Between "I have a design" and "I have labeled jars" there are a handful of steps. Each one has an owner and something to approve. Knowing them ahead of time keeps a launch from stalling on a small detail.

The path, step by step

Step	Who does it	What you check or approve	Common slip
1. Label specs	Manufacturer or printer	You receive the label size, the template and the file rules	Designing before you have the template
2. Design draft	You or your designer	The look: name, colors, artwork	Text that is too small once it is on a curved jar
3. Product facts added	Manufacturer supplies the text	That nothing was retyped, cropped or covered	Editing the facts so they "fit better"
4. Proof	Printer or manufacturer	Every word, every number, the layout, the barcode	Skimming because it "looks right"
5. Approval	You	Your written sign off on one exact version	Approving in a chat message with no file attached
6. Printing	Printer	Nothing, unless you asked for a printed sample	Asking for changes after this point
7. Application	Manufacturer or you	Placement and straightness	No spare labels for mistakes
8. Final check	You	A few finished jars, compared with the approved proof	Leaving the cartons sealed until launch day

What a proof is, and is not

A proof is a picture of what will be printed. It is the last chance to catch a mistake. It is usually a digital file, so the color on your screen is only a guide. If an exact color matters to you, ask whether a printed sample is possible before the full run.

Check a proof slowly:

• Read it out loud, one line at a time.
• Compare the facts with the text your manufacturer sent.
• Check the label size and the product name against your order.
• Make sure the version number is the one you mean to approve.
• Print it at actual size, cut it out and wrap it around a jar or a can of similar size.

What approval means

When you approve a proof, you are saying "print exactly this". After that, a change usually means a new proof, and it can mean a reprint at your cost. Approve in writing, name the file and keep a copy.

No agency signs off for you. FDA's questions and answers on dietary supplements says FDA does not approve dietary supplements or their labeling. Its fact sheet for small cosmetics businesses says cosmetic labeling is not subject to premarket approval, and that responsibility sits with the manufacturer, packer or distributor whose name is on the label.

What changes on a round jar

You can see less than half of a round jar at one time, and the sides of that view bend away from you. Keep your brand name and product name in the middle of the front. Ask where the label seam will sit, and keep important text away from it. Leave the facts and the fine print for the sides and back, where people turn the jar to read.

Who applies the labels?

The manufacturer applies them. Labels go on as part of production, and you receive finished jars. This is the simpler choice for most first orders.

You apply them. You receive the jars and add your printed labels by hand. If you go this way:

• Order spare labels. Some will go on crooked.
• Work with clean, dry jars at room temperature.
• Make a simple guide from cardboard so every label sits at the same height.
• Press from the center outward to push air to the edges.
• Compare every tenth jar with the first one.

Keep the approved file

Save the final file, the proof you approved and the date. Your next order will go faster, and you will know exactly what was printed if a question comes up.

How OSM handles labels

For white label orders, you can try label ideas in OSM's online label studio. Those drafts are for planning. The studio does not create a compliant label or fill in the required product information. Ask OSM for the correct file and product facts, then prepare and submit your complete label. OSM provides courtesy feedback, not legal advice or compliance certification. You must independently check your label and claims. Wait for written go-ahead before ordering or sending labels. OSM printing is subject to a confirmed quote. Custom manufacturing projects settle label details as part of the quote. To start, contact OSM.

Common questions

How many proofs should I expect?

One or two, if your file was checked first. Each round adds time, so put all your changes into one message.

Can I change the design after printing?

Only by printing again. That is why the proof step matters.

Why does the printed color look different from my screen?

Screens make color with light. Labels make it with ink on a material. Some shift is normal.
