Why Print Specifications Matter for Custom Tablecloths
A tablecloth is not a document you email to a colleague or post on a website. It is a large-format textile product printed by commercial dye-sublimation equipment, finished with hemming and optional features, and expected to represent your brand accurately at events, trade shows, and customer-facing settings for years. The technical requirements for artwork that goes into that process are therefore completely different from the requirements for digital design.
When customers send us artwork — particularly AI-generated content — the most common issues all come down to specifications. The image looks perfect on screen but fails in production because it was built to screen standards rather than print standards. This guide explains exactly what we need and why, so you can either prepare your own files correctly or hand us your AI brief with confidence that we know how to convert it properly.
If you have arrived here from an AI design tool and are wondering how to turn your concept into a finished product, our AI design conversion service handles the entire technical process for a fixed fee.
Pantone Coated Colours: The Standard We Print To
Colour accuracy on printed textiles is one of the most technically demanding aspects of our work, and it is the area where AI-generated designs most commonly fall short. Here is why Pantone Coated colours are the required standard and what the alternatives mean in practice.
What Pantone Coated Means
Pantone is a standardised colour matching system used globally across the print, textile, packaging, and manufacturing industries. Each colour is assigned a unique reference number — for example, PMS 286 C is a specific, clearly defined shade of blue. When we receive a Pantone reference, we know precisely what ink mixture and calibration to use on our dye-sublimation equipment to reproduce that colour accurately on polyester fabric. The “C” suffix denotes the Coated version, which is the standard for most hard-surface and textile printing applications.
Why RGB and Hex Codes Are Not Sufficient
RGB (Red, Green, Blue) is the colour model used by screens — monitors, phones, tablets. Hex codes are simply a shorthand notation for RGB values. Both are designed to describe how light is mixed on a display, and they have no direct physical equivalent in print. The same hex value can look noticeably different on a MacBook, an Android phone, and a Windows monitor. More critically, the RGB colour space is significantly larger than the gamut achievable in print, meaning some colours that look vibrant on screen simply cannot be reproduced accurately on fabric. Without a Pantone reference, we are essentially guessing at your intended colour based on a screen value, which is not acceptable for branded promotional materials.
How to Find Your Brand’s Pantone References
If your brand was designed professionally, your brand guidelines will include Pantone references alongside your RGB and Hex codes. Check any brand identity document, logo usage guide, or contact your original designer. If you do not have Pantone references, we can help you identify the closest Pantone match to your existing brand colours as part of our conversion service — this is one of the most common tasks we perform for customers converting AI briefs to print-ready files.
CMYK: A Secondary Option
CMYK (Cyan, Magenta, Yellow, Key/Black) is the four-colour print model used in offset and digital printing. It is closer to the physical reality of ink mixing than RGB and is acceptable for our purposes, though Pantone remains the preferred and most accurate standard for brand colour work. If you are supplying CMYK values, please ensure they are specified in your file rather than converted from RGB at the last stage.
Vector Files: What They Are and Why You Need Them
The single most common reason we cannot print from a supplied file — including AI-generated images — is that the artwork is a raster (pixel) file rather than a vector file. Understanding this distinction is fundamental to understanding why your AI tablecloth mockup, however good it looks on screen, is not print-ready.
Raster Files (Pixel-Based)
Raster files are made up of a fixed grid of pixels. Every digital photograph, every AI-generated image, every screenshot, and every file saved as JPG, PNG, WEBP, GIF, or TIFF is a raster file. The image has a fixed resolution — say, 1200 pixels wide — and if you try to print it at 6 feet wide, those 1200 pixels are stretched across 72 inches, resulting in a blurry, pixelated, and unprofessional result. You cannot recover detail that was never in the file.
Vector Files (Path-Based)
Vector files are built from mathematical descriptions of shapes, lines, and curves called paths. Because they are described mathematically rather than as a fixed grid of pixels, they can be scaled to any size — from a business card to a billboard — with no loss of quality. The file formats that use vector data are .AI (Adobe Illustrator), .EPS (Encapsulated PostScript), and properly structured .PDF files. SVG files are also vector-based but are primarily used for web applications and require conversion for production.
Why AI-Generated Images Are Always Raster
AI image generation tools, including Midjourney, DALL·E, Stable Diffusion, and the image generation features in Claude, produce raster images. There is no AI tool currently available that outputs true vector artwork. An AI image that “looks like” a logo or graphic is still a grid of pixels describing that graphic, not the mathematical paths that professional printing requires. Vector conversion requires a human designer working in Adobe Illustrator or CorelDRAW to retrace the artwork as paths — this is exactly the service we provide.
Your Logo Must Be a Proper Vector File
If your logo was designed professionally, you should have a .AI, .EPS, or .PDF file from your designer. If you only have a PNG or JPG of your logo, we will need to redraw it as a vector as part of our conversion process. A PNG logo embedded into an Illustrator file is not the same as a vector logo — the logo itself must be drawn in vector paths.
Resolution and Bleed Requirements
Resolution
For any raster elements included within a vector layout (such as a photographic background), the minimum required resolution is 150 dpi at the final print size. For a tablecloth that is 6 feet wide, this means the image must be at least 150 pixels per inch across the full 72-inch width — a minimum of 10,800 pixels wide. AI-generated images are typically 1024×1024 or similar, which at tablecloth dimensions equates to approximately 14 dpi. This is unusable for production.
Pure vector artwork has no resolution constraint — this is one of the primary reasons vector files are mandatory for logos and graphic elements.
Bleed
Bleed refers to artwork that extends beyond the finished edge of the tablecloth. During production, tablecloths are hemmed and folded, which means a small amount of material is turned over at each edge. To ensure colour and design elements run right to the edge of the finished cloth without a white border appearing, the artwork must extend at least 1 inch beyond the finished dimensions on all sides. This is built into the document at the design stage, not added afterwards. AI mockups never include bleed.
Safe Zone
Correspondingly, any important content (logos, text, key graphic elements) should be kept at least 0.5 inches inside the finished edge to ensure it is not clipped during hemming. This safe zone is especially important for text and logos that appear near the edges of a tablecloth design.
Accepted File Formats
The following file formats are accepted for production:
- .AI (Adobe Illustrator) — Preferred format. Native Illustrator files preserve all vector data, layer structure, and embedded colour profiles. All fonts must be outlined (converted to paths) before saving.
- .EPS (Encapsulated PostScript) — Industry standard vector format compatible with most professional design applications. Fonts must be outlined.
- Vector .PDF — PDF files that were exported from Illustrator or CorelDRAW with vector data intact are acceptable. PDFs created by scanning, screenshot, or export from non-vector applications (including Microsoft Word, PowerPoint, or Canva’s standard export) may not contain usable vector data.
- CorelDRAW .CDR — Acceptable with fonts outlined and all elements embedded.
The following formats are not acceptable as final production files (though they are useful as references):
- JPG, JPEG — raster only, no vector data, lossy compression
- PNG — raster only, no vector data (despite sometimes having transparent backgrounds)
- WEBP, GIF, TIFF — raster only
- Microsoft Word .DOCX or PowerPoint .PPTX
- Canva standard export (unless specifically exported as PDF Print with fonts embedded)
- Screenshots or screen recordings of any kind
- AI-generated image files in any raster format
Fonts and Typography
Font handling is one of the most common sources of problems in print production. There are three related issues to be aware of:
Outline Your Fonts
Before supplying a vector file, all text must be converted to outlines (also called curves or paths). This converts the text from live, editable type into vector shapes. The reason is that font files are separate pieces of software — if we open your Illustrator file on our system and do not have the same font installed, the system may substitute a different font, changing the appearance of your design. Outlining eliminates this risk entirely. In Adobe Illustrator: Select All → Type → Create Outlines. In CorelDRAW: Select All → Arrange → Convert to Curves.
AI-Invented Fonts
AI tools frequently generate text that appears to be set in a specific typeface but is actually a pixel rendering of a made-up font that does not exist in any font library. We cannot match or reproduce an AI-invented font. When we convert an AI brief to a production file, we will discuss the typography with you and identify a real, licensed font that achieves the look you are after, or we will work from your brand’s specified typeface if you can supply it.
Font Licensing
All fonts used in production files must be properly licensed. If you are using a custom or purchased typeface, the licence must permit commercial use in print production. Standard system fonts (Arial, Helvetica, Times New Roman) and fonts from reputable free libraries (Google Fonts, for example) are generally fine for commercial print use, but always verify the licence terms if you are unsure.
Common AI Design Errors and How We Fix Them
This table summarises the most frequent technical problems we encounter with AI-generated artwork and what our conversion service does to resolve each one.
| AI Design Error | Why It Is a Problem for Print | How We Fix It |
|---|---|---|
| Hex or RGB colour codes only | Screen colours, cannot be reliably reproduced on fabric | We identify the correct Pantone Coated equivalent for your brand colours and build from that reference |
| Raster logo (PNG, JPG) | Pixelates when scaled to tablecloth dimensions | We redraw your logo as vector artwork in Adobe Illustrator |
| Low resolution (72–96 dpi) | Blurry and pixelated at large-format print scale | Raster elements are replaced with vector or with properly sized high-resolution source images where available |
| No bleed area | White edge appears after hemming | We extend the design to include a full 1-inch bleed on all sides within the production file |
| AI-invented fonts | Font does not exist, cannot be matched or reproduced | We identify a real equivalent typeface and discuss it with you before finalising |
| Misspelled text | AI frequently introduces typos in generated images | We review all text against your brief and correct any errors |
| Incorrect tablecloth dimensions | AI mockups are rarely built to accurate size ratios | We rebuild the layout to the exact dimensions of your chosen product |
| Layered elements misaligned | AI image composition looks right on screen but elements are not precisely positioned | We rebuild the layout from your AI reference with correct alignment and spacing |
| Missing brand guidelines compliance | AI may place logos in configurations that violate brand standards | We review against any brand guidelines you supply and adjust placement accordingly |
