The vocabulary that shows up on every print-ready checklist, without the jargon. Bookmark this if a print shop ever sends you an email full of these words.
How many pixels of your image get packed into one printed inch. The same file can look razor-sharp printed small and pixelated printed large, because the pixel count stays fixed while the print size changes.
The actual width and height of a raster image, measured in pixels — for example, 3000 × 2000. This number, not the DPI metadata tag, is what determines maximum print quality.
The color model presses actually use: cyan, magenta, yellow and black ink combined on paper. Files meant for print should be converted to CMYK, since colors can shift when a printer converts an RGB file for you.
The color model screens use: red, green and blue light. Every AI image generator exports in RGB by default, which is exactly why the colors sometimes look different once printed.
Artwork that extends past the trim line of the final piece. It exists because cutting machines drift by a fraction of a millimeter, and bleed means that drift never shows up as an unwanted white edge.
The zone just inside the trim line where nothing important — text, logos, faces — should sit, in case the cut lands slightly off.
Artwork built from mathematical paths (lines, curves, shapes) instead of a pixel grid. It can scale to any size, from a favicon to a billboard, without losing sharpness.
Artwork built from a fixed grid of pixels — every photo, and every AI-generated image. It has a maximum usable size before it starts to look soft or blocky.
A PDF built to the specific requirements of the printer or product running the job: correct size, CMYK color, embedded fonts, and bleed included. Exact requirements vary by shop and by product, which is why it's worth confirming before a large run.
Text converted from live, editable type into vector shapes. Printers don't have your fonts installed, so outlining text before sending a file prevents it from silently substituting a different typeface.
A small file embedded in an image or PDF that tells a printer or monitor exactly how to interpret its colors. A CMYK file without one can still print fine, but an embedded profile removes the guesswork for the print shop's software.
Process color builds every shade from four inks (CMYK) layered together. A spot color is one single, pre-mixed ink — like a Pantone shade — used when a color needs to match exactly every time, such as a logo's brand color.
A family of PDF sub-formats built specifically for print (PDF/X-1a, PDF/X-4 and others), which enforce things like CMYK color and embedded fonts so a file can't silently go to press broken. Many print shops ask for a PDF/X file specifically.
COMMON QUESTIONS
The four questions people ask most before they've even opened a glossary term above.
Artwork that extends past the trim line of the final printed piece. Cutting machines can drift by a fraction of a millimeter, so bleed means that tiny shift never shows up as an unwanted white edge on the finished piece.
A full-bleed design covers the entire page edge to edge, with no border or margin, and extends slightly past the trim line on every side. It's standard for posters, edge-to-edge business cards, mugs, and most print-on-demand products.
RGB is the color model screens use: red, green and blue light. CMYK is the color model a printing press actually uses: cyan, magenta, yellow and black ink on paper. Every AI image generator exports in RGB by default, which is why colors can shift once a file is printed.
At least 300 DPI at final print size for close-up items like business cards or labels. For anything viewed from a few feet away, like a poster or banner, 100–150 DPI is usually enough.
