How to Prepare Artwork Files for Custom Packaging Printing

You may have already confirmed the product, packaging structure and quotation. それから, just when the project seems ready to move forward, the supplier asks one more question:

“Can you send us the print-ready artwork?”

This is where many custom packaging projects suddenly slow down.

Correct custom packaging artwork files help prevent missing fonts, blurry logos, incorrect colors, misplaced hot stamping, outdated dielines and unnecessary sample revisions. さらに重要なことは, good artwork allows the packaging supplier to understand exactly how your box or tube should be printed and finished.

それで, before you send that final AI or PDF file, it is worth checking whether the artwork is actually ready for production—not simply whether it looks good on your screen.

この包装タイプは何ですか?

In this article, we are not talking about one particular box or paper tube. その代わり, we are talking about the technical artwork required to manufacture custom paper packaging.

Custom packaging artwork files are production files built on the approved packaging dieline.

Unlike a JPG mockup, they tell the factory where to:

• Print
• Cut
• Fold
• Glue
• Apply foil
• Emboss
• Deboss
• Apply spot UV
• Create a window
• Position regulatory text

言い換えると, the mockup explains the visual idea, while the technical artwork explains how that idea becomes a physical package.

Common Artwork Components

A packaging production file may contain:

• ディエリン
• Cut line
• Crease line
• Glue area
• ブリード
• Safe area
• CMYKアートワーク
• パントンカラー
• Product text
• バーコード
• Hot-stamping layer
• Embossing layer
• Debossing layer
• Spot UV layer
• Window line
• Insert artwork

したがって, the final artwork should always be created around the approved production structure rather than an estimated size.

Preferred Artwork Formats

For many packaging projects, editable formats such as these are practical:

• AI
• Editable PDF
• EPS

その間, high-resolution PSD or TIFF files may be used for photographs or raster artwork.

Vector graphics are especially useful for logos, 文章, dielines and finishing areas because Illustrator vector artwork can be scaled for print without the pixelation associated with low-resolution raster graphics.

Why JPG or PNG Is Usually Not Enough

A JPG may show the design clearly. しかし, it normally does not contain editable:

• Dielines
• Spot colors
• Foil paths
• Embossing paths
• Cutting paths
• Separate finishing layers

したがって, a JPG is better treated as a visual reference rather than the only production file.

If you only have a JPG, tell the packaging supplier early. The design or prepress team can then determine whether the artwork needs to be rebuilt.

一般的なアプリケーション

The preparation of custom packaging artwork files varies according to the product category.

Perfume Packaging

Perfume packaging often looks visually simple but may involve several premium finishing processes.

例えば, a rigid perfume box or paper tube may require separate layers for:

• Dark green Pantone printing
• 金箔ロゴ
• Embossed brand mark
• マットラミネート
• Insert branding

If the gold logo must also be embossed, the supplier needs to know whether the embossing follows exactly the same shape.

したがって, separate the layers clearly.

A practical Illustrator layer structure could look like:

• DIELINE
• CMYK PRINT
• PANTONE
• GOLD FOIL
• EMBOSS
• SPOT UV
• INSERT

This makes communication much easier.

Skincare and Cosmetics

Cosmetic packaging often contains more written information than perfume packaging.

Typical content may include:

• Product name
• Ingredients
• Directions
• Net contents
• Warnings
• Manufacturer details
• バーコード
• Batch information

その結果, typography and safe areas become especially important.

Before sending the artwork, check whether small text is too close to:

• Fold lines
• Cutting edges
• Windows
• Glue flaps
• Tube seams

Tea and Coffee

Tea and coffee packaging frequently combines branding with detailed product information.

This may include:

• Country of origin
• Flavor notes
• 醸造手順
• Ingredients
• Net weight
• バーコード

If the artwork is printed on natural kraft paper, keep in mind that the brown paper base will affect how colors appear.

したがって, do not assume that a color shown on a white monitor will reproduce identically on kraft paper.

Chocolate and Candy

Chocolate and confectionery packaging often combines:

• CMYK illustrations
• Photography
• 金箔
• Windows
• Product information

A window introduces an additional technical area.

したがって, the artwork should clearly show the window die-cut line while keeping text and important graphics outside the required production tolerance.

Candle Packaging

Candle packaging often uses simpler, more premium artwork.

A typical design might combine:

• Dark background
• Brand logo
• Scent name
• Botanical illustration
• 金箔
• 製品重量

しかし, dark surfaces can make small printing or finishing inconsistencies more visible.

したがって, physical sampling is especially valuable for premium candle packaging.

ギフト包装

Gift packaging gives designers more creative freedom.

しかし, structures such as drawer boxes, magnetic boxes and telescopic packaging have several visible surfaces.

その結果, the designer should consider the entire unboxing sequence rather than designing only the front panel.

材質のオプション

The paper selected for production affects how custom packaging artwork files will reproduce in real life.

クラフト紙

Natural kraft paper has a brown base tone.

したがって, bright colors may appear more muted compared with printing on white coated paper.

Suitable design directions include:

• 黒印刷
• Dark green
• Brown
• White ink where supported
• 銅箔
• Matte gold foil

実際には, the natural material itself can become part of the artwork.

アート紙

Coated art paper provides a smooth surface for:

• CMYK印刷
• パントン
• Photography
• Fine typography
• グラデーション
• 詳細なイラスト

Afterward, it can receive:

• マットラミネート
• グロスラミネート
• ソフトタッチラミネート加工
• Anti-scratch lamination

特殊紙

Specialty papers may include:

• Linen texture
• Leather texture
• 金属紙
• Pearlized paper
• Dyed-through paper
• Embossed texture

しかし, deeply textured surfaces can reduce the visual clarity of very fine details.

したがって, extremely thin logo lines or small foil details may need to be simplified before production.

Food-Grade Paper

Food packaging may require approved food-contact materials or internal barrier components.

しかし, these technical materials are generally specified separately from the outer decorative artwork.

例えば, the external design may be printed on art paper, while the inside uses:

• Food-grade paper
• PEコート紙
• Grease-resistant paper
• ホイルライナー
• Inner pouch

Foil Liner

お茶, コーヒー, nuts and snack tubes may use an aluminum foil or multilayer liner.

いつもの, the exterior artwork file still controls only the outer branding.

しかし, if an internal component also requires printing, provide separate artwork and clearly identify the part.

構造オプション

Packaging structure should be finalized before the designer completes custom packaging artwork files.

さもないと, a structural change may force the artwork to be redesigned.

Paper Lid Tube

A standard paper tube normally contains:

• Main body
• 蓋
• Bottom
• Seam area

Avoid placing the main logo directly over the vertical seam.

その代わり, define the primary viewing area.

ショルダーネックチューブ

A shoulder-neck tube contains an inner neck that becomes visible after the lid is removed.

This creates another branding opportunity.

例えば:

• Dark green exterior
• Gold inner neck
• Cream interior

しかし, all visible components should be included in the approved material and production specification.

Telescopic Structure

A telescopic tube may use:

• Long upper lid
• Short lower base
• Inner insert

したがって, the designer should confirm:

• Upper-section height
• Lower-section height
• Overlap
• Front orientation

Do not guess these dimensions.

Window Packaging

Window artwork must use the approved die-cut position.

The design should consider:

• Window shape
• Window size
• Film area
• Product position
• Safe area

さらに, the real product should remain aligned behind the window.

Paper Tube With Insert

An insert may use:

• エヴァ
• EPE
• Paperboard
• Molded pulp
• Plastic tray

If the insert includes printed paper or a branded card, provide a separate artwork file.

Push-Up Tube

Push-up paper tubes contain moving internal components.

したがって, critical graphics should stay away from areas where movement or seams may affect visibility.

Twist-Up Tube

Twist-up packaging requires precise dimensions.

このため, the final dieline should be approved before artwork production begins.

Sleeve Packaging

Sleeves can be very useful for multiple SKUs.

例えば, one base package may be used for five different products while each product receives a different sleeve.

結果として, brands can reduce structural complexity while maintaining product differentiation.

印刷 & 仕上げオプション

This is where custom packaging artwork files become especially important.

Different printing and finishing processes should not be merged into one unidentified artwork layer.

CMYK印刷

CMYK is commonly used for process printing involving:

• Photography
• グラデーション
• イラスト
• Multicolor graphics

Adobe’s Illustrator print documentation instructs users to switch RGB documents to CMYK mode when preparing color separations for process printing.

しかし, printed color can still be influenced by the paper, ink, coating and finishing.

したがって, do not approve critical brand colors solely from a phone or monitor.

パントン / Spot Colors

Spot colors are useful when a brand requires a particular signature shade.

例えば:

• Brand green
• Burgundy
• Navy
• Orange

Clearly identify the required Pantone or spot color in the artwork.

Do not simply write:

“Please match this green.”

加えて, request a physical proof when strict color matching is commercially important.

Hot Stamping

Hot stamping should normally be provided as a separate vector layer.

例えば:

GOLD FOIL

Do not create a gold gradient in Photoshop and assume that it communicates metallic foil production.

その代わり, provide a clean vector shape showing exactly where the foil should be applied.

エンボス加工

Embossing raises the surface.

したがって, provide a separate vector layer showing the exact embossed area.

A simple label could be:

EMBOSS

If foil and embossing must register together, make that clear in both the artwork and production instructions.

デボス加工

Debossing creates a recessed surface.

Like embossing, it should be supplied as a separate, clearly labeled vector area.

スポットUV

Spot UV creates glossy contrast over selected areas.

したがって, create a separate layer called:

SPOT UV

Do not merge the effect into the CMYK artwork.

マットラミネート加工

Full matte lamination normally applies across the entire printed surface.

したがって, it usually does not need its own artwork layer.

その代わり, specify the film in the finishing requirements.

グロスラミネート

Gloss lamination follows the same principle.

しかし, if only one logo or pattern needs gloss, the process may actually be spot UV rather than full gloss lamination.

How to Prepare Custom Packaging Artwork Files

Before sending custom packaging artwork files to the factory, go through the following workflow.

ステップ 1: Use the Final Approved Dieline

Never design final production artwork on an early structural drawing.

If the package dimensions change, request a new dieline.

ステップ 2: Keep the Dieline at Actual Size

Do not resize or stretch the dieline.

A production dieline should represent the actual package dimensions.

ステップ 3: Add Bleed

If background colors, photographs or illustrations reach the trim edge, extend them beyond the final trim line.

Illustrator supports document bleed and printer marks through its Marks & Bleed controls.

Many commercial projects use approximately 3 mm, but the packaging supplier’s specification should always take priority.

ステップ 4: Respect the Safe Area

Keep important elements away from trim and fold tolerances.

These elements include:

• ロゴ
• バーコード
• Product name
• Ingredients
• Small text

ステップ 5: Prepare the Correct Print Color Mode

For process printing, prepare the file using the agreed CMYK workflow.

If Pantone colors are required, identify them separately.

ステップ 6: Check Fonts

Missing fonts can change text layout.

したがって, either outline the fonts where appropriate or package the required font resources according to the agreed workflow.

Adobe Illustrator’s Package command can collect the Illustrator file together with linked graphics and eligible font resources for handoff.

Always keep an editable master version before converting text into outlines.

ステップ 7: Check Linked Images

One of the most common handoff problems is missing linked images.

Illustrator’s Links panel shows placed linked and embedded files, while the Package function can gather linked assets for transfer.

Before sending the project, check that every required image is included.

ステップ 8: Keep Logos Vector Where Possible

Vector logos produce cleaner results for:

• 印刷
• ホットスタンピング
• エンボス加工
• Scaling

Avoid extracting a small logo from a website screenshot.

ステップ 9: Separate Special Finishing Layers

A good file structure could be:

• DIELINE
• CMYK
• PANTONE
• GOLD FOIL
• EMBOSS
• DEBOSS
• SPOT UV
• WINDOW

This makes the intended manufacturing processes obvious.

ステップ 10: Check Overprint

Overprint settings can change how overlapping objects reproduce.

Illustrator includes dedicated overprint and color-separation controls, so these settings should be reviewed during prepress when relevant.

ステップ 11: Export a Print-Ready PDF

Along with the editable file, export a high-quality PDF reference.

Illustrator supports PDF creation for print workflows, including PDF/X-related options.

The supplier can use the PDF to compare the intended layout against the editable artwork.

ステップ 12: Include a 3D Mockup

A 3D rendering is not the technical production file.

それにもかかわらず, it is very useful because it shows:

• Front orientation
• Opening direction
• ロゴの位置
• Expected finished appearance

言い換えると:

Artwork tells the factory how to produce it.

Mockups tell the factory how you expect it to look.

Providing both reduces ambiguity.

Packaging Artwork Preflight Checklist

Before sending your file, チェック:

• Correct dieline
• Correct packaging size
• Bleed included
• Safe zone checked
• CMYK workflow confirmed
• Pantone colors identified
• Fonts supplied correctly
• Linked images included
• Logos are vector
• Image quality checked
• Barcode checked
• Text proofread
• Foil layer separated
• Embossing layer separated
• Debossing layer separated
• Spot UV layer separated
• Window position confirmed
• Dieline kept separate
• PDF exported
• Mockup supplied
• Final internal approval completed

Acrobat Pro’s Preflight tools are specifically designed to analyze PDFs for print-production problems before output.

How Artwork Affects Sampling and Production Time

Poorly prepared custom packaging artwork files can delay a packaging project before manufacturing even starts.

例えば:

The supplier receives a JPG.

Then the editable artwork is requested.

次, the AI file arrives but linked images are missing.

その後, the correct images are supplied.

しかし, the dieline is outdated.

Once the dieline is corrected, the designer discovers that the foil layer has not been separated.

Another revision is required.

At this point, several days may have passed—even though no mass-production machine has started.

したがって, good artwork preparation can directly improve the efficiency of the packaging development process.

Planning Your Packaging Lead Time?

Artwork approval is only one part of the overall project.

If you are also planning sampling, production and delivery, read our Custom Paper Tube Production Time: Complete Lead Time Guide.

That guide explains how:

• アートワークの承認
• サンプリング
• MOQ
• 材料の入手可能性
• Inserts
• Special finishing
• Multiple SKUs

can influence the complete production schedule.

Together, these articles answer two important purchasing questions:

Is my artwork ready for printing?

そして

How long will production take after it is approved?

Common Artwork Mistakes

Sending Only a Screenshot

A screenshot may show the design direction, but it usually cannot provide the editable technical information required for production.

したがって, supply editable artwork whenever possible.

Designing Before the Structure Is Final

If the dieline changes, artwork positions also change.

その結果, finalize the packaging structure first.

Missing Linked Files

Check all linked photographs and graphics before sending the project.

Low-Resolution Logos

A logo copied from a website may look acceptable on a monitor but reproduce poorly in print.

その代わり, ask for the original vector version.

Using Too Many Unidentified Layers

Clear layer names reduce communication problems.

例えば:

Layer 17 Copy 2

is much less useful than:

GOLD FOIL.

Merging Foil Into CMYK

The printer needs to know what should be printed and what should be foil stamped.

したがって, keep those processes separate.

Ignoring the Tube Seam

For cylindrical packaging, avoid placing important branding on the spiral or vertical outer-wrap seam whenever the structure makes that area visually sensitive.

Designing on Hidden Areas

Some artwork can disappear beneath:

• Lid overlap
• Glue flaps
• Inner folds
• Sleeves

したがって, check the assembled package before approving the design.

コンプライアンス & 持続可能性

Packaging artwork can also contain regulatory or compliance information.

Depending on the product and market, this may include:

• Product name
• Ingredients
• Net contents
• Warnings
• Manufacturer information
• Batch area
• バーコード
• Recycling information

The brand, importer or responsible party should confirm the exact regulatory requirements for the destination market.

FSC

If an FSC trademark is used, its use should comply with the applicable certification and trademark-approval requirements.

したがって, do not simply download an FSC logo and place it on packaging without confirming authorization.

Food Contact

Food-contact safety depends on the approved packaging materials and full construction, not simply the exterior graphics.

Depending on the application, buyers may request:

• Food-contact reports
• Migration reports
• Material declarations
• Ink information
• Adhesive information

BRC and IFS

BRCGS Packaging Materials and relevant IFS systems may support supplier-quality or food-packaging requirements.

しかし, certification references and logos should only be used appropriately.

EUDR と EPR

For applicable markets and supply chains, packaging buyers may also need to consider material due diligence and producer-responsibility requirements.

したがって, regulatory review should happen before the final artwork is locked whenever these requirements affect printed information.

Sustainable Artwork Choices

Luxury packaging does not automatically require the maximum number of finishing processes.

例えば, good typography combined with textured paper and one small foil logo may create a stronger premium effect than:

• Full lamination
• Large foil areas
• Several metallic colors
• Multiple UV coatings

したがって, good design can sometimes reduce production complexity as well as material use.

よくある質問

1. What file format should I send for packaging printing?

編集可能なAI, PDF or EPS files are commonly useful for packaging production. A PDF reference and 3D mockup can also make the intended finished appearance clearer.

2. Should packaging artwork be CMYK or RGB?

For standard process printing, artwork is typically prepared in a CMYK print workflow. Illustrator provides CMYK document mode and separation controls specifically for print output.

3. Do I need bleed?

If artwork reaches the trim edge, bleed is generally required. Illustrator supports defined bleed areas and bleed marks, while the exact amount should follow the packaging manufacturer’s specification.

4. Do fonts need to be outlined?

Fonts can be outlined where appropriate or supplied through an agreed packaged workflow. Always keep an editable master file because outlined text is no longer normal editable type.

5. Do foil, embossing and spot UV need separate layers?

はい. Clearly separated vector layers make it much easier for the prepress and production teams to identify each special process.

6. Can I send a Canva, JPG or PNG file?

You can use them as references. しかし, the packaging supplier may still require editable production artwork containing dielines, vector logos and special-finishing information.

7. Why does the printed color look different from my monitor?

Screen display and physical printing use different output processes, while paper, ink, coatings and lighting can also influence the final appearance.

したがって, physical approval is recommended when exact brand color matters.

8. Can you help check my artwork before printing?

はい. The design and prepress team can review the artwork against the approved structure and identify potential production issues before sampling.
