The 7-Step Quality Control Checklist for Custom Scratch-Off Tickets

What This Checklist Is For

If you're ordering custom scratch-off tickets for a promotion, event, loyalty program, or fundraising campaign, you need to know what you're looking at when that first proof arrives—or worse, when the pallet shows up at your door.

I'm a quality compliance manager for a packaging and print company. Over the past four years, I've reviewed roughly 300+ unique print projects annually, including a significant number of scratch-off and instant ticket runs. I've rejected about 12% of first deliveries in 2024 alone due to issues that could've been caught earlier.

This checklist covers the verification steps I use when working with a secure instant ticket manufacturer or any lottery ticket printing company. Use it when you're reviewing proofs or inspecting finished goods. It'll save you from the kind of reprint cost I've seen too many times.

Step 1: Verify the Security Substrate and Variable Data

This isn't just about printing. A custom lottery tickets for promotions run requires a security substrate—the base material with built-in tamper evidence or hidden features. Don't skip this.

What to check:

• Confirm the scratch-off latex matches your approved color swatch. (We had a batch where the silver latex was slightly gray. The client rejected it because it looked 'cheap' on camera.)
• Ask for a random sample of 10–20 tickets from the run. Scratch them open. Verify the variable data (prize codes, serial numbers) is readable and correctly applied.
• Check for see-through issues. Hold a ticket up to a bright light. Can you see the prize text underneath? If yes, that's a fail.

I should add that I once approved a sample that looked fine under office lighting. When the client inspected it under their retail store's fluorescent lights, the see-through was obvious. Now I always test under multiple lighting conditions.

Step 2: Inspect the Paper Stock and Finish

The substrate matters for feel, durability, and how the scratch-off adheres. For bespoke scratch off stickers or cards, you want a stock that doesn't curl after the latex dries.

Check these:

• Grammage (paper weight) within ±5% of spec. Light paper feels flimsy. Heavy paper costs more. Find the balance for your use case.
• Coating consistency. If the stock is too porous, the latex can soak in and become impossible to scratch off cleanly. If it's too glossy, the latex may delaminate.
• Cut quality. Rounded corners should be consistent. Burrs or rough edges indicate dull dies.

Looking back, I should have insisted on a caliper test for a 50,000-unit order of personalized lottery tickets for a client's anniversary campaign. The paper felt fine in the proof, but a full pallet had variations of 0.1 mm. It didn't affect functionality, but it looked unprofessional when stacked.

Step 3: Check Registration and Print Alignment

Misregistration on a scratch-off ticket is a disaster. If the printed prize area isn't aligned with the scratch-off patch, customers can damage the ticket or expose the prize prematurely.

What I look for:

• Front-to-back registration. The scratch-off patch on the front must perfectly cover the prize printing on the back. Even a 1 mm shift can cause issues.
• Color registration. For full-color scratch off card manufacturer jobs, check that CMYK plates align. Out-of-register colors look amateurish and hurt brand perception.
• Ask the secure instant ticket manufacturer for their registration tolerance. Industry standard is usually ±0.5 mm for multi-color. Anything more is risky.

I once rejected a batch because the registration was off by 1.2 mm on the entire run. The vendor claimed it was 'within industry standard.' It wasn't. We sent it back and they reprinted at their cost. That experience cost us a two-week delay, but it also taught me to spec registration tolerances in every contract from then on.

Step 4: Validate Scratch-Off Performance

This is the most overlooked step. You're ordering bespoke scratch off stickers for a reason—people need to scratch them. If the latex is too hard, customers give up. If it's too soft, it flakes off in transit.

Perform a scratch test:

• Cure time. Freshly printed latex needs 24–48 hours to cure. If you're doing a rush inspection, account for this.
• Coin test. Simulate a customer scratching with a coin. The latex should come off cleanly in one or two passes without tearing the paper.
• Fingernail test. Try scratching with a fingernail. It should be possible, but not effortless. If it comes off too easily, the scratch-off is vulnerable to accidental rubbing during shipping.

In Q1 2024, we received a shipment of custom lottery tickets for promotions where the latex hadn't cured properly. The client reported that 30% of the tickets had the scratch-off patch flaking off before customers even used them. The fix cost the printer $18,000 in reprints. If I'd waited another day for the cure test, I'd have caught it.

Step 5: Examine the Print for Abrasion and Scuffing

Scratch-off tickets are handled a lot—packed, shipped, displayed, scratched. The print must withstand abrasion. If the ink scuffs off before the customer scratches, the ticket looks used and damage brand perception.

What to do:

• Rub test. Take a clean ticket and rub the printed surface firmly with your thumb. If ink transfers, you have a scuffing problem.
• Stack test. Place a stack of 50 tickets face-to-face. Press down and slide the top ticket. Check for ink transfer onto the back of the ticket above.
• Scuffing is especially common on personalized lottery tickets with metallic inks or dark backgrounds. The overprint varnish must be applied.

Step 6: Confirm Serialization and Tracking

For any lottery ticket printing company, serialization is critical. Even for non-gambling promotions, you need to match winners to claimed prizes and audit the run.

Verification steps:

• Check that serial numbers are sequential and no tickets are missing from the sequence. If you ordered 10,000 tickets and the serial numbers skip from 5,000 to 5,002, you have a problem.
• Verify that any bar codes or QR codes scan correctly. I use a handheld scanner and do a random sample of 50 tickets.
• If there are prize tiers, confirm the proportion of winning tickets matches your spec. You don't want a promotion where 50% of tickets are winners when you only budgeted for 10%.

I've seen a case where a vendor printed 10,000 tickets but the last 2,000 had identical serial numbers. The client only discovered this when the first 200 'unique' winners turned in identical codes. Total loss: about $15,000 in unverified claims.

Step 7: Perform the Final Pack-Out Inspection

The quality of the print doesn't matter if the packaging ruins it. A secure instant ticket manufacturer should handle packing with care.

Check:

• Packaging condition. Boxes should be clean, dry, and not crushed. Damaged boxes can mean damaged tickets inside.
• Shrink wrap integrity. For bulk orders, each bundle should be tightly wrapped to prevent movement during transit.
• Quantity verification. Count a few boxes to confirm you received what you ordered. Mistaken counts happen more than you'd think.

Common Pitfalls and What They Cost

I'll be honest: most issues we see aren't from malicious vendors. They're from rushed production or unclear specs. But the cost is real.

Take the case of a bespoke scratch off stickers order for a retail launch. The buyer saved $200 by choosing a cheaper substrate. The stock was too thin, and the latex bled through. The entire run of 8,000 stickers was ruined in storage. The total loss? Over $3,000 including the reprint and expedited shipping.

Or consider a custom lottery tickets for promotions job where the client didn't do a scratch test until after delivery. By then, the promotion had started and the tickets had to be pulled from stores. The embarrassment alone hurt their brand more than the $5,000 reprint cost.

When you're working with a scratch off card manufacturer, remember that the cheapest option often isn't the cheapest in the long run. The $50 per thousand you save on the base price can cost you ten times that in reprints and lost customer trust.

Final Thought

Use this checklist as your starting point. Customize it for your specific product and promotion. And if you're unsure about a spec, ask the manufacturer for clarification—or get a second opinion. I've saved clients from expensive mistakes just by asking one extra question during proof review.
