Print-ready files are production files, not simply files that have been exported as PDFs. For cards, boxes, and instruction booklets, the file must show the correct finished size, cutting or folding information, bleed, safe area, artwork order, and any separate finishing layers.
This guide focuses on the files EzraCard needs to manufacture custom playing cards, game cards, trading cards, tarot cards, card boxes, and instruction booklets. The examples show how to apply the measurements in a real file instead of only defining printing terms.
Use the current project template whenever one is supplied. The template and written production specification take priority over the examples below because material, equipment, finishing, and binding can change the required setup.
What a Print-Ready File Must Show
A usable production file should allow the prepress team to answer these questions without guessing:
- What is the final trimmed or folded size?
- Where is the cut, fold, crease, perforation, or window?
- How far should background artwork extend past the cut?
- How far should text, logos, numbers, and borders stay from the cut?
- Which page, card face, card back, box panel, or booklet page belongs in each position?
- Which elements print in CMYK, spot color, white ink, foil, UV, or another finish?
- Which PDF standard, color profile, font treatment, and printer marks are required?
A PDF can still fail these checks. Common problems include a wrong artboard size, missing bleed, low effective resolution, substituted fonts, incorrect front-and-back order, an overprinting white object, a dieline that prints by mistake, or a missing special-finish mask.
A typical file approval path is:
- Project specification: Confirm product, dimensions, material, quantity, packaging, and finishes.
- Production template: Download or request the current card, box, or booklet template.
- Artwork: Add the design to the template without changing its scale.
- Prepress check: Review dimensions, bleed, safe area, color, fonts, layers, and page order.
- Proof: Review a digital or physical proof when the project requires one.
- Approval: Approve the final content and production specification before manufacturing.
EzraCard has prepared a quick video guide
Card Dieline Example: 63 × 88 mm Playing Card
A card file becomes much easier to check when the finished size, trim line, bleed boundary, and safe area are defined separately. The following is an example for a card with a finished size of 63 × 88 mm.
This is an example of how the measurements work, not a universal specification for every card. Use the dimensions in the approved EzraCard template when they differ.
Apply the Measurements
| Reference | Example dimension | What it means in the file |
|---|---|---|
| Finished size / trim size | 63 × 88 mm | The final card size after cutting. The actual trim line remains at 63 × 88 mm. |
| Safe area | 57 × 82 mm | If the template requests a 3 mm safe margin on every side, important content stays inside a rectangle inset 3 mm from the trim line. |
| Bleed boundary | 69 × 94 mm | If the template requests 3 mm bleed on every side, edge-to-edge backgrounds extend 3 mm beyond the trim line. |
| Trim line | 63 × 88 mm | The intended cut path. It is not the outer bleed boundary. |
Important distinction: the outer 69 × 94 mm boundary in this example is the bleed boundary, not the actual trim line. The card is still cut to 63 × 88 mm. Some supplier templates label guides differently, so follow the labels in the supplied file.
What Goes Inside Each Area?
- Inside the 57 × 82 mm safe area: Keep titles, logos, card values, numbers, symbols, important illustration details, and narrow borders.
- Between the safe area and trim line: Use background or secondary artwork only when a small cut shift will not damage the design.
- Through the 3 mm bleed: Extend backgrounds, textures, and photographs that should reach the card edge.
- On the 63 × 88 mm trim line: Place the approved vector cut path or follow the template’s trim guide.
Do not place a white background only up to the trim line. If the background is intended to reach the edge, extend it through the bleed. Do not place a logo or card number on the bleed boundary and hope the cut will preserve it.
Card Dieline and Rounded Corners
A rounded card corner is not created by drawing a general 3 mm inset or by guessing the radius. The corner radius belongs to the approved card dieline and can vary with the card format, cutting tool, and material.
Keep important artwork away from the curved corner area even when it sits inside the straight-edge safe margin. If the project uses a custom-shaped card, request an approved vector dieline before finalizing the front and back artwork.
Front, Back, and Card Sequence
Supply the card fronts, backs, and production list in a structure the manufacturer can verify. Confirm whether the back is viewed from the same orientation as the front or needs a specific rotation. Do not mirror or rotate card backs unless the production specification asks for it.
For custom playing cards, check card size, corner radius, shared backs, face sequence, borders, special cards, and any foil, UV, holographic, or white-ink layers before export.
Card Box Dieline: How to Prepare Packaging Artwork
A card box is not prepared as one flat rectangle. Its dieline contains panels and production operations that must stay aligned with the finished box.
Read the Box Dieline Before Designing
Identify the following lines and areas in the supplied template:
| Dieline element | What it controls | Artwork action |
|---|---|---|
| Cut line | The outside edge that will be cut | Keep critical text and logos away from the cut; extend edge artwork through the required bleed. |
| Crease or fold line | Where the board folds | Do not place small text, faces, or important details directly across the crease unless approved. |
| Glue flap | Where the box is joined | Follow the template’s printable and non-printable instructions; do not assume every glue flap receives full artwork. |
| Panel boundary | The front, back, side, top, or bottom panel | Keep panel-specific text and logos inside the correct panel orientation. |
| Bleed boundary | The extra artwork outside a cut edge | Extend background artwork only as far as the supplied template requires. |
| Barcode or legal area | Required scannable or regulatory information | Reserve a flat, readable area and confirm its final size before printing. |
Practical Box Example
Assume the approved box template requests 3 mm bleed and a 3 mm minimum safe margin from every cut and fold. The background color of the front panel should continue past the front-panel cut edge into the bleed. The product name should remain at least 3 mm inside the relevant cut and fold guides. A logo that crosses a fold should be moved or redesigned if the fold would interrupt its readability.
This 3 mm example applies only when the project template specifies it. Box materials, coating, construction, and cutting tolerance can require a different margin. Never redraw a box dieline using a generic rectangle.
Box Artwork Layers
Keep the CMYK or approved color artwork separate from cut, crease, fold, perforation, and glue information. Use the layer names and spot-color names supplied in the template. A dieline that is accidentally included in the printable artwork can appear as a visible line on the finished box.
Review custom card box options before completing the artwork because card quantity, material thickness, tuck or rigid construction, inserts, and packaging finishes affect the dieline.
Instruction Booklet and Manual Print Files
Instruction booklets introduce page-order, binding, margin, and cover problems that do not occur in a single card file.
Confirm the Booklet Specification
- Finished page size
- Page count
- Paper or booklet stock
- Binding method
- Bleed and safe margins
- Cover and inside-page setup
- Spine width, when applicable
- Reading order and language versions
Booklet Size Example
For an illustrative A5 booklet, the finished page size is 148 × 210 mm. If the approved specification requests 3 mm bleed on all sides and the file is built to the bleed boundary, the artwork page becomes 154 × 216 mm. The finished page is still trimmed to 148 × 210 mm.
The inner safe margin is not automatically the same as the outer safe margin. Binding, folding, creep, and the chosen paper can require additional allowance near the spine or fold. Use the booklet template or binding specification rather than applying one margin to every edge.
Page Order and Printer Spreads
Unless the manufacturer specifically requests imposed spreads, submit booklet pages as individual pages in reading order. Do not move page 2 next to page 15 simply because that is how a saddle-stitched sheet may be imposed later.
Saddle-stitched booklets often require a page count in multiples of four, but this depends on the binding and production method. Confirm the requirement before adding blank pages.
For booklets and instruction manuals, check cover setup, page count, page order, bleed, binding margin, barcode placement, and whether the cover uses a different stock or finish.
PDF Export for Card, Box, and Booklet Files
PDF/X-1a and PDF/X-4 are both used in commercial printing. PDF/X-1a generally uses a flattened workflow, while PDF/X-4 can preserve live transparency in a compatible color-managed workflow. Neither standard is automatically the best choice.
Use the PDF standard specified by the manufacturer. Do not flatten transparency, convert all RGB images to CMYK, add crop marks, or discard color profiles just because a generic export tutorial recommends it.
| PDF check | Practical requirement |
|---|---|
| Page or artboard size | Matches the supplied card, box, or booklet template and does not change during export. |
| Bleed | Included at the amount specified for the product and material. |
| Printer’s marks | Added only when requested. Crop marks are not automatically required. |
| Fonts | Embedded or converted according to the production workflow; no substitutions remain. |
| Images | Placed images are present, correctly clipped, and have suitable effective resolution at final size. |
| Color | Follows the agreed RGB, CMYK, spot-color, or specialty-ink workflow. |
| Production layers | Cut, crease, fold, perforation, foil, UV, white ink, and other masks are separated and named as required. |
| Final inspection | The exported PDF has been opened independently and checked page by page. |
Color, Resolution, Fonts, and Special Layers
These technical settings matter because they change how the card, box, or booklet is manufactured. They should support the product file rather than become a separate theory lesson.
RGB and CMYK
RGB is designed for light-emitting displays. Commercial printing commonly uses CMYK process inks, but some color-managed workflows accept RGB source content and convert it during prepress. RGB is not automatically a defective file.
Follow the manufacturer’s color requirement. Do not blindly convert every image before asking which profile, ink set, stock, coating, and proofing method will be used. Highly saturated screen colors may change when converted to the printable color range.
For brand colors or specialty inks, confirm whether a named spot color or a physical proof is required. A Pantone reference improves communication but cannot remove differences caused by paper, ink, coating, lighting, or production conditions.
Effective PPI
Around 300 PPI at final placed size is a common target for detailed print artwork, but it is not a universal pass-or-fail rule. A 300 PPI image enlarged to 200% has an effective resolution of approximately 150 PPI. Changing the metadata back to 300 PPI does not restore lost detail.
Fonts
Embed fonts or convert them to outlines only as the workflow requires. Do not outline text blindly: embedded text can remain searchable and editable, while outlined text prevents font substitution but makes corrections harder. Always retain an editable source file and proof the text before outlining.
Black and Overprint
Use the black build specified for the project. 100% K black is often suitable for small text and fine lines; rich black may be used for large solid areas when approved. A rich-black formula from another printer is not a universal standard.
Check overprint preview and separation preview. White objects set to overprint can disappear because white usually represents the absence of process ink. Black text may overprint in some workflows, but large black objects and color-critical elements require separate review.
Special Finishes
| Finish | File preparation |
|---|---|
| Foil stamping | Provide a separate solid vector mask or finishing layer with the required name. |
| Embossing or debossing | Provide separate vector artwork for raised or recessed areas; confirm detail and depth limits. |
| Spot UV | Provide a separate mask showing the exact coated areas. |
| White ink | Provide a separately named white-ink separation and identify whether it is an underbase or visible artwork. |
| Holographic material | Align artwork to the supplied material or finishing template and confirm pattern direction and registration. |
| Die-cutting | Keep cut, crease, perforation, window, and hole paths on the specified production layer. |
File Preparation by Product
| Product | File checks that matter most | Relevant EzraCard page |
|---|---|---|
| Playing cards | Finished size, trim path, safe area, bleed, corner radius, shared backs, face sequence, and card-back orientation | Custom Playing Cards |
| Game cards | Multiple designs, front/back pairing, file naming, quantity of each design, sequence, and variable information | Custom Game Cards |
| Trading cards | Numbering, rarity or variants, shared and unique artwork, finishing masks, and serialized data | Custom Trading Cards |
| Tarot cards | Large-format artwork, border tolerance, deck order, guidebook references, and packaging | Custom Tarot Cards |
| Card boxes | Approved dieline, panel orientation, cut, fold, crease, glue areas, barcode, bleed, and finishing masks | Custom Card Boxes |
| Instruction booklets | Finished page size, page count, reading order, binding margin, bleed, cover setup, and spine when applicable | Booklets and Instructions |
Use the Current Production Template
Templates are not decorative guides. They contain production dimensions and operations that affect the final product.
A card template may contain a trim path, safe-area guide, bleed boundary, corner radius, front/back orientation, and finishing notes. A box template may contain panel dimensions, cut lines, creases, folds, glue flaps, windows, and barcode areas. A booklet template may identify page size, cover setup, binding margin, and bleed.
Download the relevant file from EzraCard templates. If the project has a custom card size, special shape, unusual card count, custom packaging, or multiple components, request a project-specific template before finishing the design.
Do not resize a template, move its production guides, rename its special-color layers, or delete its notes without approval. If a guide is not intended to print, keep it on the supplied non-printing or production layer.
Preflight Checklist for Print-Ready Files

| Special finishes | Foil, UV, embossing, white ink, holographic, screen-printing, and die-cut layers are separate and correctly named. |
| Overprint | White objects, black text, spot colors, and other overprint settings have been reviewed in separation preview. |
| Final PDF | The requested PDF standard is used, unwanted marks are absent, and every page has been opened and inspected. |
Common Print-File Problems
| Problem | Production consequence | Practical fix |
|---|---|---|
| Treating the bleed boundary as the trim line | The finished product can be cut at the wrong position or the artwork can be undersized. | Keep the actual trim line at the finished size; use the outer boundary only for bleed. |
| No bleed | Cutting variation can expose a white or unprinted edge. | Extend edge-to-edge artwork through the specified bleed. |
| Text on a fold or near a cut | Text, logos, or numbers can look uneven or become unreadable. | Move critical content into the template’s safe area and binding margin. |
| Using a generic box rectangle | Panels, folds, glue areas, and finished dimensions will not align. | Use the approved box dieline for the actual material and card quantity. |
| Submitting booklet spreads without approval | Pages can appear in the wrong order during imposition. | Submit individual pages in reading order unless printer spreads are requested. |
| Using a small web image | Printed artwork can appear soft or pixelated. | Use original artwork and check effective PPI at final size. |
| White artwork set to overprint | The white object can disappear from the final output. | Inspect overprint preview and confirm the intended knockout behavior. |
| Dieline or foil mask included in CMYK | Production guides or finish shapes can print as visible artwork. | Keep production paths and finish masks on the required separate layers or separations. |
| Changing an online Rich Black formula | Ink coverage or registration may not suit the press or substrate. | Use the black build specified by the manufacturer. |
