Front Adhesive Vinyl in Los Angeles: Window Graphics That Install From the Inside

Almost every shop owner who calls us about window graphics is really asking one question: how do I put my logo on the glass and keep it there? Los Angeles is hard on anything stuck to the outside of a storefront. Sun, dust off the boulevard, a pressure washer once a month, someone's fingernail at the corner, the occasional tagger. Front adhesive vinyl is the answer to that problem. The adhesive sits on the printed side of the film, so the graphic goes on the inside of the window facing out, and the glass itself becomes a permanent layer of protection over your artwork. Here is how it works, what it costs, and the handful of situations where it is the wrong choice.

What "front adhesive" actually means

Ordinary adhesive vinyl is printed on the front and glued on the back. You stick it to a wall or to the outside of a window and you look straight at the ink. Front adhesive vinyl reverses that: the adhesive is on the face, on top of the printing, so you press the printed side against the glass and view it through the pane. Printers call this second-surface application, and it is why the artwork has to be produced as a mirror image. Get that wrong and you have a perfectly good graphic that reads backwards to everybody on the sidewalk.

Our front adhesive vinyl starts at $62.54 and prints on clear matte vinyl. The matte finish matters more than people expect on a west-facing window in the Valley — a gloss film behind glass gives you two reflective surfaces stacked on top of each other, and at four in the afternoon on Lankershim the graphic disappears into the glare. Matte kills the second reflection.

The white ink is doing most of the work

A window has daylight behind it. If we printed your color artwork on clear film and stuck it to the glass, the sun would come through the back of the ink and wash it out — dark colors would go muddy and anything white in the design would simply not exist, because there is no white ink in a normal four-color print. White is just the absence of ink, and on clear film the absence of ink is a hole.

So we print a white underbase: a solid layer of white ink laid down behind the color, in the exact shape of the artwork. That gives every color something opaque to sit against, and it is what makes a logo on a window read as saturated from across the street instead of as a ghost. On the configurator that is the 5/0 option — four colors plus white, one side. There is also a 5/5 build that prints artwork on both faces, which is worth thinking about for a glass office door where the people inside the suite look at the same door all day and would otherwise see the blank back of the film.

Sizes, shapes and what moves the price

Stock sizes run 24 x 24, 24 x 36 and 24 x 48, plus 36 x 36. Custom sizes go from 12 inches up to 48 wide and as tall as 240 inches, which covers a full-height door panel or a tall pillar of glass beside an entrance in one piece. Wider than 48 and the graphic gets tiled into panels with a seam, so if you are covering a big display window, tell us the pane dimensions and we will lay out where the seams land — usually hidden in a mullion or in a low-contrast area of the design rather than through the middle of the logo.

Shape is a separate choice: rectangle, circle, or a custom contour cut around your artwork. A circle costs a little more than a rectangle and a custom shape more than a circle, because both add plotter time and weeding. Turnaround is the other multiplier — five business days is the standard, with two-day and express options above it when a grand opening date has already been announced.

Preparing the file

Send vector art where you can — PDF, AI, EPS or SVG at final size, fonts converted to outlines. You do not need to mirror the file yourself; tell us it is going on the inside of the glass and we will handle the reverse and build the white layer. What we cannot fix after the fact is a low-resolution photo blown up to 36 inches, or a logo supplied as a 600-pixel JPEG off a website.

Two things to watch in the design itself. Thin strokes below roughly an eighth of an inch at final size are fragile during weeding and application, so hairline serifs and 1-point rules around a mark should be thickened or dropped. And remember the graphic is being read through about a quarter inch of glass from ten or twenty feet away — phone numbers and hours want to be bigger than they look on your screen. The usual layout for a door is a centred block at about 60 inches off the ground, name largest, hours and phone below.

Installing on the inside of the glass

The film arrives weeded and pre-masked with transfer tape holding every piece in position. Clean the inside of the glass with isopropyl alcohol rather than blue window cleaner — the surfactants in glass cleaner leave a film the adhesive will not bond through. Position with masking tape, tape a hinge across the middle, peel the liner from one half, squeegee from the centre outward, then repeat on the other side. Leave the transfer tape on for twenty minutes or so before peeling it back on itself at a sharp angle.

Working inside is genuinely easier than working outside: no wind, no sun cooking the glass, no ladder over a sidewalk. Surface temperature still matters — somewhere between 50°F and 90°F is the working range, and a west-facing pane in August is well above that by early afternoon even with the air conditioning on. Do it in the morning. On large panels, a light mist of water with a drop of dish soap buys repositioning time at the cost of waiting a day for full bond strength.

Where the inside of the glass is the wrong place

Three situations to check before you order. First, existing window film. If the glass already has aftermarket tint or security film on the interior, the vinyl is bonding to that film and not to glass, and when the graphic comes off it can take the tint with it. Second, dark artwork on tinted or double-pane glass absorbs heat between the layers, and heavy solid coverage in full sun is a known cause of thermal stress on some glass — for big dark blocks on a tinted window we would rather put the graphic on the exterior face and laminate it. Third, textured, frosted or wired glass gives the adhesive nothing flat to grab.

Also worth confirming before printing: many jurisdictions across Los Angeles County cap what percentage of a window's area signage may cover, and building and fire officials care about sight lines into the space. A coverage plan across several windows or several locations is the kind of thing our outdoor advertising and signs work covers, and permanent identification at the entrance falls under signage and front signs.

When you want something other than a window graphic

Front adhesive vinyl is fixed in place and only exists where there is glass. If the message changes daily — today's specials, a lunch menu, a sale — put it on the sidewalk instead: an A-frame sidewalk sign starts at $94.99 and takes swappable inserts. If you want your name to stand off a lobby or reception wall with visible depth and hardware, acrylic business signs start at $46.76 and mount on standoffs. And when the graphic has to live somewhere with no window at all, or you want a full printed panel you can unscrew and take to the next lease, acrylic printing from $90 does what the vinyl cannot.

We print and cut front adhesive window vinyl, frosted and clear films, sidewalk A-frames and acrylic panels at our shop at 8511 Lankershim Blvd in Sun Valley, for storefronts, offices, studios and clinics across the San Fernando Valley and greater Los Angeles. If your artwork is ready, pick your size, shape and quantity and order online. If you are not sure whether your glass is tinted, how big the lettering needs to be to read from the curb, or whether the graphic belongs inside or outside the window, call us at (818) 806-9006 or bring a photo of the storefront to the shop and we will work it out with you first.
