UV light test - what should I look for?
Good call on the 365nm UV light, but keep an eye out for UV bleeds too — when the laminate gets hit, the glow should stop clean where the print is, not smear across the edges. And don't sleep on the ghost image. Hold it under UV at an angle, because a weak one usually means the whole thing's rushed. Photos don't really show it though, you kinda have to have it in hand to judge.
This is a solid starting point, but honestly the UV test is where I separate the good from the fantastic. I always hit it with a 365nm UV light first thing—looking for UV bleeds around the edges and the state seal is a dead giveaway. If that passes, I check the tactile laser engraving on the DOB and the ghost image; cheap ones skip both or make them look flat. And for the love of anything, run it through a PDF417 scanner before you even look at holograms, because if it don't scan, nothing else matters.
Yeah, after going through a bunch of IDs from different places, I've kind of put together my own little checklist for checking quality. Figured I'd share what I look for and then get into the stuff I've learned beyond the basics.
First thing I check – edges and lamination. It's your first line of defense. If the edge seal is uneven, you'll see tiny bubbles or a slight ridge where the laminate ends. I run my fingernail along the edge – if it catches at all, that's a bad sign. Also, hold it up to a light and tilt it – real cards have a seamless bond between layers, not a visible glue line. The lamination should be consistent thickness across the whole card, no waviness.
UV features under blacklight – that's honestly the whole reason I started this thread. You should check more than just that it glows. Look at the fine lines in the UV overlay – on real ones, those lines are crisp, not blurry or bleeding into each other. Color temperature matters too – some UV inks lean too purple or too blue compared to a reference. And make sure the UV pattern aligns with the card design – if the UV rose or state seal is shifted even a millimeter, that's a dead giveaway.
Color comparison to real examples is huge, but don't just eyeball it. Take a photo under the same lighting and compare side by side on a screen. Pay attention to the background gradients and the portrait color balance. Some fakes have a yellow tint or the blacks look too rich. Also check microprint under magnification – real IDs have tiny text that's crisp, not smudged.
Flexibility test – yeah, that's a good one. Real polycarbonate or teflar cards have a specific snap when you bend them. Too floppy and it's PVC, too stiff and it's some cheap laminate. I bend it to about 45 degrees and see if it returns flat without any crease marks. Also try twisting – a real ID will have some torsional rigidity while still being flexible.
Now for the stuff I think should definitely be on your list: check the hologram overlay construction. Look at the hologram itself – on good ones, the OVI (optically variable ink) shifts color smoothly when you tilt. There should be a ghost image in the laminate – that's the smaller, faded version of your photo that's embedded in the overlay. Check its clarity – if it's too faint or completely missing, that's a red flag. The ghost image should be in register with the main photo, not shifted.
Perforation pattern quality is another big one. Some states use tiny holes to form the birthdate or other data. Shine a bright light through the card – real perforations are clean circles with no ragged edges. Fakes sometimes just print them on the surface or the holes are uneven. Also check the alignment – perforations should line up perfectly with the printed text.
UV detail accuracy – I've seen a lot of IDs where the UV pattern is simplified or missing fine elements like state outlines or small text. Under a UV lamp, zoom in with a loupe. Real UV prints have sharp edges and the exact same design as the visible version, just in UV-reactive ink. Some fakes use a generic UV pattern that doesn't match the state.
And scanner test results – this is the final check. Run it through a basic ID scanner app or a bar code reader. The PDF417 barcode should decode to the same data that's printed on the front. Check the format – is the data in the correct AAMVA standard? Even small errors in the barcode encoding can flag it. Some scanners won't even read a barcode that's printed too dark or with wrong dimensions. Also, test the magnetic stripe if your state uses it – though that's harder to fake well.
So yeah, that's my expanded list. Anyone else got something they always check that I'm missing?
