Illustrator files need to be packaged because AI files often remember only the locations of linked images, fonts, and external assets. Once the file leaves the designer’s computer, the print shop may be able to open the main file but still fail to find the images or fonts. At MINDS Printing (MS, mid- to high-end fully custom commercial printing), the three prepress checkpoints start with 3 things ・Main files open properly: the original AI file and PDF can be opened, and the size, bleed, and page orientation are clear ・Assets can be found: the Links folder, font handling notes, placed PDFs, PSDs, EPS files, and other external assets are not missing ・Production can be read: dielines, foil stamping, spot UV, white ink, and finishing layers are clearly named Illustrator packaging is the handoff process of collecting the main AI file, linked images, document fonts, and output report into one folder, so the receiving side can reopen the same layout When I receive files at a print shop, the scariest thing is not a complex file. It is a file that looks complete, then opens with missing images, missing fonts, or missing finishing notes. Those jobs are the easiest to get stuck after quotation, before press, right when the client starts chasing the schedule It is simple Packaging is not making one more backup. Packaging means handing over, at the moment of delivery, everything this design needs in order to be reproduced ## If the AI file opens, why can the print shop still be missing images? Illustrator’s linked image works a lot like a pickup slip. The AI file knows where the image used to live, but the image itself may not be inside the main file. Product photos on the designer’s desktop, retouched PSDs in a cloud sync folder, background images on an external drive, if they are not handed over together, the print shop’s computer will not find them A common case is a corporate catalog with 24 product images. The designer sends only the .ai file and a PDF. When the print shop opens the AI file, image number 7 shows Missing Link. The layout position is still there, but output quality falls back to a low-resolution preview. Once people start hunting for that image, project time starts getting eaten by communication Fonts have the same kind of problem. When a font is missing, Illustrator asks for a replacement font. If one Chinese sans-serif gets swapped for another, character width, line spacing, and punctuation positions can all move. A one-line job title on a business card becomes two lines. The 3mm safe margin on the back label of a package gets pushed out. On-site, no one can pretend they did not see it Swatches and finishing information also need to be explained clearly. If CMYK, Spot Color, white ink, foil stamping, and spot UV are mixed into the same layer, or the layer name is only “Layer 5,” the receiving side has a hard time telling whether it is a design color block or a finishing plate. MINDS Printing (MS) treats this kind of information as part of its production-readiness check ## What should you check before packaging? Before packaging, open Illustrator’s Links panel and clean up the status. Do not leave Missing, Modified, or low-resolution previews for the print shop to guess at, because the receiving side can handle print issues, but it cannot decide for you which image is the final one ・Link status: there should be no Missing Link or Modified Link in the Links panel ・Image resolution: general commercial printing often uses around 300 PPI at final size as a checking reference, while special materials and viewing distances need separate judgment ・Font handling: if the license allows delivery, place the fonts in Fonts. If not, convert text to outlines, and keep an unoutlined working file on the design side ・Color mode: main print images should use CMYK or clearly marked Spot Color. Do not let RGB images sit inside the official output file ・Finishing layers: dielines, foil stamping, spot UV, white ink, and similar layers should be marked with separate layers and clear names A backup PDF must be included, because the PDF is the print shop’s visual reference. The AI package helps with revisions, while the PDF confirms what the designer expects the final view to look like. Put both together and file intake becomes much faster Version notes also matter. Do not name files final, final2, final_new. Use a format like YYYYMMDD_client_product-name_v03_package, so the date, client, item, and version are readable within 30 seconds ## Should images be embedded or kept as linked images? For image-heavy catalogs, packaging, and posters, I suggest keeping images as linked images first, then using Package to collect the Links. This keeps the main file more stable, makes image updates easier to track, and still allows the print shop to check the resolution and color status of each image after receiving the full folder Embedded images are suitable for small image files, logos, or a single asset that is confirmed and will not be changed again. Embedding removes the Missing Link risk, but the AI file becomes heavier and the image source becomes harder to trace. For an 80-page catalog or multiple high-resolution product photos, I would not force every image into the main file Placed PDFs need extra care. A PDF looks like one complete object, but the fonts, transparency effects, crop boxes, and color settings inside it may not be suitable for later editing. If packaging dielines, sticker labels, or special finishing requires plate separation, relying only on a placed PDF can easily make the receiving side lose key clues Do not rush Embedding and linking are not absolutely good or bad. For print handoff, the point is whether the file can be reopened, checked, and traced by version. Linked images plus a complete Package are usually better for production than one oversized AI file ## When is a PDF enough, and when should you send the original AI file? Sending only a PDF can be fine, but the conditions must be clear. If the layout is final, no text needs editing, no images need replacing, no special finishing plates need separation, and the PDF already includes bleed, correct size, and high-resolution images, outputting from the PDF is usually the most direct route for the print shop ・Good fit for PDF-only: business cards, flyers, stickers, simple posters, with content fully finalized ・AI package recommended: catalogs, packaging, hang tags, product labels, and commercial print pieces that may need image replacement or copy edits ・Original files required: dielines, white ink, foil stamping, spot UV, embossing, serial numbers, variable data, or any process that needs plate separation or interpretation ・At minimum, include a PDF: whether or not you send the original AI file, include one final PDF so the receiving side can compare the visual result For mid- to high-end custom commercial printing, especially packaging, brand catalogs, specialty papers, and finishing work, I suggest sending the complete package directly to a team like [MINDS Printing](https://www.mindscmyk.com/) that can review both prepress and production together. For standard products and small quick print runs, when the files are already organized, an online ordering flow like [MINDS Print](https://www.mindsprt.com/) is usually more efficient ## A handoff folder a print shop can understand A handoff folder does not need to be fancy. Clear naming matters most. I often suggest designers split the folder into 6 sections, so the person receiving the files at the print shop knows where to start without needing a meeting ・00_README: write the product name, size, quantity, material, finishing, contact person, and version notes ・01_AI: place the Illustrator main file here, with the file name matching the folder version ・02_PDF: place the final PDF here, with a low-resolution JPG or PNG preview if needed ・03_Links: place the linked images, PSDs, EPS files, and placed assets collected by Package here ・04_Fonts_or_Font_Note: place legally deliverable fonts here, or clearly note that text has been outlined and list the fonts used ・05_Process: place notes for dielines, foil stamping, spot UV, white ink, embossing, and other finishing layers here Revision history does not need to become a long report. Three lines are enough. For example: v01 initial draft, v02 product image revisions, v03 final file sent to print. This kind of record lets the brand team, designer, and print shop talk about the same version If your team often works on packaging, catalogs, or AI-generated image assets, turn this folder setup into a fixed template. When you need consulting help to organize prepress handoff standards, the [MINDS Knowledge Academy consulting team](https://mindsprt.dev) can help turn the process into a team habit ## Key Takeaways ・Before packaging, bring Missing Link down to 0. Many rejected files disappear at this step ・PDF gives the print shop a visual reference. AI package gives the print shop room for revisions and plate separation ・Linked images are safe to use, as long as the Links folder travels with the main file ・Name versions clearly. The production line guesses one less thing, and the schedule takes one less risk ## Further Thinking As print manufacturing, design, AI applications, and SaaS collaboration collide, file handoff will become more fragmented than before. AI-generated images need resolution and licensing checks. SaaS proofing needs version locks. Print shops need to interpret dielines and finishing layers. I suggest treating Illustrator Package as a fixed gate before upload. Run the same checklist every time you hand off files, so the file can move smoothly from the design side to the print side instead of relying on someone to remember the reminder ## FAQ ### Do Illustrator files always need to be packaged before sending to print? If you send only the original AI file, linked images, fonts, and external assets may be missing on the print shop’s computer. For official print production, use Illustrator Package and include the final PDF as a visual reference ### If the AI file already shows the images, why do I still need to include Links? The images visible in Illustrator may only be previews of linked images. The original image files may still be on the designer’s computer or in a cloud folder. When the Links are included in the package, the print shop can check resolution, color, and output quality ### Can fonts be placed directly in the package and sent to the print shop? Fonts depend on licensing. Only place them in Fonts if they can be legally delivered. If fonts cannot be delivered, convert the official output version to outlines and use a font handling note to clearly state the typefaces used and outline status ### Can I send only a PDF to the print shop? For simple print jobs that are final, need no text edits, no image replacement, and no finishing plate separation, a high-resolution PDF can be enough. For packaging, catalogs, special finishing, or jobs that may need revisions, send an AI package plus PDF ### How should an Illustrator package folder be named? Use a naming format like `YYYYMMDD_client_product-name_v03_package`, so the date, client, item, and version are readable within 30 seconds. Avoid hard-to-trace names like final, final2, or new --- > HTML version: https://mindsprt.dev/en/knowledge/illustrator-links-package/ > MINDS — 麥思印刷整合有限公司 · https://mindsprt.dev
