Decals for the interior glass in a building: meeting-room fronts, glass partitions, reception screens, internal doors and display cases. Room names and numbers, department branding, the manifestation dots and bands that stop people walking into a glass door, wayfinding, and messaging that changes with the campaign.

Three films, and the choice is really about how much glass you want to see. White Spot On is opaque white, so the artwork reads as a solid printed shape sitting on the glass. Clear Spot On is clear — only the ink shows. Optically Clear Vinyl is the clearest of the three, for when you want the carrier film to disappear entirely and leave nothing but the artwork. All three are self-adhesive printed vinyls, not etched or sandblasted glass.

Interior glass usually gets looked at from both sides, which is why Reverse Printed is worth knowing about here. The artwork is mirrored so it can be applied to the far face of the glass and still read correctly from the side that matters. That puts the glass in front of the ink: the graphic cannot be picked at by passing hands, and the surface stays easy to clean. Tell us which face you are applying to and we will print it the right way round.

Printed White adds a white ink layer under the colours on the clear films. Without it, colours over clear film are see-through and will pick up whatever is behind the glass; with it, they stay solid. It is also what lets a design have both a solid element and a genuinely clear window in the same decal.

Lamination in gloss, matte, optically clear, dry erase or anti-graffiti, and contour cut for room-name plaques, shaped logos, dot patterns and anything that is not a rectangle. Order by entering the width and height of the finished decal. What arrives is the printed decal itself, cut to the size you ordered on its backing sheet and ready to apply; installation is not included.

Two honest cautions. This is an interior product — for anything applied to the outside face of a street-facing window, or otherwise exposed to weather, order Exterior Window Decals, which carries the films chosen for that job. And on the clear films, whatever sits behind the glass shows through your artwork: a busy corridor or a bright window behind a delicate design will compete with it. If the background is busy, either pick the white film or use Printed White behind the type.
