Vector vs. Raster: Which File Format for Packaging?

The vector vs. raster decision is one of the most important choices you make before printing, because the file type you send decides whether your custom printed boxes for your product print crisp or blurry. Getting it right is mostly about using vector artwork where you can and high-resolution raster images where you must. This article goes deeper than the file section of our main artwork and dieline guide, so you understand exactly what print resolution your packaging needs.

Vector artwork

Vector files (AI, EPS, or vector PDF) are built from mathematical paths, not pixels, so they scale to any size without losing sharpness. Blow a vector logo up to billboard size or shrink it onto a lip gloss box and the edges stay perfectly clean. That makes vector the preferred format for packaging: it is ideal for logos, type, and line art, and it lets a print operator resize your mark to fit any panel without quality loss. Vector is also how a printer separates spot colors and builds the cut path, which is why it is the gold standard for anything that must be sharp.

Raster images

Raster files (JPG, PNG, PSD, TIFF) are made of a fixed grid of pixels, so they blur, pixelate, or show jagged edges if you scale them up beyond their native size. Raster is the right choice for photographs, textures, and gradients – anything with continuous tone that vector cannot describe. The catch is resolution: supply raster art at a minimum of 300 DPI at final print size, not pulled small from a website. A web image is typically only 72 DPI and sized for a screen, so it will look soft and blocky once it is enlarged onto a box.

Why 300 DPI matters

DPI (dots per inch) measures how many pixels fall into each inch of the printed area. At 300 DPI the dots are small and dense enough that the human eye reads them as a smooth, continuous image; below roughly 200 DPI you start to see softness, and at web resolution the pixels become obvious. The number that matters is DPI at final print size, not the raw pixel count alone. A 1000-pixel-wide image is plenty for a two-inch panel but far too small for a ten-inch one. When in doubt, design at the true size the art will print and check the effective resolution there.

Which to use when

• Logos, text, icons – vector, always.
• Photographs, gradients, textures – raster at 300 DPI or higher.
• Mixed designs – build a vector layout and place high-resolution raster images into it.

Vector vs. raster at a glance

A common mistake: the web logo

The single most frequent file problem we see is a logo saved only as a small PNG or JPG pulled from a website or social profile. It looks fine on screen but turns soft and jagged once it is enlarged onto a printed panel. The fix is to use the original vector version of the logo – the file your designer first created it in. If that file no longer exists, do not simply enlarge the small image; it cannot recover detail that was never there.

Only have a logo?

If your logo exists only as a small web image, we can often recreate it as clean vector artwork as part of our free design support – just ask. Once it is vector, it can sit crisply on a box of any size, get separated into spot colors, and be reused across every product you launch. See dieline templates for where the artwork goes on the box, and our bleed and safe zone notes for keeping it inside the printable area.

Get colors right too

File type controls sharpness, but color mode controls accuracy. Print uses CMYK and spot colors, not the RGB your screen displays, so a design that glows on a monitor can shift on press. Build or convert your artwork in CMYK, and specify Pantone references for brand-critical colors. Our CMYK vs. Pantone guide explains when to use each so your printed box matches what you approved.

How to package your files before sending

Sharp art still needs to arrive intact. When you send a layout, keep the original editable vector file rather than a flattened export, and either embed or outline your fonts so a missing typeface does not reflow your text on press. Place high-resolution raster images at their full native size, not stretched up to fit. Include the colors you expect – CMYK build values and any Pantone references – and supply a PDF proof that shows how the final box should look. Packaging the files this way means fewer back-and-forth rounds, a cleaner first proof, and a printed box that matches what you approved. If your art is not print-ready, our free design support can prepare it for you; just flag what you are unsure about and send everything you have.

Frequently asked questions

What is the difference between vector and raster?

Vector art is built from scalable math paths and stays sharp at any size, while raster art is built from a fixed grid of pixels and blurs when enlarged beyond its native resolution.

What resolution do my packaging files need?

Vector art needs no set resolution because it scales freely. Raster images should be at least 300 DPI at the final print size; web images at 72 DPI are too low.

Can you fix a low-resolution logo?

Often yes. As part of free design support we can frequently redraw a small web logo as vector so it prints crisply at any size. Send us what you have and we will tell you.

What file formats should I send?

Send vector logos as AI, EPS, or vector PDF, and any photos or textures as 300 DPI raster files. A vector layout with high-resolution images placed in is ideal.
