Most guidance on the mug sample process treats it as a delivery question: how fast a parcel can arrive and what the courier charges. That framing hides the risk. A sample is not a parcel to inspect and forget; it is the physical specification production copies, batch after batch, and the last cheap moment to change the body, the print or the pack.
This guide is for buyers running a physical sample for the first time. It covers what happens between a logo file and an approved master sample, what to check at each stage, and how the timeline and fee are handled, so you can brief a mockup worth reviewing, approve against written criteria, and plan production without losing your launch date.
Key takeaways
- A sample is a specification: sign the approved unit off against a written checklist, because every later batch is measured against it.
- The sequence runs mockup, artwork approval, sample, master sample: a complete brief gets a digital mockup within one hour.
- A physical sample takes 7–10 days after artwork approval, and the fee is credited against the production order.
- Colour is measured, not debated: ΔE against the approved sample, where about 1–2 is typically invisible.
- Production starts after master sample approval; allow 30–45 days for production and about 30 days for sea freight.
1. The sample is a specification, not a courier delivery
At a glance: the sample defines what correct means for the whole order; without an approved reference, QC can only judge a batch against opinion.
In a factory, the approved sample is a working object. It stays with QC and is compared with production units for body shape, glaze colour, print position, handle strength and packed presentation. An approval that says the sample looks good leaves the team guessing which details were agreed.
Sample orders can sit below the production minimum, so the first unit is a separate decision. Our MOQ guide explains how mixed designs and sample orders are handled.
| Stage | You receive | You approve | It locks |
|---|---|---|---|
| Digital mockup | Artwork on the chosen body, within one hour | Placement, scale, colour direction | Print area and layout |
| Artwork approval | Final print file, dieline, Pantone references | The file production prints | Colour, copy, print area |
| Physical sample | Decorated unit, 7–10 days after approval | Body, glaze, decoration, capacity | The object QC copies |
| Master sample | Signed unit, photographed, filed | The reference standard | Batch acceptance criteria |
| Production | Batch on the approved spec, 30–45 days | Nothing new | Ship date and QC plan |
2. Stage one: the mockup fixes placement
At a glance: a mockup is a placement test, not a colour proof; use it to fix layout and scale, then expect the fired glaze to move the colour slightly.
A mockup answers what a flat logo file cannot: does the artwork clear the curve at the base, does the handle cut through the design, is the mark legible at 4 cm, does a wrap close without a seam? We issue one free within an hour of a complete brief, so the brief matters more than the software.
Two limits matter. A screen cannot show how a decal sits under glaze, how a matte finish flattens a dark colour, or how a gold rim reads in raking light. And a mockup on the wrong body misleads you about print area. Settle the body first: our customisation pages set out the decoration routes.
3. Stage two: artwork approval fixes the file
At a glance: artwork approval is a document sign-off; it fixes the print file, the colour references and the dieline before a single mug is decorated.
Production prints what was approved, not what was intended. The pack should hold the final vector file, a Pantone reference per spot colour, the print area drawn on the dieline, the copy checked for spelling, and care wording that fits the decoration.
This is also where decoration becomes a manufacturing constraint. A photograph needs sublimation and a coated body; six spot colours push you towards decal; a gold rim rules out microwave use. For logo-led programmes, our logo mugs page lists standard bodies and print areas.
4. Stage three: the physical sample
At a glance: a physical sample takes 7–10 days after artwork approval, and it is the only stage that proves capacity, hand feel, registration and packed survival.
The physical sample is the slowest stage of the mug sample process: the unit is formed, glazed, printed and fired on the same route as production, then checked. Our sample room records the firing batch with the sample, so a glaze approved this quarter can still be compared with a batch made six months later.
Start with the body: straight wall, level rim, a handle that clears the knuckles, usable capacity in millilitres to the intended fill line rather than the nominal ounce figure. Then the decoration: position against the dieline, colour against the approved reference with a ΔE reading where colour is critical, no pinholes under the glaze. Then the conditions your customer will create: drop test in the packed carton, dishwasher cycle if the claim allows, microwave test where relevant.
| Stage | Check | Verify | If it fails |
|---|---|---|---|
| Mockup | Print area, scale, wrap | Against the dieline at 100% | Re-render |
| Artwork | Colour references, copy, care wording | Read at actual size | Re-approve |
| Physical sample | Capacity, handle, glaze, registration | Fill test, ΔE vs reference | Re-sample |
| Packed sample | Drop test, carton fit, inner tray | Drop the packed carton | Change the pack |
5. Stage four: master sample approval
At a glance: the master sample is the signed reference the factory keeps; approving it starts the production clock and closes the specification.
Approval is formal. The approved unit is photographed, labelled with the artwork version and sample number, and filed with the batch record. In-process checks at forming, glazing, printing and firing are compared with it, with ΔE readings, print positions and kiln records logged per batch. Final inspection checks handle strength, drop test results and packing against the same reference, and a photo QC report follows.
Approve in writing with the sample number and artwork version, not in a message that scrolls away. If the sample is almost right, decide whether the deviation is acceptable before you sign, because a signed sample with a known flaw becomes the standard for the order. The cost logic sits in our cost and sourcing articles.
| Step | Timing | Cost handling | You receive |
|---|---|---|---|
| Digital mockup | Within 1 hour of a brief | Free | Visual on the chosen body |
| Physical sample | 7–10 days after artwork approval | Fee credited against the order | Decorated, packed unit |
| Sample courier | Depends on service and destination | Quoted before dispatch | Tracking and packing list |
| Artwork revisions | Inside the Launch Kit window | 2 rounds from 500 pcs | Revised visuals and dielines |
| Production | 30–45 days after approval | Part of the order | Batch with photo QC report |
The courier line is the one buyers forget. A sample is a small parcel, but transit time and charge depend on service and destination. Our guide to shipping mugs from China explains why a sample and a pallet are quoted differently.
6. How MugFactory de-risks the sample stage
MugFactory produces ceramic, bone china and stoneware mugs on our exclusive Liling lines, with design, packaging, QA and export documents held by one in-house team. The factory has run since 1994 and now operates six production bases, ten branch factories and twenty kilns, so your sample and the batch behind it come off the same equipment.
- Pre-production review of body, capacity, decoration and packaging, with material verification before sampling.
- A free digital mockup within one hour of a complete brief.
- Physical samples in 7–10 days after artwork approval, fee credited against the order.
- In-process checks at forming, glazing, printing and firing, with ΔE and kiln records per batch.
- Final inspection with drop test, food-contact reports on request and a photo QC report.
When the sample has to become a launch, the Launch Kit adds product photography, a spec sheet and print-ready dielines. The help and FAQ answers courier, packing and payment questions.
7. Sample mistakes that create production rework
At a glance: most rework in the mug sample process traces back to a sample approved without a written reference, or to a change requested after capacity was booked.
- Approving from a photograph. A photo hides weight, scale and how light sits on glaze; hold the unit first.
- Changing artwork after approval. Every change resets the print file, the sample and often the production slot.
- Testing the mug but not the pack. A unit that survives a kitchen floor can still fail in an undersized carton.
- Leaving care wording until the end. Gold rims are hand wash only and not microwave safe, and the label must say so.
- Signing a deviation you cannot repeat. If the approved unit is not reproducible on the line, the reference is worthless.
Test the body and the finish first
Send us the artwork, the body you have in mind and the date you need stock. We will place it on a mockup within one hour and quote a physical sample against the same specification.
FAQ
How long does a sample take?
The mug sample process has two clocks: 7–10 days for a physical sample after artwork approval, then courier transit. The digital mockup before it is issued within one hour of a complete brief. If the artwork changes, the sample clock restarts at each new file, so the real variable is usually your own approval speed.
Is the sample fee refunded against production?
The sample fee is credited against the production order, so the cost is recovered when you proceed. Courier charges are quoted separately and depend on destination, service and weight. Ask for both lines to be shown on the quote so competing offers can be compared on the same basis.
Can we get a mockup before paying for a sample?
Yes. A free digital mockup is produced within one hour of a complete brief, before any sample fee is raised. It shows placement, scale and colour direction on the body you have chosen. Treat it as a layout check rather than a colour proof, because fired glaze and metallic rims behave differently in the hand.
How many revision rounds are included?
The Launch Kit, included with programmes from 500 pieces, covers two rounds of artwork revision and is delivered within 3–5 working days of artwork approval. Ask for any extra rounds to be priced before work starts, and number each version so the approved file is never confused with a draft.
What is a master sample?
The master sample is the approved physical unit kept as the reference standard for production. It is photographed, labelled with the sample number and artwork version, and filed with the batch record. In-process checks and final inspection compare batches against it, which is why a written approval beats a photograph in an email.
