Preparing Artwork for Packaging | ILLING Packaging
Table of Contents
The single most common cause of a decoration job going sideways isn't the printing. It's the artwork. A logo pulled from a website at screen resolution, a file in the wrong color mode, text that isn't outlined, no bleed where the design runs to the edge: any one of these turns a clean print into a blurry, off-color, or delayed one. The good news is that preparing artwork for packaging decoration correctly is straightforward once you know what your decorator needs, and getting it right up front saves reprints, cost, and time.
This guide covers what makes artwork print-ready: file formats, resolution, color setup, and the details decorators care about. It's written for buyers and brand managers who want their packaging to come out looking like the brand they built, not a degraded copy of it. For the decoration methods this artwork feeds into, see our Decoration 101 guide and our guide to packaging decoration methods.
Why Artwork Preparation Matters So Much
Decoration reproduces exactly what you give it. A decorator can run a flawless print and still deliver a disappointing result if the file behind it was low-resolution, set up in the wrong colors, or missing the technical elements the process needs. The print quality is capped by the file quality, and no amount of skill on the equipment raises that cap.
This is why decorators ask for specific file types and specifications, and why "just send the logo" often isn't enough. The requirements aren't bureaucratic; each one prevents a specific, common failure. Understanding them lets you hand over artwork that prints right the first time, which is faster and cheaper than discovering a problem after setup.
The Core Requirements
Most decoration artwork comes down to a handful of specifications. Here are the ones that matter most.
| Element | What decorators generally want | Why it matters |
|---|---|---|
| File format | Vector (AI, EPS, PDF) where possible | Scales without quality loss |
| Resolution | High resolution (commonly 300 dpi) for raster images | Prevents blurry, pixelated prints |
| Color mode | CMYK or specified spot colors, not RGB | RGB shifts color when printed |
| Fonts | Outlined or provided | Prevents font substitution errors |
| Bleed | Included where the design runs to the edge | Prevents unprinted edges |
Vector artwork is the ideal for logos and graphics because it scales to any size without losing quality, unlike a raster image that pixelates when enlarged. Formats like AI, EPS, and print-ready PDF preserve vector data. When artwork must be raster, such as a photograph, it needs to be high resolution at the size it will print, commonly 300 dpi, because a low-resolution image that looks fine on screen will print blurry.
Color mode trips up many first-time submissions. Screens display color in RGB, but printing uses CMYK or specific spot colors, and RGB colors shift when converted for print. Providing artwork in the correct color mode, and specifying any exact brand colors, prevents the color you approved on screen from arriving different on the package. Fonts should be outlined or supplied, because if the decorator doesn't have your exact font, their software may substitute a different one and change how your design looks. And bleed, extra image beyond the trim edge, is needed wherever the design runs to the edge, so there's no thin unprinted strip if anything shifts slightly during production.
How Requirements Change by Method
Different decoration methods have somewhat different artwork needs, which is worth knowing before you prepare files.
Methods like silk screen printing often work in spot colors, one screen per color, so a design's color count directly affects the job, and artwork may need to be set up with that in mind. Full-color methods like digital printing handle complex, multi-color, and photographic artwork more readily, since they aren't built around one-color-per-screen. Label and shrink sleeve decoration have their own considerations for how artwork wraps, distorts, or positions on a curved or three-dimensional surface. The practical takeaway is to tell your decorator which method you're using, or ask them to recommend one, and prepare artwork to that method's requirements rather than a generic guess. A decorator who runs multiple methods in-house can guide this, as we cover in our guide on in-house decoration.
A Practical Pre-Submission Checklist
Before you send artwork to a decorator, running through a short checklist catches the common problems:
- Is the artwork vector where possible, or high resolution if raster?
- Is it in CMYK or your specified spot colors, not RGB?
- Are exact brand colors clearly specified?
- Are fonts outlined or included with the file?
- Is bleed included where the design reaches the edge?
- Have you confirmed the decoration method and its specific requirements?
- Have you included the dimensions and the container the artwork applies to?
If you can answer yes to these, your artwork is in good shape. If you're unsure on any of them, that's exactly the kind of thing to ask your decorator before the job starts rather than after.
Where ILLING Fits In
Good decoration starts with good artwork, and part of our job is helping customers get there. We tell you what we need before the job starts, flag artwork issues before they become reprints, and guide the file setup to match whichever decoration method fits your product. Because we run decoration in-house across silk screen, pressure-sensitive labeling, shrink sleeving, pail labeling, RFID, and digital printing, we can advise on artwork for the specific method your job calls for rather than handing you a generic spec sheet and hoping.
That guidance is part of what it means to have decoration and sourcing under one roof: we're involved early enough to catch the problems that cause delays and disappointing results, instead of printing exactly what came in and leaving you to discover the issue later. If you're not sure how to prepare your artwork, ask us. We'd rather spend ten minutes getting the file right than reprint a job that came out wrong.
Bring us your artwork and your product, and we'll make sure the decoration comes out looking like the brand you built.
FAQs
What file format should I use for packaging artwork?
Vector formats such as AI, EPS, or print-ready PDF are generally best for logos and graphics, because vector artwork scales to any size without losing quality or becoming pixelated. When artwork has to be a raster image, such as a photograph, it should be high resolution at the size it will actually print, commonly 300 dpi. The reason format matters is that decoration reproduces exactly what you provide, so a low-quality or improperly formatted file produces a low-quality print no matter how well the job is run. If you're unsure what format your specific artwork should be in, your decorator can tell you what they need before the job starts.
Why does my artwork need to be in CMYK instead of RGB?
Screens display color using RGB, but printing reproduces color using CMYK inks or specific spot colors, and colors shift when converted from RGB to print. If you submit artwork in RGB, the printed color may not match what you approved on screen, sometimes noticeably. Providing artwork already in CMYK, or specifying exact spot colors for your brand, lets the decorator reproduce the color you intend rather than a shifted version of it. Color accuracy is one of the most common sources of disappointment in decoration, and it usually traces back to color mode, so setting it correctly up front is worth the attention, especially for brand colors that must match exactly.
What resolution does packaging artwork need to be?
For raster images, high resolution at the final print size is the standard, commonly 300 dpi. Resolution matters because a low-resolution image that looks fine on a screen will print blurry or pixelated, since print requires far more detail than a screen display does. Vector artwork sidesteps this concern because it scales without any loss of quality, which is why vector is preferred for logos and graphics. The key point is that resolution must be measured at the size the artwork will print: an image that's high resolution at a small size can become low resolution when enlarged, so confirm resolution against actual print dimensions.
Do I need to outline fonts in my artwork?
Yes, outlining fonts, or providing the font files with your artwork, is standard practice. If the decorator doesn't have the exact font used in your design, their software may substitute a different font, which changes how your design looks, sometimes significantly. Converting text to outlines turns the letters into fixed shapes that render identically everywhere, eliminating the substitution risk. If you prefer to keep text editable, providing the font files along with the artwork is the alternative. Either way, the goal is ensuring the type in your printed packaging looks exactly like the type you designed, rather than a substituted approximation.
What is bleed and why does my artwork need it?
Bleed is extra artwork extended beyond the intended trim or edge of the printed area. It's needed wherever your design runs all the way to the edge, because production processes have slight tolerances, and without bleed, a small shift can leave a thin unprinted strip along the edge. By extending the design slightly past the edge, bleed ensures the color or image reaches the very edge cleanly even if there's minor movement during production. Not every job needs bleed; it matters specifically when the design reaches the edge rather than sitting within a margin. Your decorator can tell you how much bleed their process requires for your specific job.
