And they were all wrong, too.I've read many threads in multiple forums, and videos, where people called the sticker's placement an inlay.
An adhesive label (often laminated) is just that -- a base material (paper or vinyl), sometimes covered with a protective plastic laminate, with an adhesive glue on the back, which adheres it to the chip surface (usually in a recessed area) when it is applied to the surface of the otherwise finished chip. It is essentially a sticker, and unless using a UV-cured adhesive, relatively easy to remove afterwards.
An inlay is different, in terms of how it is affixed to the chip. The base material (paper, linen, or vinyl) is also usually covered with a protective laminate, but the inlay itself is actually pressed into the chip during the compression manufacturing step, using extremely high pressure and heat. Depending on the specific compression mold being used, the finished inlay may be recessed, or it may be flush with the rest of the chip surface area. It also takes on the surface characteristics of the specific mold, meaning that it may end up with a linen or crosshatched surface finish, or it may end up with a smooth finish -- all dependent upon the mold, not the inlay itself (although matte finish vs glossy is usually a function of the protective laminate material). Because it is actually inlaid into the base chip material (hence the name), removing an inlay is usually extremely difficult, and will often end up destroying the base chip in the process unless done with extreme care.
To summarize:
All plastic chips (including china clays) with artwork have adhesive labels which are applied after the chip manufacturing process is completed (usually injection-molded).
All high-end compression molded chips have inlays which are pressed into the chip during the manufacturing process -- unless the chips are produced as blanks (which have no inlay, but can be later hot-stamped). Some blank high-end chips have a deep enough recess to take a thin label, but others do not -- it is all dependent on the mold characteristics.
And for reference, ceramic chips use a dye-sublimation method to apply ink directly onto/into the surface and rolling edge of a blank chip.
