's solid wood. E.g. 'solid spruce top'. If they say 'select spruce top' or just 'spruce top', it refers to laminated woods.
It's different for high-end guitars such as Martins, Taylors and Gibsons as they predominantly use solid woods, so unless otherwise stated (e.g. Martin's 'high-pressure laminate', or HPL, in their lowest-end models) , for these brands it's solid wood by default. Then again these high-end brands would also tend to be more specific as to the variety of wood, so they use terms like 'sitka spruce', 'engelmann spruce', 'western red cedar', 'koa', etc. These are solid woods by default.
