Providing the correct design file format is crucial for smooth production when working with Taiwan packaging factories. Based on RTADV production data, roughly 30% of first-time overseas orders experience delays due to file format issues—wrong color mode, missing fonts, or incompatible software versions. This guide explains which file formats Taiwan factories prefer, how to prepare your files for Taiwan’s specific print workflows, and common mistakes to avoid.
Adobe Illustrator (.ai) — The Gold Standard
Adobe Illustrator (.ai) is the preferred file format for virtually all Taiwan packaging factories. Illustrator files preserve vector graphics at infinite resolution, support precise CMYK color specifications, and allow factories to easily adjust die-lines and prepare files for plate-making. Based on RTADV production data, over 85% of orders that proceed to production without file revisions are submitted as properly prepared .ai files. When submitting .ai files, convert all fonts to outlines, embed all linked images, and ensure the color mode is set to CMYK.
If you use Illustrator, save your file in a version compatible with CS6 or later for maximum compatibility. Older file versions may lose certain effects or transparency settings when opened on the factory’s system. Also note that Taiwan factories impose standard sheet sizes on press—the two most common are 菊版 (636 x 939 mm) and 四六版 (788 x 1,091 mm). Your artwork dimensions do not need to match these sheet sizes, but understanding them helps when your factory explains paper usage and pricing: a design that fits efficiently within a 菊版 or 四六版 sheet will yield a lower per-unit paper cost.

PDF Files — The Universal Alternative
If you do not use Illustrator, a press-quality PDF is the best alternative. When exporting a PDF for print, use the PDF/X-1a or PDF/X-4 standard, which embeds all fonts and images while maintaining CMYK color fidelity. Set the resolution to 300 DPI minimum for raster elements and ensure bleed marks are included (3 mm bleed on all sides is the Taiwan industry standard).
PDFs exported from InDesign, CorelDRAW, or other design software are generally well-accepted by Taiwan factories, as long as they meet the resolution and color mode requirements. Avoid PDFs generated from Microsoft Word or PowerPoint—these are not suitable for professional printing. According to the Taiwan Packaging Association (台灣包裝協會), PDF/X-4 is increasingly preferred over PDF/X-1a because it supports live transparency and ICC color profiles, reducing the chance of flattening artifacts on complex packaging artwork.

Other File Formats: When and How to Use Them
TIFF (.tif) files at 300 DPI in CMYK are acceptable for photographic elements but are not ideal as standalone packaging artwork files because they lack vector elements. PSD (Photoshop) files can be used for image-heavy designs but should be flattened and saved at 300 DPI in CMYK with bleed included.
EPS files are still accepted by some Taiwan factories but are increasingly being replaced by AI and PDF workflows. CorelDRAW (.cdr) files are used by a minority of factories—if your design is in CorelDRAW, it is safer to export a press-quality PDF rather than sending the native .cdr file. Based on RTADV production data, fewer than 5% of Taiwan packaging factories still accept .cdr natively; the rest require conversion.
Never send files in JPEG, PNG, GIF, or BMP format for production printing. These formats are lossy, low-resolution, and use RGB color space by default. They are only acceptable for reference purposes or initial mockup discussions. If you need to include a Pantone spot color in your design (for example, a brand logo that must be exact), note that each spot color plate carries an additional surcharge of approximately NT$500–2,000 per color, so always confirm with your factory during quoting.
（中文補充：TIFF 和 PSD 可用於照片元素但不是最理想的包裝設計格式。CorelDRAW 檔案建議轉出 PDF 再提交。JPEG、PNG 等格式僅能用於參考，不能用於印刷生產。Pantone 特別色每色加收約 NT$500–2,000 版費。）
Frequently Asked Questions
Q: What happens if my file uses RGB with Pantone references?
This is a common scenario when designers set the document to RGB but assign Pantone swatches to specific elements (e.g., a logo). Based on RTADV production data, this mismatch accounts for about 15% of pre-press revision requests. The factory’s pre-press team will convert the RGB artwork to CMYK, but the Pantone-referenced elements may lose their spot-color designation in the process—meaning they get converted to a CMYK approximation instead of printing as a true spot color. To avoid this, always set your document to CMYK mode from the start, and define Pantone colors as spot swatches (not process). If you want the Pantone color to print on a separate plate, confirm this with the factory and note the surcharge of NT$500–2,000 per spot color plate.
（中文補充：如果設計檔設定為 RGB 但指定了 Pantone 色票，轉換 CMYK 時特別色定義可能遺失。建議從一開始就設為 CMYK 模式，並將 Pantone 設為特別色色票（非四色）。）
Q: How do Taiwan factories handle files from Chinese or Japanese design software?
Taiwan factories regularly receive files created in Chinese-market software (such as CorelDRAW Chinese editions or local layout tools) and Japanese pre-press workflows. Based on RTADV production data, files from mainland Chinese designers sometimes use GB/T paper size standards or non-standard bleed settings that differ from Taiwan’s conventions. Japanese files may arrive in formats optimized for Japanese press standards (such as Japan Color 2001 Coated profiles). In both cases, the safest approach is to export a press-quality PDF/X-4 with fonts outlined and images embedded. If your designer works in a non-Adobe environment, ask them to also supply a high-resolution TIFF as a visual reference so the factory can verify that the PDF matches the intended design.
Q: My packaging uses a non-standard size. How should I set up the artboard?
Request a die-line template from your factory before starting your artwork. Taiwan factories typically provide an .ai or PDF template showing the cut lines, fold lines, glue flaps, and safe zones specific to your box dimensions. Set your Illustrator artboard to match the template exactly, place the die-line on a separate layer (usually labeled “die-line” or “刀模線”), and add 3 mm bleed beyond the outermost cut line. Keep in mind that Taiwan printing presses use standard sheet sizes—菊版 (636 x 939 mm) or 四六版 (788 x 1,091 mm)—so the factory will arrange (拼版) multiple units per sheet. You do not need to do imposition yourself; just submit single-unit artwork on the die-line template.
（中文補充：非標準尺寸的包裝請先向工廠索取刀模線模板（.ai 或 PDF），設定畫板尺寸與模板一致，刀模線放在獨立圖層，出血 3mm。工廠會依菊版或四六版紙張做拼版安排。）
What RTADV Recommends
At RTADV, we have processed thousands of packaging files from clients across North America, Europe, Japan, and Southeast Asia. In our experience, the single highest-impact step you can take is to request our die-line template before you begin designing. This eliminates sizing errors, ensures correct bleed, and saves an average of 3–5 working days in pre-press revisions. We provide die-line templates as editable .ai files at no charge. If your design team works in software other than Illustrator, we recommend exporting a PDF/X-4 with all fonts outlined—this has proven to be the most reliable cross-platform format in our production workflow. For clients unfamiliar with CMYK conversion, our pre-press team reviews every file and flags potential color-shift issues before printing begins, so you always have a chance to approve adjustments.

When This Guide Doesn’t Fit Your Project
This guide covers most starter brands and flexible inventory scenarios, but the following are not the right fit — consider alternative suppliers or materials to avoid procurement delays or budget overruns:
- Single SKU annual volume stable above 50,000 units (direct mass production unit cost is lower; small-batch sourcing is not cost-effective)
- Long-term reorders with unchanged specs (no need to resample for evergreen products; the proposal flow is overkill)
- Pure glass / plastic bottles / metal canister sourcing (paper packaging factory MOQ doesn’t fit; find material-specific specialists)
- Pure accessory sourcing (cards, stickers, manuals, corrugated cartons) — use accessory-specific channels
- 45+ day cross-border ocean freight (paper is moisture-sensitive; consider metal / plastic containers or special treatment)
