Transfer Decal Artwork Requirements: File Types and Design Guidelines

Transfer Decal Artwork Requirements: File Types and Design Guidelines

Everything you need to submit print-ready artwork for transfer-cut decals and vinyl lettering

The core transfer decal artwork requirements are simple: send a vector file (AI, EPS or PDF) with all text converted to outlines and the cut line clearly marked, set up at the size you're ordering. Keep every letter at least 1/2 inch tall, leave at least 1/8 inch between characters, and keep strokes no thinner than 1/8 inch. The price includes 8 standard picks (the pieces weeded out after cutting), up to 40 picks per square foot; extra picks run $0.02–$0.04 each, and very intricate designs are custom quoted.

Transfer-cut decals are built from individual pieces of vinyl lettering or graphics that get lifted together on application tape and placed as one unit onto a car, window, wall, or piece of equipment. Because every letter and shape has to be cut, weeded, and masked separately, transfer decal artwork requirements are stricter than a standard printed sticker. This guide walks through the file formats, vector setup, text sizing, and cut line details our production team needs to turn your design into a clean, accurately spaced transfer decal. For the full technical specs, see our transfer-cut guidelines before you upload artwork.

Common Questions About Transfer Decal Artwork

What is the best file format for transfer decals?
Vector formats are required for transfer-cut decals: AI (Adobe Illustrator), EPS, or a vector-based PDF. Transfer decals rely on exact cut paths between letters and shapes, and only vector artwork gives our cutters clean, scalable lines. Raster files like JPG or PNG are fine for full-color printed decals but cannot be used for transfer-cut lettering because they have no cut path data built in.
Can I submit a JPG or PNG logo for a transfer decal, or does it need to be vector artwork for transfer decals?
If your logo only exists as a JPG or PNG, we can typically redraw simple designs into vector format, but this adds time and may incur a redraw fee for complex artwork. The fastest route is submitting native vector artwork for transfer decals in AI, EPS, or PDF with all text converted to outlines. If you're unsure which file you have, check our custom file setup page for format examples.
What is the difference between a decal and a transfer?
A standard die-cut or kiss-cut decal is one solid piece of printed vinyl, usually with a single background shape. A transfer decal is made of multiple separate pieces, like individual letters in a name or numbers in an address, that are pre-aligned on application tape so they go on as one unit. Transfers are commonly used for vinyl lettering on storefront windows, boats, and vehicles where there's no printed background color, just the vinyl letters themselves.
What are the instructions for transferring a decal once I receive it?
Each transfer decal arrives with three layers: the vinyl graphic, an adhesive backing, and application (transfer) tape on top holding every piece in place. You peel the backing, position the decal using the transfer tape as your guide, press it onto a clean surface, then slowly peel away the transfer tape, leaving the vinyl behind. Our transfer decal application page and how to apply a transfer-cut sticker video walk through the full process step by step.
Can I print my own rub-on transfers at home instead of ordering custom transfer decals?
Home rub-on transfer kits exist, but they're generally limited to small sizes, single colors, and short-term indoor use. Custom transfer decals from Decals.com are cut from professional-grade vinyl rated for multi-year outdoor exposure, available in sizes from Custom Transfer Decals starting at 3 inches up to 120 inches, and precision-cut to your exact artwork rather than hand-rubbed. If you need durable, weatherproof vinyl lettering for a vehicle, storefront, or sign, a printed transfer decal will hold up far longer than a DIY rub-on sheet.
How long after painting a surface can I apply a transfer decal?
Wait at least 2 to 4 weeks after painting before applying a vinyl transfer decal. Fresh paint continues to off-gas and cure during this window, and applying vinyl too soon can trap solvents underneath, leading to bubbling, poor adhesion, or paint damage when the decal is eventually removed. If the surface was clear-coated, follow the clear coat manufacturer's cure time as well.
What is the minimum text size and letter spacing for transfer-cut lettering?
We recommend a minimum letter height of 1/2 inch for transfer-cut text and at least 1/8 inch of space between individual letters. Thin script fonts, tightly kerned text, or small serif details below these thresholds become difficult to weed and may tear during application. If your design uses a connected script font, our team can add small bridges between letters to keep them stable on the transfer tape without changing the look of the final decal.

What Makes Transfer-Cut Decals Different From Other Decal Types

Transfer-cut decals are not a single printed shape like a die-cut decal or kiss-cut decal. They're made of separate vinyl pieces, usually letters, numbers, or line-art graphics with no solid background, that are cut individually, weeded by hand, and then masked together under one sheet of transfer tape. That tape holds every piece in its correct position so the whole design applies as a single unit directly onto glass, metal, a vehicle panel, or a wall. Because there's no background sheet to hide gaps or misalignment, transfer decal artwork requirements focus heavily on consistent spacing, clean vector paths, and enough structural connection between letters so nothing shifts before it reaches the surface. If you're deciding between cut styles for a project, our guide comparing custom vinyl decals and stickers breaks down when transfer cut makes more sense than die-cut or kiss-cut.

Best File Formats for Transfer Decal Artwork

Vector files are non-negotiable for transfer-cut decal setup. We accept AI and EPS files directly from Adobe Illustrator, along with vector-based PDFs exported at full resolution with all paths intact. An EPS file for transfer decals should have all fonts converted to outlines (so we're not missing a font on our end), all strokes converted to filled shapes, and any effects or gradients simplified into flat vector shapes. AI files for vinyl decals should be set up in CMYK color mode with Pantone or spot colors clearly labeled if you need exact color matching. Raster formats like JPG, PNG, or PSD can be used to reference a design concept, but they cannot be cut directly, since there is no path data describing where the vinyl should separate between letters. For a full breakdown of accepted formats and resolution requirements, visit our custom file setup page before submitting your order.

Text Sizing, Letter Spacing, and Font Choices

Text size, letter spacing, and font selection are especially important when designing transfer-cut decals. Unlike standard printed decals, transfer-cut designs consist of individual vinyl elements that must be weeded, transferred, and adhered to the application surface. Letters that are too small, lines that are too thin, or details that are too intricate can make a decal more difficult to produce, apply, and maintain over time.
Whenever possible, keep lettering at least 1 inch tall and allow a minimum of 1/8 inch of spacing between adjacent characters. These guidelines help ensure that excess vinyl can be removed cleanly during production while also making it easier to transfer and position each letter during installation.
Bold, sans-serif fonts are generally a better choice than thin scripts or fonts with delicate details. Thicker lettering provides more vinyl and adhesive surface area to bond with the application surface, helping individual elements stay securely attached. Very thin lines, small lettering, and intricate details have less adhesive contact area, making them more difficult to apply and potentially more susceptible to lifting, peeling, or premature wear.
If your design uses a connected script font, discreet bridges (small vinyl connectors) can sometimes be added between letters to help stabilize the design during production and application. This technique can be useful for custom vinyl lettering on storefronts, vehicles, and other surfaces.
Avoid placing very small text inside larger shapes or including tiny, isolated design elements. These details can be difficult to weed and transfer, and their limited adhesive surface area may affect how well they remain attached after installation. Designing with adequate size, spacing, and line thickness helps create a transfer-cut decal that not only looks good but is easier to install and better suited for long-term use. 

Setting Up Cut Lines and Weeding Areas Correctly

Cut lines help identify exactly where the vinyl should be cut to create your transfer-cut decal. While including cut lines in your artwork is a helpful best practice, you do not need to create or provide cut lines to place an order with Decals.com. Our customer service team consists of trained graphic designers who can assist with preparing your artwork for production.
If you're comfortable setting up your own cut lines, we recommend placing them on a separate, clearly labeled layer or using a designated spot color that our prepress team can easily identify. Cut lines should follow the intended edges of your design, with closed vector paths and no unintended overlaps. Properly prepared files can help streamline production and reduce the need for artwork adjustments.
For transfer-cut decals, the excess vinyl surrounding and between letters or design elements is removed during a process called weeding. This leaves only the intended lettering or graphics, which are held in position with transfer tape for application. Clearly defined shapes and adequate spacing between design elements make weeding easier and help create a decal that's easier for customers to apply.
If you don't know how to create cut lines, that's perfectly fine. Simply upload your artwork and make sure it's clear which parts of the design you want included in the finished decal. Our team can typically assist with setting up the necessary cut lines and preparing your file for production. If anything about the intended design or cut areas is unclear, we may reach out for clarification before printing.
